AudioMulch Changelog

What's new in AudioMulch 2.2.4

Jul 15, 2013
  • Fixed LoopPlayer bug where a muted LoopPlayer would sometimes start unmuted until the beginning of the next bar. This happened if a document was first played starting from anywhere other than the start of a bar (including when synced to MIDI or Network Sync).
  • Fixed extremely distorted audio when using over-unity floating point sound files in some contraptions (e.g. LoopPlayer).
  • Fixed LiveLooper crash when creating very short loops.
  • Fixed LiveLooper assertion failure crash "Assertion failed: (state_ == RECORDING)" if automation or MIDI control tried to clear a track while it was recording.
  • Fixed intermittent LiveLooper assertion failure crash "Assertion failed: (nextRecordTrack_ == 0)" when all tracks were empty.
  • Fixed AudioUnit hosting bug: sliders in the generic editor were not updating when parameters were changed using the custom editor or automation.
  • Fixed Network Chase Sync bug where tempo could sometimes become unstable (even after resetting sync by toggling enable audio off and on again).
  • Fixed rare crash in automation graphics rendering triggered by MIDI and/or Network Chase Sync bug(s) above.
  • Windows: fixed issue where no audio devices were listed if any ASIO device returned an error at startup. The MOTU "MOTU PCI Video ASIO" device was triggering this behavior when not connected and powered on.

New in AudioMulch 2.2.3 (Dec 14, 2012)

  • Fixed bug where clicking the LiveLooper Start button would sometimes not start recording, especially with high CPU load or when the audio driver buffer size was not set to a multiple of 64 samples.
  • Fixed crash: assertion failure "length >= fadeLengthSamples_" if you changed the sample rate in AudioMulch's Audio General settings while LiveLooper was recording.
  • Fixed bug where PulseComb hold would get permanently stuck on if you set the Hold Quantize Divisions multiplier to zero with Quantize Amount set to non-zero.
  • Fixed bug in PulseComb hold quantize behavior (present since version 2.1): Hold Quantize was taking priority over the Hold Period causing rapid holds when the hold duration should have been at least as long as Hold Period. To get the previous "buggy" behavior use a very short Hold Period.
  • Fixed bug in SDelay where delay times would not be displayed correctly (clamped to a maximum value of 32) when recalling presets that switched delay units from rhythmic units to milliseconds.
  • Display preset names in preset automation hover tooltips.
  • Fixed crash when recalling AudioMulch presets with DFX Transverb VST Plugin.

New in AudioMulch 2.2.2 (Oct 18, 2012)

  • Added 16 channel Matrix and Mixer contraptions.
  • Added right-click for Matrix contraption grid cells allowing Automate, Quick-map and direct access to parameters in the Parameter Control window for each grid cell.
  • Fixed bug where automation loop was sometimes skipped when the audio driver buffer size was not a multiple of 64 samples.
  • Fixed input/key meters on Limiter, NoiseGate and Compressor to reflect the input level after InputGain has been applied.
  • Fixed bug where patch was sometimes scrolled off screen when it was first opened.
  • Fixed bug in Flanger contraption that caused audio drop outs, extreme CPU load and crashes when using low Frequency Range settings when the audio interface sample rate was set to 96kHz or higher.
  • Added code to sanitize bad audio data coming from VST plugins, which could cause audio drop outs.

New in AudioMulch 2.2.1 (Aug 17, 2012)

  • Fixed crash: assertion failure "PortAudioStreamController Line 1118..." when using the Open Sound File dialog box to preview sound files when AudioMulch master audio was not enabled.
  • Fixed problems with level meters (SoundIn, SoundOut, Patcher activity indicators) flickering, freezing and/or not working under certain conditions.
  • Fixed bug where Bassline note name hover tooltips were sometimes not displayed when note cells displayed "...".

