Free Custom Acoustic Guitar IRs in Helix Posted February 13, 2020 Figured it out... when I rendered my file in Reaper it was set for something I did previously and the file was only 17 sec long. I fixed it to about 95 sec and got the IRs! Dude, I have to say I'm impressed. This is so much easier than going the tone match EQ/Deconvolver route. I'm toying with the signal from my Sigma DM-4 with a K&K and a mic'd signal from a KSM141. The IR sounds great on my direct signal in Helix Native, really takes the honky-ness away and warms it up really nice. I also have the benefit of listening through some awesome Focal monitors that give a nice neutral sound. Well done sir, I have to say the music community owes you one!
