Diki,
As I pointed out it might be of lesser interest to those with a Tyros,PA3X or G70 ( still interesting enough though, see below) but it sure as hell is mighty interesting for anyone with ANY other Yamaha,Korg or Roland keyboard. AS far as the forum goes here I am thinking about folks like Gary, Larry , Deane to mention but a few who will find it a treat. Sure to progam it is fantastic but even as a major volume mixer on stage it is great I think. Do not forget that I have also programmed the uppers volumes under the rotary buttons.
As to your question about resetting the registration, I will test it tonight but I am all but sure you do not have to reactivate the registration.
And as to using it with the G70, I still think it would be handier ( bigger reach of sliders, volumes uppers etc. included in the same batch). Seeing you already have got one it is sure worth trying out other stuff like programming the reverbs, or whatever. If you use the LEARN function (see your manual or download manual) you can program virtually anything there...........
regards
John
