Simple math question
I replicated something I've seen on the pure data forum and something is really puzzling me
It's a simple ad envelope with the output going into a sqrt ,( the ad evelope mimicks the pure data line ~object going from> to over x time )
The ouput of the envelope is fed into a sqrt module which make the linear attack stage rise faster , then using a mul* to increase the range( obviously not used for the right speaker because of huge dc signal)
What I don't get is why there is an obvious downward pitchbend when feeding it into a sine function , while the envelope is clearly rising .
Edit , just noticed a mistake on the screenshot , the green and rex bounding boxes on the waveform view should be swapped , sine =green , envelope =red
Comments

Edit , I think I found it but not sure
The envelope going rom 01 is rising the pitch becase for the sine fuction it doesn' t really matter , iow it runs backwards .
Does that make sense ?

Now I'v got it ..( I hope )
The ramp sqrt does phase distortion
I compared it with ( cyclone pure data ) kink~ (phasor into kink~) which adds a variabe breakpoint to the linear ramp of the phasor
First screenshot shows phasor into sqrt~(upper ) and lower phasor into kink~ .
Second screenshot shows both outputs (left sqrt,right kink ) multiplied and into separate cosines .
The cosine when driven by kink ~ is obviously played a higher pitches before the breakpoint ( steeper rise ) and a steady lower pitch .after that ( when using mul*)
The sqrt ~ becasue of the conitinous rise has a fallen pitchbend
Always worked with phase distortion to distort ramps into lookuptables , kind of a surprise its capable of pitchbend

You are feeding it into a trigonometric sine function, not a sine oscillator...
The 'frequency' depends on the steepness of the envelope rather than the direction.
And if you are changing the steepness, the 'frequency' will change

I am aware that I fed it into a sine fucntion and not a sine oscillator :) , hence the lack of a frequency input .
I've used it enough for phase modulation ( only possible way in primary by use of ramp+ sine function )
And I also know that the frequency depends of the steepness of the envelope , it was just kind of suprising that a rising envelope gave a pitch bend down effect .