New in AudioMulch 2.2.0 (Jul 30, 2012)

  • New Features:
  • Added MIDI output contraptions (MidiOut1 - MidiOut8).
  • Added support for switching Metasurface snapshots via MIDI control.
  • Frequency parameters are now also displayed as musical pitches in parameter tool tips. They can also be edited as musical pitches using piano keyboard interface in the Set Value dialog box.
  • New SChorus stereo chorus contraption.
  • New header bar in contraption Preset window.
  • New Welcome Screen giving access to recent files and other options.
  • Enhancements:
  • Switched to internal 64 sample control rate with no lower limit on sound card buffer size. Results in higher stability with buffer size settings lower than 256 samples.
  • New timing engine for MIDI and network clock synchronization. Stable sync. Increased hardware compatibility.
  • Added “pattern mode” for MIDI sync generation for compatibility with Electribe and Nord Micro Modular step sequencers.
  • Added clock-synchronous period and phase mode to SSpat contraption. Synchronize spatialization paths to the global clock pulse.
  • Reworked and updated help file with a clear, modular, step-by-step tutorial format.
  • Added ability to clear automation points without deleting the time range. Using the DELETE key or selecting the Clear item in the Edit menu deletes the selected points. Using the Delete Time item in the Edit menu deletes the time range, which used to be the default behavior.
  • Removed limit on the number of presets per contraption.
  • Added Auto Hide button to contraption Preset Window.
  • Adjustable brightness and contrast of the user interface color scheme on the Appearance page of the Settings/Preferences Dialog Box.
  • Made MIDI and network sync offset settings have consistent meaning (positive values always make the slave later).
  • New sync offset settings for network sync.
  • The Metasurface parameters tree now supports multiple selection (using drag, SHIFT+click and CTRL+click) and enabling/disabling selected items. Added "Enable Selected Parameters" and "Disable Selected parameters" context menu items.
  • Unified handling of drag-and-drop behavior between Metasurface snapshots, contraption Presets, Document Switcher document entries, File Player and File Recorder. These should now all behave consistently.
  • Windows Vista and 7: Added Settings > Audio Driver > "Disable Desktop Window Manager MMCSS scheduling" option. May reduce graphics card related audio glitching on some systems.
  • Reworked generic plugin editor grids for VST and AU plugins.
  • The interpretation of MIDI Control Change and Program Change messages has been updated to be more conformant with the MIDI specification when controlling presets and Metasurface snapshots. By default the first (0th) MIDI value now maps to the first (1st) preset/snapshot. There’s also an option to change the offset.
  • Use AudioMulch’s Open Sound File dialog box when locating missing sound files to allow previewing soundfiles.
  • Bug Fixes:
  • Fixed crash in Patcher if the right mouse button was clicked while dragging a patch cord.
  • Fixed rare automation recording corruption and crash "Assertion failure AMTimelineEditWidget.cpp line 407" while zooming automation.
  • Fixed bug where automation recording could write additional points after transport was stopped if you pressed the Stop button before toggling the Record button.
  • Fixed crash when editing Drums contraption events when an automated preset/pattern change occurred.
  • Fixed bug where SouthPole envelopes would continuously re-trigger if Automation stopped but was at a pattern trigger location (i.e. time 0).
  • Fixed issues with VST plugin property values not being synchronized after recalling or loading a VST program or program bank. This should allow all VST plugins (e.g. u-he Zebra and NI Reaktor) to work correctly with the Metasurface.
  • Keep VST parameter name displays in sync with plugins that dynamically change parameter names (e.g. Reaktor, FXpansion Guru).
  • Fixed bug in VST generic property editor where sliders didn't match property values after switching from custom to generic editor.
  • Windows: Fixed issue with Reaktor VST plugin Delete key presses not going to plugin but instead deleting items in the Patcher.
  • Parameter knobs and sliders now respond to Metasurface and MIDI control even when Audio is not enabled.
  • Fixed bug where Chase MIDI and Network sync settings were always unchecked/reset whenever Settings/Preferences Dialog Box was displayed.
  • Fixed zipper noise when moving SDelay Feedback parameter and the Wet/Dry parameters on SDelay, FrequencyShifter, DLGranulator, NastyReverb, Flanger, Nebuliser.
  • Fixed potential crash when MIDI messages were received while disabling audio.
  • Fixed bug: AuxOut contraptions not showing inlets when creating by drag and drop.
  • Fixed micro-jittering of property values during Metasurface interpolation if all snapshots hold the same value.
  • Reduced CPU load when interpolating Metasurface snapshots if there were many parameters with no value changes.
  • Fixed crash: shift+clicking on a contraption or connection in the Patcher Pane when it was the only selected contraption or connection and then deleting it, would crash.
  • Windows: Fixed bug in .amh document save and load routines which would sometimes cause values to be lost on systems which used a decimal comma "," instead of a decimal point ".".
  • Fixed issue with SSpat glitching/clicking when using a large "Scale" value, and also when using audio buffer sizes < 256 samples.
  • Fixed bug that would cause distortion/zipper noise in Compressor and NoiseGate when sample rate was greater than 48k.
  • Improved number display in number edit boxes such as those used to specify the tempo and the loop length in LoopPlayer. Should no longer display a long string of 0.9999999999999999 or 0.0000000000001 e.g. when incrementing and decrementing values using the mouse or the arrow keys.
  • Fixed problems with long strings of decimal places in Tempo number edit box after clock-syncing tempo.
  • Optimized speed of display/rendering for sliders and knobs.
  • Fixed "green fur" display issue on combo boxes in contraption editors, when hovering mouse over combo box and there are overlapping contraption editors with a pattern editor behind.
  • Fixed bug: sample rates not updating in Settings/Preferences dialog box latency labels (e.g. Windows Multimedia) after changing sample rate.
  • Reflect the names of renamed input/output contraptions in level meters and settings. Display I/O contraption name text as well as contraption type name in level meters, patcher tool tips, settings window audio device table tool tips.
  • Windows: Fixed Main Window title blinking "*" and document name changes during opening or switching documents.
  • Fixed layout of SouthPole LFO2 tab: when switching between SouthPole LFO 1 and LFO 2 the controls were not aligned.

