>"The original sampling drum machine was created by Roger Nichols in 1978 for now-somewhat-forgotten 70s band Steely Dan.
Steely Dan has been a continuous staple of AOR and classic rock radio since their first album in 1972. There was even a huge resurgence of their popularity with the whole "yacht rock" movement. They even won three Grammys for 2001's "Two Against Nature" record.
>"The Steely Dan people were notoriously obsessive about drum timing, which was a bad thing to be when all you had were human drummers."
This is not correct. Steely Dan's stable of studio musicians were the best in the business. Their drummers on this album Rick Marotta, Steve Gadd, Jeff Porcaro and Bernard Purdie would all be considered perfect time keepers. The impetus for the creation of the "Wendell" was not to make up for precision in time keeping, it's primary function was as a drum sampler. This would then allow Becker and Fagen the ability to obsessively control things like inflection - a softer high hat here, a different snare accent there, after the drums were recorded. It's primary function was not a source of time keeping. For example it's actually Rick Marotta's drum playing you hear on "Hey Nineteen", just sampled via the Wendell and then compiled from many different takes.
