bassemu~ is an object that simulates a transistor-based electronic synthesizer. This serves as a emulation of an analogue bass synth. It includes the obligatory filter, saw/rect/tri/sine waveform select, an extra hi-pass filter. You can also feed another signal to its left inlet, and filter that, either alone or mixed to the vco.
Also included is a small, messy gop abstraction to resemble a 16-step sequencer.
