The Musini is an elegant children's toy that plays music to a speed determined by vibration sensors. The center dial selects one of five songs, and the four large buttons select which instrument to play the song in.

My modified Musini can create glitch sounds and hold onto sounds that are being played so that the user can sculpt the sound to his desire using the pitch and power starve knobs. It is very unpredictable, and it's hard to get the same sound twice.

Features:

>Pitch Knob + Switch: This controls the overall pitch of the unit. It's control can be toggled on and off using the switch directly below the knob. The pitch can be taken from an ambient soundscape all the way down to an inaudible gargle. It can change the pitch of the sounds not only when it is glitching, but also when it is playing normal preset music.

> Power Starve Knob: This regulates how much power the unit gets. Through reducing the power, the user can warp the sound being made, and cause the unit to glitch.

> Glitch Button: When this button is pressed, the unit will either severely transform the sound that it was currently making, or it will create an entirely new sound. Sometimes it creates a stream of instrument sounds, sometimes it creates an evolving loop of ambient sound. The glitch sounds work very well with the pitch control.

> Hold Speed: Since the Musini is built to play a song when it is moved or bumped, it gets annoying to be constantly moving it in order for it to make a stock sound. When this switch is flipped, the Musini will play music at the speed that it was currently playing at. If it is switched when nothing was playing, it will play at a very slow tempo.

The sound samples are almost all just having the Musini play, pressing the glitch button, and adjusting the pitch and power knobs.




    This board scan was found on www.circuit-bent.net, with the red boxes around bendable areas. I went ahead and marked where I found the pitch shift and the glitch points.

    Glitch: Connect the bottom left pin of the lower chip to the left point of C14, which is right next to the chip. Wire                 this in with a button.

    Pitch Shift: Connect the right point of C14 to the bottom point of C16, which is above the big chip and                                     slightly to the left. On mine, I wired in a pot between the two and made it switchable.
 
    Power Starve: A standard bend, just cut the positive power lead coming into the board, and reconnect it with                             a low-resistance potentiometer in between. I used a 1k.

    Hold Speed: On the vibration sensor, there is a small PCB. There is a brown bundle of three wires coming into                             this board. Connect the black (ground) wire to the pin one below it for the hold speed mod.                                 Wire this in with a switch.
