Transistor Sounds Labs Stepper Acid Digitally Controlled Step Sequencer

Like most of you, i have been following this next project for a long time... but it's finally out now and the first ones have been shipped.

The Transistor Sounds Labs Stepper Acid is a 16-step Eurorack sequencer module designed by Nina Richards & Zoë Blade with live performance in mind.
The Stepper Acid was born out of our need for a modern step-sequencer.
The dual micro-controller design ensures tight timing: one runs the sequencer, the other the front panel interface.

It looks and sounds very impressive, and very easy to program... especially compared to a 303 ;-) ...
