The GENaJam device provides real-time MIDI control over all YM2612 parameters:

Per-Channel Controls:

- Algorithm selection (8 different operator configurations)

- Feedback amount for operator self-modulation

- Stereo panning (left/right/center)

Per-Operator Controls (4 operators × 6 channels = 24 total):

- Frequency multipliers for harmonic ratios

- Detune for fine frequency adjustments

- Attack/Decay/Sustain/Release rates for envelope shaping

- Sustain levels for envelope dynamics

- Output levels for operator volume balance

- Rate scaling for pitch-dependent envelope behavior

- Amplitude modulation sensitivity

- SSG-EG (Software Sound Generator Envelope Generator) modes

Global Controls:

- LFO speed and depth for vibrato/tremolo effects

- Channel assignment for polyphonic vs monophonic operation

- MIDI channel routing and velocity response

Musical Capabilities:

The YM2612 can produce a wide range of sounds:

- Bass synthesizers with rich harmonic content

- Lead synthesizers with complex modulation

- Pad sounds with evolving textures

- Percussive sounds using fast envelopes

- Bell and metallic tones through specific algorithms

- Organ-like sustained tones

The GENaJam + GenMDM essentially turns the Sega Genesis / Mega Drive into a fully controllable, real-time FM synthesizer that can be played from any MIDI controller or DAW, making the classic Genesis sound accessible for modern music production.

Ready to use out of the box. (Supply your own 3.5" TRS Cable to your instrument)
