Lisajous Oscillator

I want to create a lisajous oscillator with one oscillator on left channel and another on the right. I need to control freq and phase.
I am a novice so having trouble with syntax after using the audio system design tool (which is quite simple I think...just two waveform mods).
thank you for any input.

Sounds like you're making a laser controller, too. I recommend watching 'Note and Volts' Teensy synth tutorial series. I've found it to be extremely helpful. Dave provides excellent instructions, as well as sample Arduino code for the Teensy.
In his Part 2 video, he introduces Pure Data, a graphical design app for MIDI In/Out control, which can be used with a DAW, like Ableton Live.
Within one day, I managed to modify his code to program 4 quadrature waveform generators, with x/y mixers and an LFO for AM. It came together so fast that I haven't even had time to solder the Teensy and audio board together to test it out. But, Ardiuno says there's no errors in my sketch.
I'll find out tomorrow.
Hope this helps to get you started.
