Just picked up my second VC340. I sold my first, despite really liking it, because of the icky B vibe. Buying a second one second hand at least means no further money goes where it oughtn't.
With my first VC340, the vocoder got lots of use as a standard "classic" vocal tool. This time around, I'm digging into the world of vocoded drum machine tracks, something that never occurred to me previously. I've got a few old drum machines that, while sounding great, have started to feel a bit tired in my hands... I've got a new enthusiasm now for mixing matching my machines.
The strings are great on the 340, though I've not yet mastered the odd triggering. I have a Korg Prologue, which can do wonderful strings, especially when run through a user-created BBD effect, but the plain-old, dumb/raw string sound from the 340 is simply groovy.
