[PD] newbie ? - quantize controller data

[Mark Casey]

Hello,

I'm new to Pd. I play MIDI wind controller and Pd looks like just the ticket
to realize my long standing performance goal. That is to take the single
note data stream and seamlessly switch between lead and rhythm parts. The
rhythm parts would be chords but not locked into parallel voicings. The
processed MIDI data will trigger hardware synths.

I'm on OS X 10.2.8, dual 450, midiman 2x2 interface, Pd version 0.37.0

Outputting chords based on MIDI note number is pretty straight forward
thanks to Jim Aikin's transposer patch. Now I want to change voicings via
continuous controller rather than the radio buttons currently used.

The first attempt used moses to split the range into 4 zones but this bangs
the transposer every time the controller changes. What I need is a single
bang for the entire time the controller stays in a range - only sending a
new bang when the controller passes a upper or lower threshold.

Would you point me to a resource or perhaps offer suggestions for achieving
this?

Thanks for your help.
