I used to own an Ensoniq Mirage DSK sampler, and one of the coolest things I have ever done with it. Was to sample feedback into it. I took a microphone, plugged into the mirage. Turned on my amp and held the mic to the speaker. Sampled the sound, and played it on the keyboard. It sounded almost like an electric piano.

Still miss my sampler. Of course I should have gone with the EPS16+. Oh well.
