Here we have a clone of the most recent addition to the well-known Kastle series of mini-modular synths from Bastl Instruments, the melodic-generator “ARP”. In the original, the root note can be selected in ‘boot mode’ reached when powering on,  but in this version there is a boot switch (because it's easier than switch your whole rack off and back on).

Once more the module breaks away from the regular AE Modular input/output positions to feel a bit closer to the Bastl original, and red looks pretty well on it, don't you think?

We recommend you read the original manual from Bastl to greater understand what the ARP can do, but meanwhile here's a soundcloud excerpt with the Drum and ARP modules interacting:
