Does anyone know how to build this? I'm working on one right now. The A/D part works wonderfully but when I try to toggle the cycle and bang it, the bang seems to cause the overflow. I tried adding a delay to it, but it freezes without the "overflow" printed until I toggle the cycle off.

This is similar a module I have for my synth. I wanted to emulate it for MIDI instead.

Thanks in advance!

could you post your patch please?

Yes...here it is.

I should note that it runs NOT like the module I posted. It's sort of like Roland's system of using T1-T4 for time and L1-L3 to change the envelope.

first it's important to know, that an operation with control objects like [+] have a "hot" inlet (left) and a "cold" inlet (right). the operation is only triggered at the hot inlet, so if you want to trigger an operation by the cold inlet too, you have to send a bang to the hot inlet, when the value at the cold inlet changes. you can do this with the [trigger] or [t] object. have a look at the attached patch. [t b f] sends first the float value at it's inlet to it's right outlet, then a bang to it's left outlet.is there a reason why you used the [expr] objects, since you could also use the common [+] and [>=] objects?
however, have a look at the patch and check out, if suits your needs.

Hey toxonic. Thanks a lot for your help! I'm not the most programmed oriented person, so my coding is pretty bad. After going over your code, I realize I haven't been taking advantage of basic things like syntax in a message boxes!

I do have a question: is there a reason why you are using vline~ instead of line?
