[LAD] Open Keyboard: Request for velocity curve information

Hi, Many thanks for all feedback on my original posting about what features you would like to see in an open midi controller... Based on your "requests" I've started experimenting a bit with adding rotary encoders and a 20x4 lcd display. I've changed to a more powerful (but still cheap and easy to work with) microcontroller atmega128 (from atmega16). If you're not familiar with microcontrollers you might be familiar with the arduino platform which also uses an atmega (but the lesses atmega168). Now to my question: Does anyone have some sample velocity curves, like a mapping from key velocity to midi velocity for different instruments (grand piano etc)? There doesn't seem to be any convention on how to handle velocity data?? Does some synths expect linear mapping and does the "mapping" in software?? --Albin
