Parameter editing
Osc1 Keytrack Keyboard tracking on/off. When the function is enabled, the pitch of the
Osc2 Keytrack oscillator varies according to which key is pressed: in this case, each key
corresponds to a note. By disabling this function, the frequency of the signal
generated by the oscillator is always fixed regardless of the key pressed and
established with the Osc1 Coarse (or Osc2 Coarse) and Osc1 Fine (or Osc2
Fine) parameters.
Values: OFF, ON
Osc2 Sync Activation
(OSC.2 only) synchronization of Osc 2 with Osc 1. If
synchronized, every time the waveform of
Osc 1 returns to its beginning, that of Osc
2 will also be reset (i.e. to the beginning of
its cycle) obtaining thus a more complex
waveform.
Values: OFF, ON

FILTER section

Synth-8 features low-pass, band-pass, high-pass and notch
filters, with slope at 12 dB or 24 dB per octave (6 dB and 12
dB for band-pass and Notch filters), with adjustable
frequency, resonance, distortion and other parameters. The
filter frequency can be modulated via the key velocity and/or
the AD envelope of the MOD ENV section (page 13).
To access this menu, in the EDIT SYNTH-8 screen (page
6), place the cursor on the FILTER field and press the data
entry dial.
NB
The table below shows all the parameters available for the FILTER section. The knob or button
that allows direct control from the panel is shown under the name of the parameter.

Description
Filter cutoff frequency. Depending on the filter
type, the cutoff frequency takes on different
meanings; refer to the description of the Filter
Type parameter regarding the effectiveness of
the filter in relation to the cutoff frequency.
Values: between 0 and 127
Resonance coefficient. The resonance causes an enhancement of the
frequencies around the cutoff frequency. By increasing the resonance, a
greater selectivity of the frequencies that are affected by the enhancement
is obtained.
Values: between 0 and 127
