I bought Blue Cat after Plugin Boutique proposed it as a solution to dealing with multi-channel midi input for Live users (which does not support midi channels), the specific source software in question being Instacompser.
However, there is no way IMHO that Blue Cat could do what was implied. The product does not have any capabilities to route outgoing midi to different ports, and therefore it’s not a mechanism to use software such as Instacomposer in Live.
You can by default only route mixed audio to Live by hosting the VSTs in Blue Cat. {There is a capability to route audio to ‘aux’ channels, but that doesn’t help much.]
So you can’t use any of the Live facilities at all, other than using Live to record the audio stream. I don’t think Plugin Boutique’s video was very helpful with respect to Live users for solving the splitting of multi-channel midi.
I have tried Bome MIDI Translator Pro – Bome Software , but that is a bit fiddly to set up.
However, I have been working more with Cantabile (apparently pronounced Kan-tab-ee-lay ), as the free version is a great lightweight way to run Scaler without firing up a DAW; unlike Nanohost, it supports VST3’s. Here’s Scaler conected to DUNE 3
Cantabile Solo (I upgraded the other day) seems to be a hidden gem of midi capabilities. It handles multiple midi ports
You can route source and target channels with a variety of conditions
and apply filters to any routing
It also has more sophisticated facilities for managing things like sysex and so on.
As it’s graphical, it very easy to set up.
I’m exploring more and may put up a tutorial to cover a variety of situations with multi timbral devices.
