Up to 4 voice polyphony with 3 operators FM algoriyhm Up to 3 voice polyphony with 4 operators FM algoriyhm and up to 2 with 6 operators FM algoriyhm. . Glide available when voice set to 1 . 3 standard LFOs (4 waveforms (saw, ramp, square, random), frequency in Hz, ramp up to 4 seconds, reset on new note). . 1 Enveloppe type LFO . 2 Step sequencers LFO (16 steps) : independant gate value and BPM. Their scale allow controlling pitch in semitones. . 12 rows modulation matrix - 14 different sources and 33 destinations. . 4 banks of 128 user presets . System exclusive to exchange patches and banks with a computer . Midi control : 44 control input/output control changes linked to parameters Nrpn : input/ouput of all paremeters Midi channel selectable : Midi for other channges can be forwarded to plug several PreenFM in serial . Large readable 4x20 LCD . Friendly surface controle : You always clearly see on the screen what you're currently editing . Sampling rate : 32768 Hz (Makes integer division faster ;-). Pseudo 11 bits. 1024 Hz for LFO and modulation matrix . Test note : play note without keyboard. Pitch and velocity editable. . 6th order butterworth analog filter to convert the 1 bit output into a nice waveform . Transparent case that allows you to see every day your nice work -------------------------------------------- Xavier
