In terms of VCV Rack: The best course of action would be to wrap it in a VST plugin. You either have to live with the occasional clicks'n'pops or use a really large ringbuffer, which will result in very bad I/O latencies. That being said, bridge plugins in general are a bad solution since it is virtually impossible to implement a low latency, glitch-free audio stream due to occasional OS "hickups". any heavy lifting in that callback is an absolute no-go). While working on my VST host, I came to the conclusion that there is no way around that kind of ringbuffer since the (ASIO) buffer-fill callback has to return ASAP or micro-underruns can (will) occur (i.e. I had to increase the total bridge latency to 4圆4=256 frames to reduce underruns to a minimum. ![]() I wonder if this in any way hints at an underlying difference between how Reason treats VSTs or if it's just a coding/optimisation thing? Įarlier this year I wrote one of those inter-process bridge plugins myself ("databridge") and from what I've witnessed, Reason apparently uses a ring buffer that pulls in multiple 64-frame chunks from a VST plugin. ![]() Unfortunately the new feature "Bridge" which allows audio from Rack to be piped into your DAW appears to have some issues.being Pops and Crackling.