New in AudioMulch 2.1.2 (Dec 9, 2011)

  • Fixed bug where contraption preset window would spontaneously disappear when one of the contraption editor button tooltips displayed and then hid.
  • Fixed bug in audio settings where setting devices to None was not remembered after restarting AudioMulch. Instead, the default device and all channels would be selected at next startup.
  • Fixed bug/crash assertion failure "DRAG_STATE_NONE" when trying to drag 5Combs contraption editor while pitch selection window was visible.
  • Fixed bug where selection of AIFF files was not possible during the "locate missing sound files" process.
  • Improved scroll wheel behavior in properties pane. Scroll wheel no longer gets stuck on individual controls while scrolling the whole view. Scroll wheel now only acts on number editors when they already have input focus. Scroll wheel never acts on combo boxes and FilePlayer/Recorder location bars.
  • Mac: improved stability of MIDI clock sync generation output. It was stuttering or unreliable with some MIDI devices.
  • Fixed intermittent bug on Windows where evaluation period was indicated as expired immediately after first installation.

New in AudioMulch 2.1.1 (Sep 7, 2010)

  • Fixed bug where documents that used a missing VST plugin would load with an arbitrary placeholder VST rather than warning that the plugin was missing.
  • Fixed bug where a LoopPlayer with an automation mute change at the beginning of bar 1 wouldn't recognise the mute change until bar 2 when playing from start or exporting.
  • Fixed bug in Arpeggiator where selecting only one note in Random and UpDown Direction mode would play more than one note. Made Random Direction mode more uniformly random.
  • Fixed bug where changing Settings/Preferences for MIDI sync offsets or MIDI generate sync device would cause MIDI control and chase sync to stop functioning until you restarted AudioMulch, disabled/reenabled these functions, or selected a different MIDI device.
  • Fixed crash if you quit while a contraption preset window was visible.
  • Windows: Fixed bug where View > Windows Volume Control menu item didn't work on Windows Vista and Windows 7
  • Fixed bug where opening a document and saving it with Save As... would not add the original document to the Reopen/Recent Items menu.
  • Fixed Play and Record buttons on File Players and Recorders so that you can right-click and choose Automate, Quick-map MIDI etc, even when the buttons are disabled because no file is selected in the contraption.
  • Fixed bug where the patcher contraption input/output info tooltip was not hidden correctly after connecting a patch cord. Tooltips are now updated while connecting/reconnecting patch cords.
  • Fixed bug in pattern editors (Drums, Bassline, SouthPole, Arpeggiator) where you couldn't easily scroll or zoom past bar 32 unless there were pattern triggers present near the end of the pattern -- the sequence length was ignored.
  • Fixed bug in Bassline where you couldn't always see the note name cell text if you were zoomed in too far.
  • Fixed bug where automation lines weren't always highlighted correctly when you hovered the mouse cursor over them (e.g. minimum line for Range parameters)
  • Streamlined layout of Parameter Control window
  • Prevent multi-file Player and Recorder contraption editors from being resized beyond the maximum useful height.
  • Changed increments on MIDI sync offset number boxes to increment by +/- 1ms (previously 200ms)

