Designed by and for musicians, Stepper Acid was born out of Transistor Sounds Labs’ need for a modern step-sequencer. Many of its features are geared up for live use – for example, the ability to play one pattern whilst entering a new one.

Dual microcontroller design ensures tight timing: one runs the sequencer, the other the front panel interface.
