Droid Emmoder Eurorack Sequencer Configuration

Configure and develop performance sequencers for the Droid Universal CV Processor, focusing on multi-track drum sequencing with algorithmic pattern generation.

Overview

You will work with `droid.ini` configuration files for the Droid Universal CV Processor, a Eurorack modular synthesizer control system. The configuration defines circuits, signal routing, and hardware mappings using INI-style syntax with specialized Droid circuit blocks.

Hardware Context

The Droid system consists of modular components:

Hardware references use module notation: `P1.1` (potentiometer 1 on P10), `B2.1` (button 1 on P2B8 #2), `G1.1` (gate 1 on G8).

Configuration Structure

File Organization

The `droid.ini` file contains:

1. **Clock Management**: LFO and external clock handling

2. **Reset System**: Global reset functionality

3. **Page System**: Multiple control modes

4. **Drum Sequencer**: 4-track algorithmic pattern generation

5. **Motoquencer**: CV sequencing with quantization

6. **Control Mapping**: Button, potentiometer, and LED assignments

Common Circuit Types

Development Workflow

Step 1: Reference Documentation

**Always consult these resources first:**

Step 2: Edit Configuration

Modify `droid.ini` following these patterns:

**Signal Routing Example:**

```ini

[copy]

input = I1 # External clock input

output = _CLOCK # Internal clock signal

```

**Drum Track Example:**

```ini

[algoquencer]

button = B2.1, B2.2, B2.3, B2.4 # Step buttons

gate = G1.1 # Kick drum output

clock = _CLOCK

activity = P1.2 # Pattern density

variation = P1.3 # Pattern variation

```

**Mute Logic Example:**

```ini

[logic]

input1 = _TRACK_SELECTED

input2 = B4.8 # Mute button

and = _KICK_MUTE_TRIGGER

```

Step 3: Update Documentation

**CRITICAL**: After any change to `droid.ini`, update `README.md` to reflect:

**Language Requirement**: All documentation (README.md, code comments, commit messages) MUST be in English.

Step 4: Version Control

Commit changes with descriptive English messages:

```bash

git add droid.ini README.md

git commit -m "Add snare track variation control on P1.4"

```

Step 5: Hardware Testing

1. Copy updated `droid.ini` to SD card

2. Insert SD card into Droid Master module

3. Power cycle or reload configuration

4. Test functionality on hardware

5. Iterate as needed

Common Patterns

Exclusive Button Selection

```ini

[buttongroup]

button = B4.1, B4.2, B4.3, B4.4

led = B4.1, B4.2, B4.3, B4.4

value = _TRACK_SELECTION

```

Clock Division

```ini

[clockdivider]

clock = _CLOCK

divide = 4

output = _DIVIDED_CLOCK

```

Step Sequencing

```ini

[algoquencer]

button = B2.1, B2.2, B2.3, B2.4, B2.5, B2.6, B2.7, B2.8,

B3.1, B3.2, B3.3, B3.4, B3.5, B3.6, B3.7, B3.8

length = 16

gate = G1.1

activity = P1.2

```

Key Variables

Global Signals

Per-Track

Motoquencer

Troubleshooting

1. **Configuration not loading**: Check INI syntax for typos, missing brackets, or invalid circuit names

2. **Hardware not responding**: Verify module addresses match physical setup

3. **LED behavior unexpected**: Check `led` parameter assignments in button circuits

4. **Gate outputs silent**: Verify `gate` routing from sequencer to G8 outputs
