Blaster

Blaster is a plugin for making a decent happy hardcore off-beat bass as fast as possible. It has one sub oscillator that can morph between a saw and a square wave, and a main oscillator with up to 3 voices that can be detuned, PWM-ed, and/or sent through an aggressive chorus. The whole thing then goes through a simple drive control for distortion, and then a filter to remove high frequency buzzing.

The phase of the note played is consistent every time, so you don't need to worry about resampling to keep the phase consistent, and you can control the phase offset so that it fits in with your kick.

Blaster is free and open source software. You can find the source code here: https://codeberg.org/yeendigital/Blaster
