V829 Bass Drum synthesizer raw prototype demo

Published on Apr 24, 2017 ktozjadlciastka

"V829 Bass Drum core was inspired by Vox Percussion King BD circuit. You can easily get drum sounds similar to those form Kraftwerks Autobahn. The sound is very rich in higher harmonics, as the waveforms are very far form sine.

Features:
- unperfect, asymmetrical waveform,
- included high pass filter to expose mid range frequencies,
- diode limiter circuit - primarily to limit the amplitude of somehow unpredictible T-network in drums core, but can be used for distortion also,
- decay of the bass drum sound can be extended with longer trigger pulse - without retriggering!
- 100% analog, very simple build with standard components values.

Controls:
- PITCH,
- DECAY,
- CUTOFF frequency of the HP filter,
- LEVEL of the output signal,
- LIMITER on/off.

I/O signals:
- TRIGGER - over 1 ms (longer pulse doesn't cause retriggering), 1-10V,
- OUTPUT.

Power supply:
- +/- 12V,
- below 10 mA from each rail."
