6. The Instruments: The Synth section
The three different FM algorithms in the Nord Stage: one, two and three
oscillator FM with feedback. The feedback is not active in all algorithms.
The Timbre knob controls the FM and feedback amounts. When you turn the knob, all modulations
are increased simultaneously. The number of harmonics, and their intensity, increase proportionally
to the FM amount. As usual, the Timbre parameter can be modulated by Velocity or the Modulation
Envelope, and it can be Morph controlled by any combination of wheel, aftertouch and pedal.
Each algorithm comes with a number of preconfigured frequency ratios. Depending on what kind of
sound you want, choose from the different combinations available and you have many interesting FM
sounds at your disposal. When a new wave is selected, the M
