For the Piano sounds, each key was sampled/recorded 5 times (at 5 different velocities) and a cross average of about 18 mics at different positions to the "XXX" piano was used. (Can't say what piano was used).
The Hammond B3 was captured in a similar fasion, however I had to use some software for the true 'tube/pipe' feel and lesslie! Also I had over 3 great players play this beast during recording!! The idea was not to work with pre-recorded samples (the market is flooded with those), but to create mine from scratch with true 'live' feeling and not CD perfection!!
As for the Guitars, ofcourse I had to add some 'noise' to attack and sustain... now you've got that true 'strum' which has also been incoorporated into some of the styles.
When you start using the LOOPS, then you'll discover what you really have at your fingertips with the SD1Plus-EXP - esp. those incorporateed with wave sync to midifiles (hope you've had a chance to try the example I gave you)!!
Thanks,
