Hello Friends
I am Manuel Dorantes and I am part of the team that develop the "Mexican-Latino-American" Expansion packs at Yamaha Corporation of America as an external consultant, I have been part of these team for almost 8-9 years now. So you have an idea, it takes us about 6 to 8 months to make an expansion pack, planing it, research, gathering song references, sort data, check if we need sampling or programing sounds, make styles, make Multipads, Make Registrations, Make OTS, etc....lots of details.
I was also doing Demos and Clinics with the expansion packs such as: Banda Mexicana, Mariachi-Norteño, Cumbia Latina y mas, Salsa, Fiesta Caliente and soon the Fiesta Caliente 2, for the PSR S, and now PSR SX and Genos...
I began to receive user questions like(since the early days of the PSR S970,etc), they told me, my keyboard froze or an unexpected window pop out and froze....and after I ask few questions, I found out that this users purchased and installed "expansion packs" made by people that has NO IDEA of the protocols, details, etc.
MANY times this "experts" Use OUR packs and literally butcher them so they "claim" to "improve" them deleting important data and adding only God knows....and the result is.....Freeze.....
Let me put it this way, if you go and buy a brand new Computer and then someone sells you none official "Software" a.k.a Virus, and you install it, what do you thing is going to happen??
I was instructed not to spend a fraction of a second of my time to try to resolve problems that someone else made that is NOT from an official source. I get correspondence from PSR S/PSRSX/Genos users from Puerto Rico, Costa Rica, Ecuador, USA, Mexico, etc....there are many "Pirates" out there. By the way, this also applies to the other brands, because this people are really prolific. You are not just risking your instrument malfunction, but the waste of money and have to live a BAD experience.
The claim that they say that they can "Add" Revo Drums to a PSR SX or other....is not possible, since is a technology that consist on layering Multi-samples for EACH drum of a Drum set (up to 27 different snares alone in ONE single drum set, besides the other toms, cymbals,etc.) and that would take an incredible amount of data.
So, Please, be careful what you buy and from who you get it from.....whatsoever, there are good reputable third parties that do sell Excellent sounds and Styles....some are so good that you find a few are in sale at the Yamahamusicsoft.com
Regards...
Manuel
