superscope problem
hello, im sorta new to the superscope system but i do kn ow my maths (lol) im trying to simulate an x by y oscilloscope system with superscope, the type of thing where the left channel will move a dot left and right and the right channel will move the dot up and down. combining those two move the dot to a certain position. has anyone coded this before? im in dire need of somthing like this since im making a laser display which will do it litterally but i need a display on screen to compare the movements if anyone can supply equations for this id be most greatfull!

I'm not quite sure if this is what your looking for, but I made something simple

init:
n=1000;

point:
x=i*2-1+getosc(i,0,1)*0.2;
y=-i*2+1+getosc(i,0,2)*0.2 

 init:
n=1;

point:
x=getosc(0,0,1);
y=getosc(0,0,2);

this is sorta what i aim, not the effects shown but what the oscilloscope is actually presenting from the audio signal.

its a vector based audio to 2 tone image converter...

and that oscillo was drawing that image from a wav sound file...
