Beaky.... 2 kits out of an entire TOTL arranger? That's your justification?
The washed out drums have been the #1 complaint about the Yamaha 'sound' for years. Probably the main reason I won't go near them... But Yamaha, instead of 'trickling' these newer MIDI kits down to the PSR (like so many other Tyros features that appear after a year or so in the PSR series) and starting to address the issue, decide to go with a proprietary, closed to user content audio system that has only 5% of the styles even used. Not to mention that any new audio styles you purchase from Yamaha won't load up without a re-boot, rendering them utterly impractical.
And, let's face it. Even for the TOTL arranger, only 2 kits out of how many? 44 drum kits..? That's barely scratching the surface of the issue.
And I'm sorry, but Tony... if you think this is Yamaha 'getting it right', you have explained a lot about your priorities. This is Yamaha completely dodging the issue, and using an utterly impractical, half-baked idea to cover a glaring need, when an existing T4 solution already exists (albeit it in its infancy). Yikes! You actually HAD an Audya, didn't you! Same technology, basically, but nearly ALL the styles had audio drums, and this pathetic excuse for a feature is floating your boat on a Yamaha while you continue to rag on the Audya..? You haven't made the connection?
Step back a bit from your current choice of arranger, and try to be a bit objective! If the Tyros had gone this route, left you with gutless drums and then only 25 styles with a good tight punchy sound and no practical way to add to them, you would be up in arms about it!
This is Yamaha wasting their AND your money... I am honestly hard pressed to think of anything other than the MS that promised so much and delivered so little.
