i initially had trouble getting the SA9 to glitch until i realized that the trick is quick momentary connections. this little guy spits out some crazy and amazing sounds! you generally have to coax it a little to get the really fantastic stuff, but it’s capable of some great long evolving glitches.
across the top the additions are: 1/4″ output, patch burp switch (causes it to rapidly change patches), rotary switch for ranges of patches burped, overdrive/feedback switch with knob for amount, main glitch button, 2nd noisy glitch button, led and power switch.
here is an example of the burp, overdrive and glitches:
and a diagram of the main bends:
here’s a less abstract version of the diagram above:
2 oscillators with pitch control, and an overall tone/volume control. the 2 oscs interfere with each other and cause interesting noise and pitch stepping. i added an 555 based lfo and cv inputs with depth control to modulate each oscillator. also cool retro knobs.
the insides.. messy jumble of wires and perf boards..
here is a clip with osc1 being modulated by an external lfo, and osc2 by the internal one:
