I just got a nice E-Mail to check out this Vocoder. As the name says it is a Vocoder with 3 modes (big like the Uran-Vocoder of Kraftwerks talks about nuclear power plants “xx Mio tonn of Plutonium every year…” – to a higher one. It has a little latency – but the quality is really really good. much more like a high end vocoder than just a toy. it’s capable of 2 notes (tap the face) and has a 9 band EQ as well. they say it’s modeled after the EMS – seems true. Works on the iPad and iPhone. Had no problems with feedbacks.
