Circuit Bending the Bliptronic 5000


I finally got a chance to bend my Bliptronic 5000, and while I was sad that there was no active synthesis, I’m pretty satisfied with the results.

First, I replaced the internal crystal with a Getlofi Precision Oscillator kit.  That was easy, and it’s very responsive.  I ended up adding a 25k resistor to limit the upper range of the precision oscillator, because the Bliptronic was prone to crashing during any attempt to “speed up” the sample rate.  Sampling down was fine though, and the downward range is quite huge.

I also found a spot on the audio IC that creates a rich harmonic drone.  I should note here that this bend should be done through resistance- I used a 500k pot and found that the audio would distort and cut out when resistance approaches zero.

Additionally, I used a HighlyLiquid MD24 kit to send 5v pulses to the Bliptronic’s Sync In jack, which let me send a MIDI note from Ableton Live to start the Bliptronic’s sequence at the start of each measure.  This allows the Bliptronic to sync with my other devices with relatively good timing.
