Audio Damage Axon - Manual (Page 14)

the voice on and off at a rate equal to the frequency of the signal on the buss. This creates an effect similar to
the ring modulators found on analog synthesizers.
It is perhaps self-evident that the effect of both of the busses is easier to hear than it is to describe. The most
important point to remember as you experiment is that the voices are modulating each other. There are no
internal oscillators that generate the signals for FM and Ring busses. If no active voices have their FM Send
and Ring Send sliders positioned above their minimum values, there will be no signals sent to the busses and
you won’t hear any effect as you move the FM Receive and Ring Receive sliders.
FM Send/Receive
The FM SEND slider sets how much of the voice’s output is added to the FM buss. Moving the slider to the
right increases the amount that the voice’s signal contributes to the FM buss.
The FM RECEIVE slider sets how much the FM buss signal modulates the voice’s carrier oscillator—that is, how
much it changes the voice’s timbre by frequency modulation. If the slider is positioned at the far left the FM
buss has no effect on the voice.
Ring Send/Receive
The RING SEND slider sets how much of the voice’s output is added to the Ring buss. Moving the slider to the
right increases the amount that the voice’s signal contributes to the Ring buss.
The RING RECEIVE slider controls how much you’ll hear the Ring buss change the timbre of the voice. It
essentially acts as a level control. If the RING RECEIVE slider is at the far left, you’ll hear the voice unaltered
by the Ring buss. As you move the slider to the right, you’ll hear an increasing amount of the voice’s output
modulated by the Ring buss.
MIDI Only
If the MIDI ONLY switch is turned on (by clicking it—click it again to turn it off again), the voice does not
generate any sound by itself. Instead, only MIDI note on/off messages are transmitted by Axon. Since the
voice isn’t generating any sound, it doesn’t contribute to the FM and Ring busses either. Turning on the MIDI
ONLY switch can save a little of your computer’s available CPU resources if you’re using Axon exclusively to
control another synthesizer via MIDI.
Since the AudioUnit version of Axon does not transmit MIDI, the MIDI Only switch does not have any useful
effect when Axon is running in an AudioUnit host.
