Multigrain
Live Stereo Morphing Granular Sampler with instant access to eight Sounds, played back through a granular engine with morphable scenes and a reverb effect called Blur.303
Capabilities 4
- CV Recordercv-recorder
- Two recorder workflows: Sample Recorder (record from inputs or resample outputs, up to 32sec, always-listening) and Looping Recorder (tape-loop style with auto-crossfade, 8/16/24/32sec length, supports live sounds). Advanced sample trimming and normalization available.303
- Granular Samplergranular-sampler
- Eight-channel stereo granular engine generates grain streams from up to 32-second stereo WAV samples or live audio input. Full control over grain position (START/SCAN/WRAP), size (20ms–4sec), pitch (±2 oct), shape (7 envelope types), level, and tone (2-pole HP/LP per grain).303
- Pitch Quantizerpitch-quantizer
- Per-sound 12-TET pitch quantizer with selectable scale, root note, and two quantization modes (PITCH knob + mod, or mod only). Can copy quantizer settings across Sounds.303
- Reverbreverb
- Built-in Blur reverb effect applied end-of-chain to all grain streams. BLUR knob simultaneously controls per-grain send amount and overall reverb decay. Also applied to audio passthrough when THRU is enabled.303
Jacks 15 — 11 in / 4 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (11) | |||
| GATE | gate | ≥2V | Gate input (>2V) that triggers the currently playing Sound. By default the SCAN position auto-resets on each trigger received here; the auto-reset can be moved to NEXT via the System Settings page (firmware 1.2+). When GATE is unpatched it receives whatever is patched into NEXT through the hardware normal.303 |
| IN L | audio | — | 303 |
| IN R | audio | — | 303 |
| MORPH | cv | -10V to 10V | CV input that modulates the position of the MORPH fader. ±5V sweeps the full MORPH range. MORPH ATT knob acts as attenuverter; fader acts as offset.303 |
| NEXT | trigger | ≥2V | Trigger input (>2V) that advances Multigrain to the next Sound. Optionally configurable as a SCAN reset input via the System Settings page (firmware 1.2+); in that mode SCAN no longer auto-resets on GATE and is reset only by a trigger here. Hardware-normalled to GATE — when GATE is unpatched, the signal patched into NEXT is also passed to GATE, so a single gate into NEXT both advances the Sound and triggers it.303 |
| SELECT | cv | -10V to 10V | CV input that determines which Sound is playing. SOUNDs 1-8 mapped across 0V to 5V; negative voltage is rectified (mirrored). Empty Sounds are ignored.303 |
| START | cv | — | 303 |
| SYNC | clock | ≥2V | 303 |
| X | cv | -10V to 10V | Assignable modulation CV input; ±5V sweeps any parameter range. Can be used for V/Oct pitch control of PITCH when assigned at 100% depth.303 |
| Y | cv | -10V to 10V | 303 |
| Z | cv | -10V to 10V | 303 |
| Outputs (4) | |||
| A | cv | — | Assignable modulation output CV. Default: Morph fader position. Options: Morph position, Grain trigger, Grain envelope, Envelope follower (input), Envelope follower (output), Random S&H, Grain pitch, Record trig/gate, Threshold gate.303 |
| B | cv | — | Assignable modulation output CV. Default: Grain trigger. Options same as A output: Morph position, Grain trigger, Grain envelope, Envelope follower (input/output), Random S&H, Grain pitch, Record trig/gate, Threshold gate.303 |
| OUT L | audio | — | 303 |
| OUT R | audio | — | 303 |
Parameters 22
| Name | Type | Range | Behavior |
|---|---|---|---|
| BLUR | knob | — | Controls reverb send amount per grain and the overall reverb decay simultaneously. Increasing CW increases both send and decay. If THRU is enabled, input is also sent through Blur at the same level as the playing Sound.303 |
| Fine Tune | knob | -7semitone – 7semitone | Fine-tune pitch for the active Sound, ±7 semitones. Independent of the PITCH knob and not affected by Quantization. Available on Alt Page via the PITCH knob. LED is YELLOW if pitched up, PURPLE if pitched down, OFF if no fine-tune applied.303 |
| GAIN | knob | 0.5 – 8.5 | 303 |
| Gate Delay | menu_setting | 0ms – 8ms | 303 |
| LEVEL | knob | — | Sets the output volume of each grain. When RAND is applied in CCW direction, random modulation is applied with opposite polarity to left and right channels, creating a random panning stereo effect.303 |
| LOAD | button | — | Alt Panel workflow button: opens the sample browser to load a sample from the microSD card into the current sound slot. Located on the Advanced Sampling Panel either side of the grey waveform icon, above the MOD label. Hold-on-boot displays one digit of the current firmware version via LED color.303 |
