Description

Kuensa is a small portable music sequencer which can be connected to USB MIDI and brought out whenever inspiration hits on the go. The computing is done on a Raspberry Pico RP2040 and the audio is handled by a dream SAM2695 module. The device also has serial MIDI I/O to communicate with other devices as desired. 

Internally it contains a lithium ion battery which is recharged via a USB module. Plus it's also got an SD card slot for saving work.
