CARA is Antumbra’s clone of the Mutable Instruments Marbles “random sampler”. That’s sampler in the sample and hold sense rather than the Akai sense.
Got the boards from Pusherman, built and flashed the brain.
Then populated the rest of the boards.
The pin headers to join the two boards were very fiddly. The calibration process is a little trickier than usual as it involves taking accurate readings from all outputs, editing and recompiling the code, then reflashing the STM32. This thing’s amazing though, loving it.
I still need to install the jacklights as I ran out of the 180R resistors used in that circuit.
