Since 1.30 you can set the mixing levels of all tracks globally which solved a lot of “kit issues” for me:
Added a GLOBAL FX/MIX menu item in the SETTINGS menu. In the GLOBAL FX/MIX menu, you have the option to set the parameters on the DELAY, REVERB, COMPRESSOR, INTERNAL MIXER, and EXTERNAL MIXER parameter pages to be global (making any change to these parameters affect all patterns in the project and not only the active pattern).
An older trick makes you copy / paste “kits” to another pattern: Digitakt Unofficial Guide - #122 by obk
And you can export / import sounds to the sound pool and reimport those in patterns where you need them.
With a bit of planning and some structured working, all of this is more than enough “kit funtionality” for me.