| MORPH ATT | knob | — | Attenuverter for the MORPH CV input. Controls level and polarity of the incoming CV; MORPH fader acts as offset. ±5V at input with full positive attenuation sweeps the full MORPH range.303 |
| MORPH fader | fader | — | Determines the Sound's parameters by interpolating between Scene A (fully left) and Scene B (fully right). Universal — position is what you hear regardless of which Scene is active for editing. REVERSE and SHAPE are discrete (probability-based morph). All grain parameters morph simultaneously.303 |
| PITCH | knob | -2octave – 2octave | Sets grain playback speed/pitch. ±2 octaves (±3 with modulation). Unquantized by default; can be linked to Quantizer. LED is GREEN at original pitch and octave intervals, RED otherwise, PURPLE when Quantizer enabled. Fine-tune (±7 semitones) available on Alt page.303 |
| PROJECT | button | — | Alt Panel workflow button: switches between projects on the microSD card (a project is the top-level container holding presets, scenes, and sample assignments). Located on the Advanced Sampling Panel either side of the grey waveform icon, above the MOD label. Hold-on-boot displays one digit of the current firmware version via LED color.303 |
| RATE | knob | 0Hz – 130.813Hz | Sets frequency of grain generation from 0Hz (single grain on trigger) to 130.813Hz. Can be synced to external clock via SYNC input. When RATE–SIZE linked, RATE multiplies the base rate set by SIZE from 1x to 8x.303 |
| RATE–SIZE Link | button | — | When linked, SIZE determines the base rate of grain generation (smaller size = faster rate). RATE then multiplies this base rate from 1x (fully CCW) to 8x (fully CW). Per-Sound, applies to both Scenes.303 |
| REVERSE | button | — | Toggles playback direction of grain audio. Does not affect SHAPE or SCAN direction. Per-Scene setting. Long press activates Ping-Pong mode. When morphed between Scenes with different REVERSE states, morph position determines probability of each new grain using Scene A or Scene B value.303 |
| SAMPLE | button | — | Alt Panel workflow button: opens the Sample Recorder for capturing audio into a new sample. Located on the Advanced Sampling Panel either side of the grey waveform icon, above the MOD label. Hold-on-boot displays one digit of the current firmware version via LED color.303 |
| SAVE | button | — | Alt Panel workflow button: writes the current preset / project state to the microSD card. Located on the Advanced Sampling Panel either side of the grey waveform icon, above the MOD label. Hold-on-boot displays one digit of the current firmware version via LED color.303 |
| SCAN | knob | — | Advances the start point of each successive grain through the area defined by START and WRAP. CW moves forward, CCW moves backward. Centered = static start position. Resets to START on SOUND press or GATE.303 |
| SHAPE | knob | — | Selects the style of amplitude envelope applied to each grain from 7 options. SHAPE is a discrete value — morphing between Scenes determines the probability of each new grain using Scene A or Scene B value.303 |
| SIZE | knob | 20ms – 4000ms | Sets grain length from 20ms to 4sec (centered ≈ 1sec). Maximum extendable to 8sec or full sample length via System Settings. When SIZE–PITCH linked, SIZE sets amount of audio content and grain length scales with PITCH playback speed.303 |
| SIZE–PITCH Link | button | — | When linked, SIZE sets the amount of audio content per grain and PITCH adjusts playback speed while also scaling grain length to maintain the same audio content. Useful for changing pitch of a specific phrase while maintaining the audio content in the grain.303 |
| START | knob | — | Sets the start position in the sample from which grains are generated, ranging from the beginning to the end of the sample. Resets to START position when SOUND button is pressed or GATE received. With Live Sounds, fully CW processes the most recent audio in Live Memory.303 |
| TONE | knob | — | Controls a 2-pole HP/LP filter applied per grain. CCW applies lowpass, CW applies highpass, center applies no filtering. When RAND is applied CCW, stereo panning modulation is created by applying opposite polarity to L and R channels.303 Zones
|
| WRAP | knob | — | Defines the area through which SCAN advances grain start positions. When SCAN reaches the WRAP position, the start position wraps back to START.303 |
