> DETUNE
This determines the detuning of osc 2 relative to oscillators 1 and 3. The subtle tuning varia-
tions between all the individual instruments in a string ensemble is a major factor in the
'warmth' that is associated with that sound – the same is true of many famous synth patches,
which use detuned oscillators to achieve a similar effect.
NOTE: Detune is affected in a subtle way by keyfollow – the higher up the keyboard you play,
the less osc 2 is detuned. This achieves a more musical result than a linear detune.
> KEY FOLLOW
This determines how MIDI note number affects the pitch of osc 2. At the default setting of
+32, playing an ascending chromatic scale (play every key in sequence, including the black
keys) will cause the pitch of osc 2 to rise in semitone intervals. At a setting of +64, playing the
same scale will cause the pitch to rise in whole tone intervals. A setting of 0 results in every
key sounding at the same pitch, and minus values will make osc 2 descend in pitch as you
play up the keyboard!
> SYNC
When switched to On, the wave cycle of osc 2 is forced to synchronise to that of osc 1.
Depending on the pitch of osc 2 the result can be a cold, hard sound with a lot of overtones.
Try sweeping the pitch (Semitone) of osc 2 for a dramatic demonstration of this effect.
NOTE: Tip: Try using LFO3 to modulate Sync Phase (see LFO Page).
> FM AMOUNT
This determines to what degree osc 2 is frequency-modulated by osc 1. The results will vary
considerably, depending on the interval between osc 1 and 2, but this will often create com-
plex timbres, which may sound quite atonal. Try using Sync as well for even more timbral
possibilities - the effect of FM can be more subtle when used in conjunction with oscillator
sync.
> FM MODE
This selects the waveform with which the frequency will be modulated:
> PosTri:
Modulates osc 2 with a positive triangle wave according to the pitch of osc 1.
