X
Version: 2.0 (22 September 1997)
X
Author: Richard Hagen
X R.H...@mailbox.uq.edu.au
X
Distribution: Freeware. See the copyright notice in scaler.c.
X
Requirements for running:
X Bars and Pipes professional.
X
Requirements for recompiling:
X DICE (or some other C compiler)
X bars.h and toolstart.c from the Rules for Tools package.
X
Usage:
X This is a normal tool, which can be used anywhere in Bars and Pipes.
X Scaler takes control change messages and scales them into some
X specified range.
X
X It is controlled by five gadgets:
X
X CC# (proportional gadget, range [0 .. 127])
X Selects the control change number that is to be scaled.
X
X Input min (proportional gadget, range [0 .. 127])
X The minimum end of the range of the input CC values.
X
X Input max (proportional gadget, range [0 .. 127])
X The maximum end of the range of the input CC values.
X
X Output min (proportional gadget, range [0 .. 127])
X The minimum end of the range of the output CC values.
X
X Output max (proportional gadget, range [0 .. 127])
X The maximum end of the range of the output CC values.
X
Useful for:
X Combining with my CCCC tool.
X
History:
X 2.0 (22 September 1997)
X Added input range.
X
X 1.2 (22 September 1997)
X Code improvement.
X
X 1.1 (13 September 1997)
X Redrew icon. Ensured that tool was properly initialised.
