Larry:
MegaVoices are different than regular voices. They vary depending upon the velocity used and the note. This is the way that Yamaha is able to get different samples to be triggered from the same program specification.
An example:
Steel Guitar
C-B5: velocity= 1-20 is Open Soft, 21-40 is Open Medium, 41-60 is Open Hard, 61-75 is Dead, 76-90 is Mute, 91-105 is Hammer, 106-120 is Slide, 121-127 is Harmonics.
C6-B7: all velocities, strum noise C8-G8: all valocities, fret noise
That is quite a lot of guitar to be available to one midi program change specification.
Now, while a live player can control the note pitch with ease, restricting the velocity to a narrow range is almost impossible. Therefore, playing these voices(in the megavoice formmat) live is not really an option. But Yamaha makes up for it by using the same samples in the Preset voices. They are very similar overall, but do not contain the effects such as fret noise, etc.
Many users have reactions similar to yours-"why can't they be used everywhere". The answer is "They are too complex". Yamaha could have hidden them from the users and only called them for their own styles and midis, but, to their credit, they did not.
Instead, they made them fully available on the instrument for use in style generation (the PSRs have a pattern copy function that works well with them) and have recently introduced a PC program (MegaEnhancer) that will incorporate them in a midi (with some of the sound effects included).
Confusing- yes, a notable technical advance- absolutely. If they had been able to perform the MegaEnhancer function in the PSR whenever a megavoice was specified, and made the PC version available with the Tyros introduction, then this issue would never have developed. But it has come later, outside the instrument, and with little user education.
The cutting edge of technology is often not comfortable. In this case, in my opinion, the minor inconveniences caused by the megavoice implementation issues are worth it.
Regards,
Michael
