Buchla gmxe 700FM - Poly Firmware Experiments

video upload by verstaerker

"the 700FM voice Module got a new Firmware with a polyphonic mode. It overall sound a quite a bit different to the classic Mono Mode (wich is also available) .
I sequenced it with the Oxi One and controlled some parameters with the OXI E16.
The sounds gets a bit more cranked up by utilizing the 285e frequency shifter. The 251e sequencer controls some modulation of index and morphing between A&B sounds."

Poly Voice test _700 FM VOICE_with buchla 218

video upload by Gm Xe

"In the demo, the 218 is used as a MIDI keyboard, while still allowing simultaneous use of all its CV outputs and pulse outputs.

4-voice polyphonic architecture
Oscillator algorithm differs from the mono version; poly mode uses a waveform morphing approach similar to the 258 oscillator
Output now includes an internal VCA with built-in ADSR envelope, triggered via MIDI keyboard (velocity-sensitive by default)
UI updated with a dedicated ADSR page
UI updated with a Voice Mode page, allowing selection between:
Poly mode (with output compensation)
Mono bypass
Mono with ADSR
Added MIDI CC parameter control

Note: This is a test firmware version (not an official release). Feedback and bug reports are welcome.

video upload by Cfpp0

"Transposing a sequence on the Tokyo Tape Music Center 5 step sequencer using its own clock divider and the Verbos & Associates 243v pulse generator. Delay from the Peavey DDL-3 and reverb from the CXM 1978."

Exploration Situation of the Third Kind

video upload by Memetune Studio

"Taking the very sci-fi Buchla 200 out on another ride across the Solar Sythesystem™

Here's a close encounter with the 288 delay and 289 dual stereo FX with Lexicon-style algorithms - Nanu Nanu!"

Exploration Situation Two

video upload by Memetune Studio

"A more melodic exploration, still digging into those delays and reverbs, which is great to have onboard now with the dual Lexi-algos fitted to the 289 Defect Processor (thanks Maxlord)

I really love the way the 277 and 288 delays go all lo-fi and glitchy when CV'd"

“Innocuous Entity” 📡🎛️✨ Buchla / Késako / SoundFreak / Keen Association Modular system ✨

"Késako Player in loop mode with my own samples and pulse out, Synththomas 292, the Soundfreak modular set, and the Buchla 296e on even/odd mode processing 💫

The Buchla 246 took a break for this session, and no longer using a mixer module!👌🏽

Hope you enjoy it! 🤙🏼

"Here we are, the "MARF" aka Multiple Arbitrary Function Generator Model 248 in now in a reality in eurorack: all hail the 248t!

In this video I'm going to show you a bit of everything it can do (it can do a lot) but believe it or not I'm not going to go too deep. I'll try to go a bit deeper in some of the many rabbit hole of this things in future videos."

Exploration Situation

video upload by Memetune Studio

"Here I have set up an exploration situation, whereby I can mess about with various settings on the Buchla 200 while it's playing a semi-random patch

I'm using the 208 Easel module for initial sound generation, which goes to the 296 Spectral Processor, then out to two places: the even output goes to a mixer input, and the odd out goes to the 288 Time Domain Processor, then into mixer input 2. This goes out to the 289 Defect Processor top section, which has Maxlord's Lexi-like (224) reverb EPROM fitted. It's a great reverb! And you can CV various parameters. Joy!"

"Drum Kit:Alternative Bass Music (Sample Pack) https://akihikomatsumoto.sellfy.store...
Recordings: https://akihikomatsumoto.sellfy.store...
Don Buchla’s electronic instruments can be understood as musical tools and as environments for exploration. They allow performers to play in a physical and expressive way, yet they also invite a method of working that resembles research into the behavior of voltage and timbre.
Buchla did not follow the conventions of keyboard based instruments. Instead he created systems in which sound could be shaped through touch sensitive controls, complex modulation, and freely arranged signal paths. As a result, each patch becomes both a performance setup and a place to investigate how tones, noise sources, control voltages and modulation can interact within an electronic space."

Enjoy and take care!

Easel Sample Transformation

video upload by Todd Barton

"I'm always amazing how the Easel can transform & transmogrify a single sound. I begin with a single gong hit sample from the Morphagene going into Aux In on the Easel. Slowly gate that then move on the Balance Modulate it and finally bring in the Complex Oscillator for some thumps. Enjoy!
