MidiVolve is a Max For Live arpeggiator, riff generator, and pattern sequencer that automatically creates evolving MIDI patterns, in turn creating new riffs, melodies, and grooves. The plugin transforms recorded or imported MIDI clips by morphing various per-note parameters (velocity, pitch, duration, and two freely mappable lanes), with the user given control of the chance and degree of randomization applied to each.
The package also includes a library of 11 unique instruments (with 60 presets) and 8 audio effects racks that were developed in conjunction with Johannesburg musician and samplist Behr. The instrument racks are based on a 1GB library of sampled African instrumentation and sounds from Coldcut's archive.
