OTHER CAPABILITIES
PROCESSING EXTERNAL AUDIO
The Revolution provides an audio input for processing external sounds through the internal filter,
amplifier, analog overdrive stage, and the DSP effects section.
Here we are going to filter audio coming from a MIDI sound module which is being played by the
Revolution’s sequencer. However you can process any external line level audio signal in the same
way. If you are wanting to process turntable, guitar, or microphone sounds you will need to pre-amp
the signal to a standard line level before connecting it to the Revolution’s input.
For this setup, connect the MIDI OUT of the Revolution to the MIDI IN of the external sound
module. Use a 1/4” mono audio cable to connect the main output of the sound module to the FILTER
AUDIO IN jack on the Revolution. Setup the Revolution to play the external sound module as
described on page 30.
When the Revolution’s sequencer begins playing patterns, you should hear the sounds of the external
sound module being processed by the Revolution. Notes must be programmed into the Revolution’s
sequencer in order for the amplifier to open up and allow sounds to pass through to the output. By
placing a bunch of 16 th notes into a sequence, the external audio becomes gated. If you wish to
process the external audio without this gating effect, create a simple pattern with a loop point and
glide set on step 1 of the pattern, and play this pattern when you want the external audio to pass
through to the output.
You will notice that the audio input of the Revolution is very sensitive to normal line level signals.
This is so you can overdrive the filter input easily with a line level signal. If you do not wish to
overdrive the filter’s input, turn down the volume of the external sound module until the processed
signal is clean and without distortion.
