I would like to be able to freeze a track and its warp settings would match whatever you had originally warped your clips with. So if you have two clips on a track (one with Tones mode and another with Complex for example) your frozen track would be rendered and warped with the same settings (producing two frozen files I presume behind the scenes). Or at least the option to freeze the entire track at Tones mode.
Right now it freezes with Beats mode, which doesn't work well with musical instruments when you alter the tempo.
