"Initial encounter with the 1979 Compact Microsound Processor. Some fun now!! It is using the Pitch Shift/Time Stretcher mode.

Powerful DSP effects for Buchla systems.

The CMP is a powerful stereo effects processor which expands significantly on the original Clouds by Mutable Instruments. Dedicated controls for previously hidden functions, additional CV inputs, four memory banks for saving samples, and a digital CV attenuation schema make this one of the most unique audio processing modules in the Buchla ecosystem. Eight DSP modes are available which cover granular synthesis, pitch shifting, glitch-inspired audio looping, and spectral processing along with unique digital reverb and delay effects.

The CMP is a compact version of the Stereo Microsound Processor with the same basic functionality. An upgraded digital brain allows the CMP to support the "Superparasites" firmware which includes eight DSP algorithms. This firmware combines DSP code from the original Clouds by Mutable Instruments, Clouds Parasites by Matthias Puech, and two additional modes by Julius Kammerl. To change the DSP mode, press the TIME switch (upper left) for a few seconds and then press the switch to cycle through the list of algorithms below. The TIME LED will blink slowly to indicate the current algorithm, as shown below. The selection mode will automatically exit after a few seconds.

Mode 1 [●○○○]: Granular Processor
Mode 2 [○●○○]: Pitch Shifter / Time Stretcher
Mode 3 [○○●○]: Looping Delay
Mode 4 [○○○●]: Spectral Processor
Mode 5 [○●●●]: Spatial Reverb
Mode 6 [●○●●]: Resonator
Mode 7 [●●○●]: Beat Repeat / Loop Slicer
Mode 8 [●●●○]: Spectral Clouds
