I think a cool feature to be implemented was for ScratchLive to "calculate" & recommend a pitch for a song, based on the bpm's and overview analisis of both tracks.
For example, i had one song already playing with 128 BPM's... and its on 0.0% pitch. When i inserted a song with, lets say, 130 BPM, he would calculate and recommend a pitch or a range of pitch's for that new song...
