After posting my worries about the Motif ES, I ran across this message from Yamaha marketing at http://www.sninety.com/forums/showflat.php?Cat=1,3&Board=Plugboard&Number=27449& page=0&view=collapsed&sb=5&o=&fpart=28:
\"One of the less obvious features of the ES is that the new chip will load LPC compressed waves. Almost all of the waves inside the Motif and other Yamaha products are compressed by LPC coding which means that you get twice as long a sample in typically half the size.
What does this mean ? If you had 512 MB of sample RAM in ES and we created a 1 GIG piano and compressed it with LPC it would load into the ES. FYI, you can not edit LPC compressed files, they can just be played back.
The biggest real world advantage is loading time in that a file that is 64 MB in length and is then compressed to 32 MB loads as a 32 MB file , that is in half the time of the original uncompressed file.
The final advantage is that since it is compressed in a proprietary format it can only be read by the Motif ES and it can not be exported as .wav or AIFF . We believe third party companies will see this as a defacto copy protection mechanism ( it only plays back on Motif ES) and therefore make lots of libraries.
They can take an exisitng CDROM and easily modify so that it loads in half the time. We wil be working with a number of them to either provide them with the compression tool or havea team of people here to do the compression for them.\"
Sounds better and better. Has anyone been contacted by Yamaha about building these piano libraries?
