How to set up MIDI Guitar 3 Hex with the BOSS GP-10 and Windows 11

I just picked up a used GP-10 and licenses for MIDI Guitar 3 and the Hex add on. I’m using this on a Windows 11 PC with a Godin guitar connected to the GP-10 via the 13 pin input and a USB output to my PC. I have a Focusrite Solo as an audio interface. I’ve tested Windows output from the Focusrite and that’s fine.

I’ve installed the most current GP-10 driver. I’ve tried the tuner on the GP-10 with the BOSS Tone Studio app and it detects the guitar and I can tune it.

I can use the GP-10 as a MIDI input source in Cantabile Performer output MIDI to Arturia Analog Labs and Pigments, with audio out to my Focusrite and through that to my guitar amp. So I know the GP-10 is working.

When I start up MIDI GUITAR 3 HEX it’s displaying ‘NO HEX INPUT!’ under MIDI GUITAR 3 HEX. Under Settings, Audio Interface I’ve designated GP-10 (Channel 1 default) as the Input Device and Focusrite USB ASIO (Channel 1+2 default) as the Output Device. There is no sound when I play the guitar. Also when I add the MIDI Guitar 3 plugin to Cantabile and send the GP-10 MIDI input to it and then MIDI out to Pigments there is no sound.

I should say that I’m primarily looking to use this with Synth plugins and would ultimately run everything under Cantabile Performer, but right now I’m just looking to get a sound using MIDI Guitar Hex. Any Sound!

Apologies for my naivity. If there’s documentation I should read I’d appreciate getting pointed to it. Any ideas how I can get this to work?

there should be an option other than ‘channel 1’. on other platforms it is usually 1-8.

sorry, i don’t have a gp-10 and don’t know what it presents to mg3hex. but i believe you’re very close to having it working.

I’ve gotten this working using input device: GP-10 and Channel 1…8 (HEX PICKUPS).

I get sound and I can use 3rd party plugins (Pigments, Audio Lab) on chain 1 however tracking isn’t very good. I get octave up ghost notes and when I release a note on the fret board the open string plays no matter how gently I release my finger from the fretted string. I’ve tried changing all sorts of settings on MIDI Guitar HEX (strike, pressure, cc74, release) but can’t get it working decently.

When I gently pluck an open low E string, multiple higher strings are displayed on the Seeboard keyboard display (and are sounding) even though I’m muting all but the low E string, so it’s not sympathetic vibration. II’ve tried both my ‘Made for Roland’ Strat and my Godin XTSA. I’m also wondering why when I turn up Chain 2 in the mixer I get a weird distorted sound even though I’ve removed all modules except Analog Lab V in Chain 1 (no modules in Chain 2 or 3). It’s almost as if there are native sounds from MIDI Guitar 3 playing along with the Analog Labs sounds unless I turn down all but chain1 in the mixer.

One other interesting note: when I run the ‘Log/Troubleshoot’ utility, it shows line after line of ‘DEDICATED INPUT DEVICE UNDERFLOW’. I’m thinking this might be significant but don’t know what to do.

I’ve heard that the developers monitor this forum. Sure hope I can get some help here!

Glad you got it working, I was just about to send you a screenshot of the Cantabile Audio Port setup.

It should not be that an empty chain is giving a distorted sound. Make sure that you don’t use a GP-10 patch with any modulation or FXs, or set the GP-10 USB Audio Mode to: “Re-Guitar/Amp II”.

double check the channel/string assignments. that behavior can occur if they are mismatched.
