I've been reading H9 posts and was wondering how to switch between settings in a live situation. If I would like to change different settings multiple times during a song, is it possible to do so? Would an outboard unit be required for switching between presets live vs scrolling through them? I am interested in purchasing a Timefactor for delay but to have other effects available would be great. I am curious how the small form factor functions in a live setting. I haven't found any questions in threads related to this. Sorry If I missed an explanation elsewhere. Thanks.
