Doepfer - SuperBooth 26 Demo Patch

video upload by Stromkult

"This patch is built around the A-128 Fixed Filter Bank, one of our classic designs. The filter bank is pinged by a short burst of noise shaped by the new A-142-5(1U) Dual Decay/LFO. Sometimes this module also receives a gate at the Voltage Controlled Loop input, which creates ratcheting-like sounds. The noise also runs through a bandpass filter, with the cutoff being modulated.

To get these sounds on the Fixed Filter Bank, feedback is essential. The short-noise input goes into a mixer, then from the mixer to the filter bank. The output of the filter bank goes into a multiplier; one path goes to the camera, while the other is amplified with the A-119-2 and returned to the mixer with inverted phase. And the whole thing is split and also runs through a BBD, which is why it has a bit of noise."
