Distorque has released version 0.9.2 beta of Plusdistortion, a VST plugin emulation of a MXR Distortion+.

Distorque Plusdistortion

I’ve been looking into VSTs recently as a way to emulate analog stompboxes. I’m actually a bit disappointed by how few effect emulations there are, especially with free VSTs. So, I pulled out an old copy of SynthEdit (from back when the free version allowed your VSTs to have backgrounds), and I’ve made an emulation of the MXR Distortion+. It took a bit of research, especially for emulating the diode clippers. Most diode models are iterative, which would be too time-consuming for a realtime effect. After some experimenting with functions, I ended up using Vout=arctan(6*Vin)/7 to simulate the whole diode clipping setup.

Here’s the structure of the whole effect: Input attenuator -> Input HPF -> Pickup simulation LPF -> Op amp gain -> Op amp HPF -> Op amp bandwidth LPF -> Op amp clipper -> Output HPF -> Output LPF -> Output attenuator -> Diode clipping emulation -> Volume

Plusdistortion is available as a free download for Windows (VST). Feedback on this beta version is appreciated.
