Drumbrute Mods ✰

: You can flatten the "Impact" blip on the kick or reduce the overall pitch sweep range by wiring resistors across R121 or R131 to better integrate the transient into the sound.

Locate the snare’s noise envelope capacitor (C209 on older rev boards). This controls the decay time of the noise component. Stock value is 1µF. Replace with a 2.2µF or 4.7µF ceramic or film cap. Additionally, there is a resistor (R212, 47k) that feeds the noise into the filter. Solder a 100k trimpot in parallel to adjust the noise-to-tone ratio on the fly. drumbrute mods

Purpose: Provide standard 5-pin MIDI connectivity. Materials: MIDI DIN sockets, opto-isolator (for MIDI IN), 220–1k resistors, wiring. Steps: : You can flatten the "Impact" blip on

Route one of the drum voices (usually the Snare noise generator or the Cymbal mix) back into the Filter Cutoff Control Voltage input. Stock value is 1µF
