Fantastic (free) synths and how to use them: DiscoDSP OB-Xd | MusicRadar

musicradar.com

The DiscoDSP OB-Xd is a standout in the realm of free software synthesizers, offering a faithful emulation of the iconic Oberheim OB-X. Its strength lies in the substantial and characterful oscillators, alongside a range of unique control parameters that add depth and versatility. The OB-Xd captures the soul of its analogue predecessor, delivering warmth and quirkiness through sophisticated digital algorithms. While the interface might be overwhelming for beginners, the synth's rich presets and authenticity make it a valuable tool for both novice and seasoned musicians. The overall sentiment is positive, especially considering its zero cost for non-commercial use.

A hybrid Oberheim monster.

You can get it right now, for absolutely free. While the interface layout mimics that of an OB-Xa's or an OB-8, don't be mistaken - it does actually implement things that neither of these could achieve, as great as they are.

The filtered is sort of modeled after the SEM, out of all things. It has a mode knob that can morph the filter between a lowpass, notch, and highpass, with an option to switch the notch to a bandpass one. This is REALLY useful for sound design purposes, however with the synths I already own it doesn't quite stand out.

What does stand out, though, is the rather interesting implementation of the crossmodulation. The pitch is kept stable (meanwhile, on the Arturia OB-Xa emulation, the pitch drifts, which I think might be more accurate? I don't exactly own a real Oberheim synth with crossmod to cross-check with).

Just watch out as there's two distinct versions of this plugin, one older one that is VST2 (and AU i think) only and don't feature any kind of patch memory/total recall, and one newer one that has VST3 and skins that does have patch recall (but sounds notably different). Either way, get it.

Synthwave dreams in a plugin

OB-Xd is a true to the original emulation of the classic Oberheim OB-Xa. This plugin gets that sought after oberheim sound in your DAW for a steal of a price. From the microdetuning of oscillators, hundreds of classic patches to get you started and up to 24 voices of polyphony. Its a powerful and well made emulation and it sounds great.
