Music Composers Unite!
If I understand you, you've got a sound/patch on a keyboard workstation that you want to use within your DAW.
1. use the keyboard as an external midi instrument.
2. sample each note as audio. This can take a very long time if done properly and isn't really going to be worth the bother.
Unless you meant something else.
Thanks for all the help, but a producer friend of mine cleared things up for me.
