Years ago we used to do circuit bending and we had many little toy keyboards around. This one was perfect for 8bit and chiptunes genres or just for fun. A little custom GUI let you choose to extend the original range of the instrument and to enable velocity to control the volume of the instrument. There is, also, a low pass filter (just 1 pole) to cut unwanted noise from original samples. The rhythms patch has each rhythm mapped to the white keys (just like the original) and they are tempo-synced to your DAW/sequencer.
