Currently I'm modulating the detune knobs, but am only getting a range of 24 semitones. Is there a way to modulate the pitch of each oscillator even further?

Alternatively you can modulate the Master Tune knob. This applies to all oscillators, and will give you a much wider range of modulation.

Cheers,

To widen the range of modulation you just add the mod to itself... I mean you repeat the modulation as much as you need it.

In the pic below the lfo modulates the osc 1 detune 3 times, and the range is extended by the same amount.
