I'm just catching up and reading post #7.
 
I'm stumped.
 
It seems like the symptoms that I have heard amp designers call enharmonic feedback. (I never figured out why it's called enharmonic in this context)
 
I admit I'm stumped... but I'd try flipping the polarity switch on your track just to see what happens... not as a fix but as a search for a clue.
 
 
 
I'm assuming you have done a reboot and full power cycle (pull the plug) on the Quad Capture just in case it's just a simple hangup in the drivers.
 
Did I say I am stumped? :-)
 
Good luck.
 
best regards,
mike

Hi js516, Our replies crossed in the post, so to speak [:).

That happens a lot with me. Takes eons to type in a post on a smart phone. Lol

Maybe you have a fault in the ground or shielding and the electronics of the quad is picking up the monitors. Have you tried setting up windows to use the quad as its audio in and out to eliminate sonar? You can use either the windows mixer or the input test on the sound set up panel to monitor the input of the quad.

Does tweaking the gate at the top of GR5 help with the feedback?
 
I tried out 'NoAmp' at the weekend, which is a freebie emulation of Tech21's GT-2 stomp box.  I had all the inputs to it pulled all the way down but it still managed to completely shatter the Sunday morning peace (and my eardrums) :-D  I needed to put a gate plugin in the FX chain before it to calm the mad thing down.
 
The drums and bass thing has me stumped, those signals shouldn't be going anywhere near the guitar's channel??

 sorry if I didn't read every post here  :)
I would unplug every cord, wire, usb, exc from my unit.
power down / up (re-boot)
then start from scratch.
only pluging in your guitar cord for a test.
 
your new test is done using the default cakewalk template?
and your not using a track template ?
this rules out a possible problem you could have saved in a template.

@ Mike, I'm glad it's not just me that's stumped LOL. I'll try the polarity flip. I doubt if I'll get chance tonight because I'm working late.
 
@ js516, I'm seeing all you are saying and I can't answer you properly yet. I need to get my head under the bonnet, sort of, and tweak some more. I'm hoping it is not a fault that has since developed in my QUAD-CAPTURE because I really like that thing, with me now being laptop based. I'm sure the Q-C is okay and I'm keeping my fingers crossed.
 
@ ston, yeah, I noticed that (tweaking the gate level), but as soon as an incoming signal exceeds the gate level then all hell breaks loose again.
 
@ Chucke, thanks for your reply dood. Each test was done a day apart so yes, a power down, unplugging etc. was done between each project. I generally always use a blank Cakewalk template and add audio/MIDI tracks and busses myself as required.
 
 
I'll keep reading and playing, as soon as I can get back into my "studio." It has to be something simple and I am hoping that what I am experiencing is not default behaviour...
 
If I solve it in the meantime, rest assured, I will return with details. In the meantime, I will keep on checking back here for any revelations

I have no idea what the problem could be but wanted pop in and say hi to my old buddy synkro.
 
Howdy. Hope you've been well. ;-)

Hiya Beep 
 
I'm not bad at all thanks... I've been playing my guitar quite a bit actually and got me segs back on me finger tips LOL.
 
How's you?

I am glad to hear it and hope the leg has healed up nice and good. It is crazy time here in Beepsterville but that is par for the course. I'm still interested in a collab if you are but there is chaos that needs to be tamed at the moment so perhaps this winter. Cheers.

I created a new blank project,
I added a new single audio track,
I set the input to the left side of my Q-C,
I added an instance of GR5 to the effects bin,
I selected "God's Love,"
I turned on Input Echo,
Without anything connected to the Q-C input or having my headphones connected the meters hit the roof if I turned up the input level on the Q-C.
And turning up the headphone volume exacerbates the problem.
 
I also tried the same with an instance of TH2 added and selection a high distortion patch.

 
Maybe I missed it, but does this still happen if you have no FX in the bin?
 
 

Ah, Beep... leg's sort of up and down, which is damned typical for a leg LOL. I just have to keep taking the pills

That is a very good question and I really think that it does happen but it is hardly discernible. Then when a high gain effect gets put in it makes the issue really stand out.
 
I'm going to have another play while I've got thirty minutes spare...
