Orangey-Brown Accumulation (Buchla 100)

video upload by Memetune Studio

"This is a live performance on an original Buchla 100 from the late 1960s, using the Concrete Box™ , and TX-6 mixer

The patch uses 3 loopers and 2 delays, plus a very old Dynacord VRS23 reverb (which is adding some slightly woozy pitch-bendy-ness to the reverb)

The Buchla has a really basic patch - just one Sine-Saw VCO into the Sharp Cutoff Filter (Lowpass section). There's some cutoff mod from the keyboard capacitance voltage (which is why I'm wiggling my fingers in a rather silly-looking way)

The vintage Buchla 100 sounds so natural, rich and organic, I love it - almost like an acoustic instrument - a brassy, beautiful tone from the saw waves

Also, there's a second VCO (square) going into the HPF section of the Sharp Cutoff Filter (which is independent from the lowpass section in this mode) for the low drones

It builds up a bit like the many fallen leaves which have accumulated upon the now wintery lawn I am gazing upon"
