I am sending several messages from Processing to Max within poly~ using a target message (e.g target $1, $2 $3 $4 $5 $6 ). And I need to scale almost all of the data before sending them inside. Should I scale before the data goes inside the poly~? Does it really matter?

if you only need it once (i.e. not the same scaling for more than one voice at a time) it does not matter.

I constantly need to scale the flow of data that goes to different voices. For example, frequencies of sine waves are changing according to the size of 5 different something. And the size of 5 different things changes all the time.

"to different voices" - at the same time? i.e. the 

then avoid doing the same thing multiple times. 

otherwise it could be cool to have it inside.

especially with things like frequency or power you might later feel the need to reorganize (or switch to signal before you convert and scale). 

also IMHO "mtof" & co locally belong to the audio generator - just as in a MIDI controlled hardware.

I think your question is a bit confusing and cannot clearly answered without a proper example or patch.

You asked about scaling BEFORE or AFTER a poly~. Then I would assume you put non-audio data into a poly~ and get non-audio data out of the poly~. This is possible but is this really what you want? Or is it more like Roman pointed out, you like to generate audio inside a poly~?

In general, when receiving data from another software, the first thing I do is to scale the values into a nice range, right after the (osc/midi-)input. Ranges between -1 and 1 or 0 and 1. This gives me the option to easily shape the values.

And then, because I usually produce audio inside a poly~, I scale again for a certain task BEFORE the poly~ if all the voices should be affected or INSIDE the poly if they should be treated independently (costs more cpu).

BTW, I usually don't use target message, because in most cases I don’t care which voice is doing something.

I put non-audio data into a poly~ and get audio out of the poly~. I need to use target because in my case it is very important to deal with individual voices.

I like the idea of scaling values between -1 and 1 right after the osc input. Thanks, I'll try it.

I was just wondering how should I do it properly. Because it is a heavy patch right now, and I don't want to overload the CPU by doing it wrong.

The best was to check your cpu load on mac is to open activity monitor (applications>utilities). It shows the overall cpu load, including non-audio thread (GUI and event-based math). Certainly, there is something similar on windows, too.
