    Does anyone know of a way when amplitude modulating the XR2206 IC to
    change the attack and decay rate?

    Use a ramp? Just have your AM voltage follow the attack/decay curve you
    want.

    Good Luck!

    I was hoping to use a sine wave to get a siren-like effect.... The
    CD4046 can be frequency modulated that way, but I was hoping the 2206
    could be amplitude modulated like that.

    I looked at the 2206 data sheet, and it seems to have an AM input, which
    is what your original post was about. I didn't bother to look at FM,
    which is what a siren is. So, you put your Siren modulation to the FM
    input, and your attack-decay-sustain-whatever curve into the AM input.

    Good Luck!
