Buchla 251e Phased Sequences

"Four identical sequences with slightly different tempos is easy with the Buchla 251e.

Two Studio H Dual Programmable Oscillators provide the four sound sources."

254e first explorations

"I've been beta testing this new, cool Buchla format 254e module from Doug CL (aka boobtube356). Thought I'd post these roughly shot videos, which were originally just for my personal archive, to show some of its possibilities. One of the main features of this module is that all these explorations can be saved and recalled using the 206 Preset Manager. Love this 254e!"

254e Pulses and Transposes

Published on Mar 5, 2016 boobtube356

"254e prototype test demonstrating pitch transpose and pulse processing. A sequence from the 250e is offset in the 254e, and the amount of offset is controlled by switching among three presets. Meanwhile, the 250e pulses are modulated in the 254e using a 281e LFO, and the pulses go straight to the 292e. The sound source is a 258v."

What song is this from or similar to? It reminds me of something but I can't place it.

Update: think I found it.

"Little patch thrown together to demonstrate a few things. Lower 250e running in continuous mode under v30.6 works well with stepped input from the 251e. Compare this to the cruddy timing in my Butcher Reverb vid. Many thanks to Darren for pushing this fix through."

259e Sequence V

Published on Oct 28, 2012 by boobtube356

This one kind of reminded me of The Doors LA Woman for some reason, and the intro sounds to LA Woman below reminded me of Buchla.

"Another spin on this concept, drawing on some of the discoveries last time. Mainly this is about using the 251e as a trigger source, with 281e modulated clock division, using the envelope outputs as the clock outputs, and the 266e FRV to modulate the decay.

Bassline = 259e
Elec piano = 285e with null signal input and FM from 259e (output volume set to max).
Lead thing = 259e soft sync. (still not happy with this, but had to get on with life and call it good enough)."

"Reconstruction of the second vid in this series. There were a few changes, but the result is close enough and simpler.

The key here is sending an irregular pulse to the 266e QRV section. The result selects stages in the 250e running in continuous mode. The irregular clock comes from a steady pulse to the 281e, with the decay amount determined by a 266e FRV. The trick is to use the envelope as the clock output instead of the pulse. This means the clock will always be on a regular time, but it may skip a few input pulses if the decay is still in progress due to a long decay time. By adjusting the decay fluctuation rate and decay offset, you have a lot of control over the density of the output. It can be mostly on, mostly off, or somewhere in between.

Another key here is to use the 255 as the envelope for the sound, based on the ALL output of the 250e. This means rapid changes will get emphasis. I found it best to use a very small nonzero rise setting on the 255 so that the levels would move around more gradually. However, this leads to a sloppy envelope. The fix is to use a 281e for the envelope instead, and use the 255 to control the level of it using the VCA in the 256e (or 254v). This gives you crisp envelopes with variable emphasis. Best of both.

Another key here (possibly too much in this vid) is the exploitation of the stage jitter in the 250e. In continuous mode, it is possible that the input stage selection voltage will land very close to the center between two stages. When this happens, the 250e toggles back and forth between the two stages. The rate of the toggle is usually fast, but sometimes it's a little slower. I found that the number of steps selected in the 266e QRV section affects the likelihood of the effect. It seems to happen at a setting of 7 or 13. A side trick here is to apply a small amount of slew to the stage selection voltage using the 255. This causes the 250e to issue two successive pulses, almost too quickly to hear, and only sometimes (depending on how far away the successive stages are), which causes the envelope in the 255 to boost more. It adds more variation to the emphasis on the 281e.

The trumpet sounds from my earlier vid in this series was confirmed to be the 259e, tracking mode, modulating the morph, hard sync, mem skew b at about 2 o'clock, just like I had claimed. I hit them here too, but decided to do something a little different this time instead, hitting something closer to the old buchlajazz version of this on my soundcloud channel.

I think this patch would benefit from a retuning, and maybe more tweaking, but the main aim was reconstruction and documentation. Some of the techniques here are broadly applicable."

"Percussion experiment using the 291e and 255. Then more crud added for fun. If you ever wondered what you can do with eight slew limiters, here you go.

Bass kick = 291e channel A fed back into itself (no external sound source).
Channels B&C processing noise from the 266e.
All three channels use the built-in 291e VCAs (292e not used).
255 supplies EG modulation, 250e supplies pulses.
291e ALL output goes straight to the 206e (only one mixer channel required).
Main sequence is the 259e v21 tracking mode, morph modulation.
261e + 285e does the standard plinkity plink at the end, taking unattenuated pitches from the QRV section of the 266e."
