Elevation - Op.29 No.3

An easy piece for a rank beginner like me :-)
The Pipeloops set doesn't have an expression pedal and although I've tried going from Fonds 8' to Fonds 16/8/4 in part of it, it was too abrupt a change and sounded unconvincing so I've left it as Fonds 8 throughout.
I haven't got a pedalboard so I play the pedal part using two foot switches and a program I wrote which translates those into the required sequence of notes.
