Erica Synths Pico Trigger

Polyrhythmic trigger patterns in 3HP

3 HP Eurorack module

The Erica Synths Pico Trigger is a compact 3HP master clock and polyrhythmic trigger pattern generator for Eurorack systems. It stores up to 8 user-designed patterns of four independent trigger tracks with variable step lengths, enabling complex evolving polyrhythmic drum and percussion sequences. Patterns are designed in a web-based interface and uploaded to the module via audio jack, making it a powerful performance-ready trigger hub.
