  • Fixed missing balloon tool tips in the SoundFont editor.
  • Added Huawei phone tools to the blacklist.

New in OmniMIDI 14.8.0.0 (Jun 22, 2023)

  • Fixed driver registration.
  • Fixed multiple issues.

New in OmniMIDI 14.7.1.0 (Apr 22, 2023)

  • Fixed regression that caused extremely slow playback in normal playback mode, even with MIDI Feedback disabled.

New in OmniMIDI 14.7.0.0 (Apr 19, 2023)

  • Updated libraries.
  • Fixed issue that caused the MIDI Feedback feature to stop working after restarting the synthesizer's engine.

New in OmniMIDI 14.6.14.0 (Sep 11, 2022)

  • Test fix for Windows 10/11 PnP registration. (From 14.6.13.127)
  • Fixed feedback mode. (From 14.6.13.127)
  • Added SoundFont 3.x support. (From 14.6.13.97)
  • Minor performance bump and bug fixes. (From 14.6.13.81)
  • Added Microsoft Teams and Mozilla Thunderbird to the blacklist. (From 14.6.13.97)
  • Applied minor fixes to the driver registration system. (From 14.6.13.81)
  • Added some Virtual Reality related executables to the blacklist. This should allow VR users to update the driver while wearing their HMD, without having to restart the compositor (e.g. SteamVR or Oculus). (From 14.6.13.77)
  • Made some changes to the driver registration system. (From 14.6.13.77)
  • Updated BASSMIDI to version 2.4.13.41. (From 14.6.13.51)
  • Added new asynchronous MIDI events processing mode, which will decouple the MIDI processing from the audio buffer. This should increase the "fineness" of the audio, by removing the limit on the amount of notes that can be played on each buffer sample. This leverages the new asynchronous flags implemented by Un4seen Developments in the latest test version of BASSMIDI. (BASS_MIDI_ASYNC and BASS_MIDI_EVENTS_ASYNC) (From 14.6.13.51)
  • The Windows Multimedia Wrapper for Black MIDIs has been merged with the driver library. That means that whenever you're patching a program with the Black MIDI patch, the configurator is effectively copying the driver to the MIDI app's root folder. The upside of this approach is a huge boost in performance, since there are less hoops between the MIDI app and OmniMIDI, but the downside is that the user will have to repatch everytime a new OmniMIDI update is released. (From 14.6.13.51)
  • Minor bug fixes here and there. (From 14.6.13.51)

New in OmniMIDI 14.6.13.127 Pre-release (Jul 18, 2022)

  • Made some changes to the driver registration system.

New in OmniMIDI 14.6.13.51 Pre-release (Apr 9, 2022)

  • Updated BASSMIDI to version 2.4.13.41.
  • Added new asynchronous MIDI events processing mode, which will decouple the MIDI processing from the audio buffer. This should increase the "fineness" of the audio, by removing the limit on the amount of notes that can be played on each buffer sample. This leverages the new asynchronous flags implemented by Un4seen Developments in the latest test version of BASSMIDI. (BASS_MIDI_ASYNC and BASS_MIDI_EVENTS_ASYNC)
  • The Windows Multimedia Wrapper for Black MIDIs has been merged with the driver library. That means that whenever you're patching a program with the Black MIDI patch, the configurator is effectively copying the driver to the MIDI app's root folder. The upside of this approach is a huge boost in performance, since there are less hoops between the MIDI app and OmniMIDI, but the downside is that the user will have to repatch everytime a new OmniMIDI update is released.

