Ver. 8 / How to: change tempo, change instruments?

[Niki]

For sure, I've missed the infos...
Just to know... How can I:
A) change speed in the back-track?
B) change melodic instrument in the back-track?
Moreover, is it possible to implement a sort a 'slow down' at the end of the track?

Hi Gatto!

B)You find the tutorial here: https://irealpro.com/dwkb/change-the...ck-instrument/

You can't slow it down, ritardando is not available.
