Additionally, page 18 of the manual explains how to change the midi settings on the vermona and utilize midi learn. The sounds can each be set up to have there own individual midi channel but it is not necessary.
if you use the ‘chord’ function of digitakt you can have 1 trk with 4 drum sounds triggering per step , but it is annoying to edit and create quick patterns.
if you figure out where they are on chromatic keyboard it’ll make it easier to do hi hats/closed hi hats , as theyll choke each other anyway. (i think).
perhaps just group certain sounds if you do want to use less channels.
midi learn is a bit weird though , you cant do them all sequentially , but youll figure it out , i’m sure its on google/youtube somewhere.
