I'm very new (second day demoing Max), apologies if this is simple stuff but I have searched and not found an answer:

I'm trying to assemble an audio effect processor in Max. I've got a simple subpatch which is basically a bypass toggle switch using a gate and selector, with a bpatcher inside it which loads the actual effect processor to be bypassed.

It occurred to me that rather than reproduce this patch with different bpatcher objects inside, I could probably have several instances of this subpatch and simply pass in a message via an extra inlet to tell it what patch to load into its bpatcher, but I can't figure out how to do that. If I don't specify an initial object name for a bpatcher I get a box with no inputs, so I can't pass it a message to instantiate an object.

I've seen mention in the documentation of naming the bpatcher using the inspector and then firing messages at it using a js object, but I thought I'd ask in here if I'm barking up the wrong tree before I go too far down that route, given that I have limited time with the demo, and it's now bed time...

As it happens I am a Javascript developer so if that's where this is going that's fine by me.

hi kevnull - did you consider making a dummy object that has the input to be instantiated through?

Hi, thanks for your reply. I'm sorry but I don't understand - do you mean initializing it with an object that has an input purely to provide a way in? How would I then use that input to load a different patch?

with the "replace" message - check the reference for bpatcher on that. If you provide it a scripting name you can use [thispatcher] to access it, too, iirc, so it can just be a fully empty bpatcher.

wouldn't you know, mark just posted an example over here:

Excellent, thanks! I'll give it a try tomorrow evening, tonight got eaten by a rehearsal.

That's brilliant, exactly what I was after. Thank you. :)
