No problem to program only for the number of Loops you are currently using.

Good Luck!

I’d suggest using the Courtesy Outlet on the back of the Pedal Power 2+ for the Avalanche Run using its supplied power adapter. This will leave outputs 5 and 6 to power the Tensor and Blue Sky.

I hope that helps!

Welcome!
Here are some answers to your questions.

1. The Control Switcher will connect to the PX-8 via a MIDI Cable. MIDI Out of the PX-8+ to the MIDI In on the Control Switcher.

2. The Control Switcher won't take up any of the PX-8+ Loops. You will still have all eight PX-8+ Loops for effects. Adding the Control Switcher will add four more "loops" for controlling your amp.

3. Preset programming for the Control Switcher will be to recall a preset on the PX-8+, press the appropriate buttons on the Control Switcher for how you want the amp set for this preset, then store the changes on the Control Switcher. After that, every time you recall this PX-8+ preset it will also set the amp to the state you've saved on the Control Switcher.

Once you have this stuff in front of you you will need to do the following programming steps to the Control Switcher as shown in its manual. (Just be sure to use the Control Switcher manual that matches the unit you have... programming is different between the model with Red Buttons vs. the older model with Black Buttons.)
1. Set the Control Switcher to respond to MIDI Program Changes.
2. Set the Control Switcher to respond using MIDI Channel 1.

Let us know if you get stuck!

The Courtesy Outlet is rated for up to 200 Watts... the 18V Adapter you want to use is probably rated at less that 15Watts, so no problem at all!

I hope that helps!

The Commander will work with the PX-8 or PX-8+, and will be phantom powered via the MIDI Cable. The PX-8/PX-8+ can be added to this Pedal Switcher rig or it can replace the Pedal Switchers.

The only difference is that the preset save function will need to be performed on the PX-8/PX-8+ itself rather than using the Commander "Store" button, and the PX-8/PX-8+ will need to be programmed to respond to MIDI Program Changes on MIDI Channel 1.

I hope that helps!

I am kind of in similar situation as I cant figure this one out.

No cables need to be unplugged...

He is saying that he has found that the ES-8 has the ability to program up to 16 Control Change Messages with each preset. This then means that what I was saying in my original reply can be done.
To control a GCX properly, you will need to use eight of these Control Change messages. For each ES-8 preset you will need to program the Control Change message for each GCX Loop.
A GCX responds to Control Change 80 -87 for Loops 1 - 8 respectively... A Data Value of 0 turns a Loop OFF, and a Data Value of 127 Turns a Loop On. (GCX Defaults to MIDI Channel 16)
So if you wanted an ES-8 Preset to have only GC Loops 3 and 4 ON, but the rest of the Loops OFF you would need to program into the ES-8 the following Control Changes and Data Values:

MIDI CH16, CC80, Data 0 (Loop 1 Off)
MIDI CH16, CC81, Data 0 (Loop 2 Off)
MIDI CH16, CC82, Data 127 (Loop 3 ON)
MIDI CH16, CC83, Data 127 (Loop 4 ON)
MIDI CH16, CC84, Data 0 (Loop 5 Off)
MIDI CH16, CC85, Data 0 (Loop 6 Off)
MIDI CH16, CC86, Data 0 (Loop 7 Off)
MIDI CH16, CC87, Data 0 (Loop 8 Off)

Only by programming the state of every GCX Loop into every ES-8 Preset will you be able to ensure that the proper combination of GCX Loops comes up in every ES-8 preset.

I hope that helps!

I suppose your first step then is to look to the HX Stomp manual for "Block Bypass via MIDI" under the MIDI Section. This tells you how to get into the HX Stomp to either assign a Control Change message to a particular Block Bypass or to at least see which Control Change message might already be assigned to a Block Bypass.

This is the Control Change number you will assign to the Ground Control Pro Instant Access button you want to use to Bypass this Block. The HX Stomp defaults to MIDI Channel 1. So as an example, let's say you wanted to use Instant Access button #5 to bypass the Vintage Digital Block.
1. You would to go in to the HX Stomp and assign the block Vintage Digital to Bypass using "CC4"
2. You would then go to the Ground Control Pro and assign Instant Access button 5 to be MIDI Channel 1, and use Control Change 4.
(The actual CC number doesn't matter other than they need to match between the HX Stomp Block Bypass and the Ground Control Pro Instant Access button you wan to use for this Block.)
That's it except to repeat the steps for each Block you want to Bypass with buttons 5-8.

