Jay Caughron asked about punched music for the Johan de Vries
organ.  I built the organ a couple of years ago, using his original
"Kistdraaiorgel" book in Dutch, and I purchased some music from
Johnny Verbeeck in Belgium.  He is familiar with the de Vries 36-note
scale.  His e-mail address is <johnny.verbeeck@pandora.be>