  • Fixed live changes system, it should crash less and also work more reliably. (From PR88)
  • Added small troubleshooting utility to the configurator. (From PR83)
  • Removed CookedPlayer when not using the Windows Multimedia Wrapper. Windows' own WinMM library handles MIDI_IO_COOKED by itself. (From PR79)
  • Added MIDI feedback option, that allows you to send the incoming MIDI data to another MIDI out device, like for example a virtual MIDI cable or a physical MIDI device like a piano. (From PR77)
  • Added support for linear attack phase and linear decay and release phases. You can enable them in the Settings tab. (From PR58 and PR70)
  • Fixed issue that caused BASSASIO to get freed with a delay, and crash the app during OmniMIDI's BASS check process (Where it checks if it has to load its own BASS libraries or use the app's already loaded ones). OmniMIDI would see BASSASIO loaded in memory and use GetModuleHandle on it (while BASSASIO was still freeing itself), causing a crash. (From PR49)
  • Rewritten XAudio 2.9 engine, and restored support for that engine on Windows 8.1 and older. (From PR46 and PR67)
  • Fixed race condition between the rendering threads and the stream health-check thread, that caused the driver to crash with an EXCEPTION_ACCESS_VIOLATION error when freeing the BASS libraries during the MIDI output closing process, when playing lots of notes (e.g. in Black MIDIs). The stream health-check thread will now wait for the rendering threads to close, before freeing up the BASS libraries. (From PR31)
  • Enabled Control Flow Guard. (From PR25)
  • Increased minimum system requirements to SSE2-capable CPUs. (From PR25)
  • Removed debug chime. (From PR25)
  • Updated BASS to version 2.4.16 U1, BASS_VST to version 2.4.1, BASSASIO to version 1.4.1, BASSenc to version 2.4.15 and BASSMIDI to version 2.4.13 U22 BASSMIDI contains more performance improvements for Black MIDI playback. (From PR23)
  • Reduced update rate of the stream health thread, which should increase the performance on BASS-related threads. (From PR17)
  • Removed useless features that no one used.
  • Rearranged settings in the configurator.

New in OmniMIDI 14.6.0.109 (Jul 20, 2021)

New in OmniMIDI 14.6.0.46 (Jul 12, 2021)

  • Fixed XAudio 2.9 support on Windows 8.1 and older.
  • Fixed issue that caused XAudio 2.9 to not output any audio when the ASIO Direct Feed mode was enabled.

New in OmniMIDI 14.6.0.44 (Jul 12, 2021)

  • Fixed issue that caused the ASIO engine to parse the MIDI events twice, causing some weird feedback in the audio.

New in OmniMIDI 14.6.0.31 (Jul 12, 2021)

  • Fixed race condition between the rendering threads and the stream health-check thread, that caused the driver to crash with an EXCEPTION_ACCESS_VIOLATION error when freeing the BASS libraries during the MIDI output closing process, when playing lots of notes (e.g. in Black MIDIs). The stream health-check thread will now wait for the renderin threads to close', before freeing up the BASS libraries.
  • Fixed crash when using BASSASIO, caused by a double-free of the device. The FreeUpBASSASIO() function in the driver now checks if the ASIO device has been started using BASS_ASIO_IsStarted().
  • Minor bug fixes.

New in OmniMIDI 14.6.0.27 (Jul 10, 2021)

  • Fixed initialization issues and crashes with XAudio2. It should work properly now. (microsoft msdn moment)

New in OmniMIDI 14.6.0.25 (Jul 9, 2021)

  • Changelog:
  • Enabled Control Flow Guard.
  • Increased minimum system requirements to SSE2-capable CPUs.
  • Removed debug chime.
  • Minor fixes.

New in OmniMIDI 14.6.0.17 (Jul 8, 2021)

  • Updated BASSMIDI to pre-release version 2.4.13 U20. This should finally fix the bad performance on Black MIDIs, which allowed me to remove the "optimized libraries" option from the configurator, while also bringing to the table the latest fixes when it comes to MIDI events parsing and SoundFonts decoding.
  • Reduced update rate of the stream health thread, which should increase the performance on BASS-related threads. The downside of this change is that live changes won't be applied instantly now, but it's not a big deal. The new update rate value is 333ms (from 30).
  • Fixed lots and lots of bugs in the code. The driver should feel more stable now.

New in OmniMIDI 14.6.0.0 (Jul 2, 2021)

  • Added speedhack system to the Windows Multimedia Wrapper (Configurator > Settings > Debug and legacy settings), for those Black MIDI no-lag freaks. You have to repatch the app, if it's been patched with an older version of the Windows Multimedia Wrapper.
  • Fixed numerous bugs caused by the awesome MSDN team and their terrible documentation about WinMM. I had to dig out an old Windows NT SDK PDF to be able to fix them.
  • The MIDI panic hotkey (Insert) will not reset the channel instruments, pitch bends and other related stuff anymore, and should only turn off all the currently playing notes. You can revert back to the old MIDI panic mode by holding Shift as you press Insert.
  • Minor bug fixes here and there.

New in OmniMIDI 14.5.3.0 (Jun 30, 2021)

  • Fixed weird compiler quirk introduced from version 14.5.0 that caused the driver to misbehave, especially when used through the OmniMapper. (It crashed Minecraft too, for some reason...?).

