    PreenFM is a set of electronic components and C++ files that, when put together become a Frequency Modulation sound module. (Its FM synthesis is not at all based on any Yamaha FM chip.)

    The PreenFM with firmware 2.00, main features include :

    . 9 different FM alogorithms with up to 6 operators
    Each operator includes one oscillator and one ADSR enveloppe
    Oscillator : 7 waveforms (4 sin variation + noise + square + sawtooth),
    linked to keyb freq or fix, fine tune

    . Up to 8 voice polyphony with 3 operators FM algoriyhm
    up to 6 voice polyphony with 4 operators FM algoriyhm
    and up to 4 with 6 operators FM algoriyhm.

    . Glide available when voice set to 1

    6 LFOs routable in the modulation matrix
    . 3 standard LFOs (5 waveforms (sin, saw, ramp, square, random),
    frequency in Hz or synced to external MidiClock (/16, /8, /4, /2, *1, *2, *4, *4, *8)
    ramp up to 4 seconds, reset on new note).
    . 1 Env type LFO
    . 2 Step sequencers (16 steps) - BPM from 10 to 240 or synced to MidiClock (/4, /2, *1, *2, *4)

    . 12 rows modulation matrix - 15 different sources and 42 destinations

    . Gate effect (kind of) available in matrix destination - step sequencer routable

    . 4 user banks of 128 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 thru allow to insert the PreenFM in a MidiChain.
    PreenFM Midi channel selectable
    . Can send CC to external gear from modulation amtrix

    . 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

    . 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

    . A PreenVST to control your PreenFM sound module from within your sequencer
    (currently exists for OSX and win32/64 VST versions)
