It is not implemented but was requested as new feature if possible (cannot retrieve the topic).
That would free the console and give great opportunities with the use of external plugin.
Well actually it work, and very well but it use 2 channels.
Just hook up a VST host PC or Mac software to the CQ (via USB), put a VST between any input and another output (set to digital in) and you can play.
Very low latency.
Maybe FPGA architecture can allow a digital insert as a future update, I don’t know.
But it worth nothing asking.
