greetings!
i'm sure this is a simple problem, but i can't seem to come up with the solution...
i'm trying to control one numerical value in a few ways:
- have a bang to set an initial value
- have a slider for mouse control
- use keyboard keys to increment and decrement
the attached patch all works, except i ALSO want the slider position to pick up the current value, as changed by any of the other methods.
the problem is, of course, that if i connect the expr result back up to the slider input, i get a loop with "stack overflow" errors.
i'd be most grateful for any pointers you can offer... thanks much!
cheers! .pltk.
I took a stab at it.
The main item here is the [set $1( message. That allows you to update the display/state of the slider without outputting a value.
The [trigger a a] isn't needed for the patch to run correctly, but it makes it easier to see the connection that feeds back up the chain.

Hi,
you could use a "set $1"-message to only set the slider's display value without letting it propagate the new value to its outlet.
Ciao

Does the send / receive "trick" to sync e.g. a numberbox and a slider still work? It seems to crash Pd on windows.

you can also use [change] in the chain to make sure messages are not resent when they are the same

See attached.
This indeed uses the IEM gui'trick' where if you set all sends and receive to the same name in the properties they will be in sync.
Please disregard my previous message about crashing.. (I was erroneously using a vanilla numberbox instead of the Number2 (IEM gui) one).
Lorenzo.
thanks to all for your responses... very helpful!
i've implemented a solution based on lorenzo's suggestion, and it works just fine! one further question:
since my slider is in a gui panel for the patch, with all the other code buried in subpatches, is there a way to get the slider's "send to float" out of view (other than just sticking it under the slider!)?
thanks again... cheers! .pltk.

by turning it into an abstraction using Graph on parent (GOP)
thanks, max!
right, so it looks like this needs to be the summer of pd tutorials!
:)

...which makes me wonder: besides all the various tutorials, is there a comprehensive online course about pd that one can work through?
cheers! .pltk.
