I totally understand those who are fed up by my posting/asking...

I think i need help with something like linear or exponential curve...

I want to type/change a number in a frequency box, then send the number to different object boxes, then ba able to change wether each number is twice/three times or 10% the size of each other,

but the relation between them is always the same. Does this make sence?

If I understand this correct, you want to route the frequency according 

to a range. Look into split, with float arguments it will work with 

floats. You might need several split objects. Or you could also devide 

(Math is never hopeless, because its so logical... ;-)

If I understand this correct, you want to route the frequency according 
to a range. Look into split, with float arguments it will work with 
floats. You might need several split objects. Or you could also devide 
by your factor and use a route object...

Does comparisions work with floats - so i can have the frequency eqivalent to a midi note and make zones for signal processing like from c3 to f3, turn left and amplitude modulate....

i want this to work not only by changing pitch by playing different

midinotes, but foremost by changing frequency with (function) envelopes.

I forgot to post my example... In general all can work with floats. You 

have to give mostly float arguments to turn an operator into its float

Better yet... play those data points as MIDI notes.... wacky fun

thanks alot, but ehhhm what does it do? I understand its a kind of linear curve, where i plot in the Variables, but the rest is greec :)

this is also a linear curve, is it difficult (and useful) to make it into an exponential curve?

Well, the top part is for simple scaling of a main value. Good for making harmonic frequencies (integer or float) of a main frequency value. Build up your synthesizer with banks of these, store the multipliers as presets (pattrs even better). You could use a multislider for the values, and another one for the volume levels. Good fundamental synth stuff that allows control over a main freq value (which could be entered via a MIDI notein).

For the graph part, it's really just to show that generating curves is straightforward. The presets disappeared when I pasted the patch (I guess this happens all the time? I didn't know that, too bad). Essentially it takes values 0 - 127 from an uzi and calculates the sine of each, after it goes through a scalar (to make the values more appropriate for sine). It's then scaled again (to change the height of the curve) and has an offset (to move the curve up and down). Try a range of scalars; an offset of 64 will put the curve in the middle of the graph.

What does it "do"? ;) Often a good question in Max, since these things can "do" whatever you want. I have it playable as MIDI notes, just as an example. So the first scalar determines how often the sine goes up and down, the second scalar stretches or compresses the curve, and the offset moves it up and down (transposition of notes).

Really it's just for experimentation and to show how to generate curves automatically. This way there's a certain level of control while generating values that aren't totally known, a kind of quasi-randomness that's fun to mess with. Again, once you see some of the possible curves, use a pattr on the parameters and you'll have tons of automatically-generated curves to access. The values can do anything you want, not just be MIDI pitches as I've got here... amp, FX, durations, mixing levels, brightness levels of a video, etc... it's up to you.

The key is the expr... with a more complex function there, or stringing several together, you can get pretty nutty with the curves you make. Also, I'm a big math dork ;-) so I'm pretty happy just seeing the results graphically. It's way cooler rendering the values in GL, but that takes a bit more work.

What i want to do is connect envelopes to the two parameters here,

but in current state, i dont get the parameters to "constantly uppdate" the freq value in my oscillators.

The divide only occurs when you change the left float. With pak output

occurs when you change either value.
