Defect Processor Buchla 289

"A few months ago I managed to snag a Defect Processor Model 289 made by Alex Pleninger (Keen Association) and Roman F

This hyper-rare module adds some appropriately bonkers digital FX to the Buchla 200 series system, by using two independent stereo digital effects units based around the rather interesting Spin Chip platform (it has two of them inside)

The module takes any audio signal and subjects it to various Spin Chip algorithms - there are 8 per section, and they are pre-set on EPROMS on the board behind the panel. The good news is you can swap out the EPROMS and change the 16 algorithms if you so desire, and you can even create your own if you get the Spin Chip programmer

I have a set that includes this insane delay patch. The module has CV inputs for some of the parameters (not many Spin-based products have this facility AFAIK) but here I am playing around with the delay times and feedback levels by hand

I’m also tweaking the 259 timbre, the LPG decay time, and the mix between Noise and VCO, and the Bandpass filter

Crazy sounds and defects abound!"
