  1. I’m glad they expanded it, the keys really do feel better than any other mini I’ve played besides the Yamaha Refaces, and they sadly do not all have pitch and mod that transmit over usb.

    Only thing that makes me roll my eyes here is all the panel space that went into the over complicated chord mode… more silliness for people who go around telling people they’re dance music producers. Maybe if you play music on keyboards just learn to play chords.

    Cool that they also send MIDI CCs. Would have been really nice if they put a few of their digital LFOs like on the Brutes on there with CV outs… any semi modular you’re using this to control will always benefit from having a few more LFOs with attenuators around
