Detune: [0…50] sets the amount of detuning between the three oscillators. The detune function
increases oscillator 1 pitch and decreases oscillator 2 pitch from 1 cent to 50 while leaves the oscillator 3
pitch untouched.
FM:[0…1022] sets the amount of FM depth, Zero means
disable. (Coarse Soft Knob E1, Fine E3)
FM is located in Voice section Page2. [E3] soft knob changes
value ±1 step and [E1] changes it ±10 steps.
Oscillator 2 Triangle signal always modulates oscillator 1 frequency (you cannot change the modulator
waveform here it is hardwired internally). Varying the pitch of oscillator 2 regarding FM depth will result
in frequency modulation of oscillator 1. Except the pitch, other settings of oscillator 2 does not affect on
FM function. For the best result Square should be selected as waveform in oscillator 1.
Drift:[0…127] sets the amount of Analog Drift. (Soft Knob E4)
Although the Xenophone’s oscillators are analog but the main pitch is controlled by a microprocessor
(based on digital tuning word not voltage) which makes the synth always in tune. Analog drift detunes
and modulates oscillators in micro-cents range. If you want to hear the effect of analog drift you should
use more than one oscillator and set the [Phase Reset] parameter to Free-run.
Sync: [Off, On] enables/disables Hard Sync. It synchronizes fundamental frequency of oscillator 1 with
frequency of oscillator 2, producing a “hard sync” effect. In order for synchronization to occur oscillator
2 must be set to some frequency preferably lower than the frequency of oscillator 1.
Phase Reset: [On, Free-run] when “on” forces oscillators to start at specific phase (usually zero) every
time a new note is played. Each Oscillator has a dedicated phase parameter that represents the starting
point in waveform. If OSC1 Phase and OSC2 Phase have the same value, [Phase Reset = On] forces them
to be phase synced. In some sounds like percussive or bass it helps to increase punch and overall audio
level specifically when the waveforms and settings on both oscillators are the same. (Soft Knob E3)
In Free-run mode the oscillators are working freely and the Note-On message does not reset the phase.
In most of the analog synths, oscillators are working in Free-run mode. You can get the best result for
creating vintage synth sounds and fat brasses Using Free- run mode + Analog drift at the same time.
Analog drift is an algorithm which emulates the analog circuit components tolerance, temperature
effect and power supply noise. These flaws caused instability and tuning issues in old analog
synthesizers that used voltage based pitch control system. On the other hand and in a magical way
these flaws have a significant role in warmth and fatness of the sound when more than one
oscillator is used in the patch.
