Shape the sound

Drum Rack and generated sounds

Shape five drum voices, choose models and controls, and load generated sounds or ready-made beats.

Drum Rack puts five sounds on one track: Kick, Snare, Hat, Clap and Percussion. Each pad has a model and its own sound settings. Write the rhythm in the drum roll, then shape the sound in the Device dock.

Choose Drum Rack in the instrument selector. Press a pad in Pads to select it and audition it. The rest of the card edits that pad. The pad buttons also display each pad's current model.

Models and source controls

Use Voice model to choose a model for the selected pad. The Source section shows the controls that belong to that choice.

Pad and model Source controls shown
Kick — 808 sine sweep Tune, Sweep, Pitch decay, Body, Snap.
Kick — 909 click + body Tune, Sweep, Pitch decay, Body, Snap.
Kick — FM thump Tune, Sweep, Pitch decay, FM amount, Snap.
Snare — Tone + noise Tune, Body, Noise, Snap.
Snare — Ring modulation Tune, Body, Noise, FM amount, Ratio.
Snare — Rimshot Tune, Body, Snap.
Hat — Filtered noise Noise, Snap.
Hat — Metallic FM Tune, Ratio, Noise.
Clap — Multi-burst noise Noise, Bursts, Spread, Snap.
Percussion — Tom, Conga or Blip Tune, Sweep, Pitch decay, FM amount.
Percussion — Cowbell Tune, Ratio, Body.

These controls all use a 0–100 scale. Their main jobs are:

Control Effect
Tune Moves the generated source's base pitch.
Sweep Sets the transient pitch-modulation amount.
Pitch decay Sets how quickly that transient falls away.
Body Sets the tonal component for the noise-based snare models. The visible Body settings on kick, Rimshot and Cowbell do not change their current generated tone level.
Noise Changes the noise component.
Snap Changes the sharpness of the amplitude attack.
FM amount Changes the modulator signal's contribution.
Ratio Changes the modulator's frequency relative to the source.
Bursts Changes the clap's repeating-delay feedback, affecting its repeated texture.
Spread Changes the spacing of those clap repeats.

The pictures above Source are sketches of the settings. They do not display a live waveform or measured spectrum.

Filter, decay, drive and output

Every pad has these sections after Source:

Section Controls
Filter LP / BP / HP chooses low-pass, band-pass or high-pass; Cutoff sets frequency and Resonance emphasises the cutoff region.
Amp Decay sets how long the drum sound falls away.
Drive Drive increases soft clipping.
Output Level sets the pad level; Velocity sets sensitivity to note velocity.

At Velocity 100, softer note velocities produce softer hits. At Velocity 0, the pad uses a fixed input level. The track's mixer level still applies to the combined rack.

Pan and Choke group are visible but disabled. The card states Per-pad pan and choke are unavailable in this Grid sampler. Use separate tracks if you need separate drum panning. The track's Pan control works on the entire rack.

Drum sound settings rebuild the generated material used by its sampler. The ordinary track automation picker also lists pad parameters, but those pad lanes and modulation routes do not drive the current generated samples over time. Use direct pad edits for a fixed sound, or build the movement into a custom Grid instrument.

Reuse and reset pad settings

The buttons beside Pads are:

  • Randomise pad changes the source controls currently shown, plus Cutoff, Decay and Drive. It changes the sound, not the written rhythm.
  • Reset pad restores that pad's default model and parameters.
  • Copy pad keeps a copy of its current model and settings in the open Drum Rack editor.
  • Paste pad applies that copy to the selected pad. If its model does not belong to the destination pad, the destination uses its default model with the copied parameters.

Paste is disabled until you copy a pad. Switching to another track creates a different device editor, so use this as an editing convenience rather than a saved pad library. Use Save patch to keep a complete rack sound.

Generated sounds in Samples

The Samples panel provides audition buttons for Kick, Snare, Hat, Clap and Percussion. The play button changes to Pause while its short preview runs. Clicking the sound's name loads a single-hit pattern for it onto the selected track.

For predictable drum playback, first choose Drum Rack as the selected track's instrument, then load the sound or kit. Loading from Samples changes the track's type and rhythm but does not replace an existing instrument graph. If you loaded it onto a different synth, choose Drum Rack afterwards as well.

Right-click a sound for Audition or Stop, Load on the selected track, or Add as new track. The new-track action also needs the Drum Rack instrument selection for the reason above.

Ready-made kits

The three kits replace the selected track's notes with a drum pattern. Load applies the kit; its right-click menu also offers loading on the selected track or as a new track.

Kit Starting rhythm
Straight kit Four evenly spaced kick hits, backbeat snare, alternating hats, a clap and percussion accents.
Broken kit An uneven kick pattern with extra hat placements and percussion.
Sparse kit Fewer kick and hat hits, one snare and a percussion accent.

Loading a sound or kit clears the selected track's previous notes. Undo restores them. The material is generated in Studio; this panel has no audio-file upload or microphone recording control.

The factory preset Four on Floor chooses Drum Rack sound settings. It does not write the Straight kit beat. Choose Samples when you want a supplied rhythm, and Presets when you want a supplied sound.
