Acidlab Bombass 2 is an analog synthesizer with a circuit based on TB-303, but modified in many aspects. It offers 2 oscillators with sync, ring, frequency modulation, noise, sub-oscillator, audio input, as well as LFO with various waves, including Sample & Hold. A number of sockets allow you to integrate it with other analog synthesizers.
Bombass 2 has 2 analog oscillators with the following modes: square VCO, sawtooth VCO, mixing between VCO 1 and 2, and previously mentioned modulation options. You can also mute the VCO. In addition, it has a sub-oscillator and noise. The VCO can be modulated by LFO and envelopes. The LFO can be restarted with each received note. With it, you can also modulate the cutoff frequency of the filter.
By the way, about the filter: Bombass 2 has a classical resonant TB-303 filter, which offers a decay, a cutoff control, and even a frequency modulation filter.
