There is very serious ommision on both the SD3 module & the SD5 keyboard - no USB to Device port, for a flash drive or external Hard Drive - not even an SD Card slot which almost every cheap camera has nowadays.
A floppy disk is steam age technology nowadays and a cost of £250 (UK) for a small internal Hard drive is far too much for far too little, when I have bought a 500 Gb external Hard Drive for my computer for £85.

After reading a brilliant review of the SD5 (on Jazzhooves), I had intended to buy an SD3 as soon as they hit the market - I consider the £1300 asking price (BCK) to be a fair price for this module, (which is a complete SD5 keyboard without the keys & speakers) but I don't want to go back to using slow & outdated floppy disks after using an SD card on my Technics KN7000 (as good as any hard drive I.M.H.O.)

Ketron make quality products with good sounds and features and they have been one of the few manufacturers to keep producing Module versions of their keyboards. I have praised them constantly for this and wish to continue my support for them - but the lack of cheap and convenient storage is a big turn-off in my opinion and I'm now reluctant to make the purchase.

I have invited AJ or, better still, someone from Ketron themselves, to comment on this but the silence is deafening.
