Roland GR-1 Guitar Synth output volume is VERY low !

There is probably both a global volume and individual program violume as well. One or both may have reset to a lower level and need to be turned up. It's also possible that the general output has a setting for line level or instrument level, which may be software controlled. Take a look through your manual to find these settings and adjust to suit.If all else fails, contact Roland Customer Service at this link for help.

A Gk3 cannot be connected directly to an electric piano or synthesiser. The 23 pin DIN connector connects the GK3 / GUITAR to a Roland guitar synthesiser which produces the synth tones . This unit can be connected via midi cable to any external keyboard or synthesiser...to produce different or varied tones from the external synth ........provided the devices are able to communicate with each other...see the midi implementation charts for each device for information....

You cannot connect a Gk3 directly to an electric piano or synth. What you have to do is connect the 13 pin DIN connecting cable from the gk3 to the input on a Roland guitar synth unit like GR 20 or the GR 55 which supplies the desired instrument tones as required. The synth can be connected via 5 pin midi cable to an external synth to provide further tones...I personally have never used a keyboard to provide extra tones because I am a guitarist so only used synth modules and not keyboard ....remember also you need an amp or pa system to hear the sound output from the guitar synth module or external module.

Are the speakers hooked up? volumes up? Is the guitar using active pick-ups? if so, is the battery good? is any noise coming thru the amo?

This is a VERY low level output designed for headphones and will not drive a cab directly, you'll need an amp, take it to line in of an amp and all should be fine (REMEMBER This is designed to drive stereo headphones so is a TRS Right,Left,Screen. If you plug it into a mono input you will probably be shorting out one side of the peavey's output so get a splitter.

Check if headphone output is normal... sometimes the headphone jack switch fails and doesn't send to speakers when headphones are unplugged.

Hi, post on mvnation.com, they will be able to help.

Yep, you blew it up, all right.

The headphone jack in the laptop is a low-level OUTPUT which goes TO a set of headphones or the INPUT of an amplifier. You went the wrong way and fed a high-level signal (the guitar amplifier OUTPUT) INTO the laptop.

The electronics inside the laptop are not made to deal with the high level you fed in, so it's been damaged. Ever blow out a set of speakers with too high a volume? That's basically what has happened here.

To fix the problem and get your sound back would require a new system board.

Hi Nick,

The fuzz/white noise is a little confusing and it seems to be saying that you are recording something vs trying to record incorrectly and getting nothing at all. Anyway, despite that, I would try going over your recording steps first.

First off make sure your Hi-Z input is not set to the Hi-Z or guitar setting. It is possible your that MicroKorg is overloading the input and distorting. You should however have heard that in the headphones too, so I'm not so sure that's the problem. The next thing to check is to make sure your input is assigned to the track you expect to be recording on. (Press the input's button to check this. The select/record button over the track should flash).

Next make sure your track is armed for recording before you press 'play+record' (Record button above the track should light steady when recording).

Hope this helps.

Okay, maybe this is rude, but TOTALLY ignore Musicaldude's solution, if you haven't already found out the ugly way. Boosting the signal that goes into the KP will just make the input LED light up red and you'll hear digital clipping [gross] and eventually hit a ceiling of all-crappy-staticy-noise and no real guitar left. Having it in the FX loop, and the Headphone-out workaround are smart moves already, except the Headphone out adds noticeable noise/hum vs the usual outs. But to help close the gap between your guitar's volume and the miniKP's internal synths (and program 63 and 65's feedback noizes, which build up even louder than the synths) unplug one of the RCA plugs from the KP's OUTput, pick one, left or right, whichever. You'll notice this gives you a guitar volume boost. BUT its still not enough...the synths and 63 and 65's feedback are still speaker-blowingly loud. Check the manual, it says you can adjust the wet/dry volume by holding down Tempo and Preset A together, then turning the knob and picking 1 thru 99. Make sure you're on the synth setting you want to use already. Do this thing. Play the synth with your finger, while you lower the number with that knob. Stay around 50 if you've got the one RCA plug dangling, around 20 if both are in. Whatever you think matches your usual playing volume. When its where you like it, hold the A or B button (wherever you want to save this) down and click Hold, this will save it onto that preset button. Now from now on, NEVER use 63, 65, or the synths if you're on whatever preset you DIDN'T just save. i.e. If you chose preset B, from now on you can just tap preset B and it remembers your volume adjustment from before, voila, normal-volume touchpad synth. But go back to preset A for every other effect, or you'll barely be able to hear the FX. KORG should've given us more preset buttons to save onto. Godspeed. I've never seen this site before, but I have this pedal, and experienced the same b.s. myself. Now I'm down to one preset button and quick knob-turning. Whee.
