  Subject: Chest arrangements [was Zwolle & Noordbroek]


  A couple of technical questions:

  Does the tuning effect of a particular arrangement of pipes on the 
  chest, such as M3rds, apply only to mechanical action and slider 
  chests, or does it also carry over to electro-pneumo, etc.? Or does 
  it apply to slider chests, no matter the valve action?

  On mechanical actions, do non-chromatic chests require any more 
  work/design effort with regards to roller boards and such?

  I have often wondered why M3rd chests weren't more widely used, 
  simply because of the better tuning stability.
