Sequencer

Version 0.1 from October 2020

Step sequencer with gates and triggers that I built for my drum machine project. It’s based on an Arduino Nano Every.

Features

• ✅ 8 steps
• ✅ 3 tracks
• ✅ Speed control by external CV (triggers/gates forwarded with 5V)
• ✅ Speed control by internal clock (speed set by tapping, sending 5V triggers)
• ✅ Set and unset track hits on the run
• ✅ Predefined track patterns

3. Set and unset track hits (step display is running): Push the according track button once.
4. Use an external CV: Plug it in the track jack.
5. Start steps at position 1 (step display is running): Push the steps button once.
