I thing I'm missing from ks is the arp collection, like doubles for ex, or arps with rests. I feel the KSP is pretty poor on that topic
1 way to be better than KS would be to record some custom arps, maybe something like yamaha modx but more simple, or something like matrixbrute arp seq , which is really neat.... but needs the matrix, or something like novation Sl Mk3 where you can remove some steps of the arp... or elektron where you can add some rests but also some transpose
I don't really have the answer and I'm sure you have even better solutions, but improved arps would be so great, especially with 3 arps
