This is an approach to simulate the performance of a real theremin.
The 2 antennas are represented by 2 XY Pads, you can choose if you want to use the antenna or keys for both frequency and gate/volume. Keep in mind that if Amplitude Antenna is On, the volume is gonna be set by the Amplitude Antenna Y-Axis.
There are 5 different option for vibrato: Vibrato performance (you can set here the vibrato performance by drawing it in the graphic modulator), slow, medium, fast and random. You can also turn off the vibrato.
Thanks to bcrichards who helped me with the glide module.
