Erica Synths DIY Bassline is a fully analog complete synth voice module for ultimate acid basslines! This module features a highly stable AS3340-based VCO with Saw, Square & Triangle waves, as well as a unique transistor based sub oscillator circuit that provides a Square wave one octave below the main output. Bassline has a voltage controlled filter inspired by the Erica Synths Acidbox. The VCF has it’s own dedicated decay envelope generator, and you can switch between LP and BP mode. There’s an internal VCA also with its own Decay envelope and unique to the DIY Bassline is a drive control for thickening up and saturating the sound. There is an Accent input for providing expression – when this input is patched both the VCF and VCA will be pushed further open. Bassline also features an external FM input with dedicated attenuator and dedicated outputs for the Triangle and Square waves alongside the main output.
