MORPHEUS // MANUAL

8-Track ReBirth Groovebox & Matrix Pattern Sequencer for M-VAVE FM-1

1. Introduction

MORPHEUS transforms the ultra-portable M-VAVE FM-1 hardware groovebox into a standalone 8-track ReBirth-style groovebox and matrix pattern sequencer workstation.

It combines a 240×240 pixel high-contrast LCD matrix grid with a high-performance audio DSP engine. It integrates circuit-modeled TR-808 and TR-909 drum machines with a dedicated 12-lane Drum Matrix (ACC, CH, OH, CY, CB, CP, RS, HT, MT, LT, SD, BD), dual TB-303 acid synths with non-linear diode ladder resonance, Devilfish envelope expansion, and RAT-style distortion, an Amen breakbeat loop slicer, a 2-operator FM lead synth, a sub-bass synth, and independent MIDI channel output for every track (CH 1–16).

STEP 4

Sculpting Acid Magic: Portamento Slides & Accents

The soul of 303 acid music comes from two physical behaviors: note ties (triggering smooth 60ms analog pitch glides without envelope re-triggers) and velocity accents (exponentially opening cutoff and sharpening decay).

Action / Control	Screen Display	Functional Outcome
SELECT (Scrub to Step 3)	`STEP: 3 (D#2)`	Targets the desired step for modification.
KNOB 2 (Turn clockwise)	`TIE: ON [→]`	Enables portamento slide into step 4 without re-striking the amplitude envelope.
HOLD EDIT + KNOB 1	`VELOCITY: 127 [ACCENT]`	Boosts note velocity above 105, engaging accent overdrive and filter snap.

Automating Filter Sweeps with the Modulation Curve Track

MORPHEUS provides a dedicated per-step automation curve track alongside every pattern. You can draw automated filter sweeps (MIDI CC 74) that cycle continuously with hands-free precision.

Action / Control	Screen Display	Functional Outcome
ENV	`CURVE VIEW (CC 74)`	Toggles display from note piano roll to the per-step modulation curve editor.
SELECT + KNOB 3	`STEP CC: 20 → 118`	Sets modulation curve values step-by-step to craft a rising and falling filter sweep.

4. 4-Track Sequencer Engine

MORPHEUS functions like a rack of 4 synced pattern sequencer units operating simultaneously:

Total Memory: 4 Tracks × 4 Banks (A–D) × 8 Patterns = 128 patterns saved into flash memory.
Polyrhythmic Track Lengths: Each track can run independent sequence lengths from 1 to 32 steps (e.g., T1 running 16 steps in 4/4 while T2 runs 7 steps for polymetric grooves).
Step Resolutions: Selectable per track: 1/2, 1/4, 1/8, 1/16, 1/32, and triplets (1/4T, 1/8T, 1/16T).
Shuffle / Swing: Adjustable from 0% (straight) to 75% for groovy acid shuffles.
Independent MIDI Routing:
- Track 1: MIDI Channel 1 (Default: 303 Bass)
- Track 2: MIDI Channel 2 (Default: Synth Lead)
- Track 3: MIDI Channel 3 (Default: Arpeggiator)
- Track 4: MIDI Channel 10 (Default: Drum Machine Triggers)

5. Step Recording & Editing

Step Recording:

Press REC (LED illuminates).
Press any of the 27 silicone keys. The note is assigned to the active step with default gate velocity (115), and the cursor automatically advances to the next step.
To enter a rest, turn the SELECT knob forward without pressing a key.
To tie a note into the next step (for an acid slide), turn KNOB 2 clockwise.
Press REC again to exit recording.

Drum Step Programming (16 White Keys):

On drum tracks (TR-808 and TR-909), the 16 white silicone keys function identically to the 16 step buttons on classic Roland rhythm composers.
Tapping a white key immediately toggles the trigger on or off for the active drum lane at that step (Steps 1–16 on Page 1, or Steps 17–32 on Page 2).
Black keys are reserved for pitched synth modes and do not trigger drum steps.
The integrated keyboard LEDs illuminate to display all active triggers for the selected drum lane, and track the running playhead in real time. Any key pressed also lights up instantly.

Manual Grid Editing:

Scrub through steps with the SELECT encoder.
Adjust pitch with KNOB 1.
Adjust gate length / tie with KNOB 2.
Adjust modulation curve value with KNOB 3.

Pattern Tools & Multi-Level Undo / Redo:

To protect your sequences, destructive actions like Randomize and Clear are safeguarded inside the Pattern Tools menu:

Opening Pattern Tools: Tap FX. The 240×240 screen displays the Tools overlay (Undo, Redo, Shift Left/Right, Transpose ±1, Alter, Randomize, Clear).
Navigating Tools: Turn the SELECT knob (or click directly on screen). Press HOME to execute the selected tool. Tap FX again to cancel with zero changes.
Multi-Level Undo: Hold EDIT and press HOME (or press Ctrl+Z / Cmd+Z in browser). Every note entry, velocity change, transpose, or randomize operation can be reverted immediately.
Multi-Level Redo: Hold EDIT and press SAVE (or press Ctrl+Y / Cmd+Shift+Z).
Intentional Randomize Shortcut: Hold EDIT and press FX to generate a fresh minor pentatonic pattern with automatic Undo snapshot creation.

6. Built-in Multi-Engine Sound Generator

Press LFO (or Sound) on the hardware to cycle through the internal audio engines:

1. 303 Acid Bass Engine:

A non-linear model of the classic transistor bass synthesizer:

Resonant Diode Ladder Filter: Saturated self-oscillating 4-pole low-pass filter with asymmetric feedback distortion.
Portamento Slide on Tied Steps: When two adjacent steps are tied, the pitch smoothly glides at 60 ms without re-triggering the envelope attack.
Accent Overdrive: Velocities ≥ 105 engage accent boost, opening the filter cutoff exponentially and shortening decay for punchy resonant squelch.

2. Subtractive Analog Lead Engine:

Dual-oscillator subtractive engine with pulse-width modulation and an analog 24 dB/oct low-pass filter for leads, pads, and chord stabs.

3. 2-Operator FM Engine:

Dynamic phase-modulation engine with carrier-modulator feedback for bells, metallic plucks, and FM bass.

4. MUTE Mode:

Completely disables internal audio DSP for 0% CPU consumption and zero latency when using MORPHEUS exclusively as a hardware MIDI sequencer for external synthesizers.

7. Saving, Import & Export

Press SAVE on the FM-1 to write all tracks and patterns into the on-board flash storage sector. The firmware automatically reloads your patterns on power-up.

In the web emulator, click Export JSON in the toolbar to save your entire library to a `.json` file on your computer. You can restore or share patterns anytime via Import JSON.

8. Factory Reset & USB Rescue

USB Rescue Mode: Hold the OCT- button while turning on the FM-1 power switch. The FM-1 will boot into USB updater rescue mode, allowing you to reinstall firmware or revert to factory state over USB.
