The FX Modulator section is a low-frequency oscillator that generates sub-audio range signals specifically for modulating effects parameters. Though it appears in the same location and has similar controls, it operates completely independently of the Main page Modulator section.

Speed- The Speed knob sets the Modulator speed, from 0.01 to 20 Hz (with Sync switch off) or from 8 beats up to 1/64th note triplets (Sync switch on). The LED above the Speed slider flashes at the current modulation rate.

Waveform- Selects the repeating pattern of the Modulator. Available waveforms are ramp, sawtooth, triangle, square, noise, and random (aka, sample & hold).

Sync- When the Sync switch is enabled, Modulator speed will lock to host tempo when using Atomika within DAW software, or to the current tempo in the top menu bar when using the standalone version.

Mod Wheel- This is a really handy, but potentially confusing feature, so don’t skim this section. If the switch is in the Off position, the Modulator is always “on.” Its effects will be immediately audible by moving the Modulator knobs in the Phasor, Flange/Chorus, Echo, and Reverb sections. Clicking to the On position enables control of Modulator depth with an external keyboard controller mod wheel. If the mod wheel is all the way off, Modulator depth is zero. This makes setting up a mod wheel to control effects modulation really easy. If it seems like the FX Modulator isn't working, check if the Mod Wheel switch is on.

Key Reset- Enabling Key Reset restarts the Modulator cycle monophonically if no notes are currently on and a new note is struck. If additional keys are played, the Modulator won't restart until all keys are released.
