2 octaves monophonic (5Volts CV) keyboard with 5 octaves selector knob. Powered by ATBase, or to use standalone with USB to stereo mini jack adapter. With the ATKeys CV module 5 octaves can be generated as CV signal (0-5V = 1V per octave). 2 octaves can be selected via the octave potentiometer and are available on 24 keypads. At the same time a gate signal goes to the output, which can be switched to a continuous signal by the latch switch. You can either connect it directly to the ATBase via the red jack or use it standalone with a USB to mini jack adapter for any CV capable device.

Status: v2 kit, available
