Circuit bent keyboard with an other toy inside (for sale)

mini jack out (mono) don’t use a headphone because the sound will be only at one side

2 switch for random notes or drum. It can be used for produce permanent drone. 1 switch make higher notes than the other.
1 input jack for cv (pitch). It works good with korg sq-1 but be careful to adjust the pitch potentiometer right or it might crash. If it does just restart the keyboard.
an other toy (drive wheel) inside with a pitch potentiometer and several press button for play drive sounds and melodies. One of the sound which is a little like a bass drum can be triggered with the cv input.
