Yea big thumbs for using the drum sequencer for other things apart from drums!
If you have a euro-rack modular you can use it to trigger sequencer steps, fire off events, synchronise LFO's and of course trigger envelopes, plus whatever other crazy ideas you have in your head
I
do have a Vermona with triggers, but that is only one simple use for the BSP trigger outs. (as well as many other drum machines).
It's worth mentioning that all 3 sequencers can step outside of their original design functionality to do lots of other stuff with a modular system, depending on the modules you have.
