Just found on Sonicstate Twitter page that there are rumours that KORG will introduce on 1 November new Volcas: a Volca Wave (wavetable) and a Volca VC-1 (Vocal processing Synthesizer). It would be a Volca year because they introduce already the Volca FM and Kick this year. I hope more that a new affordable polyphonic Synthesizer will coming with more features and voices than the Minilogue. All this informations are only rumours and not confirmed.
I wonder if at all real, the volca wave will need an app to implement sounds like the volca sample unit does
