I'm adding a lower octave of pipes to my home-made MIDI band organ.
Since I gave little thought to what I've built and some of the pipes
seem crowded, it's a good time to start over and build new boxes.

Are there guidelines on how to lay out the pipes?  How close to each
other can the ranks be?  Should the ranks be chromatic or is another
arrangement better?  Should the bass pipes be in front or in back or
could they be in the back and play toward the back?  Where should the
dog whistle flutes go?

Before I start this redo I'm looking for advice.

Thanks,
Bill Clark
