3 channel amp, switching channels via MIDI using HX Effects

[cgtrox]

Is it doable without using ANOTHER external box?

[Cody_smith]

If the amp has a midi input then probably. If it does not have a midi input then no. What is the amp?

It's a 50W EVH 5150 III head and it does have a MIDI jack. Just got the HX Effects yesterday and was just wondering if anyone else has done anything similar with a 3 channel amp

From the 5150III manual:

 

To set up and use MIDI for channel selection:
1. Press both channel SELECT buttons {E and I} simultaneously to
enter MIDI "Learning Mode." The current amp channel LED will
start to blink.
2. Send any desired Program Change message on any desired channel from your MIDI controller to the amp. The amp channel 1 LED
will start to blink unless you have previously assigned that Program
Change message to a different amp channel, in which case the previously assigned channel LED will start to blink.
3. Select the target amp channel (1, 2 or 3) using the channel SELECT
buttons {E or I}. All three amp channel LEDs will briefly illuminate 
to indicate if the amp channel assignment has been changed for
the Program Change message sent (if the amp channel assignment
has not changed, which would be the case when assigning amp
channel 1 to a Program Change message for the very first time, the
three amp channel LEDs will not all illuminate briefly because the
amp channel assignment has not changed from the default amp
channel 1 assignment).
If the Program Change message is currently assigned to amp channel 1 (default), you will have to press channel SELECT {E} twice to
select amp channel 2. If the Program Change message is currently
assigned to amp channel 2, you will have to press channel SELECT
{E} twice to select amp channel 1.
4. Repeat steps 2–3 for each channel on the amp, if desired. You can
also assign multiple Program Change messages to the same amp
channel for more flexibility.
You can use the Footswitch to temporarily change channels at any
time during MIDI set up and it will have no effect on saving the amp
channel assignments. All channel assignment changes must be
made using the front panel channel SELECT buttons {E and I}.
5. Once you are done setting up MIDI Program Changes, press both
channel SELECT buttons {E and I} simultaneously to exit "Learning
Mode." The amp is now set up to switch to the target channels
whenever the selected Program Change messages are sent on the
selected MIDI channel.
The default MIDI channel for the amp is channel 1. You can change
the MIDI channel for the amp by sending a Program Change message from any other desired MIDI channel during Learning Mode.
The amp will then only respond to Program Change messages and
Control Change messages on that new MIDI channel.

There ya go.

 

Go into Command Center, set the switches to the MIDI commands that you want to use, then follow the directions above.

 

Of course, you'll have to set the switches in Command Center on EVERY preset in which you require this functionality.

 

That's why a third box is a better idea, UNLESS the idea is to match a specific effects configuration for each channel, which just requires setting one Instant Command vs three stomps. Still have to do it for each preset, but easier and doesn't waste the stomp buttons.
