Ableton operator is a great FM synth with lots of options.
Using Phaedra as my main sequencer and setting up VEL > OSC is operator allows me to draw in pitch data using velocity which is then mapped to the pitch in operator. You can also assign velocity to filter frequency and other settings. Using this setup allows me to draw in pitch data rather than using the note data in phaedra, its not as accurate but its quick and dirty and good for live setup or jamming.
You can see it setup below
I’ve made a bunch of operator patches that get sound changes from velocity changes – you can download the patches here
