Pam’s Pro Workout is accurate enough to serve as both the master clock and drum sequencer, but I’m more drawn to the 6equencer. It’s immediate and avoids menu diving; it just lacks the clocking capabilities.
Pamela can sequence, but it doesn't have the hands-on control you'll want or even need in a live situation. Do you currently own this system? How do you feel about it?
The budget-friendly fix is to get a hardware sequencer, although the OXIs are very expensive. But just using that for drums seems like a waste, I would also remove Rene if you go this route.
If you just want drum sequencing without melody, check out these:
* Robaux LL8 2 or Robaux SWT16(+). These are tiny, no menus, no saving, cheap for Eurorack, very quick to use. Eight or sixteen drum channels.
* Doepfer A-157-1 (you need -1, -2 and -3 as a set). This is huge, no menus, no saving, you can see and directly edit all of the drum parts. Eight channels.
* vpme.de Euclidean Circles v2. Tiny, six channels, no saving, very quick to use, very musical because of the euclidean system. You don't have total freedom because it only has euclidian rhythms.
* Intellijel Steppy. This one is pretty popular, it's good and hast the most options. Internal memory. just four channels.
I also want to mention that the Bohm expanders need to be connected to the main module in the back, so the way you're spreading them now should not be possible.
