I have had a lot of fun so far with this app. One thing I was thinking about was the beat repeat section. Loads of fun already but how about a few additional options. I think a really strong workflow would be the ability to ARP the sample sort of what you can do in the app Samplr.
Also maybe a mute all except the beat repeat section option. Say you were performing live and wanted to do a little solo or something with the beat repeat section, then you could click an option mute, and it would mute or pause the rest of the loops and you could play around with the beat repeat. Maybe mute would be good and you could bring back in say a four on the floor drum beat and slowly build the loop back up.
