Duplicate Midi Ports

[richkeys88]

Hoping to use Gig Performer in anger for the first gig on saturday. All was going well until todays practice. Suddenly none of the program change messages sent from Songs were being recognised by keyboard (Yamaha CP73)

On investigation there seem to be duplicate midi ports. I discovered that in Actions if I chance the PC to CP73 -1 then it works.

My question is should I just untick the CP73 2? and why has this happened?

I don’t know if this is helpful or not, but looking at the manual there is some reference to there being second USB port on the keyboard. Did some MIDI setting on your keyboard change recently?

[richkeys88]

I don’t think that’s the issue. No settings have been changed on the Yamaha and it is only connected using the usb host.

[richkeys88]

But…what you have highlighted does rather imply there could be 2 usb ports. I assumed one port on usb and one port on 5 din midi

It seems that the CP73 generally uses multiple MIDI-ports on a USB-connection, which adress the internal tone generators and/or external devices - this should be set to the personal needs!

See manual page 25 and following:

VAW6080_CP88_owners_manual_En_E0.pdf

The German version of the manual goes a bit more into detail regarding MIDI-ports and states that those keyboards are able to use up to 8 MIDI-ports with 16 channels each!

See page 25 “MIDI-Kanäle und MIDI-Ports”:

MIDI-Daten werden einem von 16 Kanälen zugewiesen.
Dieses Instrument kann über diese 16 MIDI-Kanäle 16
verschiedene Parts gleichzeitig wiedergeben.
Die Einschränkung auf 16 Kanäle kann jedoch durch den
Einsatz weiterer MIDI-„Ports“ umgangen werden, von
denen jeder 16 Kanäle unterstützt. Ein einzelnes MIDI-
Kabel kann Daten auf bis zu 16 Kanälen gleichzeitig
übertragen, mit einer USB-Verbindung können jedoch
sehr viel mehr Daten übertragen werden – dank der
MIDI-Ports. Jeder MIDI-Port kann 16 Kanäle
verarbeiten, und die USB-Verbindung lässt bis zu 8 Ports
zu, wodurch Ihnen am Computer bis zu 128 Kanäle
(8 Ports x 16 Kanäle) zur Verfügung stehen.

means:

MIDI data is assigned to one of 16 channels.
This instrument can play 16 different parts simultaneously via these 16 MIDI channels.
However, the limitation to 16 channels can be circumvented by using additional MIDI ‘ports’ from each of which supports 16 channels.
A single MIDI cable can transmit data on up to 16 channels simultaneously, but with a USB connection much more data can be transmitted - thanks to the MIDI ports.
Each MIDI port can handle 16 channels and the USB connection allows up to 8 ports, giving you up to 128 channels (8 ports x 16 channels) on your computer.

So i guess you should take care of the MIDI-settings to be how you need them!
And then use the correct port within Gig Performer.
To make sure you won’t encounter some bad surprises, you should also make use of Gig Performer’s Rig Manager to organize and control the MIDI-assigments within GigPerformer and your rackspaces/widgets… it might be a bit of work and thinking at the beginning, but it’s definitively worth the effort, because if everything is done correctly, any changes (may they be done intentionally or forced by some erratic system behaviour) will be done within no time!

Thanks for your brilliant help and research.

For what it’s worth. my Yamaha MODX has 3 USB Midid ports displayed in GP.

[richkeys88]

How do you handle the 3 ports?

[Dave_bass5]

I just disable 2 and 3.

I’ve only (this week) started to use my MODX with GP, but i was aware of the 3 ports from before with DAW’s.

[richkeys88]

So I can disable unused ports and set the PC changes to the only remaining port. BUT when I pack up and set up again….new ports are created and not the one that has been previously used in GP.

Is this a Windows issue?

Windows can do these things.
