On the Tyros within a Voice Bank e.g. "Piano" from the Main Menu and then going from Voice to Voice e.g. Live! Grand to Ballad Stack, etc. using the buttons there is no delay. When you go from different Voice Banks using the Panel buttons there is a very 'slight' delay but nothing in my opinion to really hinder a person's performance. When you are in a Voice Bank and use the Back/Next buttons to go to the User/Floppy or Hard Drive there is a also a very slight delay but it is minimal at best. In the Mixing Console when using the Mixing Console Panel button it is basically instantaneous as is going from Page to Page e.g. VOL/VOICE to FILTER to TUNE to EFFECTS etc. using the Back/Next buttons on the Panel.
I hope it doesn't end up to where the Tyros2 because of its expansive feature set is similar to what happened with the PSR 9000PRO in that there were so many features on the PRO that the CPU couldn't handle all the instructions in certain situations. And this was a documented fact with the 9000PRO confirmed by the Professionals [experts] under testing and by Users.
But chips keep getting faster and faster as time goes by so I see no reason why Yamaha couldn't or (didn't??) use a Chip {CPU} on the Tyros2 that could handle everything sent to it with ease seeing how CPU speeds basically double every 18 months {Moores Law}. So from 1999 when the PRO was released to basically 2006 when the Tyros2 is hitting the streets CPU speeds have dramatically increased. I do hope this is an anamoly with the Tyros2 that can be rectified with an OS update or perhaps within the settings of the current OS.
Here we go again...
