Hi Garfield,
Sorry yeah I looked at the Erica Synths Drum sequencer but for the size and price point, would go with something like 512 Vector Sequencer, Winter Eloquencer or see what the new Endorphin.es ground control is like as these provide tons of useful features to chain songs and presets and more. I may just get a simple trigger sequencer for drums/bass like VPME Euclidian Rhythms and clock it with Pamela for the short run until I get a much larger 3rd case next year.
