tagmusenmagnus1 Posted January 3, 2016 Share Posted January 3, 2016 Thank you for you help on this subject - I see that I must find an aura for this purpose. There should not be any problem in using an IR that is longer than 2048 (or 1024) ? f.ex. my Computer tells me that the Wellknown Taylor IRs are 48kHz and have a duration of .029 sec that makes a sample-count of approximately 1400 which doesnt fit at all, but helix doesnt complain even though i am quite shure I loaded it as a 2048 in Helix' menu. Do you know anything about this? Or do we need a Line6 guy to step in ? Quote Link to comment Share on other sites More sharing options...
tagmusenmagnus1 Posted January 3, 2016 Share Posted January 3, 2016 Okay, the manual states that it crops all IR to 2048, if they are larger, but you would not rely on Helix for the cropping ? Of why are you concerned of the fade and so on - Just to be extra extra safe, or ? Quote Link to comment Share on other sites More sharing options...
amsdenj Posted January 4, 2016 Author Share Posted January 4, 2016 I've been creating the IRs specifically for Helix, using 48 kHz and 16 bit, and ensuring the IR is trimmed and cropped to 2048 samples with a short fade at the end. Most acoustic instrument impulse responses are likely to be pretty short, not like the long delays in a cathedral. So 2048 samples should be more than enough.

tagmusenmagnus1 Posted January 4, 2016 Share Posted January 4, 2016 Aah... Shure. Didn't think about it in that way. That makes totally sense! Thanks again :) Quote Link to comment Share on other sites More sharing options...

More to come. +1 Amsdenj you have consistently made the most substantial contributions to this forum for using the Helix with an acoustic guitar. Thanks for all your great work! I hope L6 picks up your banner and adds some IRs, amps, effects, and presets of their own specifically geared to the acoustic guitar.
