I've noticed some really strange things happen with Nanoloop and my CGBs. I've got two of them and the problems are affecting both. Like I've said before, I write everything using my GBA SP and that works fine and sounds fine. But I noticed a few nights ago when I used my copy of Nanoloop to show some friends a song I was working on, all of my sustained notes just wouldn't stay.
I tried with my other CGB and the same thing happened. But trying them in my DMG, those notes were back--sustaining better than ever. Can anyone shed some light on this? I've searched around and tried testing with LSDJ to see if the problems are there too, but I'm fairly sure they aren't.
