Seems kinda tricky. I would use two oscils for modulation.

The udo below is behaves as an operator, you can stack them like this:

a2 phoscil 0, afreq, ifn
a3 phoscil a2, afreq, ifn

See for example http://www.binarybrain.de/music/csd/phasemod.csd

opcode phoscil, a, aai

	amod, afreq, ifn xin

	isize = ftlen(ifn)

	aphasor phasor afreq
	ascaled = aphasor * isize
	atable table ascaled+(amod*isize), ifn, 0, 0, 1

	aosc = atable

	xout aosc

endop

Hi,

Not ideal, but you could use:
http://www.csounds.com/manual/html/downsamp.html
To convert the output of one foscil to go into the other. However,
it's probably better to implement all the modulation yourself from
oscillators.

Cheers,
Andres
