Mix IR with original signal?

[AeroUSA]

Hi,

 

I downloaded the Taylor IR's as I have a piezo pickup in my PRS guitar. The problem is that with this IR engaged the sound is too 'wet'. I tried using the mix control but all it does is lower the output volume. Is there a way to blend a little IR sound with the original signal?

Where do you have the level of the IR block set? If the mix control is lowering the volume, it might be that the level of the block is set too high.

 

The other thing you could is simply is create a split in the path and put the IR file on it's own path. That way you could mix the dry signal from the guitar with the IR using the split block.

Have you tried putting the IR in a split path? Try using an A/B split block and adjusting the mix of the signal routed to the dry path vs. the IR path. More specifically, create Path 1A to be your fully dry signal - no IR. Then place the IR where you want it in Path 1A and drag it down to create Path 1B. Change the split block to be an A/B Split and adjust the A/B signal levels. This way you can leave the IR itself at 100% mix.

Hi

 

The IR block level is at -18.0 dB. I thought about setting a separate path but I'd prefer it if the mix control works as expected.

The IR Mix does not work as expected. A user should be able to match 100% IR Level and 100% "non-IR" level and then use Mix with no volume changes. Try that using 100% Mix (100% IR) so that its volume is equal to the un-effected guitar level when the IR Block is bypassed. If levels are set to sound the same between 100% and bypassed (0%) IR, then the Mix control should provide a smooth blend at any setting. 

 

I can't use up a separate path for this as a workaround, as I'm using the Helix as a 4-channel mixer and all paths are taken.

 

I've reported it as a bug...

You can open a support ticket to report the bug.

 

Meantime..... There's a workaround.

Thanks guys, I reported it as a bug also...

Great tip thanks!!

Hi guys,

 

I posted a support ticket and they gave me the answer, seems to work great!

 

"Hi,

When you add an IR, it automatically has a -18db gain adjustment in the IR parameters. If you lower the mix percentage it would be like the volume is just dropping. Change the gain parameter to 0db if you're going to use the mix at anything but 100%.

Thanks,

Great to know, thanks for researching this! You may want to hit the "Mark Solved" button on your answer to get that lovely green color for an answered topic  :D

No, I don't believe that its solved. I got the exact same answer back from Line 6 when I reported this bug, but had to reply that setting the gain to 0 dB doesn't solve anything.

 

The gain setting (-18 db at default) adjusts the total gain for the mixed signal of dry + IR, and not just the IR. So, there is still no way to "balance" the dry signal and the IR signal so you can achieve a smooth mix at equal output levels. In this case, gain should allow the user to set the total gain of the 100% IR signal to match the level of 100% dry.

 

Try it .... there is no way I've found that will work correctly/smoothly unless you use a separate path to blend.

 

 

from the Helix manual: Mix "Blends the effected "wet" signal vs. the "dry" signal passed through the block. When set to 0%, the path bypasses the effect completely. When set to 100%, the entire path is fed through the effect, and no dry thru signal is heard.

No, not solved. I got the exact same answer back when I recorded this bug, but had to reply to them that this doesn't solve anything.

Ah, yes, I see your point, this remains a workaround rather than a fix as it does not work in certain scenarios. I stand corrected.
