Modulaire Maritime Phosgène — Cheat Sheet

What it is

Phosgène is a 2hp digital wavetable / FM oscillator with: - 60 wavetables total - 2 banks of 30 waves - Two parallel sound engines / outputs - Wavetable / waveshaping output - FM output - Shared controls for wave/folding/FM behavior - V/Oct tracking over 8 octaves - Internal setting memory for: - bank - wave - octave

Quick start

Patch V/OCT from your sequencer/keyboard.
Take audio from either:
WAVE for wavetable/waveshaped tones
FM for darker, tighter FM tones
Set COARSE to tune.
Use WAVE SEL CV/input and front-panel selection to choose the waveform.
Use FM MOD CV to push deeper modulation / timbral movement.
Use the OCTAVE switch to shift pitch up/down by octaves.
Use OCT DISPLACE if the wavetable range is too bright/high and you want more usable low-end.

Sound / behavior notes

Waveshaping / folding is available on the wavetable side.
FM uses a 100 Hz frequency base, producing a more restrained spectrum, good for:
tight FM basses
dark/deep modulation tones
FM and wavetable functions share controls, but the FM engine has its own output.
The module has an intentionally lower-resolution digital character (11-bit), so some aliasing / grit is part of the sound.
Octave Displace applies only to the wavetable side, not the FM side.

Controls

Knobs / panel controls

COARSE
Main coarse tuning control.

Switches / buttons

OCTAVE
Octave up/down switching.
Changes pitch in 1 octave steps.
BANK 1 / BANK 2
Selects which set of 30 wavetables is active.
OCT DISPLACE
Shifts the wavetable octave range lower.
Useful to:
- keep brighter/folded tables in a more usable range
- reduce excessively high/alias-prone behavior
- extend low-end on wavetable tones
Does not affect FM output/range.

Practical patch ideas

1. Basic oscillator voice

V/OCT from sequencer
WAVE to filter/VCA
Use COARSE for tuning
Select bank/wave to taste

2. Dark digital bass

Patch from FM output
Sequence with V/OCT
Use lower octave settings
Add envelope/VCA after output

3. Animated wavetable line

Send slow CV/LFO to WAVE SEL
Listen from WAVE
Use OCT DISPLACE if the upper range gets too brittle

4. Parallel dual-tone patch

Patch WAVE and FM to separate mixer channels
Sequence both from same V/OCT
Blend bright wavetable edge with darker FM weight

Memory

Phosgène saves the last used: - Bank - Wave - Octave

These settings are restored on power-up.

Caveats

The source page is descriptive rather than a full technical manual.
Exact jack voltage ranges, output levels, power draw, and calibration details are not provided in the supplied manual page.
