That was quite interesting ... I would have liked to know what the buttons were that he was pushing, and how much was pre-recorded ...
The pads have several modes, the main modes are...
Phrases ( allowing you to trigger midi phrases)
Samples ( allowing you to trigger samples and drum sounds)
-- all these can be looped and synced in tempo and follow chord changes
Chords ( allowing you to trigger chords and chord sequences for the auto arranger)
And then there is multi mode, thats the mode Ralph maten is using. In which you can assign any of the 3 above to a pad and some more functions like switching articulations (like the sa1 and sa2 buttons on tyros) or triggering midi messages, or switching effects on or of.. I.e most things you can think of that you would want to assign to a button..
This is the mode ralph is using with the buttons, multi mode, mostly triggering samples tough much like 16 Multipads
You can quickly switch between the modes by using the smaller buttons to the left of the pads
I have a different opinion of the looks of this keyboard. I actually quite like it. The multifunctional pass combined with the touchsreen adds a whole different level of controll over your performance. Now all you need to remember is what functions are hidden under what pads for each of your performances..
