Description

zb.noteTriangle implements triangle mapping to alter the pitch of the incoming notes. It is a combination of two linear mappings.

The range from zero to inCentre is linearly mapped and truncated to the range of zero to outCentre. Similarly the range from inCentre to 127 becomes the range from outCentre to 127.

Additional multiplier can be used to further compress or expand the range.

Input and output boxes serve display purposes.
