OB-Xf is a continuation of the last open source version of OB-Xd by 2DaT and later discoDSP, bringing together several efforts going on in the audio space and combining them inside the Surge Synth Team infrastructure.

It is inspired by the venerable Oberheim OB-X.

Changelog:
Modern flexible resizing.
All data races and memory issues have been fixed, to the best of our knowledge.
Passes pluginval on strictness 10 for both AU & VST3 [LV2 not tested yet], with ThreadSanitizer & AddressSanitizer enabled.
