On the Yamaha Tyros & PSR2000/2100, aren't the 'preset styles' linked to specific 'multipads' so that when you load a style, a factory pre-selected and appropriately fitting 'multipad' is automatically loaded as well?

I thought I remembered it working this way on my keyboard until today.

When I initially boot up my Tyros keyboard, the default style loaded is 'Live8Beat' and the default multipad file loaded is 'HipHop1'. Is this normal? I don't remember because I always load a custom default 'Registration Bank File' immediately after booting up the keyboard.

Ok, without loading a 'Registration Bank File' this time, I select 'ANY' preset style (like 'OrchBigBand1'). The new style loads, but for some weird reason, the 'HipHop1' multipad still remains loaded. This is weird because the 'HipHop1' multipad is obviously incompatible with 'OrchBig Band1'. When I subsequently load 'any other' style(s), the 'HipHop1' multipad still remains loaded.

I performed a Function>Utility> "System Reset" , but the above problem still continues. I also checked to confirm that my keyboard's FREEZE group setting has the 'Multipad' checkbox UNCHECKED, as well as making sure the FREEZE button is turned OFF.

Is there a specific setting on the Tyros which enables/disables the ability for specific 'multipad files' to get automatically load when preset factory styles are selected?

Thanks in advance for all feedback & help from both Tyros & PSR2000/2100 owners in helping me solve this frustrating situation. How does this work on your keyboards?
