I'm trying to make a patch can slide from values between 2 dials which control volume. It does this by the values of the 2nd dial from the value of the first then dividing it by the metronome speed. This value should then be added to the current volume value 1 millisecond at a time until it reaches the value of dial 2. (really hard to explain)

my question: How can I add 1 number to another until it reaches the correct value? all the ways I tried ended up with a stack error.

not sure what you mean ? but i think [bline] might hold the answer ?

To avoid stack overflow in general, read up on the 'set' message that 

is available for practically every object you're using.

To your problem. Your description is vague-ish.(*) I think you want 

metro -> gate -> int -> + (or accum) -> dial

The gate's left inlet will be controlled by a test for whether the 

dial has reached the desired value. Something like a < object with 

the current value in the left inlet and the desired value in the 

right inlet. (Alternately, you could skip the gate and just have the 

test turn the metro on and off as needed.)

This is covered in the Max Tutorials 15 & 17. Have you understood 

(*) In general, if you can describe a problem precisely enough so 

that other people can understand it, you're half way there to solving

This sounds like you didn't think about the time. If you tell the 

computer to increase within a loop, it would try to do so within no 

time. The time is the key. I guess you didn't tell how slow you want 

look into the following objects: line, delay, pipe...

For your specific question, I made an abHaxion resembling the Pd object 

called "until". You can find it at the share pages of c74. Look into it

And of course all those tutorials.

called "until". You can find it at the share pages of c74. Look into it 
to find out how to stop a loop...

if the [!+ ] object does not help you here, maybe

[110.ATC] does after you changed a few things inside

Increase values? - noob question!
