The compact bOSC from After Later Audio is an analog oscillator with an assertive sound. The powerful oscillator, whose core is a discrete Curtis IC CEM3340 chip, delivers sawtooth, triangle, sine and square with pulse width modulation. Incidentally, this is the same chip that was used in some Roland classics (e.g. SH-101). There are separate CV inputs for FM and pulse width modulation. Optionally bOSC can also work as a VC-LFO with reset, a rear panel jumper selects the lowest frequency range between 8 or 80 seconds.
