I'm trying to use Sigabort's MidiSynth software as a patch browser and librarian for my Novation Summit synth. (The software page is here
https://sigabort.co/midisynth.html.)
Works great in standalone mode but I'm having an issue opening as VST. When I load into track FX as VST I get the message
"Unable to open MIDI in & MIDI out. As Windows MIDI drivers are not multi-client, MIDISynth will not be able to connect if your DAW has the MIDI ports open at startup."
How can I best handle this when opening Reaper to allow MidiSynth to access to MIDI ports? I looked at the Reaper manual and couldn't find the answer. I am able to open MidiSynth in standalone mode, then open Reaper and things work pretty well. But there are some features of the software I can't use because it's not open as VST within Reaper. Any pointers would be much appreciated!
