Tested with Windows XP, Ableton 8.2.
– Install Midi OX and Midi Yoke
– Run Midi OX and Ableton Live
– Disable Midi Yoke ports in Ableton > Preferences > Midi
– Create a midi track in Ableton with an external instrument
and set the external instrument for your synth (Midi port, Midi channel, Audio input)
– Create a second Midi Track in Ableton with the Ctrl vst plugin corresponding to your synth
Edit CTRL plugin
go to File > CTRL options
set the first menu to "Out To MIDI Yoke 1" (or midi yoke port of your choice)
set the midi channel below to the midi channel of your synth
– Group the two midi tracks in Ableton Live
Press Ctrl key on your keyboard and clic on each track then right clic and select "Group Tracks"
– Open Midi OX
Edit menu "Options" > MIDI Devices
Configure:
MIDI Inputs: clic on "In From MIDI Yoke 1" (or midi yoke port of your choice)
MIDI Outputs: clic on "Express 128: Port1" (midi port of your synth, in my example I use Motu midi express 128 interface)
If you want, you can uncheck "Automatically attach Inputs to Outputs during selection". Then you will have to route the input port to the output port in the next step.
Clic on "OK"
– In Midi OX go to menu View > Port routings
Verify that the Midi yoke port (Input Ports, MIDI Yoke 1 in our example) that you have configured is routed to the midi port of your synth (Output ports, Express 128: Port1 in our example).
If required, clic on the Input port, drag the wire and drop it on the output port.
It’s done.
Now you can play and listen to your synth with the external instrument in Ableton Live, and open the ctrl plugin to control your synth.
I hope it helps.
Note: this is required if your midi interface is not supported for multiclient operation in Ableton Live.