While I have not had any time with an HX Stomp, I have set this up on an HX Effects and it works exactly as expected.

I hope that helps!

I like that you don't have to worry about which output to use for power hogs like the EQD Avalanche Run. I know that the 4x4 would work, but it is a little nicer to just plug in a bunch of pedals and only have to worry about the total current draw.

Great Idea!

We showed off our prototype X8 at the NAMM show in January

2A Capacity, eight 9V Outputs, with any output conservatively rated for up to 500mA!

Before the world's Electronic Components supply chains went crazy, we were poised to launch this in May. But now, until things settle down a little, all I can say for sure is that isn't going to happen

I was able to pick up a second GCP and install the v2beta chip. so now I have 2 GCPs: GCP1 (v1.13) 4 Presets/bank and GCP2 (v2beta) all IA. I have two follow-up questions.

First, is there a replacement I can get for the led screen (the green led screen at the top of the unit)? on the new one I bought (GCP2) there are a few led segments that stay lit and sometimes interfere with being able to read some of the programming (e.g. sometimes a "4" looks like "6"). Not a huge problem as long as I pay attention, but mildly annoying...

Second - re: MIDI path and programming. I have the MIDI path as follows: GCP1 MIDI out> GCP2 Midi in. GCP2 MIDI out > GCX. GCP2 being phantom powered and GCP1 being powered via the wal-wart. I was trying to program last night patches on the GCP1 enabling certain IA switches on GCP2, but no IA switches on the GCP2 would save. I tried it with neither GCP being linked, as well as GCP1 as Link Master and GCP2 as Link Slave. Am I doing something wrong, or is it that you can only program the IA buttons on the Master unit and the All IA unit is just IA, with no programming?

Thanks again for your help.

Tom

EDIT:
I just occurred to me (may be obvious, but every now and then MIDI still scrambles my brain), even though the 2 GCPs are linked (via MIDI cable, not necessarily in linked mode), the All IA GCP still needs to be programmed/setup to indicate that GCX 1 is enabled and the other MIDI devices (and respective channels) down-chain still need to be programmed/identified within the All IA GCP - i.e., that information isn't passed through from GCP1 (4 preset/bank), correct? This may not solve my patch programming issue, but would be necessary in order for GCP2 (All IA) to effectively control either the GCX loops and/or MIDI device CC on/off messages, right?

That was fast!

About the display, I'd seriously doubt that a display segment remaining lit is the fault of the Display Element itself... that said, we would be glad to take a look at this Ground Control Pro for you to fix whatever is going on. Before we go that route, I do have to ask, did you have re-initialized the memory on this Ground Control Pro since you changed the firmware chip? It will very likely do funny stuff if you don't reset the memory.

About programming the IA buttons on the second Ground Control Pro... What exactly are you setting these buttons to do? If they are set to control GCX Loops then you shouldn't have to do anything on the IA Ground Control Pro other than to program the function of the buttons. If they are programmed where you are assigning the MIDI Channel and Control Change number then you will likely need to also set them as "Transmit with Preset". Let us know what these buttons should do and I should be able to help you better.
Either way, all preset programming in this setup will be on the Preset Ground Control Pro.

About your edit... You should not be enabling GCXs or defining any Devices on the IA mode Ground Control Pro (more accurately to say is that you cannot anyway since it won't even let you). You certainly shouldn't be setting either unit's Link modes as they are not intended to work together that way given the differing firmware. Leave them both set to Link = None. For that matter, if you are only controlling GCX loops, leave all settings under MIDI at their initialized defaults in the IA Mode unit.
Almost all MIDI data will actually be generated by your Preset Ground Control Pro and the IA Mode Ground Control Pro will simply set its LEDs to match the data as it passes thru. Of course the IA Mode Ground Control Pro will be the message source when you actually press one of its buttons, or if you are setting its buttons to Transmit with Preset.

Sorry for the delayed reply!

Your Ground control Pro is working properly... you just need to program the proper state of the Instant Access LEDs for each preset.

Here is how:
1. Call up the Ground Control Pro preset you want to edit.
2. Press any of the Instant Access buttons that should be active for this preset.
3. Press and hold the Edit button then release it once the screen changes.
4. Press the Edit button then the Yes button to save the state of the Instant Access LEDs with the preset.

Let us know if you run into any troubles!
