if you got the dough and space go get a (used md non uw if you wanna keep GAS low) …
if I am on the OT and create some drum loops, I pretty much after 14 min run into, boy am I happy to have a MD here! …
just think of tweaking that highhead, ups hihat, there just a little bit, or a retrigger of the snare (not to mention CTL machine ) , doing that on a OT is “impossible” because you only have 8 tracks ( make that 4 tracks for dums and sound locks within those, and you get a 6 maybe 8 poliphony) but hardly the fuckery options from the md ( and this is where she shines ( next to room shaking low end with the proper EQ in place ))
tl dr
yes you do need a MD (go second hand until you made up your mind)
