Yamaha wasn’t presenting any synth at NAMM but they put up a nice history page –
but there’s a little 8 voice synth in it near the AN1x Digital Synthesizer but not exactly IT plus drums – called SynthBook and within the iOS App it’s called AN2015 running on iPhones..
here’s what you can do – see the tabs? it’s quite capable of a lot of synthesis.
and there is plenty of cool things up on their site on history..

A users render about Yamahas future – do you think they do this kind of effort without bringing new synths somewhere sooner/later?
