Hi Hein,

as Andy wrote, you can do Easy Record and then Multi Track Recording without having to save the sequence after Easy Record.
I also own a Technics keyboard and the difference between the PSR 9000 and the Technics is, that you can make only one sequence at time (on my Technics I can record or load into sequencer up to 10 songs) and you cannot do anything else between recording: if you push the Exit button from the Sequencing Mode, you will be asked for a confirmatin of the action, as all sequenced data would be erased.
I found the Easy Record very convenient and also the Multitrack Record works very similar as by Technics keyboards.

Regards

Marek
