I challenge everyone to show me another manufacturer besides Yamaha who is adding more value to their arranger line by adding NEW Styles, NEW Multi-Pads, NEW Registrations,and NEW VOICES?
Laugh all you want, but it is a very cozy marriage; Yamaha is making money, and their customers are reaping the rewards of having more expandability options.
Is Ketron doing this? NOPE
Is Korg doing this? NOPE
Is Roland doing this? NOPE
Is Lionstracs doing this? NOPE
Is Casio doing this? NOPE
If they were, I'd probably have one of those manufacturers products in my studio.
If you have a keyboard that can load external sounds (Akai, VSTi etc.) you have a lot more sounds available than Yamaha provide for their instruments. (Remember Akai & VSTi are used in studios and in films)
If you have a computer based keyboard, new features etc. can be constantly added without needing to buy a new keyboard to get them.
Wersi currently has 16 Sound/Style/Pre-set option packs for its OAS 7 instruments, with many more available from 3rd party suppliers. (Including Pemo)
If you have the OAA option (Standard on new instruments) you can also directly play Yamaha styles (No conversion takes place) up to Tyros 2, thus you have access to most of the available Yamaha style library as well. (Yamaha styles are not really my cup of tea though)
So there you have it, Yamaha is not the only manufacture supporting their customer with expansions. (And don’t forget that most Korg keyboards can also load Akai samples as well)
Another advantage for any keyboard that can load external sounds beyond what the manufacture supplies is that you can buy what you want, rather than having to hope the manufacture will provide them.
