Should I use poly~, polybuffer~, or just copy and paste?!

Apr 15 2012 | 1:38 pm


I’m attempting to work with sampling and sequencing but I’ve run into a bit of trouble with it. My problem is that I need several individual buffers, waveforms, and other items, each with different names (buffer~ test, buffer~ testtwo, for example). I will probably need over 100 of these to start off with.

I’m thinking of using the poly~ object but I’m not sure if it will work for me. If I create a poly~ with over 100 instances, is there an easy way to rename each individual buffer? Should I send a target message to each instance of poly with the message [name example_buffer_one] for example?

This will also be the case when coming out of the poly~. I will need to have each external (by external, I mean not inside poly) waveform~ receive the [set/name] message which corresponds with the selected buffer~ from inside poly~.

There are other problems but I’ll try to tackle this one for now!

I understand how poly~ works but I’ve never dealt with it outside the realm of polyphonic synthesis and midi.

Can someone help me please?

polybuffer~ and poly~ work great together. Just use thispatcher~, make him send its instance number, and as each of your polybuffer’s buffer have a name which is constituted with :
you just have to use a sprintf to format the name of each buffer, and the number index is the only thing that needs to be changed, adn how convenient ! that’s something you can have easily with the instance index coming from thispatcher~. it’s like they were designed to work together :)
As for your outs : do you want each instance send its signal to a particular waveform~, at the same time ? In this case, you can use send~ form inside your poly, and set message, which can be depending of the instance as explained above.
if you don’t need this, but rather one instance selected at a time, it’s not that complicated : you just need to save "set [thisinstancebuffername]" message inside the poly, and output it when it’s selected, and send it to your waveform~. Alternatively you could have a waveform inside each poly instance, maybe computer expensive.
And if the overall process is too expensive, you can mute each unused instance of poly with thispatcher~.

Great. Thanks for the tip! I’ve been working on this and I have made a lot of progress! And I shall be displaying each waveform~ separately! So that makes things easier too.

: )

I have another question though…

I am also using [sprintf], [mousestate], and [thispatcher] (plus many more objects) combined to report the position of ubuttons on my home patch. The only problem is, I need a ‘polyphonic’ way of working with this too.

For example, when I drag a specific textbutton over a specific ubutton which is in a certain place (let’s say patching rectangle 0. 585. 45. 45.) I get a bang once I release the mouse, which consequently loads a waveform, etc, etc.

How can I do this in polyphony? Because each ubutton is in a different location, is this impossible (or incredibly complicated)?

Without using 100s of [split] and/or [if] objects…

It’s driving me insane!

Thanks again!

Anyone? : /

I’m going mad!

I guess [copy and paste] it is!

i don’t really see what you want to do, but maybe using [hover] with script-named objects will help you ?

Sorry. Maybe I wasn’t clear enough.

For example, I have 100 ubuttons, each in different locations on my patch. When I scroll the mouse over each one, something happens… something unique to each ubutton. I am using mousestate, hover, etc. etc. to make something happen each time I hover over the specific ubuttons.

Here’s the problem:

Instead of saying (for example) if mouse is over ubutton 1, do this, and if mouse is over ubutton 2, do something else, etc., etc., can I use poly~ in any way to help me avoid the monotony of copy and pasting, ultimately requiring less processing power too.

Even if I do use scripting names, won’t I still have to create an independent [if] statement for each ubutton?

Maybe I’m wrong!

Thanks for listening!

bpatcher perhaps?

Thanks for your help, but I think Javascript/scripting, etc. is what I’m looking for.

It’s time to refresh my JS skills!
