Erica Synths SYNTRX II, User Manual

Page: 6 / 27

OSCILLATOR 1 is primarily an audio rate oscillator and without an external CV
applied, it generates sine and pulse waves at frequencies from approximately C0
to C8. The OCTAVE switch allows for offsetting the oscillator three octaves up or
down. The TUNE knob allows for fine-tuning the pitch of the oscillator in an
approximately two octave range. Each wave has manual and CV control over the
waveform. By turning the SHAPE knob, the pulse wave changes pulse width, while
the sine wave changes shape from pure sine in the 0 setting to inverted sharkfin
when turned counter-clockwise and shark fin when turned clockwise.
Moreover, if OSCILLATOR SHAPE CV is applied to the relevant matrix input, the
OSC1 SHAPE switch determines which wave is being modified by the incoming
CV. In the middle setting, both waves are shaped, in the left setting pulse width
modulation is applied, in the right setting the sine wave is shaped. Please note
that incoming CV is added to the SHAPE knob position.
Each waveform has its LEVEL control and each wave is sent to an individual
matrix input. This is very handy if you design drones and wish to send each wave
to an individual output.
Oscillator 1 is controlled via the CV1 input, and an external CV is added to the
TUNE/OCTAVE knob setting.
THE “MODULES”
As mentioned above, using the matrix patchbay on the SYNTRX II, you can build patches and achieve unconventional modulations. In order to fully
understand the functionality of the SYNTRX II, let’s take a closer look at the individual “modules”.
