Welte-Mignon T-100 "Red" Test Roll
By Dave Krall
I recently acquired a batch of Welte Philharmonic pipe organ rolls.
As I was going through them to see what I had acquired, in one of the
metal canisters the Welte organ rolls came in I discovered a T-100
"Red" Welte piano test roll.
In the MMD Archives there are two posts, one from Robbie Rhodes in
1995 and another from Wayne Stahnke in 1996, where they talk about the
three known types of Red Welte test rolls:
The roll I have is on the white lined paper. It has all large holes
(no secondary smaller holes) with a fairly coarse punch advance. The
first test is a note test, followed by some sort of chord test. At
the end is a repetition test. In between are tests for the various
functions of the expression action and pedals as far as I can tell.
I assume the test roll I have is the "Monteur Skala" roll.
In pencil at the beginning of the roll is hand written "Test Roll"
along with something else that is illegible. "Test Roll" is written
at the very end where it attaches to the core. There are no notations
written anywhere on the roll as to what the individual tests are.
Can someone provide me with the notations describing each individual
