At a patch level the SHIFT button can access two more controls for each effect (as there are only two control dedicated knobs), oscillator panning, modulation LFO assignments, pitch bend ranges and so on. Speaking of the SHIFT button, if something doesn't have a dedicated control then some combination of this and another control will access it. This extra layer of control comes courtesy of the Modulation lever (ie, the vertical motion of the pitch bender) and, with the help of the SHIFT button has its own waveform and speed and can be assigned to alter any of the LFO parameters. The LFO can itself be modulated further by the seemingly invisible Modulation LFO. The LFO features six waveforms (triangle, sine, sawtooth, square, S&H and random) with a rotary speed knob, a tempo sync button, flashing speed LED and sliders for the LFO assignment: Fade Time, Pitch Depth, Filter Depth and Amp Depth. "The layout is so 'left to right' intuitive that you can get straight into tweaking and playing the second the Gaia is plugged in."Īfter Tone selection come the LFO controls, followed by the OSC (oscillator) section, the Filter controls and ending with the Amp section.
There is also a Tone Copy button to duplicate tone settings to speed up editing and patch creation.
Tones can be edited singly or together by pressing and holding the appropriate Tone Select buttons. You start on the left with the Tone selection buttons that select and operate the three Tones (effectively three synths, each with its own oscillator, LFO, modulation LFO, filter and amplifier).
