The Tetra Midi Analog Performance Sequencer (TetraMAPS) vastly improves on the first 'MAPS' core design. Expect to use a sequencer that is more versatile and intuitive. TetraMAPS gives you infinite virtual tracks, modulations and multiple, real-time versions of each sequence, polyphonic sequencing, four channels of CV output and computer network Open Sound Control.
Build your own custom sequencer iPhone/iPad interface using Hexler's TouchOSC or Liine's Lemur editors.
