integrator. In “layman” terms, it means that the triangle core waveform is
not perfect, it is a bit “skewed”, which gives it and the sinus wave a slightly
richer harmonic content.
Each oscillator has 3 parameters. The big [FREQ] knob adjusts the pitch in
semitones, from C0 to C8. The [DETUNE] knob has a range of two
semitones, with a pitch perfect 440Hz tuning in the middle.
The [WAVE] parameters smoothly fade from sinus, to triangle, to square
and nally to sawtooth wave. You basically go from the dullest of sounds to
the richest in terms of harmonics.
The two mod parameters give you additional sound design tools : the
[SYNC] key synchronizes the wave cycle of oscillator 2 with oscillator 1; the
[TZFM] parameter modulates the frequency of oscillator 2 · the carrier ·
with oscillator 1 · the modulator ·. It is analog thru-zero frequency
modulation, which has a very rich distinctive sound.
Finally you can adjust the amount of both oscillators fed to the lter with
[OSC1] and [OSC2] parameters. At high gain, the oscillators overdrive the
lter, so you can also use this parameter creatively.
Although limited compared to other big monosynths (only 2 oscillators ?!
No noise ?! What is this ?), this oscillator block allows for a huge landscape
of timbre. This can range from subtle bell-like sounds to very harsh
saturated noise. All this without even touching contextual modulation.
Adding the latter makes for a very complex oscillator system.
Just a simple example : use the X-Modulator at audio rate on the Freq
parameter of both oscillators - you get a 4-operator hybrid FM synth (for
normal people, this translates to: “You can do some pretty cool stu with
this synth”).
Oscillator Sync
I’m lazy so here is the wikipedia denition : As one oscillator ·
the master · nishes a cycle, it resets the period of another
oscillator · the slave ·, forcing the latter to have the same base
frequency. This can produce a harmonically rich sound, the
timbre of which can be altered by varying the synced
oscillator's frequency. And here is a nice schematic with
sawtooth wave example.
