Bent Musini - Crazy 16bit Stereo Soundscapes

via this auction
"The Musini is a musical toy that little kids put on the ground. It plays music in time with the vibrations of their kid feet dancing around. Lights flash and the 16bit 44.1khz sound chip pumps out LOUD stereo music through the built in speakers. It is powered by batteries or wallwart (not included). It also has a headphone jack. Pretty damn cool and built very solid.

I don't get excited about most circuit bent stuff becaue it all kind of sounds the same to me. This bent Musini does NOT sound like a bent Casio! CD quality, stereo sounds with reverb, chorus, and other effects all stream out of this Musini. It's a rare beast because Musini's are still popular for their intended purpose thus tough to find and also because it's an easy machine to fry while looking for bend points.

From right to left, the mods are:

* Glitch Button: Press this button to start the fun, keep pressing to descend into more chaos.

* Power Starve Knob: Rotate this clockwise to simulate the batteries failing. Using this and the glitch button at the same time will keep you busy for years.

* Pitch Knob: Turn this knob counter-clockwise to lower the pitch of whatever noise is spewing out.

* Reset Button: If the Musini seems to be stuck and responding to the Glitch button, press Reset; it's the same as turning it off then on again but easier than finding the power switch on the underside.

* Hold Switch: The Musini is motion activated. If you get tired of making motions, flip the Hold switch and it will usually hold at the tempo it's currently at, but sometimes it just goes to a tempo of about 60bpm.

Using the different controls in combination with each other and the stock Musini controls yields widely-varied results. Even adjusting the volume or using the headphone jack instead of the built in speakers makes the Musini emit all kinds of different weirdness. The controls interact with each other in strange but magnificent ways."
