Let me help on GP10. First of all GP10 does not send MIDI CC OUT but gets MIDI CC IN so there’s no use of the Volume Pedal on board to become a fully fledged foot controller. The same applies to CTRL 3/4 (additional) or CTRL 1/2 (on board).
So the Breath control should use another MIDI path.
GP10 (depending on its USB configuration) can send 6+2 signals out. It’s up to you if you want to mute the GP10 own sounds or not so by using the foot pedal. You are not forced to go through MG3HEX to process your guitar, although up to a point MG3 is capable by hosting guitar plugins or using native cpabilities to process guitar.
I am not using this setup to play live so I use things differently according to the situation, make it practice or recording.
In general I would separate the Audio Signal (via USB) that is used to drive MIDI / MPE in MG3HEX from the guitar audio flow. Althouogh GP10 can act as an ‘audio card’ you need to test if that fits your use case. When I want MIDI only I let the USB Audio 6+2 and MG3HEX to do their magic, and record or practice with the VST result (synths). I record the GP10 guitar audio from a different audio card hooked to the desktop.I usually not record audio from GP10 USB. For a live situation it depends on what you want to achieve. Guitar / GR300 / Wave Synth from GP10 in parallel to MG3 Output? Then conceive Laptop + MG3 as synth device and GP10 + Guitar as your ‘keyboard’. I’d keep the Guitar Audio Lane separated (distorted sounds are better from GP10 than from digital VST, IMHO) from VSTs. However you can always use the laptop as the main sound processing and generator, with the help of MG3 and some guitar plugins. It’s all up to you.
The GP-10’s built-in pedal transmits MIDI CC#11 over USB by default. It can also function as a volume pedal for the ch. 1/2 USB signals if configured correctly.
none of the items you desire require mg3hex. you may be about to spend a lot of money unnecessarily.
also, in terms of control it seems like you want at least two expression pedals and two momentaries. this will necessitate a midi control interface, as none of boss units can accommodate four pedals.
lastly, running the pedals directly into your computer is a lot easier than trying to route them through a gp10/vg-mg800.
Well it’s true that at first i wouldn’t need the hex and will try to do without but i know that i will want to map isntruments per strings and do big chords with minor seconds which seem like hex is better for.
As for the midi in, well i guess i should have expected it that some additional equipment is necessary to get the additional controls. I was hoping that the GP 10 with the pedal and GK3 knob would already give me 2 ways to control and that i would need less other extra controls.
What do you mean by It can also function as a volume pedal for the ch. 1/2 USB signals if configured correctly ?
Can the buttons on the GP 10 serve as midi control for other things inside MG3 ?
Can the volume knob on GK3 be usefull ?
if you use a wah, then you probably want three exp pedals.
going back to your initial query, in terms of the ‘cheap’ option, ~$560 buys you a behringer UMC1820 and a subsix pickup (on sale now, with an add’l 10% off).
i don’t have any experience with either, but this path offers more flexibility and possibly better fidelity than any of the boss options.
I mean exactly what I wrote. If you want to also use USB 1/2 for audio you can put the volume pedal inline for those paths. Make sense?
Yes, but only for sending program changes.
It’s definitely useful as a volume knob. I don’t have a GP-10 anymore so I can’t confirm this but it’s possible to assign GK Vol to anything on the VG-99 and the SY-1000 — stands to reason that it would be the same on the GP-10. There’s a manual out there for the GP-10 — it might be worth reading it.
I was not expecting that at all, this pickup has 6 output from 6 cables so going in the audio interface in 6 input, then out USB into MG3 I guess, I havn’t seen anyone use this setup and am unsure MG3 would detect it but maybe ?. All the midi controls (expression pedal and other midi switches) could go into this aswell ?
Sorry but i’m not sure. I understood that the pedal for GP10 sends CC#11, I’m just discovering that different CC exist, i thought that anything can be mapped onto anything in MG3 to influence it. CC#11 is expression and seems close enough that it would be able to influence volume or other things i would want a pedal to (great).
As for the USB 1/2 use i’m confused, I don’t know what these are and why i would want to input the pedal on it.
Regarding GP-10’s buttons use
I’m not sure what that would mean as well, i see 4 buttons on GP10, ctrl 1, ctrl 2, up, down. What would it be possible to do with these ? Toggle on or off a certain instrument/fx in a patch ? Go up or down a patch ?
it may be easier to think of the midi control as separate from the audio input. it is often simpler to use a device which is expressly designed for that purpose.
The CC number is arbitrary unless you are targeting a device that is configured to specifically respond to it. Say for example you connect your GP-10 directly to Omnisphere 2, which is programmed by default to respond to CC#11 for volume control. I’m just letting you know that you have control available via the onboard expression pedal. MG3 will let you do what you want with it.
Sending a direct signal on Ch. 1/2 is useful if you want to introduce the dry modelled instruments from the GP-10 into a DAW-host environment. If it hasn’t occurred to you that it could be useful then it’s likely not applicable to your use case.
There are 4 buttons but only two of them transmit MIDI data. That data is limited to MIDI PCs that step through presets sequentially, either up or down. There are no other commands available. This could potentially be useful in MG3 if your only intention is to step through presets sequentially. Otherwise, it could be a hinderance.
I like where @kimyo is going as I’m quite interested in shifting to a breakout cable/multichannel interface setup at some point. But for now, the SY-1000 is on my desktop and doing just fine with MG3.
