Apply effects to loops already while recording (not only afterwards)
I have asked a similar question a few months ago, and I would love to get some specific clarifications about it (https://forum.grouptheloop.com/index.php?p=/discussion/comment/1233/#Comment_1233).
My biggest problem with GTL at the time being is that it applies effects to loops only after they are recorded, which makes the whole feature useless in my opinion (and I don't see the reasoning behind it).
For example, when a verse contains of 2x the same chord progression, I would record my guitar on the 1st one, and a bass line on the 2nd one. For that I need to change the FX on my guitar exactly between 1st and 2nd progression, so my guitar now sounds like a bass on the 2nd one. If GTL applied FX directly while recording, I could setup this upfront; now I have to somehow make it work manually using my MIDI foot controller (by assigning a control to the "Next/Previous effect" in my effects app, which is Tonebridge). But this needs very good timing and is prone to creating artefacts.
Any prediction on when (or if) GTL will change (or add) this behaviour? Or do you have another idea? I know that FX are applied to the master input directly while recording, so I don't see why this would be different. At least from a technical point of view it should be possible quite easily, right?

Hi @Ben,
Yep it would be a great feature. I eventually want to add an input mixer to GTL which would solve this for you. You would be able to add unique effect chains to each loop. Unfortunately this is a big job, might even have to rewrite the audio engine!
A simpler solution could be for GTL to load input effects presets via MIDI. However there would still be a gap/glitches while the effects load so you wouldn't be able to switch intruments instantly.
Thanks for explaining this a bit more thoroughly.
Maybe the glitches would not happen if two different instances of Tonebridge were running? Or I would simply use different AUv3 effects, so they both could run in parallel and no internal settings need to be switched of either one?
Yes that could work, you would need to use an input mixer such as AUM to run the effects in parallel.
Good to hear. I'm already using AUM for this (see https://forum.audiob.us/discussion/39702/two-inputs-mic-guitar-send-them-individually-or-combined-to-looping-app-and-change-it-using-midi#latest for more details), so I think my next quest is to create advanced MIDI inputs using my iRig BlueBoard.
For anyone reading along: I'm currently learning on how to tweak my BlueBoard which only has 4 foot controls to accept more complex inputs, e.g. double/triple tapping and sequences. You can find more information here:
I will probably buy the Mozaic Plugin Workshop app (https://apps.apple.com/us/app/mozaic-plugin-workshop/id1457962653) to script my own MIDI inputs/outputs. Its scripting language looks way less complicated than Midifire's (which is talked about in the topics above). I will keep you updated.
