OSC 23 FM Level – increases the amount that oscillator 3 is Frequency Modulated by oscillator 2, making
the sound more metallic
OSC 2>3 FM ADEnv – increases the amount that the Frequency Modulation (set in the previous option)
is modulated by the AD Envelope (envelope 3 of the Xio – see the Envelopes section for details). This allows a
sound with more interesting harmonics at the start to be created
OSC 2>3 FM Lfo1 – allows the FM set in the previous FM Level option to be modulated by LFO 1
OSC Fixed Note – sets a fixed note (the same pitch) to be played by every key on the Xio. A 0 setting has no
effect. 1-127 set the corresponding MIDI Note value
The remaining Oscillator controls can be found in the Pulse Width and Mixer Menus.
