Usage

Basic Example

Just ask Claude naturally:

"Create a trap beat for my EP-133 with heavy 808s and hi-hat rolls"

Claude will:

1. Set up samples on the appropriate pads
2. Program the pattern with proper timing
3. Generate a .ppak file you can download

Getting Your Device SKU

For the generated file to work, Claude needs your device's SKU. Get it by:

1. Open EP Sample Tool
2. Connect your EP-133
3. Create a backup
4. Share the backup file with Claude

Claude will extract the SKU automatically.

Example Prompts

Prompt	What Claude Creates
"Make a lo-fi hip hop beat with dusty drums"	Swung groove, vinyl snares, airy hats
"Create a 4-on-the-floor house pattern"	Classic kick pattern, offbeat hats, disco claps
"I want a jungle/DnB breakbeat"	Chopped amen-style break at 160+ BPM
"Generate something weird and experimental"	Polyrhythmic chaos, glitchy textures

• ZIP structure with leading-slash paths
• TAR archive containing pads, patterns, and settings
• Binary pattern format (8 bytes per event)
• Group/pattern relationship (pattern filename determines sample group)

See references/format-details.md for complete specifications.
