What will be the best way to channel switch and boost on this amp with the following midi specs out of the amp's manual? What mode will i need to be in? I plan to chain the amp via midi into the gcx

MIDI PRESET MEMORY:
The Legacy 3 will save the CHANNEL selection (1, 2, or 3), BOOST(on/off),
REVERB(on/off) and LED backlight color in a MIDI program location (1 thru 100).
The settings will be recalled when the same MIDI program number is received.
Volume, Drive and Tone level settings will not be saved.
To SAVE a MIDI program setting: First, set the amp features for saving.
1. Hold down the channel (1,2,or 3) button for the channel setting you wish to save.
2. Now press the other two channel buttons, and release all three at the same time.
The REVERB LED will be flashing.
3. From your MIDI controller, select (send) the MIDI program number you wish to save.
The REVERB LED will stop flashing, and normal operation is resumed.

First of all, you make no mention of what MIDI controller you intend to use, although the question about what mode you should be in implies you're using a Ground Control Pro.

Second, as stated on Page 3 of the Ground Control Pro manual, in the MIDI section, if you are using a GCX it should always be the first device connected to your Ground Control Pro, so if you are using a GCPro you do not want to "...chain the amp via midi into the gcx." You should connect your GCPro directly to your GCX and then connect the GCX MIDI Out to your Legacy. However, based on the information you've provided thus far, I don't know what function your GCX is serving, as you don't need one to do any of the tasks you're asking about.

The Legacy 3: MIDI Features section of the manual provides the Continuous Controller values for changing channels, turning the Reverb On or Off, and activating the boost feature. If you want to do all this with Instant Access buttons, you'll need to be in 4 Presets/Bank mode so you can assign each of these tasks to an IA Button. You can follow the Legacy instructions to program basic Presets into the 4 buttons on the bottom row, then use your IA buttons to change channels, etc.

Hey thanks for the reply. Here is more info. I use the GCX to loop pedals in and out.

1. Midi out of GCP to Pedal In on Gcx
2. Midi out of GCX to Midi In on Legacy 3 amp
3. Midi Thru on Legacy to Midi In on TC Electronic G Sharp
4. Device 1 in setup is the Legacy 3 on Midi channel 01
5. Device 2 in setup is TC Gsharp on Midi channel 02

6. I got the channels to switch on the Legacy just fine and stored them in presets, however when I move down to device to and select a patch on the Gsharp thru the GCP (which works fine), in edit mode after selecting the preset on the Legacy, if I don't keep the Gsharp on preset 01 it will not switch the channels on the Legacy. The minute I move the preset back to 01 on the Gsharp, it changes the channels just fine again.

What am I missing here? The GCP is talking to the Gsharp and the Legacy so i know i have the Midi daisy chain set up right.

From what you've described, it sounds like you are trying to change presets on your G-Sharp independently from your Legacy, which you cannot do. In each GCPro preset you create, you will need to save the desired Legacy channel AND the desired G-Sharp preset number, along with the channel switching parameters you've set up for your Instant Access buttons.

1. I'm in 10 preset mode
2. I press button 5 on GCP then hold down edit
3. The first device comes up as the Legacy and I set that to 01 which is clean ( channel gets switched)
4. I hit the bank down button and move to Gsharp and put that on 02 which is chorus ( I see the patch change to 02)
5. I scroll down to the GCX loops which I have to normal and turn off or select which ones I want
6. I bank down again and see the name then bank down
5. I then hit edit and save

Now when I go to button 6 where I previously had Legacy program on 02 (crunch) and Gsharp program on 01 it changes to crunch and Gsharp says 01. If I go now to button 5 on GCP which we just set up above, Gsharp goes to patch 02 but the Legacy does not change channels to 01 (clean). I go back in edit on button 5 and change just the Gsharp patch back to 01 and save. I then hit button 6 on GCP and it goes to crunch and Gsharp 01. When I hit button 5 now on GCP, the Legacy goes to channel 01 now like it should.

Is this what you are saying I cannot accomplish?

