Help needed setting up controlling synth with midi

[DigitalSoul1973]

Hi

So have literally just installed Ableton 10 today after using Maschine for a few months. I am trying to set it up so I can play external SH01A from Komplete Midi keyboard.

I am using NI Komplete Audio 6 as Audi interface and have an audio track set up from which I can play my synth. I have then added an External Instrument to a midi track which has the following settings.

Midi from: Konplete Kontrol A49 (I can see midi information is being received into the track)
Channel 1 - Same as my SH01A
Audio To: ? Not sure what to set this to, although no option makes a difference

Then in the External Instrument Settings:
Midi to: Komplete Kontrol Output (Komplete Audio Midi)
CH1
Audio From: SH01A (which is the label for the Audio interface in its connected to)

When I play note on midi keyboard I can see Midi Out light respond on Audio Interface. I also have midi out from audio interface to midi in ON SH01A.

If I play the SH01a directly then audio is coming into Ableton.

What am I doing wrong?

Many thanks

Stewart