New in OmniMIDI 14.5.2.0 (Jun 28, 2021)

  • Updated BASSMIDI library to version 2.4.13.18.
  • Removed mask system.

New in OmniMIDI 14.5.1.0 (Jun 25, 2021)

  • Fixed issue that caused Windows Multimedia API apps to crash when loading the driver.

New in OmniMIDI 14.5.0.0 (Jun 24, 2021)

  • Fixed issue with the library loader that caused some MIDI applications to misbehave (e.g. Kiva).
  • Fixed issue that caused the XAudio2 to throw an error during startup. It was caused by an out of memory error in the driver's heap.

New in OmniMIDI 14.4.0.0 (Jun 23, 2021)

  • Updated BASS to version 2415 U59 and BASSMIDI to version 2413 U17
  • For Black MIDI users, you can still use the old libraries by using the "Load Black MIDI optimized libraries" option in the configurator's settings The latest libraries aren't suited for playback of multi-million MIDIs, I'm afraid
  • Added asynchronous mode support for Windows Audio Session API Enabling it could improve the latency but introduce some crackling too
  • Fixed issue that caused some driver errors to not display and instead crash the MIDI application
  • Optimized code of the audio thread and events processer
  • Minor bug fixes

New in OmniMIDI 14.3.0.0 (Jun 21, 2021)

  • The driver should not crash anymore when applying live changes that don't affect the size of the events buffer. Making changes to the size of the events buffer while events are being written to it will still lead to crashes, so always remember to pause the playback in the MIDI app and be careful!
  • Backported some features and optimizations from Shakra.

New in OmniMIDI 14.2.0.0 (Jun 21, 2021)

  • Fixed crash caused by a double free[] on XA/.WAV mode's sound buffer array.

New in OmniMIDI 14.1.0.0 (Jun 20, 2021)

  • Refined settings and code for XAudio 2.9 engine.
  • Minor bug fixes.

New in OmniMIDI 14.0.0.0 (Jun 19, 2021)

  • Added latency monitoring to the debug window, for those pros that want to know how much delay there is between the DAW and the actual sound. Useful for people who play instruments in live with the driver.
  • BASSWASAPI has been restored, which means that exclusive WASAPI support is available once again.
  • Changed behavior for incoming long messages. Instead of letting the app spam the driver with as many long messages as it wants, the driver will now spinlock and force the app to wait for the incoming long message to be parsed, before accepting any more. This should fix those glitches with apps such as vanBasco. Well-coded apps should not be affected by this behavior.
  • Fixed broken support on x86 machines.
  • Fixed issue that caused the setup to not spawn the required registry keys for the driver to work properly.
  • Fixed that annoying bug in the configurator that could make you lose your shared list.
  • Reduced crashes when changing settings in live. They might still happen, but it's normal. You should always restart your program after you change the advanced settings.
  • Renamed DirectX Audio to DirectSound 9.0L, to avoid confusions with the new and improved XAudio 2.9 engine! XAudio2 is back!!!
  • Reworked the ASIO control panel from scratch. It now gives way more info about the ASIO output.
  • The RivaTuner OSD has been removed. barely anyone actually made use of it.

New in OmniMIDI 13.8.15.0 (Jun 19, 2021)

  • Restored XAudio2 (XA Gaming) engine.

New in OmniMIDI 13.8.7.0 (Jun 6, 2021)

  • Fixed missing BASSWASAPI library on 32-bit installs of OmniMIDI.

New in OmniMIDI 13.8.5.0 (Jun 4, 2021)

  • Fixed issue that caused some registry values to not spawn on a clean install of the driver, causing the latter to crash on start.

New in OmniMIDI 13.8.4.0 (Jun 3, 2021)

  • Offloaded registry-related functions from the setup to the configurator. This should fix an issue that occurs when the driver is installed on a standard account while getting the privileges from another with admin permissions.

New in OmniMIDI 13.8.3.0 (May 31, 2021)

  • Fixed issue with shared list.

New in OmniMIDI 13.8.2.0 (Mar 11, 2021)

  • Now the driver, upon receiving a long message, will spinlock until the audio stream is ready. This is to prevent some apps from spamming the driver with long messages while ignoring the default return value (Which is MIDIERR_NOTREADY). This should fix some issues with badly coded apps such as VanBasco, that ignore the return value of the long messages call (midiOutLongMsg).
  • Minor bug fixes.

