oscillator 2 is fully the ring modulation result of oscillator 1 and oscillator 2. In middle position
the output is mix of oscillator 2 and the ring-modulation result of oscillator 1 and oscillator 2
(this is what you find in some synthesizers as AM = Amplitude Modulation).
Mixer
The upper dial in the Mix section is used to set the relative output volume of each oscillator
module. When the dial is set to 1 (i.e. it is turned all the way counter-clockwise) the output
signal consists entirely of oscillator 1. When the dial is set to 2 (i.e. it is turned all the way
clockwise) the output signal consists entirely of oscillator 2. The mid position provides an
equal mixture of oscillator 1 and oscillator 2.
The lower dial is the “noise” parameter that allows to mix gradually some noise
to the two oscillators mix. Turned fully left no noise is added, turned fully right the oscillators
are suppressed and only noise is audible. The generated noise is white noise, pink noise or
brown noise and can be set by selecting one of the three color dots below the dial.
Filter
The Alpha's filter module is located right of the oscillators. This also reflect the signal flow,
which is from the Oscillators into the Filter.
The “drive” (or saturation) dial on the left can be used to overdrive the Alpha's filter. This can
be used to produce a distorted sound which depends on the amount of drive applied and on
the basic waveform. It also depends on the Level of the signal that comes from the
oscillators: so if you for example amplitude modulate an Oscillator with an LFO via the
Matrix, this will not only change the amplitude but also the distortion (if applied).
Below the drive there is the filter “fm” dial and filter fm source selector. With the dial the
amount of filter cutoff modulation is adjusted from no modulation when turned fully left to
maximum modulation. As the modulation source is in audible range we have a true Cutoff
Frequency Modulation (Cutoff FM).
