A counter driven by a metro with a period N ms has its increment value set to -1, 0 or 1 by messages. Don't forget you need the 0 to halt it. Limits are set by min and max.
This implementatiion has a small bug. When you change direction the last value stored in the float is flushed through so it overshoots by 1 in either direction. But it's simple to understand.

Using a joystick pad to send a +1 or -1; when the value changes to +1, I want to increment a value every N ms, and when it is -1, I want it to subtract from the value every N ms.
This will, in effect, cause the value to slide, at speed of N, between 0 and 127. I would also need to have these values limited so they do not slide lower than zero or above 127.
any hints on how to implement this?
thanks!! jjh
