Virtual MIDI Multitrack Recorder
Virtual MIDI Multitrack Recorder is a tiny and portable application that enables you to load, play and record Midi files. It contains just a few options.
Since installation is not required, you can save the app files in a custom location on the disk and simply click the executable to launch Virtual MIDI Multitrack Recorder.
Otherwise, you can copy it to a USB flash drive to directly run it on any PC with minimum effort. It doesn't create new entries in the Windows registry or Start menu, leaving the disk clean after removal.
The GUI looks slightly unusual and has some minor issues. For example, the button names have a very small font that cannot be increased in size.
The program's options are not that intuitive, but hovering the mouse cursor over a button shows a small description which should clear up everything.
Record, play and adjust Midi tracks
You can switch through different Midi devices for both the input and output, make a recording, play and stop the track, mute any channels (up to eight streams), scroll through multiple pages if necessary, loop a part of the track, enable or disable echo, adjust the sequencer tempo (in beats per minute), or quantize to tweak timing.
It's also possible to toggle the song and part modes, change the current part length, rename or edit the current part or song, modify the notes pitch of one or more tracks, merge tracks, erase one or more track or the whole part, and so on.
Evaluation and conclusion
The software application worked smoothly in our tests, without causing Windows to hang, crash or display error messages. It left a small footprint on system resources, using low CPU and RAM.
On the other hand, the fact that the interface is difficult to figure out (especially by less experienced users) makes Virtual MIDI Multitrack Recorder unattractive. We must also keep in mind that it hasn't been updated for a long time. Nevertheless, you can test it for yourself if you're looking for a MIDI sequencer, since it's free and open source.
