M3 not passing MIDI Thru?

Post by BZ »

I have a Yamaha S08 weighted action keyboard connected to the M3 via MIDI cable, and M3 responds to input from the S08 fine.

Next when I connect this setup to my Mac with a USB cable from M3;

1. Mac does not receive the notes played on the S08.
2. Mac does receive notes played on the M3 and plays back on the M3 fine.

Apparently, M3 is not passing S08's note data to my Mac. I do not see any MIDI thru toggles in Global mode.

How can I get M3 to pass external notes to my Mac?

Not too concerned with other controls from the external keyboard as I will use M3's joystick and control surface. I just want to MIDI record and edit music played on a weighted keyboard but using M3 sounds.

Thank you in advance for your input.

Interesting ... I don't have an answer for you unfortunately. I have similar problems with my M3. It likes to ignore midi from my Triton, but the PC hears both when I go direct to the PC, but like your situation - not when the M3 is in the loop.

I hope to find an answer to this, but I haven't had time to work on it. One thing - there is a PC program (there must be a MAC version as well) called Midi-Ox. It lets you see whats on the midi bus. I haven't had time to use it though.

Good luck and keep us posted if you find anything.

You are using the M3's midi Thru port right?

That should take the Yamaha midi signal and pass it to your Mac

No M3 here but ....

So you're hoping to have whatever you feed into the M3 MIDI IN socket appear on a virtual MIDI OUT on the Mac. IIRC the Radias (the only Korg instrument I have that does USB MIDI) is able to do this and achieves it by appearing as two separate virtual MIDI devices on the Mac, each with it's own IN and OUT. There are setting in Global mode that allow you to configure that behaviour. If you run up the Snoize Midi Monitor from http://www.snoize.com ... do you see the M3 appear as a pair of MIDI devices ? Maybe the M3 works similarly.

I looked at the M3 param guide briefly and didn't see anything that looked like commentary in the Radias manual that explains this kind of application.

From the M3 manual :

About the M3 and USB-MIDI driver ports

KEYBOARD port
Applications on your computer use this port to receive
MIDI messages from the M3 (data from the keyboard
and controllers).

SOUND port
Applications on your computer use this port to send
MIDI messages to the M3’s internal sound generator,
making it produce sound.
So there are two ports, but neither appears to route the physical MIDI IN back towards the host machine. Not from my reading of it at least. Midi Monitor should make it clear if it works or not ;-)