New in OmniMIDI 13.8.1.0 (Mar 8, 2021)

  • Fixed issue (#182). It was actually caused by WinMMWRP ignoring the setting in the configurator.
  • While the fix was as easy as making the patch read the configurator's setting (The original functions apparently worked fine, I thought they were broken oops), I actually decided to follow Khang's suggestion of importing the time* functions from Kernel32, instead of loading them from WinMM. This will only happen on Windows 8 and newer, since Windows 7 does not have those new functions in Kernel32. (This is also why Windows 8 and newer have two DLLs that mostly share the same functions, WinMM and WinMMBase)

New in OmniMIDI 13.8.0.0 (Feb 26, 2021)

  • Fixed issue (#181) that caused events to not be parsed properly.

New in OmniMIDI 13.7.0.0 (Feb 25, 2021)

  • Reworked ASIO control panel in the configurator. That should fix the BASS_ERROR_UNKNOWN error with Realtek ASIO, and the freeze when configuring FL Studio ASIO.
  • Minor fixes to the driver's code.
  • Dropped Update executable. I'll only provide the Setup from now on.

New in OmniMIDI 13.6.0.0 (Feb 23, 2021)

  • Fixed regression from OM13.5.3, that caused the configurator to crash on startup.
  • Removed RivaTuner OSD support. (From 13.5.2.0)
  • Fixed a code error that made the new WASAPI incompatible with Windows 8.1 or older. (From 13.5.2.0)
  • Fixed an issue that caused random notes to be played, after restarting the stream in normal playback mode. The issue did not occur in minimum playback mode. (From 13.5.2.0)
  • Fixed error that caused BASS to complain about tampering. (From 13.5.2.0)
  • Fixed error in the code that caused OM to load a BASSenc extension from the BASSASIO library. (From 13.5.1.0)
  • The driver will not crash anymore when rapidly changing settings that require a complete restart of the audio stream. (From 13.5.1.0)

New in OmniMIDI 13.5.1.0 Bugfix 1 (Feb 22, 2021)

  • Changelog:
  • Fixed error in the code that caused OM to load a BASSenc extension from the BASSASIO library.
  • The driver will not crash anymore when rapidly changing settings that require a complete restart of the audio stream.

New in OmniMIDI 13.5.1.0 (Feb 20, 2021)

  • Fixed error in the code that caused OM to load a BASSenc extension from the BASSASIO library.
  • The driver will not crash anymore when rapidly changing settings that require a complete restart of the audio stream.

New in OmniMIDI 13.5.0.0 (Feb 20, 2021)

  • Added workaround for apps that load the BASS libraries on boot-up. (E.g. Synthesia and Kiva MIDI Player)
  • Added option to disable the audio ramp-in (BASS_MIDI_FONT_NORAMPIN) to the configurator. (From 13.4.0.0)
  • Added latency info for all engines, in the debug window. (If you see a mismatch between the frames value in the debug window and the buffer size in the ASIO control panel, don't worry about it. BASSASIO automatically allocates a few more frames for audio monitoring. E.g. 64 samples + 48 for monitoring.) (From 13.4.0.0)
  • The debug window will now correctly report the correct KDMAPI status when using the Windows Multimedia Wrapper. (From 13.4.0.0)
  • Fixed bug with ASIO and new WASAPI that would make some notes get stuck and played every few seconds. (From 13.2.0.0)
  • Changed behavior of MIDI_IO_COOKED. It will not use dwUser's address for CookedPlayer anymore. The player will now be hosted inside OM's own working set. (From 13.2.0.0)
  • Updated the Windows Multimedia Wrapper to version 7.1, which should fix compatibility with apps that make use of callbacks and also fix a pesky issue with MIDI_IO_COOKED apps, such as GZDoom. (From 13.2.0.0)
  • Updated DirectX Audio engine. (From 13.1.0.0)
  • Restored BASSWASAPI. This means that WASAPI exclusive mode is back, together with some nifty features that could benefit Windows 10 users that both want low-latency playback and shared mode. If you don't like the new WASAPI implementation, you can always revert back to the old one by clicking "Use old WASAPI" button in the "Change output" window. (From 13.0.0.0)
  • Added a workaround for an issue in the MSVC libraries, that made FreeLibrary free up the libraries without zeroing the pointers. (From 13.0.0.0)

New in OmniMIDI 13.4.0.0 (Feb 15, 2021)

