Studio Electronics Boomstar Modular Mix4

Basic but indispensable through-hole synthesizers necessities designed (there's that word again) and assembled in-house. Augment efficiency and expressiveness starting with our handy R (Router) and ascending to its larger and more complex ATTENULAG companion—solidly entertaining to sleep-depriving voltage controlled switching, gliding, combining and amplitude limiting begins here. Multi-purpose heavy lifter. The attenuators reduce level, audio or CV, when switch is set to off. With the switch up the audio/signal passes through at full level. The inputs are linked together: patching into channel 1 drives both attenuators; patching into channel 2 breaks the link. Experimentation with key tracking to create alternative tunings, or interaction with audio inputs that don't afford attenuation—does good things. The two lag circuits provide a handy CV mult/hub for oscillator and filter tracking (perfect for CV-ing up our OSCILLATION module with its switchable one in/three out structure for both attenuation and slewing—x2) and are linked together: if you patch into channel 1 only, the outputs of both channels are driven (just like the attenuation circuit); patching into channel 2 breaks the link and they become two separate CV mult/lag circuits—envelopes look out.

Attenuation

ATTENUATE – Level reduction.
IN – Attenuation input.
OUT – Attenuation output.
OFF – Bypass is in up position
Lag
LAG TIME – Exponential slewing amount—still affectionately called glide in some quarters.
IN - Lag input.
OFF – Lag bypass.
OUT A – Lag output A.
OUT B – Lag output B.
OUT C – Lag output C.
