cho rda and sin and cos

[dkleinjans]

Hi,
I'm trying to understand the cho rda command. In the end, I want to make a quadrature sine wave for a chorus, with four waves 90 degrees offset. I created a simple program to try to see the effect of the sin and cos outputs. The input to the FV-1 is a sine wave from a frequency generator. The dacl and dacr outputs viewed on a scope are identical, which surprises me. I expected they would be 90 degrees offset. What am I missing?
Thanks for any help.

I believe you missed the "reg" in the
cho rda, sin0,cos|compc,mchodel^
line.

Well, that was easy.
Thank you, Frank.
