Python - add channels to a Constant CHOP?

General TouchDesigner Discussion
1

The Constant CHOP acts like a list of channels, but this appears to a be a read-only list. Is that correct? Looking for a programmatic way to add and remove channels.

I can do this:

[code]oldvalue = op(‘constant’)[‘ExistingChan’].eval()
print(oldvalue)

.25[/code]

I want to do something like:

op('constant')['NewChan'] = 0.5

You need to alter the “parameter” attached to that number. The channels created are ready only, but the constant CHOP creates channels via its value parameters.

So you would do this:

op('constant').par.value0.val = 0.5

So there isn’t a real direct way to adjust it by name. You’d probably need to set up a script CHOP to do that.

You could use a Script CHOP.
That allows you to add and remove and manipulate channels.
