scale vs zmap (the history?)

Hello All,

So as I'm spending some time learning MaxMSP I came across something that I thought would be interesting to know the history of...scale vs zmap...

Scale includes the ability to reverse and/or make the mapping exponential over zmap. My question is - which came first - zmap or scale - and why wasn't one just retrofitted to support the other, etc. Seems these two could be the same object with default values for the extra functions in scale.

So - can anyone shed some light on the history of these objects and why they are like they are? Thanks! :-)

scale came first, but it was a third-party object. You missed another difference, though - and a fairly crucial one: zmap clips the output range, where scale does not.

And if I remember correctly, the advent of zmap coincided with jitter. In the jitter examples zmap occurs quite often. Was it that the during the development of jitter the need for a straightforward, float only, mapping device came up...
