Ketron SD90 - the truth about usability 

Thank you for your fantastic content. Cheers

Excelent video Thanks Tiho You are very professional Regards from Portugal

Thankyou! You Explain the Ketron SD 90 Very Good !

Page turning function is very powerful, just click more, Learned. Thank you!😊

Ketron pedals FS6 & FS13 are a great alternative to change parameters in a Ketron SD in a live performance(with the foot)

Also no buttons to tap on Event , to scroll & select VOICE , this feature on SD90 is not available on EVENT ! only the SCROLL WHEEL on EVENT :(

on Event , you need to scroll the wheel, to select a style, to go to next page, there are no buttons to tap, like SD90 :(

sir can I ask a question？ SD90 how to record audio into the U disk? I didn't understand it after studying for a long time, so I have to consult you. Thank you very much.
