Defect Processor Buchla 289

video upload by Memetune Studio

"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!"

Hope you enjoy it!🤙🏼

"As I'm sure you know, these are extremely rare. I believe only 20 or 30 were made. I hate to sell it since this is truly my dream controller but family needs call for me to part with some of my beloved gear.

Comes with the Keen case and 2 ribbon cables (only one shown) that connect to the Keen Smart Cab. I made a ribbon cable to bus cable connector to connect it to busboards from Samodular, Studio H, and of course Buchla.

It has the latest firmware."

Keen Association Keen-o-Tron - Chamberlin and Mellotron Desktop Unit w/ Touch Keys

via SOUNDMIT

"We were extremely inspired by Chamberlin/Mellotron idea, sound and topology and couple of years ago started working on the musical instrument we called Keen-o-Tron.

The instrument handles sixteen meticulously selected Chamberlin and Mellotron sounds accurately sampled from the original units. Each key’s signal path consists of special independent digital sound source and optronic audio gate with specific dynamic curve. This fully polyphonic sonic array gets mixed and goes into the timbre control, optronic master gate and high precision pedal-controlled VCA at the final stage. Other highlights include MIDI input, computer USB interface, highly reliable touch keyboard, self-calibration routine, etc. Built with love and by the best Russian military quality traditions :-)"
