The PreenFM2 brings the old FM synthesis in a small open-source modern DIY box

4 independent instruments (four time multitimbal). Each of them has:

• Powerful arpeggiator (Mutable-Instruments opensource algorithm).
• 1 effect Slot (LP, HP, Bass boost, Band Pass, crusher)
• 1 gate effect
• 4 rapid access performance parameters
• The 4 instruments can be saved all at the same time in combo presets.
• Each instrument has its own modifiable midi channel. They can share the same for FAT quadruple timbres notes.
• Modifiable number of allocated voices… Between 1 and 14.
• 28 FM algorithms from 3 to 6 operators

Up to 14 voices of polyphony (8 if you use 6 op algorithms). Each voices has:

• 7 low frequency modulators (3 LFOs, 2 enveloppes, 2 step sequencers).
• 12 rows matrix : 16 sources, 32 destination (LP, HP, gate, stereo, MI, attack…)
• Arpeggiator, LFOs and step sequencers synchronizable on external midi clock or internal clock.

Operator features:

• 7 builtin waveforms + 6 user waveforms read from the usb drive.
• Stereo panning (at the carrier operator level)
• 8 envelope parameters per operator (DX7 like)

Direct Scala scale file loading for microtonality. Up to 128 Scala scales selectable from the preenfm2. Modular Randomizer

USB all the way: * Midi over USB * USB drive: huge preset banks: 64*128 presets, 8*128 combos, 256*32 DX7 presets. * the USB drive holds your preset banks, you scala scale files, your user waveform files. * Easy firmware upload and flash. * USB powered
