I confess I don't really understand the 'thru track' concept. It's confusing - you see it in the mixer but nothing is recorded on it?
I propose we have a 'user track' this can be an audio track or a MIDI track that can either record audio or MIDI, can load a VST, play it, record it, and see and edit the data. It's not too much to ask, pretty standard stuff.
the whole thing needs a redesign
Many MIDI capable devices have three MIDI ports
In - Out - Thru
'In' is what is received by the MIDI device
'Out' is what the MIDI device transmits
The 'Thru' is just a way of sharing what comes In with other devices, rather than terminating the connection. It
sends the In to somewhere else: the Thru - but only if a connected to another module is required.
However, the way the BiaB implements MIDI Thru is somewhat not really clear, and therefore confusing
I suggested some years a go a graphical map that displayed the connections and device names between the inputs, outputs, VST's and internal synths used, and connectivity of different ports. Unfortunately, it didn't get a guernsey.
