I was going to mention what seems like a trend now to box up keyboards into something more resembling an organ , I see Ricardus noticed this same thing . A volume pedal might be a nice addition , maybe even a set of ceremonial daggers to wedge the keys down .

Ive wiled away many many happy hours woodworking ,
Varnishes and other wood finishes are gone so expensive these days I been trying the old style linseed oil based finishes on garden furniture and tools with wooden handles.
Generally I make a blend of equine grade Linseed , turpentine and tea tree oil . Its simply brushed ,ragged or rollered on , the catch is it does take time to dry and cure . For me the fact that its all natural and easily made up yourself from plant based ingredients makes good ecological sense. Applying a polish made with a blend of bees wax, linseed and turpentine every once in a while and water bounces off .
