Setting Oscillator 1 Frequency - Octave/Semitone/Cent
By clicking the corresponding up/down buttons you can tune, i.e. change the frequency of Oscillator 1 in three ways:
D In Octave steps
The range is 0 - 9. The default setting is 4 (where “A” above middle “C” on your keyboard generates 440 Hz).
D In Semitone steps
Allows you to raise the frequency in 12 semitone steps (1 octave).
D In Cent steps (100th of a semitone)
The range is -50 to 50 (down or up half a semitone).
Oscillator Keyboard Tracking
Oscillator 1 has a button named “Kbd. Track”. If this is switched off, the oscillator pitch will remain constant, regard-
less of any incoming note pitch messages, although the oscillator still reacts to note on/off messages. This can be
useful for certain applications:
D When Frequency Modulation (FM - see “Frequency Modulation (FM)”) or Ring Modulation (see “Ring Modula-
tion”) is used.
This produces enharmonic sounds with very varying timbre across the keyboard.
D For special effects and non-pitched sounds (like drums or percussion) that should sound the same across the
keyboard.
Using Oscillator 2
You activate Osc 2 by clicking the button next to the text “Osc 2“. Setting oscillator frequency and keyboard tracking
is identical to Oscillator 1.
28 Similar to 27, but with a slightly different character.
29 This waveform has complex, enharmonic overtones, suitable for metallic bell-type sounds.
30 Similar to 29, but with a slightly different character. By using FM and setting the Osc Mix to Osc 1, this and
the following two waveforms can produce noise.
31 Similar to 30, but with a slightly different character.
32 Similar to 30, but with a slightly different character.
