Instruments

Synth Designer, Forge Steel, Sampler, Granular, Noise Lab.

Every instrument in EDM Forge follows the same shape: an overview, a parameter map, a quick try it recipe, and the gotchas we wish someone had told us. Each one runs standalone in the Studio and — for the Forge Steel family — drops straight into the modular rack as a patchable module.

Synth Designer

The everything-synth

A modern wavetable / virtual-analog hybrid. Two oscillators, sub, noise, dual filters, three envelopes, three LFOs, an eight-slot mod matrix, plus an effects chain. Use this when you want a single device that can be a saw lead, a wobble bass, a pad, or a pluck without leaving.

Parameters

OSC 1 / OSC 2Wavetable + analog shape. Unison 1-16, detune, phase, pan spread.
SUBSine / square / triangle, octave switch.
NOISEWhite / pink / sample-hold, dedicated filter send.
FILTER A / BLP, HP, BP, Notch, Comb, Formant. Series or parallel routing.
ENV 1-3ADSR with curve controls. ENV 1 hard-wired to amp.
LFO 1-310 shapes, host-sync, retrigger per voice or free-run.
MOD MATRIX8 slots — any source → any destination, bipolar amount.
FXReverb, delay, chorus, phaser, distortion, compressor.

Try it

  1. Load preset 'Reese — Drift'
  2. Increase OSC 1 unison to 7, detune ~25%
  3. Route LFO 2 → Filter A cutoff at ~40%
  4. Add a quarter-note delay with 35% feedback.

Gotchas

  • Unison voices stack CPU fast — 16 × OSC 1 + 16 × OSC 2 = 32 voices per note.
  • Mod matrix is bipolar. If a knob is fully clockwise, +100% modulation drives it out of range and silently clips.

Forge Steel Series

Four flagship synths, each named after a layered-metal craft. Each one runs standalone and also appears in the modular rack as a single patchable module — your existing patches and CC mappings carry over verbatim.

Demascus

Wavetable

Folded-steel wavetable synth. Two wavetable oscillators with morphable position, a unique 'fold' shaper that mimics steel forging, and a vowel filter bank for vocal-like leads and pads.

Parameters

WT POS A / BScrub through the wavetable. Modulate for movement.
FOLDWave-folding amount — adds odd harmonics.
VOWEL FILTER5 vowel formants, morphable via the X/Y pad.
MOTIONSlow drift LFO targeting WT POS, FOLD, and FILTER simultaneously.

Try it

  1. Patch 'Cathedral Pad'
  2. Push MOTION to 60%
  3. Sweep the VOWEL XY in time with a slow attack.

Gotchas

  • FOLD past 80% can introduce DC offset — keep a high-pass at ~30 Hz on the master.

SanMai

FM

Three-layer FM synth — outer, core, outer — modelled after the 3-ply san-mai forging technique. Six operators with a fixed bell-clean topology that's easier to dial in than a classic DX-style matrix.

Parameters

OP 1-6Each: ratio, fine, level, envelope (4-stage).
FEEDBACKPer-operator feedback for noise-like timbres.
ALGORITHM12 hand-picked algorithms covering bass, bells, pads, plucks.
VELO → INDEXHard-wired velocity to modulation index — touch sensitivity for free.

Try it

  1. Algorithm 3 + carrier ratios 1, 2, 3
  2. Set OP 6 feedback to 0.8 for a noisy attack.

Gotchas

  • Operator levels are exponential. Going from 95 → 100 is a much bigger jump than 50 → 55.

ColdWeld

Hybrid

A laboratory hybrid: virtual-analog oscillator + granular layer + physical-model exciter, all running in parallel and bonded by a shared filter and envelope. Designed for sounds that don't fit a single category — metallic plucks, breathy basses, broken keys.

Parameters

ANALOG OSCSaw / pulse / triangle, PWM, hard-sync.
GRAINSample slot + size, density, position scatter.
EXCITERKarplus-Strong with damping, position, and a noise burst.
WELDBond amount — cross-modulates the three layers.
SHARED FILTERDrive-and-feedback LP/HP, post all three layers.

