Split: H90 Insert Feedback

[brockstar]

Also while I’m at it and instead of making a new thread….  can we find a way to not make an empty insert feedback, ouch!!!!!

I accidently clicked on insert 2 which has nothing in it and it started feedbacking really loud!

Maybe something in globals where we completely eliminate insert 1 and 2 from the signal path so that something like that won’t happen, if that’s something possible!

I can only imagine someone doing that at a higher volume level on stage or practice and that would be even worse then I did here in my living room lol.

Can you explain your signal flow that caused this? Do you actually have I/O 4 connected?

[brockstar]

Right now I have a meris lvx pedal into insert 1 and my H90 out into fx loop of my line 6 helix. Any time you engage insert 2 which has nothing in it, it starts to feedback for some reason?

 

In 1 and out 1 of H90 going to line 6 helix fx loop

In 3 and out 3 of H90 has the meris lvx as an insert

exp 1 and 2 are being used as well for expression pedal and a ehx 3 footswitch

[joecozzi]

Did you notice how Insert 2 was routed when the feedback started? If there’s nothing connected to I/O 4, then I don’t know how that could have caused feedback in a serial signal flow. If anything, the chain was broken.

[brockstar]

It happens as soon as you put insert 2 into the path, feedbacks right away

[brockstar]

Ok i forgot insert 1 has to be on parallel path, then put insert 2 on in pre position and it starts feedbacking

[brockstar]

Did you happen to look into this more after my last post? Thanks! :]

[joecozzi]

Hi brockstar, tbh, I’m confused as to why you are experiencing feedback if you have nothing connected to I/O 4, which is where the second insert effect would live. If there is nothing there, the signal chain is broken. Something else is awry. Could be the routing in the Helix?

[brockstar]

I’ve had helix since 2016 and have never experienced this before with many pedals that have come and gone and I’ve used inside the fx loop and I also checked it just in case and nothing wrong on my end.

Did you happen to try my suggestion but do it with low volume just in case!

Put a pedal into insert 1 and move it to parallel path, then take insert 2 and move it to pre (in front) and see if it does it for you?

[joecozzi]

I can reproduce the issue. Investigating!

[brockstar]

Aha, glad it’s not just me then! 🙂 Thanks for looking into it. I feel that one is quite critical to get under control before someone blows their ear drums out on accident like me haha.

[brockstar]

P.S: it may be good idea to check and reverse the role as well. Put pedal in insert 2 and put it on parallel path and then try insert 1 which has nothing in it and put it in pre-position and see if you get same results when investigating! 🙂

I can also reproduce; we’re currently looking into this one at a high priority level.

[brockstar]

Thank you! 🙂

While we’re on the subject of this insert stuff. Is parallel path suppose to be louder in volume? I get a bit of a volume jump when moving my insert to parallel path compared to being in pre / mid / post, maybe that is normal or no?

Maybe this has something to do with the feedback issue as well or something to look into as well.

Try this:

Put a pedal in insert 1, turn insert 1 off, and also turn off preset A and preset B and now move the insert 1 block around between pre / parallel / mid / post and you’ll hear that parallel is a bit louder.

[joecozzi]

This is normal behavior. Keep in mind that when you engage a parallel signal path you’re splitting the dry signal as well, so there’s two copies of the signal present. This is why the H90 gives you a couple of options to tailor your signal flow levels: you can run algorithms in Kill dry and/or you can adjust the Inserts Mix, send and return levels.

Ok awesome, was just making sure 🙂 Thank you!
