hurm. seems like it would? it's just taking midi from it's internal keyboard and processing that with it's synth engine no? so if you send from a pattern on the Electrubsies it should interact the same way with it? you'd just be using the Electo as an external sequencer?
it's frustrating trying to have the ES2 show up as a drum machine in a DAW, but for hardware sequencing it seems like it would be pretty versatile the way each pad is a different midi channel.
