My brother Anthony Caston is visiting from the UK with his wife Sheena, daughter Lucy and son Dougal. At just sixteen years old, Dougal is an accomplished jazz saxophonist who has already had the opportunity to perform and audition with several well know jazz musicians.
He hopes to attend the London Royal Academy of Music or Trinity College of Music in about eighteen months. Dougal sat in with my group Keston and Westdal at the Kitty Cat Klub in Minneapolis last Wednesday, and last Saturday we spent nearly seven hours jamming in my studio. Here’s a short phrase of his playing that I recorded with my AKG c4000b.
Shown at right is my nephew Dougal giving my nephew Tony an early saxophone lesson in my dining room in Minneapolis.

Today during my audio production class I was demonstrating to my students how time correction impacts digital audio when pitch shifting more than a few semitones. To illustrate this I pitched down a chunk of music an octave with the time correction on in Pro Tools. The degradation was clear, but it occurred to me that it would be even more obvious if I shifted it back up to the original pitch with time correction enabled again.
