I attached the score below.
The editor recommend to play the piece without 16'-stops in the pedal. Only at the end of the piece I added the soft Subbass.
The first "soloist" are the tremmed 8'-stops from the RP accompained by Fl.Harm+Gedackt8 HW.
The canon I played with the SW (soft 8'-stops) and the wonderful "Vox Ludgeri", a free-reed Clarinet.
