Hi all,

I am new to pure data and would like to have a simple functionality where I store a value between 0 and 1. When I press a button, I would like to set the value to 0 (with a message bang) and then have the value interpolate back to the last stored value (with a line function)/

So, for example, if a slider is at 0.7 I would like a button which sets this to 0 and then rises up to 0.7 again.

Any help appreciated, sorry for the noob question

@dmanz I hope that it is self-explanatory....
[f] is your friend...!

$1 in a message takes the first value of a list that it receives.
A single float is always treated as a list.

Here.. more information than is necessary..... $2 takes the second value in a list... etc. etc.
You can reverse a list with 2 values by sending it into a message [$2 $1(

Hey David,

This is really helpful

The thing which is tricky for me is how to then send this value (interpolating back to the original value) back to the slider, without messing up the patch. Any advice on this aspect?

@dmanz A message [set value( will set a value in a GUI without the GUI sending the value onward.
Although in this case, because the value is only stored in [f] for later use a direct link back to the fader would work (no stack overflow).
