The min and max numbers shown by BC Manager (Value 1 and 2 nowadays,
actually) are exactly the same as the ones Royce instructed you to
use: $3FFF is simply 16383 in hexadecimal notation, and $3FFC is 16380.

In your previous mail you suggested that BC Manager "converts" the
negative values, but I'm kind of relieved that this turns out to be
not the case: Royce's default and minmax statements don't use negative
numbers either - it's simply a restriction of the BCR (and indeed
MIDI) that you can't use negative numbers as such.

It's just a matter of how your VFX works, in the sense that it
interprets $3FFF=16383 as a negative number.

Yes, BCL (the B-Control Language) allows both decimal and hexadecimal
notation after ".default" and ".minmax" (and in many other places).

I've racked my brains over this problem, but I can't see a way to do
this. The problem is simply that the BCR doesn't allow a "wrapped"
range from e.g. 16380 to 4 (meaning -4 to +4 on the VFX). Maybe the
best you can do is to use a pair of encoders, similar to the way Royce
helped you with for buttons, but I totally admit that it's silly that
it probably can't be done via a single encoder.

Mark.
