Easiest setup to loop both guitar and mic separately?
I'm currently busking on the streets with an acoustic guitar and a mic, both connected to a small portable amp. I'm pretty new to looping, but I want to use it for future busking. I played around with Loopy HD for a while, but it doesn't feel to be optimised for live environments, as it doesn't seem to offer handling groups of loops, and also doesn't offer timed ways to start/stop the playback of loops.
GRL looks very promising to me. Before buying it though, I wuld l to get some feedback to the following question.
I'm using an iRig 2 to connect my guitar to my iPad. I didn't yet find a was though to also connect my microphone. As far as I understand, both a guitar and a mic are mono sources. The iRig 2 sadly seems to offer only a single mono input. After browsing around I seem to have to buy a better interface that allows me to connect two mono sources, which (to my understanding) then are combined to the left and the right channel of iOS' stereo input. In GTL I can then choose in the settings whether I want to record the left, the right, or both channels. Is this correct?
Some of the alternatives to my iRig 2, offering two inputs, seem to be Zoom U-24, Line 6 Sonic Port, iRig Pro Duo, and Behringet UCA222. Would they all suit my needs? Is there maybe some other alternative that I missed?
And can I easily change the setting for left/right/both recording while live looping? For example, sometimes I want to record only my voice for a loop, and sometimes only my guitar. As lomg as I'm only singing, or only playing guitar, I could simply set GTL to record left and right. But when I sing and play guitar at the same time, but only want to record my voice - can I easily change to this setting in GTL while live looping?
Thank you very much.