  • Added right-click Create Contraption and Help context menu items to new contraptions palette.
  • Added contraption editor context menu items for Close/Close all/Close all but this; added shift-click close button to close all.
  • Included property names in contraption editor knob and slider popup value tool tips.
  • Added Recall button to contraption presets grid.
  • Added Close Sound File button to LoopPlayer and BubbleBlower. Added ability to close sound files in Drums with Ctrl-click or Right-click > Close Sound File.
  • Added HH:MM:SS.sss elapsed / total displays to file players and recorders (replaces old display of duration in seconds).
  • Beats are now divided into 48 subdivisions (previously 12), to allow finer-grained grid snapping in Drums and Automation.
  • Added 64th and 64th-triplets to the list of standard rhythmic units.
  • Added 10 channel variant of multi-file players and recorders.
  • Allowed use of enter key (Ctrl-Enter) to create new Metasurface snapshots after typing a snapshot name.

  • VST generic plugin editor now displays up to the first 8 parameters by default instead of the first 3.
  • The preset pop-up for a contraption now scrolls when it is displayed so that currently selected contraption preset is visible.
  • Windows: Audio, midi and network devices are disabled/enabled on APM suspend/resume (i.e. the audio device closes when the computer goes to sleep).
  • Bug Fixes:
  • Fixed SDelay to update the delay time when the tempo changes when using tempo-synced delays.
  • Fixed bug where WAV and AIFF sound files were saved with incorrect internal size fields. This caused warnings when opening the files in some audio editors (e.g. Goldwave).
  • Fixed bug where SDelay delay time combo boxes didn't have the correct range set when you first opened the editor (was possible to set delay time in semiquavers beyond 32, for example).
  • Fixed bug where locating a missing soundfile in SoundIn, FilePlayer, SoundOut or FileRecorder wouldn't cause the contraption play button to be enabled (it would stay disabled and you couldn't click it).
  • Fixed loading of track status indicator icons in CanonLooper (previously they weren't displaying).
  • Improved handling of display range and zooming in Drums contraption pattern editor.
  • Fixed bug where timeline maximum zoom level was dependent on zoom level when window was resized.
  • Fixed bug in BeatProcess.amh where thumb could go negative.
  • Fixed help file not displaying for AuxIn and AuxOut above 7.

  • Removed the ability to automate Clock.Start (because it didn't make sense)
  • Disabled slide-out of Patcher new contraptions palette while patcher pop-up menu is visible.
  • Fixed bug where altering values in a Drums contraption while the contraption changed preset in automation playback would crash with the following error: "Invalid parameter passed to (null), (null), (null) line 0".
  • Fixed input labels on RingAM contraption: they used to say Left and Right when they should have said Carrier and External Modulator. Similar fixes to M2Bus, M2Mixer, P2Mixer, MNoiseGate etc.
  • Fixed isAbsolute() assertion failure crash when loading old documents which had been saved in the root of a drive (e.g. D:).
  • Fixed bug where VST parameter name cleaning would crash if parameter name only contained spaces (caused a Starplugs plugin to crash).
  • Mac: fixed bug where plugins protected by PACE iLok copy protection would hang and you couldn't click through their authorisation screen.
  • Cosmetic Refinements:
  • Positioned patcher output port info tooltips below ports so they don't obscure the contraption.

New in AudioMulch 2.0.4 (May 7, 2010)

  • Fixed hung notes and/or plugin crashes when using VSTi plugins controlled by MIDI. The bug occurred when MIDI data is received on multiple MIDI channels simultaneously and the plugin Receive Channel is set to a single channel (i.e. not "None" or "All").
  • Fixed intermittent crash when displaying a VST generic editor while audio is running: "assertion failed: slider != 0"
  • Fixed rare crash while previewing a sound file in the open sound file dialog: "assertion failed: lastAlloc_->Blocksize()==size"

New in AudioMulch 2.0.3 (Nov 3, 2009)

