Ring Modulator Operation - Horst MIDI Wave-Theremin MWT-01 Manual

Ring Modulator Operation:

The 'MODULATE' position of the instrument selector has 3 carrier-
frequency generators available: sine (P1), triangle (P2) and square (P3). The
carrier frequency is controlled via the theremin antenna and the octave-skip
parameter.
The 'MODULATE' position also has 3 raw oscillators available: triangle
(P1), square (P2) and needle (P3). Each raw oscillators can be independently
adjusted in pitch and volume. The stereo inputs of the theremin are
combined and added to the internal generators and the mix is then send to
the ring modulator input.
Ring modulation is performed by multiplying each of the 3 carrier wave
forms (sine, triangle, square) with the incoming audio signal (external signal
+ raw oscillators). The resulting 3 output signals can be individually panned
and mixed. Setting the mode selector to position 'PAN' allows you to adjust
pan for each output. Setting the mode selector to position 'TONE' allows
you mix the 3 output levels as desired.
Setting the mode selector to position 'CONTROL' , Carrier octave skip (P1)
and carrier frequency (ring mod pitch P2) can be adjusted. The pitch of the
internal oscillators (Raw Oscillator Pitch) can be shifted up and down with
knob P3. (Hint: set this parameter (P3) to max (or middle) before setting up
the pitch of the 3 internal oscillators).
When not using the internal audio generators (only external signal), the ring
modulator modulates the external signal by multiplying each of the 3 carrier
frequencies (sine, triangle, square) with the external signal.
