As always, an excellent piece of music, great work!
So I would like to open this track up and ask for help with a build up to the beat, some transitions, a slowing of the beat to go smoothly when the track slows etc etc.
Unfortunately there's no way yet to automate the tempo, hmm, guess I have to implemet that some day;)
To achieve a smoother tempo transition between the patterns, you one or mutliple transition patterns of lenght = 1. If you have already patterns with a lengh > 1, you can just copy the one you want to use for the transition to a new slot. Once done, use the 'copy individual pattern bars/positions' feature on the pattern set screen (long click on the pattern slot and choose 'copy individual pattern bars'). E.g. if you have a transition pattern of length = 4 you can split it into 4 patterns of length = 1. Once you created those 4 patterns, set the tempo something like transitionpattern1 = 160, transitionpattern2 = 150, transitionpattern3 = 140, transitionpattern4 = 130, and the next real pattern = 120.
If you still want it smother, you can create 8 transition patterns with length = 1 and laststep = 8, or even smother, 16 transition patterns with length = 1 and laststep = 4.
It's this what you're looking for?