  • Added option to disable the audio ramp-in (BASS_MIDI_FONT_NORAMPIN) to the configurator.
  • Added latency info for all engines, in the debug window. (If you see a mismatch between the frames value in the debug window and the buffer size in the ASIO control panel, don't worry about it. BASSASIO automatically allocates a few more frames for audio monitoring. E.g. 64 samples + 48 for monitoring.)
  • The debug window will now correctly report the correct KDMAPI status when using the Windows Multimedia Wrapper.
  • Fixed bug with ASIO and new WASAPI that would make some notes get stuck and played every few seconds. (From 13.2.0.0)

New in OmniMIDI 6.0.57.4 (Nov 13, 2018)

  • The driver will now call LoadLibrary before LoadLibraryEx, to check if the BASS libraries have been loaded by another driver or by the app itself. If they're already present in memory, the driver will use them instead. GetModuleHandle doesn't increase the reference count, I forgot about that...

New in OmniMIDI 6.0.57.3 (Nov 13, 2018)

  • The driver will now call GetModuleHandle before LoadLibrary, to check if the BASS libraries have been loaded by another driver or by the app itself. If they're already present in memory, the driver will use them instead.
  • The driver will now free the BASS libraries (or decrement the reference count, if they've been loaded before by another driver or by the app), when either midiOutClose or TerminateKDMAPIStream are called.

New in OmniMIDI 6.0.57.2 (Nov 13, 2018)

  • Improved SoundFont loader code in the driver.

New in OmniMIDI 6.0.55.0 (Nov 7, 2018)

  • Major overhaul of the SoundFont loading system. The old SoundFont lists won't work anymore. You can try and import them through the configurator, but the presets/banks settings will not be loaded.
  • You can now edit the presets and banks without having to add the SoundFont to the list again. Just go to "Edit settings for this SoundFont".
  • You can now choose to use bank 127 for drumkits, when playing XG MIDIs. Just right-click on a SoundFont in the list, then go to "Edit settings for this SoundFont".
  • Removed mixer tools from the configurator, as they were buggy and weren't used by a whole lot of users.
  • Fixed issue that caused all the channels' volume to be set to 0, when installing OmniMIDI for the first time.

  • Enabled Control Flow Guard, to increase security against memory corruption vulnerabilities.

New in OmniMIDI 6.0.51.0 (Nov 2, 2018)

  • Fixed bad behavior on specific MIDI apps' behalf, where most of them wouldn't set the dwBytesRecorded value of a MIDIHDR packet, fooling the driver into thinking it received a 0 bytes long message. The driver will now parse the size of the event by itself. (vanBasco seems to do this as well.)

New in OmniMIDI 6.0.50.0 (Nov 1, 2018)

  • Improved debug log system. The messages will now be easier to understand for normal people too.

New in OmniMIDI 6.0.44.0 (Oct 18, 2018)

  • Fixed crashes when initializing or terminating the driver through KDMAPI twice.
  • Fixed issues with the Windows Multimedia Wrapper on some Windows XP installations. The patch would not work on Windows XP installs with the root partition set to a different letter than *C:*.

  • Replaced "OK" button with "Apply", in the ASIO device output selector window of the configurator. The output will not be set when switching them through the device list combobox, unless you specifically click "Apply".

New in OmniMIDI 6.0.33.0 (Oct 12, 2018)

  • Updated compatibility list for ASIO devices.
  • Fixed issue that caused the ASIO device selector window to crash, when trying to scan a device that refuses to be interrogated by BASSASIO.

  • Minor bug fixes.

New in OmniMIDI 6.0.3.0 (Aug 24, 2018)

  • Added synchronization between the event processer and the audio engine threads, to reduce the rendering time on weak systems. (It should not affect systems that were playing fine before this update)

New in OmniMIDI 5.0.3.29 (Apr 26, 2018)

  • I did it! I finally managed to get rid of the ReactOS-based WinMM patch! The wrapper performs BETTER too! You can safely patch your apps without having the fear of losing MIDI Input support.
  • Optimized runtime code together with Sono.

