University project – Help with maths please

Attatched is one piece of my Cellular Automata instrument

Please open the patch and have a look

I need to understand how to do everything written in blue text before I can move forward. I’m sure there isa fast and easy way to do these calculations but any help or advice on HOW would be absolutely fantastic

Thanks in advance – feel free to chop and change the patch

ah-ha! i can use that to get a mean value (basically a percentage – sort of but it will do fine) cheers

From here though how do I go about making the mathematical expressions?

Can I make a table of expressions?
A table of Values?
A general Table of data to be referenced etc etc etc
- If so how do I specify how to evaluate the list of data in the table correctly?

or is it best to create a message that will evaluate the list of numbers.

In its simplest form I would like the instrument to produce a tone (I’ll connect was phasor~ or oscbank~ objects for sound gneration) but say for >0,>10,>20,>30….>80,>90 % of ‘life’ I want the instrument to automatically select the output tone/frequency (100Hz, 200Hz . . . . . .2kHz, 3kHz.

If I can set up this instrument in a way where I can easily edit the expression I can really get stuck into making sounds with it, expolre different scales, and use this idea of the 10%,20%,30% etc in conjunction with for example LFO speed, sample playback position, delay or reverb times etc etc etc. so I have to work out how to ‘phrase’ the mathematical expression (wether or not it ends up looking up a table or is just a text comment connected to the matrix and some sort of sound module,
