Let me tell you these things are something else. Excellent quality music samples in real stereo, and on top of that it’s a glitching beast. Fresh off my first couple of successful external osc. experiments I decided to give a Musini a second try. I had opened when of these up once before, and fried it within a half an hour, but Jeff told me through one of the benders groups that there were good bends to be had, so I gave it a go.
Thanks to Jeff’s tips I found the random crashy points pretty quickly, and I thought it would make a large difference if I could add pitch control. The weird thing about Musini’s is that they have not one, but two xtals inside. The first one I picked to replace was incorrect, so I tried that second one. That really didn’t work either, so I started probing around the circuit with my osc’s signal on a probe wire. I found c16 on the board would accept the osc’s signal, and lower the pitch. I added a 2 inverter setup, one side for the pitch, and another side setup to loop. I poked around with the signal for the looping osc, and found a way to trigger the toy using the osc to keep the toy playing. Normally a Musini would sense vibrations from children dancing, and play music to it roughly in time. By adding the LFO I can control the speed that the music plays, and keep it playing while I’m trying to get it glitching.
The second Musini design I used was more effective and simple. I found a way to control the pitch without the use of oscillators, and the pitch range is much greater then before. I added the pitch control with an on/off switch, LFO to retrigger the motion sensor with rate LED, rate control knob, and on/off, Glitch push button, reset push button, and main power switch.
After much poking around, searching online, and drilling of holes I’ve created “Musini Ultimate”. I now use a tap tempo and tempo lock switch in lieu of the LFO, Pitch controls are the same as are the Glitch and Reset. There is also a new distortion section with 2 way center off switch with one side going to an effect knob, Power starve knob, and a set of white noise body contacts. I got some of these mods from Arcturus, and Intelligent Machinery, besides my own notes.
I generally charge 85. for a “Musini Ultimate” plus shipping. If you are interested in one please write through the Contact Page and we can talk about availibility.
