Host parameters
This page lists every parameter ScratchCraft shows to your DAW, grouped the way hosts list them. Use it when you automate ScratchCraft, map it with your DAW’s own MIDI mapping, or set up a control surface.
Parameter names are shown here as your host displays them, with “Deck A” standing for “Deck A” or “Deck B”, and “Pad 1” for any pad from 1 to 32.

Recording scratches as automation
Section titled “Recording scratches as automation”Scratch and Touch together are the hand on the record. When you drag a platter on screen near the cue point, ScratchCraft reports both to the host, so a hand scratch can be recorded as automation and played back. While you hold the platter, the deck follows your mouse and ignores the automation; on playback, Touch on makes the deck follow Scratch.
Pads 1-16 and Pads 17-32
Section titled “Pads 1-16 and Pads 17-32”Each pad has nine parameters, named “Pad 1 …” to “Pad 32 …”. They are not automatable: hosts leave them out of their automation lists. Set them in the rack’s pad inspector, or map them with MIDI Learn.
| Name | Range | Default | Notes |
|---|---|---|---|
| Pad 1 Pitch | −12 to +12 st | 0 st | |
| Pad 1 Rate | 0.25x, 0.5x, 1x, 2x, 4x | 1x | Shape pads. |
| Pad 1 Play Mode | Trigger, Gate, Latch | Trigger | |
| Pad 1 Quantize | Global, Off, 1/32T, 1/32, 1/16T, 1/16, 1/8T, 1/8, 1/4, 1/2, Bar, 2 Bars | Global | Global follows Pad Quantize. |
| Pad 1 Level | 0 to 200 % | 100 % | 200 % is about +6 dB. |
| Pad 1 Speed | 0.25x to 4x | 1x | One-shots. |
| Pad 1 Pan | L 100 to R 100 | C | Mono, Poly and Platter one-shots. |
| Pad 1 Filter | LP 100 % to Off to HP 100 % | Off | Mono, Poly and Platter one-shots: lowpass to the left, highpass to the right. |

FX A and FX B
Section titled “FX A and FX B”Each deck’s effect rack has 63 parameters, all automatable. The rack switch is Deck A FX (Off / On, default On). Every unit then has an On switch (default Off) and a Mix, followed by its own controls. Names follow the pattern “Deck A Unit Control”, for example Deck A Tape Echo Time.

What isn’t a host parameter
Section titled “What isn’t a host parameter”Some things in ScratchCraft are set only in its own window and saved with the project, not exposed to the host:
- Playing pads. Pads are triggered by MIDI notes, not parameters.
- Pad settings other than the nine above: the pad mode, Shape, sample and its Start and End, target deck, release, choke group, velocity, envelope, one-shot options and utility actions.
- Capture, the capture and take lengths, and recording takes.
- The Shape editor: Shapes, their nodes and the technique generator.
- Samples: which sample is loaded, its tempo, beat grid and musical key, and the deck Edit menu.
- The Feel options, the MIDI map, session states and slots.
- The standalone app’s tempo, time signature and click.
ScratchCraft’s own MIDI Learn can still reach many of these: pad notes, session slot recalls, rack banks, capture and the deck jog, scratch and touch targets.
