After Later Audio bOSC CEM3340 Oscillator

AFTER LATER AUDIO BOSC

The After Later Audio bOSC is a triangle-core VCO that has a wide frequency range and four outputs. It uses the CEM3340 chip found in many classic synthesizers such as the SH-101 and Prophet-5.

bOSC can act as a VCO or LFO, set by a switch, with a frequency range from 80 second cycles to 40kHz, well above the range of human hearing. It tracks 1V/Oct over five octaves and has four outputs: triangle, sine, saw, and pulse. The pulse wave has pulse width modulation with attenuator. There is also linear FM with attenuator and a sync input, which can either be used for hard sync or soft sync, set by a jumper on the back of the module. The bOSC is a solid oscillator, equally suited for low frequency and audio range operations.
