Today I made a midi controllable motor with a phono socket to hook it up to the msar. I am going to do some motors that, when triggered, do something mechanical, ie turn something to make a sound, strike something or possibly create a strumming motion. However this one I have just been playing through a tape deck head of a hacked walkman. Its interesting as a dry sound but I can get some good sounds by feeding the walkman through an effects unit. Here is a short sample, starts dry and then I dial in a chorus/reverb effect..
