This is a bare PCB for the open-source preenFM2 polyphonic FM synthesizer. Capable of importing DX7 sysex banks, this is the ultimate DIY FM polysynth!
A mostly through-hole design makes this an easy assembly for all levels of DIY experience.
NOTE: While the preenFM2 PCB board is completely through-hole, the preenF405 MCU Board (a separate PCB for the microcontroller) requires some surface mount components. Alternatively, you can use a CERB40 MCU board with an additional USB cable.
4 independent instruments
up to 14 voices of polyphony (8 if you use 6 op algorithms)
can import DX7 sysex banks
Midi over USB
USB drive: huge preset banks: 64128 presets, 8128 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.
Comprehensive user interface and associated to a 4×20 characters display for easy preset edition
arpeggiator (Mutable-Instruments opensource algorithm).
1 effect Slot (LP, HP, Bass boost, Band Pass, crusher)
1 gate effect
4 rapid access performance parameters
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
7 low frequency modulators (3 LFOs, 2 envelopes, 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.
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.
