One of my problems is that my recording-rig apparently isn't set up right (I'll have to fix that tomorrow, when I go into the studio/rehearsal space/music room). I can see what I record, and I can hear my playing when I export the .wav-file, but I can't get it to let me hear what's in the program, when I try to record. It's a bit hard to explain, actually. I have two individual cables going from amp to computer; the USB and a mini-jack, which lets me use the amp as a regular speaker, which makes it nicely easy to find songs and jam along to them. I've tried removing the mini-jack, and just run with the USB connection, and it doesn't work right. There are too many problems right now to list them all, but I'll find a set-up guide that covers how to use the Fender Mustang amp as an audio interface, follow that guide to the point, and see if things work. If it does, it's time to record and produce some music. If not, I'll keep trying to find out what's wrong until I fix the problems!

Add 1: I just checked, and as I would kinda expect, Fender has made a guide on how to use their Fender FUSE-compatible amps (Mustang and G-DEC) with Ableton. That should take the top off my problems...

Add 2: Well, my Recording-Rig is now properly set up. Sure, there's a 31,4 ms Overall Latency (15,1 ms Input Latency and 16,3 ms Output Latency), but that's something I'm willing to live with for now. At least I can get the Guitar-signal into Ableton, and hear what the Midi Tracks (Drums and Bass-line) and recorded Audio Tracks are recording (Rhythm Guitar and Lead Guitar). Now we'll see how it goes.
