[ Ref. Dave Vincent in 170131 MMDigest ]

Hello MMD,  we have a multitude of Dutch subscribers on here who
will know way better then I do, but from my knowledge:

- Biphone on Melody is usually a single rank to be mixed with
Celeste/Violin.

- Biphone on Countermelody are two ranks in "Schwebung" (wobbled)
off-tuning.  [Similar to Celeste and Unda Maris voices.  -- Robbie]

As our Editor posted, these are by default played in Tremolo throughout.
