Hi List,

I've a simple abstraction that instantiate a single output channel plus a VU meter and a mute switch. In this abstraction I create a dac~ object. I would like to make this channel selectable by a creation argument. This is simple to obtain by using the object [dac~ $1] but this make mandatory for the user so give the channel number as a creation argument. If I instantiate the abstraction without a creation argument, $1 will be 0, and thus, I've no output to the dac.

What I want is:

• when the patch is instantiated as [patch_name channel_num], the dac~

object in that patch should be [dac~ channel_num]

• when the patch is instantiated as [patch_name], the dac~ object in

that patch should be [dac~ 1] (or other default channel)

I've temporarily resolved this using throw~, since the throw object accept the message [set bus_name(, but in this way, I'm forced to create the correspondant [catch~ bus_name] and link them to a given [dac~ channel_num]. And I don't want this! :)

why don't you want this?

Basically, I need a procedure to set the dac~ channel during the init of an abstraction to $1 if passed or to default_channe il $1 is not passed.

there is a way with dynamic patching, dac~ could be created at abstraction init with default arg, if you don't know how to do this I've attached an example

Thank you very much!
