has anyone tried to use it during a live performance ?
Not something I have tried but I think Podiums engine could pull it off. I thnk only Ableton Live and possibly Phrazor have an engine smooth enough (gapless) to pull that off.
I have only used Phrazor as a sub host (VSTi) recently, so I cannot say for sure but Podium should be up to the task IMHO. 😉
I use actually podium , in choir practice , because i dont have pianist , it works very well , and with orchestral , i can make some nice arrangements 😀
