# VCFQ water drops A slow pulse excites the VCFQ directly. The filter supplies the decaying sound; no oscillator is needed. ## Start here Lower the monitoring level before patching. These are documented patch designs, not claims of hardware audition. Unless this recipe uses the right Mix Pro for control voltage: center its DC offset, zero unused channels, and bring up only the cabled audio inputs. Connect Audio Interface MIX OUT to your normal monitoring chain. 1. GTS upper: about one cycle per second, with a visible rise and a longer fall. 2. VCFQ: HIGH/audio range, signal inputs empty; raise Q until each trigger rings, then tune FREQ. ## Cables 1. GTS XL upper END OUT → GTS XL upper TRIG IN. 2. GTS XL upper END OUT → VCFQ TRIG IN. 3. VCFQ BAND → Edelweiss right Mix Pro IN 1. 4. Edelweiss right Mix Pro OUT → Audio Interface AUX IN. ## Listen for Separated hollow plinks whose pitch and decay are set by the filter. ## Play it Move Q from dry clicks to overlapping decays while gradually slowing the clock. ## If it misbehaves A continuous tone means Q/feedback is too high; silence may mean LOW range or Q too low. ## Module references - https://serge-modular.com/docs/RandomSource_Serge_VCFQ.pdf