New in OmniMIDI 5.0.3.28 (Apr 24, 2018)

  • Changelog:
  • Update to the ReactOS patch, please repatch every program you have that makes use of it. (More info down below)
  • Added SendDirectLongData back to the driver.
  • ReactOS has a flawed implementation of the following WinMM functions:
  • midiOutPrepareHeader
  • midiOutUnprepareHeader
  • To fix the random crashes on, for example, MIDITrail, when using the patch, I had to literally remove the entire function, and replace it with a generic "return MMSYSERR_NOERROR;", and replace midiOutLongMsg with a function from the KSDirect API, which skips the first unprepared MIDIHDR pointer, and prepares the pointer by itself.
  • This workaround should probably not break GM/XG support on apps using the patch, but I won't make promises I can't keep!
  • P.S.: The wrapper is not affected.

New in OmniMIDI 5.0.3.26 (Apr 22, 2018)

  • Fixed regression that caused the slow down playback option to behave erratically.

  • Fixed compatibility with Windows Multimedia API patches.
  • Fixed some debug stuff.

New in OmniMIDI 4.0.5.8 (Jan 9, 2017)

  • Updated mixer window.
  • Since there's people who's dumb enough to try running the driver on OSes such as Windows ME, I got forced to add a version check to all the executables (Configurator, Mixer etc... Not needed for the driver, since Visual C++ 2013 isn't supported on Windows 2000 or older). All the executables will automatically exit.

New in OmniMIDI 4.0.5.7 (Dec 27, 2016)

  • Updated SoundFont info dialog.

  • Updated mixer window.
  • The long MODM data parser has been slimmed down.

New in OmniMIDI 4.0.4.7 (Nov 22, 2016)

  • SERIOUS: Fixed a bug in the driver register tool, which made it unable to register the driver on fresh Windows installations.
  • Added a "lock" to prevent the driver register tool from running on Windows XP.

New in OmniMIDI 4.0.4.6 (Nov 21, 2016)

  • Added support for relative paths to the configurator. (Explanation of this function down below)
  • Fixed a bug that made the configurator forget about the last directory visited by the user.
  • Fixed installer script, that made the mixer unavailable for 32-bit operating systems. (It was my fault, sorry)
  • Added useful links in the "Help" menu.
  • So, how do these relative paths work?
  • First of all, before I start explaining, I just want to thank an old user of the driver (Version 2.0 I think) that gave me the idea of adding support for relative paths.
  • Anyway, the final absolute path of relative paths is obtained by getting the path of the original .sflist/.txt file (The soundfont list) + the relative path inside it.
  • To move up by one folder, add ".." to the relative path, for two folders use "...." and so on.
  • Here, there's nothing more to explain, lol.

New in OmniMIDI 4.0.4.5 (Nov 21, 2016)

  • Cleaned source code of the configurator.
  • Added "Volume boost" function under "Additional settings > Advanced audio settings > Enable volume boost". It'll allow you to increase the volume beyond the 100% limit (Limited to 200%). It only works with XAudio.
  • Fixed some bugs in the configurator.

New in OmniMIDI 4.0.4.4 (Nov 13, 2016)

  • You can now get additional info about a soundfont by double-clicking it in the configurator. (One soundfont at the time)
  • Nothing else has been changed, if compared to version 4.0.4.3.

New in OmniMIDI 4.0.4.3 (Nov 12, 2016)

  • Added errors if the driver tries to load an invalid soundfont, or the stream fails to start.
  • Minor bug fixes.

New in OmniMIDI 4.0.4.2 (Nov 12, 2016)

  • Improved stability.
  • Added troubleshooter to the configurator. (Help > The driver isn't working anymore, help?)
  • Fixed a bug that could lead to Keppy's Synthesizer playing random notes after switching between playback modes (Slow down playback instead of skipping notes) or buffer systems (Use the old buffer system (No slowdowns)) during a crash part on a Black MIDI. More of a workaround than a fix.

New in OmniMIDI 4.0.4.1 (Nov 12, 2016)

  • BASS VST is not mandatory anymore. If Visual C++ 2010 is not installed, the driver will just warn the user, instead of closing the app.
  • Update to the soundfont lists system.
  • Now XAudio should handle notes better than DirectSound. The audio is stabler too.

New in OmniMIDI 4.0.4.0 (Nov 12, 2016)

  • Removed ALL fail-safes for Windows XP.
  • Optimized driver, now it should be faster with Black MIDIs.
  • Added "DLL override" function. You can use older/newer versions of the BASS libraries by dropping them in "%userprofile%Keppy's Synthesizerdlloverride(32or64bit)". Function available at "Additional settings > Troubleshooting > Open folder for DLL override".
  • Fixed minor bugs that were causing Keppy's Synthesizer not to be completely stable.
