Roland MKS 50 as external device issue

[Kid Blast]

I am running Ableton Live 9.1.8 on a Macbook Pro with OS X 10.9.5, 2.8GHz and 16GB ram.

My MIDI chain is as follows:-

• MOTU out>Komplete Kontrol S61 kbd in
• Komplete Kontrol S61 kbd out>TR8 in
• TR8out>TB3 in
• TB3 out>midi merge 1 in A
• PG300>midi merge 1 in B
• Midi merge 1 out AB 1>Roland MKS50 in
• Roland MKS50 out>MOTU in

I have the MKS50 set up as an external device with the audio running out of it into the MOTU Ultralite.

The Komplete Kontrol S61 kbd transmits midi to and from Ableton Live fine, but it doesn’t seem to transmit it to the MKS50. Neither does the TR8. However the TB3 does.

Is there something I am missing here, which would make the keyboard transmit midi to the MKS50?

Set the midi out's of your gear to act as midi thru's.

No problem. You're welcome. I love looking through instruction manuals of gear I don't own to help people out.
