Awesome!
I haven't seen such a unique concept visualization of audio sequencing since LSDJ and this is such a step above in terms of depth.
I am actually working on some tracks that include some recordings from Charlie with live drums and other instruments and I'm wondering if I can use these in a recording as long as I give credit on the release?
EDIT: Also, one feature that existed when I wrote this comment that seems to be changed in the standalone is that changing the "heart" settings effects the 1st tracks tempo. I really enjoyed that I could keep the initial track playing at the original tempo and then prepare the next track's tempo without changing the speed of the initial track.
But, in the end, Charlie is always learning and his brain is always changing so maybe this is the way he wanted to be :)
