Beatsi Eurorack Cheat Sheet
Beatsi is a compact, digital module for modular drum synthesis (not samples or physical modeling). Sounds are based on virtual drum-synth building blocks and organized into three "kits":
- Orange: Acoustic/Basic
- Blue: Low-fi
- Green: Alien
1. Panel Controls & Navigation
Encoders
- Parameter Encoder:
- Turn: Scroll parameters (Timbre, Pitch, Decay, Level) for each drum piece.
- Short Press: Assign selected parameter to CV1.
- Long Press: Edit attenuverting for CV1 on selected parameter.
- Value Encoder:
- Turn: Adjust the value for the selected parameter.
- Short Press: Assign selected parameter to CV2.
- Long Press: Edit attenuverting for CV2 on selected parameter.
- Press both encoders: Mute selected drum piece.
Button
- Hit: Plays (auditions) the selected drum voice.
Grid Section
Navigate between pieces and parameters (white cursor). The color of the value bar = kit currently in use for the piece.

3. Parameter Control & CV Assignment
- Each piece (Kick, Snare, Hi-hat, Tom, Crash) has parameters:
- Timbre
- Pitch
- Decay
- Level
- CV Assignment:
- CV1: Assign by cursor + Parameter Encoder (short press)
- CV2: Assign by cursor + Value Encoder (short press)
- Attenuverting: Cursor on parameter + associated encoder (long press). Adjust range: +1 to -1 (top squares = normal, bottom = inverted)
- Multiple parameters: Both CVs can be assigned to multiple params at once.
4. Kit Selection/Timbre Mod
- Kits: Orange (acoustic), Blue (low-fi), Green (alien)
- Switch kit for piece:
- Navigate timbre parameter to either end; value bar "rolls over," changing color.
5. Saving & Reset
- Auto-save: Wait 5 sec after last change/no trigger; cursor dims = settings stored.
- Reset All Settings: Hold Hit, Parameter, Value buttons while powering up.
6. Drum Engine Theory (Quick Ref)
- Kick/Tom: Modeled as VCO + envelopes (decay pitch, amp env.), plus optional noise/AM/FM for punch.
- Snare: Modeled with noise burst + drum VCO base.
- Cymbals/Crash/Hi-hat: Noise filtered, delays, fast amplitude env.
- Hi-hat: Trigger = closed, Gate = open.

8. Tips
- Use external LFOs, random, or sequencer CVs into CV1/CV2 for morphing/animation.
- Fast triggers on hi-hat = closed; gates or longer triggers = open.
- Save/backup settings by waiting for auto-save (no triggers/edits for 5 sec).
