Sorry that should have been UD was talking ABOUT the harmoniser not used.

Of course not knowing the guy, he may very well have been talking about a vocoder, but then I think he perhaps would have named the topic Harmonisers and Vocoders

As you would know, all the vocoder does is simply play the exact notes you play, where you play them. With the disadvantage (or advantage for some??) that it also plays the notes via the sound engine too, unless turned off or down. Not to mention any slight glitch notes, they get added in too.

With some of the newer harmonisers they do not add these notes as they are not recognised as part of of the correct scale for the key. But a vocoder plays EVERYTHING, bum notes and all!! Unless in mono mode, which sorta defeats the idea really!!

They have been around for years. A lot longer than harmony units.
