Adding a 10k resistor across R131 flattens the initial "click" or "blip" sound, integrating the impact more smoothly into the body of the kick.
Manual pitch sweep or even sequenced via external CV if you use a vactrol. drumbrute mods
Using the 12 individual outputs (original DrumBrute) or 4 outputs (Impact) to route sounds through external pedals or DAW effects is the standard way to fix "dull" internal sounds. Adding a 10k resistor across R131 flattens the
The DrumBrute contains a 12dB/oct analog filter. While it can self-oscillate, its input gain is set conservatively to avoid distortion. The DrumBrute contains a 12dB/oct analog filter
The cymbal uses a bank of six square-wave oscillators. Find the master pitch resistor for the cymbal section (R400, 100k). Lift one leg and wire it to a SPDT switch. On one side, keep the stock resistor. On the other, wire a 500k potentiometer in series with a 10k resistor to ground. Then, take a gate output (e.g., Accent from the sequencer) and use it to trigger a simple transistor VCA that modulates the pitch pot’s wiper.
