Not being overly familiar with the features of your 2 amps I'd being taking a guess but.... Since your Diezel has MIDI you could setup up a preset (or presets) on a Ground Control Pro to send a MIDI program change messages to get the amp to change stored "programs". I'm not sure about how your Bogne...

Can we assume you are using a GCP/GCX setup? Are you using your two amps at the same time with different channel settings?

Hi John Yes I am using two separate guitars and switching back and forth (only one guitar can be active at any given time). One of the guitars is feeding a Roland VG-99, which connects into the returns of two loops (#5 & #6) (left & right stereo). The other guitar is going straight into a preamp whi...

Thanks for getting back John. The fact that the grounds are lifted on the "returns" does shed some light on the matter. This would be why the hum level would decrease considerably when I gripped the metal caps of the patch cords going into the return and output jacks. The return seeing ground (all b...

I just took delivery of a new GCX. I wanted to use an A/B setup so that I can switch between two different preamps. I have the preamps patched into the GCX as shown in "Example 1, Page 8" of the GCX manual. With the loop deactivated I get signal from preamp 1 no problem. When the loop is activated h...

Thanks for getting back. I believe that answers my question. I had been thinking I could connect a sequencer to the GCP's MIDI input to call up presets automatically. But also if the MIDI system timing messages are passed along to the other connected downstream effects such as delays that can be set...

Can anyone tell me if MIDI messages arriving at the MIDI in-port of the GCP are echoed at the MIDI out-port?

I haven't seen anything in the manual but I may have missed something.

Thanks
