The René music synthesizer module is a a powerful three-dimensional prism of composition. It is the world's only 3D Cartesian Music Sequencer. Named for the French philosopher & mathematician René Descartes, it uses the Cartesian coordinate system to unlock the analog step sequencer from the shackles of linearity. The original René was a one-channel, two-dimensional Cartesian sequencer with limited memory, this new René is a three-channel, three-dimensional Cartesian sequencer with memory for up to 64 complete STATEs. Considering the multiple channels and FUN programming options per multiple axis, René has become an n-dimensional matrix or tesseract of synthesizer sequencing.
