View Full Version : Problem between PC and GT-Pro
08-20-2006, 08:58 PM
I've tried everything I can think of but still can't get my GT-Pro to work with GT Editor. The little blue system light is on, USB advanced driver is selected, Output is set for USB DGL 100 Level and I have the USB drivers installed on my PC... Everytime I open GT-Pro Editor I get a message that says:
" It appears that the GT-Pro is unconnected or connected incorrectly. Please check the connections."
There is only one connection... the USB cable!
08-20-2006, 09:25 PM
maybe a bad usb cable?
08-20-2006, 09:34 PM
Well, the blue system light on means the Pro at least thinks it's connected, so we don't have to pursue the bad cable theory just yet....
In the Editor, under Setup->Setup MIDI Devices, what entries do you have for Input and Output? The one you'll want is obviously "GT Pro Control".
Has this ever worked? If not, this may mean the Editor wasn't installed correctly; it's pretty straightforward to re-install, so you might consider that. Note the instructions are pretty particular about the sequence of events....
Finally, have you checked the troubleshooting section of the manual? It's better than you might think....
We'll get it sorted out; I'll try to check the forum more frequently until we do....

Do you connect the gtpro to pci interface USB 2?
-disconnect gtpro usb cable from pc
-download from boss site the "clear file" so you can uninstall correctly your usb driver. open the file and uninstall!
-with gtpro usb cable disconnected, inert the gtpro cd software and install driver following the steps displayed on you monitor.
(the gpro must be connected switched off....switch on after connecting the usb cable.)
windows find new hardware, wait a minute and then switch off the gt pro without disconnect it from pc. Reboot windows.
when reboot is complete, switch on the gtpro.

Thanks for the replies fellas.
Ok, I uninstalled and reinstalled and now the GT-Pro and the Editor are talking... the only problem is there is no sound anywhere....
Here's my setup:
Guitar > GT-Pro > USB into PC > Cubase SX2
Soundcard is an M-Audio Delta 1010 > Macki HUI Daw Controller > monitors & headphones
* There is no sound even if I am not running through Cubase, so it's not one of the device manager settings in the program.
Should I have all of the midi in/out in the GT-Editor set to GT-Pro or should the M-Audio card be in there too (it's one of the options given)?
Any thoughts or ideas would be great.

I use Cubase SX at home and it works fine, but the total mix comes from the GT-pro, not from the soundcard of my PC. In Cubase I use the GT-Pro plugins in the device settings menu for input and output. And you should check USB Mix settings and Device Monitor settings on the Pro (page 90 in the manual). I have not yet managed to set the Cubase input channel to GT-pro AND the outputchannel to the soundcard?!

I've the same problem.... when arm track for record, there's a visible input in the db monitor but no sound came from the desktop monitor. I think that we can bypass/subdivide the gtpro signals and split it in 2 identical lines...one for cubase and another one to sound card. From cubase i can't set up the input and output using 2 different sound card at the same time, and also i can't set input to gtpro and output to "my sound card"...i think there's a sort of plugin or audio core that manage this kind of situations... My friend, with protools can record and listen all everytime, using a dedicated plug in. Windows is too complicated and surely not user friendly for managing device and priority process.
For now, i use usb digital out and the main out at the same time. Digital usb for recording in cubase and main out (to my "line in" sound card) for listen my gig. ....until we found the right settings...

Man this kinda sucks,
I've been tweaking the settings now for three days and still not a noodle when it comes to any audio through the USB - so basically what I have to do is use the usb for tweaking the patches (much easier than the hardware interface) but use a line out into my soundcard for actual recording. Kind of defeats the whole purpose of the digital connection, now it has to go out as audio then through an AD convertor and back to digital... Never had this problem with either the PODxt or GNX. Aty least the GT-Pro is producing nice tones!
What is annoying me the most is that I can't reamp through the usb now so there will be degradation of sound quality and a whole lot of hassle to send the clean dry signal in for reprocessing and back out wet (more AD conversion).
Its not a Cubase SX problem, because I still hear nothing when Cubase is not loaded... any more ideas?
Anyway, thanks for the replies and suggestions so far. I've tried them all so any other suggestions will be taken on board!

Well, for what it's worth, I can record digital audio from the Pro via USB, but I don't, and I'm much happier! Until someone convinces me otherwise, I think the S/PDIF digital out is superior to USB.....
[Yeah, I have done a little bit of research into S/PDIF, and I got the impression that from a certain perspective it's not that great, but it remains my choice.] There are two solid reasons for S/PDIF, but I'll keep them to myself -- maybe someday I'll write a book! :P
The good news is that you will still be getting digital audio out of the pro, and avoiding the D/A and A/D you incur by using line out...
08-22-2006, 05:21 PM
Cool, I'll check that out and let you know how I get on. Thanks for the reply!

