hey all.  just installed the vintage collection ROM in my px-7 and 
it's appearing like the sounds from the vintage ROM are not 
responding to either LFO rate or LFO amount.  turning the knobs 
doesn't do anything.  Neither does changing them from the preset 
menu.

Everything else seems to be working fine.

the sounds from the ROM that came included with the PX-7 is behaving 
like it should. 

any ideas?
