Hello,
I've been trying to connect the GT-10 and a midi controller (Axiom 25) to control some paremeters with it. Until now with no success.

I've read the manual many times. but as I'm kinda new in this midi business I can't quite understand everything.

this are the steps I've been following so far:

1. connect midi controller MIDI OUT port to GT 10 MIDI IN port.
2. didn't change anything on settings, but checked omni mode is ON, Clock is set to AUTO, PC out is on and the RX and TX channels are both on number one, as for the controller, it's also configured on channel one.
3. went to a patch and foolow the steps described in the manual to configure manual parameter settings. Picked target to be patch master volume and source MIDI cc# 71 ( wich is some knob in the controller) activate the parameter manipulation with master button and write the changes.
4. nothing happens when I turn the knob.

Is there some way to Know if my Gt 10 is receiving the messages? so I can tell if the cable is broken or something?

is there another step to coonfigure? help please

This could be quite a complex matter depending on your understanding of midi controls and parameters.
There are two ways which an external midi controller can control the GT-10 internal parameters.
I also have an Edirol equivalent of your keyboard...

Some preliminary stuff first..
a.) The Midi port on the GT-10 only works if the USB cable is not plugged in.
b.) Your keyboard could possibly be the same as above if it has USB and Midi ports.
c.) You midi connection is correct Controller midi-out > GT-10 midi-in.

One way to control a GT-10 parameter is (in your case the Patch Master Level) to know which controller the keyboard is going to use (in your case you say CC#71) and use a GT-10 Assign on the Patch Master Level.
**********Assign 1***********
[Assign1: On/Off] = On
[Target] = MASTER: Patch Level
[Min] = 0
[Max] = 100
[Source] = CC#71 Midi Controller
[Source Mode ] = Moment
[Range Low] = 0
[Range High] = 127
(above listing from GT-10FxFloorBoard patch editor patch summary dialog)

this way would need to be saved for each patch you want to control, and the same control could do different things on each patch, you can also assign the same knob to control 8 different GT-10 parameters at one time/patch.

The second way to control a GT-10 parameter (if you keyboard supports this) is to use system exclusive messaging, for contolling the same Patch Master Level we would use the keyboard software for setting this..
F0 41 00 00 00 2F 12 60 00 0A 60 00 36 F7 = set Master Patch Level to "00".
F0 41 00 00 00 2F 12 = GT-10 data Header
60 00 0A 60 = Patch Master Level Address
00 = actual parameter data (in this control it ranges from 00h to 64h)
36 F7 = the data checksum and the sysx message footer (EOF)

so you would set the controller to use F0 41 00 00 00 2F 12 60 00 0A 60
then set the controller range 0h to 64h
and add checksum and F7 (the software may do this automatically).
This will control the GT-10 patch master level on any patch without having to progam anything in the GT-10.

Thanks a lot, man your pointers really help. Although my mistake was another, I didn't configured the sending channel on my controller. After coonfguring that, everything workd perfectly, as you said it, sometimes its kinda hard, thanks a lot
