Don't remorse There's a special version of the library for folks just like you!
Pianos can be played pianistically as can other percussive instruments. But pianos are not sustaining instruments, they are percussive instruments and their sound decays once the note is played. A violin or wind instrument on the other hand can crescendo after the note is played. It can swell, vibrate, trill and do all sorts of things. Note velocity may be good for percussive instruments, but on a sustain instrument it poses a limitation. This is why we assigned dynamics to the mod wheel so you can control the dynamic flow of a note or a passage. The Mod wheel was selected because most keyboards have a mod wheel (few have an expression pedal).
But if you are not comfortable with that arrangement there are other options. There is a special version that allows users to re-assign dynamic and other controls through the assignable slider in the Player.
If you go to our download page you will see the "X-Custom Optional Folders". http://garritan.com/downloads.html
"This new addition to the library is for people who want to customize their controllers. It allows users to have custom control over volume/timbre MIDI assignments and dynamic range through the assignable slider in the Player. This feature is especially useful for users with Wind Controllers. Also, this is particularly helpful for people with certain sequencers. For instance, Logic 6 (and earlier) and GarageBand users have the reset to "0" bug which this addition will allow you to reset the controller and avoid. With the X-Custom Folders, please note that all instruments load at full volume rather than the minimum volume standard used in the Dry and Wet Audition folders. This is useful for people with Standard MIDI files they want to play or with particular sequencers as well."In addition you can acheive the same result through many sequencers. On our downloads page are MFX plugins (created by Markleford) and Sonar programming that lets you reassign the controllers. Hope this helps.
