Variable midi clock / tempo change for live use
What apps can play back a prerecorded variable midi clock that i can then sync everything to, and is practical for live use?
i.e. i have songs that i need to add some looseness too... as well as some songs that have some gypsy style tempo increases.
...preferably with a song list, or controlled by program midi changes so can be used in a live set, when songs change?
