Machinedrum Pitch Scaler
Machinedrum Pitch Scaler is a tonal performance utility for the Elektron Machinedrum (or any CC-controllable synth).
It provides real-time scale quantization and MIDI CC pitch output, allowing for easy melodic writing, bassline programming, and parameter-locking directly from Norns.
Author: HANJO – Tokyo, Japan
OVERVIEW
This script enables tonal control of the Machinedrum’s parameters through MIDI CC messages.
By selecting a scale and root note, you can send CC values mapped to musical notes, ensuring melodic consistency while tweaking or parameter-locking sounds.
It’s designed for both studio composition and live improvisation, turning the Machinedrum into a melodic instrument.
FEATURES
- Scales any MIDI CC values to a selected musical scale
- Allows randomized notes within the active scale for generative inspiration
- Parameter-lock compatible: easily assign key CCs to create evolving melodies
- Switchable encoder modes for flexible control:
- Channel select
- CC number
- Note step navigation
CONTROLS
| Control | Function |
|---|---|
| E1 | Change Scale Mode |
| E2 | Adjust Root Note (C, C#, D, etc.) |
| E3 | Depends on current mode: • Channel Mode – Change MIDI channel (1–16) • CC Mode – Change MIDI CC number (0–127) • Note Mode – Step through notes in scale |
| K2 | Send a Random Note from the current scale |
| K3 | Toggle E3 Mode (Channel → CC → Note → back) |
DISPLAY
The on-screen interface provides real-time feedback for:
- Current scale and root note
- Active MIDI channel and CC number
- Encoder mode (Channel / CC / Note)
- Last note sent (number + name)