  • Fixed crash bug when loading AudioMulch 1.0 documents that contain Drums contraptions with MIDI-controlled or automated channel volumes.
  • Fixed bug where you wouldn't be prompted to save changes before closing the document if the only change you made was renaming contraptions.
  • Fixed bug where VSTs with a MIDI output and no audio output would receive incoming MIDI messages twice.
  • Windows: Fixed "cannot load sqlite database driver!" error while trying to access the help file on some machines.
  • Fixed bug where LoopPlayer, FilePlayer, etc. would sometimes not show the question-mark icon when AudioMulch could not find the sound file.
  • Fixed glitch where the sound file name in LoopPlayer, FilePlayer would sometimes be abbreviated with "..." even when there was space for a longer name.
  • Fixed bug where the Notes window was given focus after loading a document, so you couldn't immediately use transport key-shortcuts (because they would type in the Notes window instead).
  • Fixed bug where you couldn't close the Set Value dialog box by pressing the Enter key.
  • Fixed bug where triggering Clock.GoToStart via MIDI didn't update the transport position on the GUI if the clock was stopped.
  • Fixed document switcher to scroll back to top when a new document set is Opened, on New, and on Clear All.
  • Fixed patcher display glitch where some ports would remain incorrectly colored after reconnecting patch cords.

New in AudioMulch 2.0.1 (Jun 30, 2009)

  • Fixed crash in patcher when ctrl-drag-duplicating a contraption and immediately docking it into another contraption without releasing the mouse. Crash only occurred when Show Contraption Input/Output Info was enabled and mouse was released over one of the new contraption's input or output ports.
  • Fixed bug where Export to Sound File function would not terminate (it exported until the disk was full) if an automated clock stop marker was encountered while prerolling or exporting.
  • Fixed bug where pressing the Return (Enter) key when editing parameter values in number editors and Metasurface snapshot and contraption preset names would cause the clock to stop and go to start rather than completing text editing. Also changed number editor behavior so Space bar starts/stops the clock even when a number editor has focus.
  • Fixed bug where typing numbers into a number edit in some places (e.g. Parameter Control window) would enter the numbers in reverse order (right-to-left).
  • Fixed bugs where tempo automation always defaulted to 120 bpm and did not pick up current tempo when first enabled, nor would it record tempo changes from the GUI (it would record tempo changes from MIDI).
  • Fixed bug where choosing Change Color... for a Metasurface snapshot, then pressing Cancel in the Select Color dialog box always made the snapshot black.
  • Fixed bug where SoundIn Sync mode didn't function correctly in all File Recorder contraptions.
  • Fixed bug where MIDI mapping curve editor in the Parameter Control dialog would not allow insertion of new breakpoints on vertical line segments including at the left and right edges of the editor.
  • Fixed bug where automation scroll bar would not take loop end and selection end location into account so you couldn't drag the scroll bar thumb to the loop end and had to use the arrow buttons.
  • Mac: added additional audio i/o buffer size settings to the Audio Driver page of the Preferences dialog box (previously this setting was fixed at 256 samples.)
  • Mac: fixed bug where selecting sample rates used sample-rate-conversion instead of switching the hardware sample rate. This should resolve problems with glitches at low CPU loads and high sample rates e.g. 96kHz.
  • Mac: fixed bug where non-hardware "virtual" MIDI devices were not available (e.g. from Numerology and OSCulator).
  • Mac: fixed issues with number edit boxes being too tall (eg in Parameter Control window).
  • Mac: removed close button on Preferences dialog box window header to avoid confusion with OK vs. Cancel behavior.
  • Mac: fixed graphical glitches around the edges of SSpat and Shaper contraption editors.
  • Mac: added command-shift-f5 keyboard shortcut to refresh VST Plugins list.
  • Mac: changed VST enumeration algorithm to only load bundles with .vst extension.
  • Windows: fixed bug where Select Sound File dialog for recording and export did not display on some Windows XP systems.
  • Windows: fixed bug where Reaper's ReaRoute ASIO driver did not appear in the device list.
  • Windows: fixed VST GUI window creation bug which resolves issues with Bidule VST freezing/crashing at startup or during use.
  • Windows: fixed implementation of VST audioMasterPinConnected which was causing "assertion failed currentOps_!=0" with some plugins including TinyGod Pegger 3.
  • Windows: fixed handling of VST GUIs which change their size using the non-standard method of directly resizing their parent (e.g. Schwa Olga).
  • Added Rename menu item to Metasurface snapshots context menu.
  • Fixed Export to Sound File dialog box to remember the preroll duration setting from the last time it was displayed.
  • Fixed bug where piano keyboard pitch selection popup window didn't show the correct note name when it was displayed (always showed C#8).
  • Fixed broken links to Crossfader and Frosscader help pages.

New in AudioMulch 2.0 (Jun 19, 2009)
