GCP Sending CC messages and Values

Post by tchopper »

<t>I know that is you setup an expression pedal that it can be setup to send a message via a specific cc message and then the expression pedal itself will transmit a cc value from 0-127 (depending on configuration/setup) - thereby using an expressing pedal takes advantage of both a cc # and cc value.<br/>
<br/>
My questions specifically relates to xmitting a single cc message via an instant access button. Can an IA button be configured to also send a VALUE along with the cc message, or is it limited to sending only an on/off (0/127) “value” with the cc message?<br/>
<br/>
I ask because I’m thinking of adding my podxt pro back into my rack. I know that I can program the GCP to switch effects on and off, but the Line 6 MIDI specs also allow for the changing of an effect by transmitting a value along with the cc message (for example, so that I could change a Line 6 delay from “analog delay” to “stereo delay” without needed to switch to a different preprogrammed patch)<br/>
<br/>
Thanks<br/>
<br/>

Looks like I should’ve performed a search first... my apologies. I’m guessing this is the answer?

Yep, that's the answer... Instant Access buttons send Data 0 or Data 127, nothing in-between.

A possible solution is to use something like the MIDI Solutions Event Processor to create a MIDI Map of an event to re-define it to suit your needs.
For instance, you could program the Map so when it sees Control Change 27 Data Value 0, it would translate that to be Control Change 27 with a Data Value of 3.

Probably a much faster route than holding out for a update to nearly 20 year old MIDI gear :lol:

Thanks John. That helps. I wasn’t aware that something like the Midi Solutions Event Processor http://www.midisolutions.com/prodevp.htm existed. Sweet.
