Hi all, 
One module that I find very tempting and that is always threatening to pull me down the rabbit hole of eurorack madness is Mutable Instruments' Grids: http://mutable-instruments.net/modules/grids

A few years ago Henri David made a Max external version of Grids (https://github.com/hdavid/Grids) and I recently built upon his work to port that external to Pure Data: https://github.com/spoitras/Pd-Grids

I also made a patch for my Critter & Guitari Organelle that puts my new external to work: http://patchstorage.com/pd-grids/

Note: Ultimately, I intend to use this sequencer with some drum samples, but I didn't have any samples lying around that can be shared freely, so I used three drum voices created by Andy Farnell in this Organelle patch.
