Melodicer vs. Black Sequencer - one or both?

I haven't spent much time with the Erica Synths Black Sequencer, and I noticed in a thread the other day somebody mentioning it serving as a substitute for the Vermona Melodicer. Say what? I have a Melodicer, and it's the cat's meow. Can it really be supplanted by the Erica Synths offering? They're big modules, so it's worth asking the question. Which is what you have here...me asking the question of whether I keep both or just one. Source VCO is an Acid Rain Chainsaw. No envelope, just the output gates from the sequencer’s going to a Bard tube LPG. 00:00 Intro 00:20 Vermona 02:21 Black Sequencer 10:29 Tiebreaker
