This project is based on the bleep drum design by Dr. Bleep.
In 2025, Felix Wiegeand (wgdmodular) picked it up and released this utf-9-samplified drum machine clone with nice upgrades that make it perfect for starters and pros.
We (Modulove) put these into the hands of beginners at DIY synthesizer solder workshops in 2025.
- Few dozens were built.
- Every single one worked :)
- All were hand-soldered by beginners (even kids!).
It turned out to be a perfect entry-level project.
The new firmware adds Additonal functionality, fixes, and performance tricks that came out of those builds and feedback from users.
Stable firmware (recommended): Fixes the button confusion issue, fixed bad button behavior, small optimizations. https://dl.modulove.de/module/utf9/
Beta firmware (optional): Adds the new features: save/load slots, MIDI-to-CV clock, and more. https://dl.modulove.de/module/utf9/beta.html
