itty bitty midi (with pikocore)

here I'm syncing the pikocore clock and start/stop and beat resetting to the midi output from the roland tb03.

the pikocore midi syncing works using a small device I call the "itty bitty midi". the "itty bitty midi" has a midi input (DIN or trs type A) which is converted out to a serial stream that can be read by the pikocore clock in. the "itty bitty midi" device can be found on my wares website (link in bio) which you can get directly from me or use the schematic to build your own (its open source and only a few components - a DIN, a resistor and two caps at minimum).

the pikocore firmware can be updated to use midi with the online tool (also link in bio) with options to change the midi clock division, synchronization behavior, etc.

hopefully in the future I can get the usb midi working too...but not quite yet. still a goal.

and just a note that I've totally floored by all the astounding pikocore creations - music-wise and hardware-wise. there are now several alternative pikocore firmwares out there (link in bio) which can be used to make pikocore become different things, which is totally amazing and just shows how incredible open-source can be. never stop!"



"itty bitty midi a simple circuit that takes either a midi din input or a midi trs type-a input, and converts it to a logic-level serial bit stream. the resulting bit stream can be used by *core devices (like the pikocore) to listen to midi signals directly through the clock inputs.

there are two versions of this product, select the one that suits you: the active version utilizes a battery-powered circuit with the 6n138 optocoupler to effectively isolate the downstream and upstream devices. the passive version does not use isolation and has no battery.

the itty bitty midi is open-source."
