• Following such drastic augmentations to the modulation range, the sound will have
become uneven. In the lower and middle ranges, it sounds nice, but in the treble
range the FM intensity appears to be too severe. You can compensate for this effect
by setting the target Osc 1 Wave to be modulated by the keyboard position (kybd) in
modulation channels 5 and 6. This results in a keyboard scaling of the FM intensity.
• As the sound range is so vast (due to the 4 modulations), two modulation channels
are required to compensate for this. Set the lower slider halves to their lowest
positions. Good keyboard scaling is essential for any FM sound.
Tutorial Setting: FM Drive
Topic: FM with Drive and Filter-FM
You can dramatically alter the character of FM sounds by applying Drive and Filter FM.
The results are reminiscent of the feedback circuits of classic FM synthesizers.
• Check out different Drive and Filter FM settings.
• Lower the Cutoff Frequency of Filter 2 to 0. Envelope 2 modulates Filter 2. This
modulation routing is preset in the setting.
Tutorial Setting: FM DigiWave
Topic: FM with Digiwaves
In this example, a DigiWave is used as an FM modulator. This results in a bell-like
spectra out of only two operators. Normally, this type of timbre could only be produced
through the use of a larger number of sine oscillators.
In order to create a fatter, undulating, and atmospheric quality to the sound, the
polyphonic unison mode has been engaged. Filter and amplitude envelopes have been
preset to shape the sound.
• Check out the variety of DigiWaves, as FM modulation sources.
• Check out different Analog parameter values.
Tutorial Setting: FM Wavetable
Topic: FM with Wavetables
You can program the most vivid FM sounds when the modulation source “morphs”
between different Digiwaves. The morphing in this setting is controlled by LFO 2 in this
setting. The tempo of LFO 2 (and therefore the morph) depends on the sequencer
tempo (here: 2 bars).
• Set LFO 2 to different waveforms. Lag S/H (smooth random), in particular, should be
fun.
• Check out different FM intensities and Oscillator frequencies.
• Alter the modulation intensity of the first modulation channel (LFO2 modulates Osc2
Wave) and the LFO 2 rate.