No. I'm sorry if I was a little nebulous, but what I meant was you cannot program the GCPro to change the presets of two separate MIDI devices independently using one preset for one device and a second preset for the next device. When you change to a new preset, all of your MIDI devices will change according to the parameters programmed into whatever new preset you've selected, providing you correctly followed the edit and save procedures. That being said, it certainly sounds like you've got the hang of editing and saving GCPro Presets. However...

If I understand your description correctly this time, when you edited GCPro Preset 5 as described above everything appeared to be working so you saved it. Afterwards you changed to Preset 6, and both the Legacy and G-Sharp responded as desired, but when you went back to Preset 5 the G-Sharp changed to the correct preset but the Legacy did not change to the desired channel.

Referring again to the Legacy 3: MIDI Features section of the Legacy manual, I think in addition to programming the GCPro you also have to prep the Legacy to save the MIDI program settings as well, as described in the To SAVE a MIDI program setting section. As I understand it, this is how you will get the Legacy to recognize Preset numbers it receives from the GCPro and change to the desired channel. Give this a shot and let us know if it works.

When you program the Legacy, try doing it while you are in the Edit mode of any Ground Control Pro preset. It is possible that the Legacy simply does not like the extra MIDI data intended for the G-Sharp while it is "learning" the Program Changes. The test here is to make the Ground Control Pro send only the Program Change on the selected device channel.

1. Go to any Ground Control Pro preset.
2. Go into the Edit Mode by pressing and holding the Edit button.
3. Select the device location for the Legacy.
4. On the Legacy, select the appropriate amp channel, boost and reverb settings you want and put the amp into its "learn" mode.
(Press-and-hold the amp channel button you want it to go to, then press the other two amp channel buttons and release all three at the same time.)
5. The Reverb LED should be flashing at this point.
6. On the Ground Control Pro, type in the Program Change number you want to use, even if the desired number is already displayed.
7. On the Legacy, the Reverb LED should stop flashing.
8. Fell free to repeat steps 4-7 for something basic like using Program Change 01,02, and 03 to select amp channel 1, 2, and 3. After programming the three channels of the amp you can then re-program your Ground Control Pro presets so they select the appropriate amp channel and see if that changed the behavior.

I hope that helps!

John,

Thanks and I have already tested with exactly as you have stated above. As odd as it seems, it will only change channels if the Gsharp is on patch 01, so basically I have 5, 6, & 7 programmed as Legacy clean(01), Legacy crunch(02), and dirty(03), but all with having to have the Gsharp on 01. The minute I put the Gsharp to any other preset it won't work back in performance mode. I spoke with your team member Ben a while ago for a good bit and he said I was doing it right maybe just reinitialize the GCP?

Do I need to have the Gsharp as the first device and go Midi Out to Midi in on the Legacy? It just don't make sense at this point.

I tried all possibilities at this point. Nothing works like it should when in "performance" mode, when in edit mode on a certain preset, midi is working fine on both devices and switching patches like it should, save it then try to go from another preset back to the one you just saved and it will only switch patches on the second device(the processor) and not the amp...

I'm sorry, but I have to respectfully disagree with John on this one.

The way I understand the Legacy manual, you don't need to have the GCPro in Edit mode when "programming" the Legacy, nor do I believe just typing in the program change number on the GCPro while in Edit mode will do the trick. By now we're all familiar with these steps from the Legacy manual:

To SAVE a MIDI program setting: First, set the amp features for saving.
1. Hold down the channel (1,2,or 3) button for the channel setting you wish to save.
2. Now press the other two channel buttons, and release all three at the same time.
The REVERB LED will be flashing.
3. From your MIDI controller, select (send) the MIDI program number you wish to save.
The REVERB LED will stop flashing, and normal operation is resumed.

The way I interpret this, you should be able to call up the desired Preset on the GCPro while in Performance mode, follow the above instructions, and in Step 3 you would simply select (step on) the same preset button on the GCPro a second time. I may be wrong, but the way I'm reading things, that is how the Legacy will get the preset number information when it (the Legacy) is in "Save" mode. Other than that, I'm more or less baffled.
