Buchla Tiptop 264t | Buchla 200 Series | Episode 14 | Quad Sample and Hold / Polyphonic Adaptor


video upload by Cinematic Laboratory

"The original Buchla 264 is a very rare module, released in the 1970's. So it's important to realize it's a very primitive way of adding polyphony to a modular system. It's not that different from an early analog polysynth, where voice cards were used to activate two or more voices from a keyboard 'switch'. This is another fine example of doing easy things the hardest way possible, so there should be some reward in it. Apart from the polyphonic switching mechanism - you'd need four VCO's, four envelopes and four VCA's to switch between. I'll start with four Plaits, which can trigger their own internal LPG while distributing Marbles CV/GATE between them.

Then I used the Buchla LEM 218 keyboard to try and make chords. It didn't work so well, because the 264T is too slow picking the right voltage for the right key-down event. The 218 already outputs quantized notes in the 12-TET scale, so how hard could it possibly be to 'sample' the voltage from the played key and hold it? On the original Buchla 264, people used a gate lag (with the 281 envelope generator), to sample the voltage first, and trigger the hold with an end of cycle, just a few milliseconds later. Fortutnately, the 264 also has track and hold. In this mode, it can simply track the keys from the 218 keyboard, and hold it on key down. Works like a charm!

Regardless, this old-school analog polyphony is a lot of work and requires either a lot of modules, or specialized quad versions of your basic VCO, VCA and Envelope Generator. However, the module provides lots of cool resources you can use on a simpler setup, and results may be even cooler than trying to create polyphony. For instance, the polyphonic adaptor can double as a clock divider, which is missing from the current Buchla/TTA 200 series. It's super useful to clock a delay or sparse event. When combined with the 242 pulser, you could use a 11-step sequence, and pick every 2nd, 3rd or 4th event, creating all kinds of odd variations without changing the 'pins'.

Then there's ART, which is a new digital protocol for tuning a VCO, and sending quantized note and gate information. This requires an ART capable VCO like the 259T. While it's tempting to use two of those, it's much more fun to just use the principal VCO in ART mode, and use the modulation VCO in standard mode. Your voice will be in tune with other sources, but you'd still be able to create some new textures and leads. Quantized notes will steal some of the Buchla magic, so this is a best of both worlds. So if you're not pursuing polyphony (which isn't unwise), the 264 is a great source for stepped random voltages, divisions and quantized notes. Highly recommended for all you generative music lovers."

Ambient w/ Nord Lead, OP-1 field | As long as 2025-04-19 by atnr


video upload by atnr

"A piece created with the ‪@NordKeyboards‬ Nord Lead and ‪@teenageengineering‬ OP‑1 field—ambient music where simple drones dissolve into radio noise.

Nord Lead: I play a slow‑attack pad, routing the output through ‪@gfisys‬ SPECULAR TEMPUS for reverb and delay.

OP‑1 field: Connected to ‪@ChaseBlissAudio‬ LOSSY and GENERATION LOSS MK II while performing. Midway, I feed in a radio signal, shaping the noise in LOSSY.

The bell sounds were recorded with a RØDE NT1-A."
