There is a complete range of accessories for these little beauties, volume pedals, stands, cases, chargers and battery packs and software music books galore ... you can even connect to a Leslie cabinet as it has a dedicated output for one.
An extensive search on the 'intra-web' revealed no further information ... although I have managed to find a short demo song which I have put together with several more pictures in the video further down.
I am really curious to know if they have got those drawbars hooked up to the traditional Hammond sound ... certainly not apparent from the demo tune although, it does kind of imply they have as according to the specifications both keyboards have 'key-click' ... anyway, here are the specifications for both models.
Oddly enough the HEK-3 is quite a few thousand Yen less expensive than the HEK-2 despite the spec' being marginally better ... Interesting little instruments ... Tyros 5 ... watch your back
