I'm using a solo Oboe instrument in Logic to get a mournful kind of sound I feel that is suitable for the start of the song I'm working on the OCRemix compo. Unfortunately, the solo oboe found within the EXS24 is only has two layers (not even velocity layers!), one of which is vibrato and the other non-vibrato.
After fussing around with the sampler - it is actually quite straightforward for the basic needs I require - but I really would not have understood how it work without youtube. Tutorials rock!
In any case, I decided to drop the vibrato layer, and just use one layer, and utilize the pitch shifter mapped to the mod wheel to create a pseudo vibrato. In addition, the default setup only utilizes the velocity of the keypress for the volume over the length of the note; this is not as flexible as I want as I would like to control how the note dies off over time, and not just end abruptly. To combat this issue, I simply remapped the channel pressure to velocity (manually drawn), so I can get a note that I can control vibrato and volume independently. And now I have to go through my other instruments to get custom variants made. GAH!