Share with the group. :)

Com'on, I don't believe you have to write a book just to at least lists the reasons why you use it. Share with the group.
Okay, okay. You got it.
1) Latency -- in the sense of bus latency (and not the recording latency most of us encounter at one time or another): Unless I'm wrong, with USB your Pro's bits are competing with whatever else is on the USB bus.
1a) I think this latency is the biggest reason why you may not be able to direct-monitor while recording with USB; your mileage may vary, but I never did come up with a reasonable setting for the Audio Buffer Size in the BOSS GT-PRO's control panel widget. I know rcknrllmn had a simlar issue. With S/PDIF, this problem disappears.
2) I use SONAR (but this may also apply to other studio software), and I discovered that with the Pro's audio driver enabled (so that I could record via USB), a side-effect was a limit in the bit-depth and/or resolution I could use in my SONAR projects. By using S/PDIF, I get digital audio out of the Pro and am able to use 24-bit / 48Khz (or whatever my soundcard is capable of) in my projects.
...Well, whaddya know -- I did just write a book! :D

Thank you for sharing that aerial7. I'm glad I've stuck with SPDIF, even if out of convenience and wee bit of laziness :) Everything you stated makes perfect sense.
08-23-2006, 07:14 AM
@aerial7: What kind of soundcard do you use?
08-23-2006, 11:59 AM
When I first got my Boss GT-Pro, I discovered a USB driver problem (bug) with Windows XP. Basically Windows only allows so many USB midi device driver installations after which additional devices will not install correctly, even if you uninstall previous devices... I spent very many hours trying to make it work... no deal. There must be some way to correct this, possibly altering the registry, but I sure haven't found it.
I ended up using using the editor through the MIDI port instead of USB

@aerial7: What kind of soundcard do you use?
Audigy 2 (Platinum, I think); I know I just lost all credibility, but it's met my needs so far. Replacing it has just never been a priority in my GAS budget.... :D

If you ever find a way of fixing this, post it here please!!!! :)

No problem with my pc. I've Windows pro sp2 and all usb devices are connected on the same pci usb2 adapter. At the same time i use an mp3 player, an HDD and Gtpro all connected to my usb2 port.
All works fine.
Somethimes windows don't discover new hardware (in most cases, don't discover usb hardware)....
..in this case i move in control panel>system>hardware>device manager> select "controller USB"> up in the ACTION menu click on "discover modifications hardware (or something similar---- i've the Italian Version) and wait new hardware.

I uninstalled and reinstalled all USB connections, then connected the GT-Pro to a USB hub and still no luck. Also went into System through the Control panel and did a search/update for new hardware for USB... still nothing. Actually things have gotten worse now. The blue system light is on so the GT-Pro is connected but I only ever got the GT-Editor and GT-Pro to talk to each once. Ever since I rebooted the pc that time I keep getting the same error message every time I start GT-Editor (after first connecting the T-Pro) "GT-Pro is unconnected or connected incorrectly". Midi in and out in the Editor is all pointed toward the GT-Pro... as I said before, I have never had this problem with the PODxt or with the Digitech GNX series. I much prefer the tones from the GT-Pro but the only reason I bought it was to be able to record via USB for reamping and to be able to use the GT-Editor. Looks like I might have to get rid of it already... :cry:
I can't believe that BOSS/Roland havent addressed this issue, a number of posters above seem to have had the same problem so it must be a known issue. Also, it has nothing to do with the number of USB connections on my pc or the OS. I'm running a Dell Optiplex customised system with 11 USB ports and a USB hub with a further 6 connections.
I even tried midi through from the GT-Pro to the HUI COntroller to the pc, still no luck. I'll probably try using the SPDIF for a while but without being able to tweak the patches through te Editor I don't think I'll be keeping it in my rig. If anyone else has a last minute suggestion please let me know because I really want to make this work!!!
Thanks again for all your replies and suggestions.

I don't know if anyone mentioned this before (long trhead..) but have you tried another USB cable and connecting directly to the PC, without the USB-hub?
08-29-2006, 09:19 PM
Let's stick with a port on the PC, just to eliminate the hub as a variable. (I have a hub, but my Pro is direct-connected.)
My theory is that the device driver(s) are mangled -- perhaps Windows saw the device before the drivers were installed. So let's explore that....in Device Manager, under "Sound, video and game controllers", my working system has TWO relevant entries: "BOSS GT-PRO" and "BOSS GT-PRO MME"; double-clicking each to open Properties and going to the Driver tab both have Roland drivers, both are version 188.8.131.52 (but with very different dates). How does your system compare?
[Oh, for what it's worth, I see that same error you describe -- but only when I power the Pro off and then back on with the Editor running. (Re-starting the editor, of course, gets things working again....)]
09-04-2006, 05:31 PM
Almost gave up on getting this sorted, thanks for the reply. Right, I just checked the drivers and they are both 184.108.40.206 for GT-Pro and GT-Pro MME.
Also, I get the same problem when I have the usb connected straight to the pc port.... Also, I've tried a couple of different USB cables just to be sure and they all work fine on other gear.
09-05-2006, 05:18 PM
Okay, that's a start....For what it's worth, I just noticed something strange -- but apparently normal -- about the Pro drivers: My Pro was powered off, and Device Manager only showed the Pro MME driver until I powered the Pro on. At that point, the Device manager refreshed automatically, and then the "BOSS GT-PRO Driver" showed up. Does your system should also exhibit this behavior?
(I still suspect the eventual fix will be to uninstall the drivers and then re-install them, being careful that Windows actually uses the ROLAND drivers and not something else...)
09-06-2006, 06:35 AM
I managed to get the same problem!
Last week, for reasons that are no longer entirely clear to me, I had used the editor to reconfigure the transmit/receive MIDI channel on the Pro. Last night I tried starting the editor and got the same error message as you. No combination of re-starting the Pro and/or the Editor would make it work again.
Only when I went to the Pro and reset the MIDI transmit / receive channels and device id all back to 1, did things start working again -- and only AFTER I rebooted the PC and the Pro.
So, this is another thing to explore......
