sorry but i think novation are rather misleading about this.
check out the manual they dont realy say word by word its pure analog.
vcf can easly be analog emulated filter.
anyhow i could be wrong on this one.
it would be nice to see a new version of the bass station with builtin 303 style step sequencer with an affordable price,299 maybe
if they like they could include a drum station engine aswell into it for a total tb-tr machine.
