Scott: here I wrote to Rikki the things I use/do when I change keyboards and re-map Midi files voicing them to take advantage of the BETTER sounds on the new unit rather than the 128 GM/XG ok sounds.

"Hi Rikki:
I did owned not just 2 SD1s, also a X1 too, well, the midi file re-voiced in song setup in the SD1+ has only the instructions of those changes only for the Ketron, but the midi file remains unchanged unless you remaped the voices and controllers in the PC with any secuencer program such like Cake/Sonar, etc....I did changed in the PC (with Cake/Sonar)the few midi files I did use, I also find that I have more control even in the dynamics, fx, etc...
As an example for my own experince is:
in the Reverb (control 91) to have a decent reverb in the SD1 you must set up at least 100-127 value(from 0-127), but in the case of the Yamaha Arrangers like the PSR3000, T2, you need less, around 50-70 depending on how much FX you like, each manufacturer FX procesor has diferent sensibilities, also may I point that also the note velocity response is diferent, I have to lower it if I play a file in the Yamaha, somewhere 50-80 note velocity range is ok, more, sounds overdriving it, but velocity ranges between 100-127 are just fine for the Ketron.
Needless to say, I do recomend to make the adjusments to each midi file in each track in the PC, well, at least I do it like that, perhaps because I am very picky.

In the drum maps, I still use the PC, because sometimes you get a file that has an annoying clap that should be a snare (as an example), that, only can be remap in the PC with the Piano roller mode, is a very fast procedure, this is not posible to do in the Tyros2-SD1+ yet, only change the drum kit and volume, fx overall.

Or you get a cymbal that is a little to loud, or the hihats to low, well, I use the Cals (Bustdrum) for Cakewalk/Sonar, so, I make the note velocity adjustment and that is it."

By the way, I do like to use Cake/Sonar software because you can add the "Instrument Definitions" for your particular brand/model, and that way you can edit the patches seen the real names of the sound banks, rather than a Bank number and a patch number, is easier and faster.
Also the CALS that are like the macros (for those who use a word procesor), is a program within the Cake/Sonar, this are user writable to suit your needs....you can Humanize an over quantized track, adjust volumes in EACH percution instrument within teh Drum Kits, control dynamics (velocity (VELPCT) porcentage that allows you to let say, lower the velocities without altering the dinamics, another is to make a track less monotonous, as an example, you have a track with the bass, and all the song has 127 note velocity, so, a bass player never plays at the same volume everynote, so, I use the VARYVEL (velocity variations), in wich you choose the range, lets say from 110 to 127, and in a split second, that track will randomly will make this variations, and so on. I thing is a wonderful software, a great tool.