Try it

  1. Drop an 808 sample into GRAIN
  2. Pull ANALOG OSC level to 60%
  3. Push WELD to 70% and play C1.

Gotchas

  • GRAIN streams from your sample — switching presets reloads. Keep grain samples short (<2 MB).

Filigree

Additive

64-partial additive synth with a spectral brush. Paint a harmonic profile, draw partial envelopes, then morph between four snapshots over time.

Parameters

PARTIAL BRUSHPen-style editor for harmonic amplitudes 1-64.
MORPH XYInterpolates between snapshots A/B/C/D.
DETUNEPer-partial detune for analog feel.
SPECTRAL DELAYEach partial delayed independently — creates risers and gestures.

Try it

  1. Brush a 'pluck' profile (high low partials, decaying highs)
  2. Animate MORPH from A → D over 4 bars.

Gotchas

  • With 64 partials and >8 voices, CPU is heavy. Use 'Voice Limit' to cap polyphony.

Sampler Deck + Pads

One-shot & loop player

Drag any audio onto a pad slot or the sampler deck. The deck is for melodic playback (mapped across MIDI), the Pads device is the 16-pad finger-drumming grid.

Parameters

ZONESMulti-sample mapping — split by velocity or note range.
PITCH / GAINPer-pad, semitones + dB.
VELOCITYPer-pad curve (linear / log / fixed).
CHOKE GROUPSGroup pads so one cuts off the others (classic open-hat / closed-hat).
WARPOptional time-stretch for loops; locks to project BPM.

Try it

  1. Drop a 909 kit on Pads
  2. Put closed/open hats on choke group 1.
  3. Record-arm and finger-drum 8 bars.

Gotchas

  • Warping a one-shot smears transients. Keep warp off for percussion, on for loops.
  • Pads device uses sample-accurate triggering; choke groups behave like hardware drum machines.

Granular Engine

Texture sculptor

Granular sampler designed for pads, textures, and risers. Load a sample, the engine spawns grains across it — control density, position, size, pitch spread, and panning per-grain.

Parameters

GRAIN SIZE5 ms – 500 ms.
DENSITY1-200 grains/sec.
POSITIONWhere in the sample new grains start. Modulate for scrubbing.
SCATTERRandom offset per grain.
PITCH SPREADRandom ±semitones per grain — wide for clouds, 0 for tight.
FREEZEFreezes the buffer in place — playhead stops but grains keep firing.

Try it

  1. Load a vocal phrase
  2. FREEZE on, DENSITY 80, PITCH SPREAD 0.5
  3. Play long chords.

Gotchas

  • High density × wide pitch spread = aliasing on bright source material. Drop a soft LPF after.

Noise Lab

Experimental sound design

Four engines under one device: FM noise, Karplus-Strong, spectral, and the 'uncertainty' chaos engine. Shared mod matrix and an output FX chain make it a one-stop shop for risers, impacts, atmospheres, and SFX.

Parameters

ENGINEFM noise / Karplus / Spectral / Uncertainty.
MOD MATRIX6 slots, sample-and-hold and chaos sources included.
HUMANIZEAdds per-trigger micro-variance to every parameter.
VARIATIONSSaves N parameter snapshots; cycles between them as you trigger.

Try it

  1. Engine: Uncertainty
  2. Bind chaos source → filter cutoff at 60%
  3. Trigger with a quarter-note clock.

Gotchas

  • Uncertainty is non-deterministic — bouncing twice gives different results. Bake to audio when finalizing.

Drum Kit & PolySynth

Default voices

The 'just give me something' voices. The Drum Kit is the 909-style default behind new drum tracks; the PolySynth is the simple 2-osc subtractive behind new melodic tracks. Both are designed to sound good with zero tweaking, but every knob is still there.

Parameters

DRUM KITKick / snare / hat / clap / tom voices — each with pitch, decay, tone.
POLYSYNTHOSC A+B, sub, LP filter, ADSR amp + filter envs, single LFO.

Try it

  1. New project → the default track is already a PolySynth. Hit Z–M to play.

Gotchas

  • Both are deliberately CPU-light. For bigger sounds, swap to Synth Designer or a Forge Steel device.
Pro
Every device here can be controlled by a hardware controller via MIDI Learn — right-click any knob, hit Learn, wiggle a CC, done.
