Bongo CV comes equipped with two trigger inputs. A potentiometer allows you to crossfade between them. The sound varies depending on the level of incoming trigger signals. With just one input patched, the knob can be used as a tone control for treble attenuation. This behavior is not surprising, as the Bongo CV is basically a pinged filter. Accordingly, the sound shaping parameters are called frequency and resonance. The cutoff potentiometer is slightly erratic. Small changes sometimes have a huge impact on the module’s sound. The resonance leads the Bongo CV rather early into violent self-oscillation. Both sound shaping parameters feature CV inputs plus attenuators.
The filter is followed by a distortion circuit. It not only adds dirt to sounds, but also removes a lot of bass. – Very important for creating “real” bongos. – Without any distortion, the results are more reminiscent of bass drums or low toms.
The inputs can not only be fed with triggers, but audio signals as well. Patched like this, the Bongo CV acts as a filter. The sound qualities remain the same. Depending on the knobs’ positions, the sound is rough to brutal and more or less dirty.
