The Moogerfooger® CP-251 Control Processor makes an ideal
companion to the Voyager OS. The CP-251 provides an LFO with
two waveforms (Triangle/Square), a Sample & Hold circuit with two
outputs (stepped/smooth), a Lag Processor, a Noise source, a Mixer
and two active Attenuators. The combination of Voyager, VX-351and
CP-251 is very much like having a small Modular synthesizer. The
nice thing is that the most basic connections are already made in the
Voyager, so the CP-251 and VX-351 add an extra level of modulation
signal fl exibility.
Here are some possible confi gurations for using the CP-251 with the Voyager. Grab some 1⁄4” patch cords
and try these ideas!
1. Simple confi gurations using the LFO
The LFO in the CP-251 can be used for common modulations such as vibrato, tremolo, auto-pan and
modulated fi lter effects, freeing up the Voyager’s LFO for other uses.
To try any of the examples shown below, begin by connecting the CP-251’s LFO Triangle output to an At-
tenuator Input, then follow the example to complete the modulation routing.
To create Vibrato:
Using a patch cord, make a connection from the CP-251 Attenuator Output to the Voyager’s PITCH
jack. On the CP-251, set the LFO RATE control to 6 Hz (about 1 o’clock), and adjust the ATTEN-
UATOR control to about ‘0.5’ on the dial (a very low amount). This confi guration will produce a
constant mild vibrato. Setting the CP-251’s LFO RATE control considerably higher will result in wild
FM textures.
To create Tremolo:
Using a patch cord, make a connection from the CP-251 Attenuator Output to the Voyager’s
VOLUME jack. On the CP-251, set the LFO RATE control to 6 Hz (about 1 o’clock), and adjust the
ATTENUATOR control to ‘10’ on the dial. This will produce a constant tremolo effect. Adjust the
LFO Rate to taste. For a sharp, volume-chopping effect, use the CP-251’s LFO Square wave output
in place of the LFO Triangle out.
To produce Auto-Panning:
Using a patch cord, make a connection from the CP-251 Attenuator Output to the Voyager’s PAN
jack. On the CP-251, set the LFO RATE control to 6 Hz (about 1 o’clock), and adjust the AT-
TENUATOR control to ‘10’ on the dial. This will produce a constant panning effect. Adjust the LFO
Rate to taste.
