Thank you both for the reply. I'm ok for now with a straight lfo in this specific case but knowing how to use an osc as opposed to an lfo will probably be useful in the future. 

To Dave, the waveform was already positive but your suggesting worked great, just in reverse. 

    instr Ramp
aSig =  lfo(2, 20, 4)
    out aSig + -1
    endin

Thank you both, I very much appreciate the help.

you can combine all in a single expression

aSig =  lfo(2, 20, 4) - 1

Thank you for the tip Victor. I started learning to code just over a month ago and have never studied programming so this is all quite new to me. Tips are always welcome!
