XV-5050 Implementation Questions

Post by mpbman »

I am a guitarist that uses the XV5050 as a General Sound Module being driven by my Roland GR33 Guitar Synth in a live performance setting. At times I want the one or the other muted and occasionally both. I know how to "lick this" (pun intended) on my GR33. Is there a patch on the XV5050 that has no output? Or is there a MIDI command that I can send from my foot controller? I am a MIDI fledgling, but an experienced electronics tech and programmer. Any assistance or guidance would be appreciated... Thanks!

There are a few ways to do this, but the easiest is to send a Continious Controller (CC) message to the XV on the Midi channel/s you are using.

You need to turn off the volume of the XV, but to turn it back on you need to send a CC vol message that has the same value as you had before.

IF you can cope with hexadecimal (0x) the CC message is 0xB0 and you add the channel to it (0 to F)
If you are sending notes on channel 1 and the current setting of the CC volume is 110 on Channel 1
0xB0 7 0 turns the vol off
0xB0 7 110 turns the vol back to the same level.

Channel 3 original vol 96
0xB2 7 0 turns the vol off
0xB2 7 96 turns the vol back to the same level.


This should work for most synths not only the XV
Post again if you want to go a different way.
