VIRTUALIZER PRO DSP1024P
3.4 Using the VIRTUALIZERPRO as an effects device for instruments
With its extensive MIDI implementation the VIRTUALIZERPRO can also be used, for instance, as a multi-
effects device in a guitar rack. Of course, you can connect it up in both stereo and mono. The following hints
illustrate the VIRTUALIZER PROs versatility if used with a guitar amp.
Fig. 3.3: Connecting the VIRTUALIZERPRO to a guitar amp (send/return-mono)
Basically, the VIRTUALIZERPRO should be inserted between the preamp and the power stage. Almost all
guitar amps have an insert or effect loop to send the preamp signal of the guitar amp to the audio inputs of the
VIRTUALIZERPRO. The VIRTUALIZERPRO processes the preamp signal and sends it back via the guitar
amps return bus (power amp in), from where it is routed to the power stage. When you use a stereo rack
system for amplification, you can wire the VIRTUALIZERPRO in stereo. Connect the preamp to the audio
inputs of the VIRTUALIZERPRO, and the audio outputs (left/right) to one channel each of the power amp (left/
right).
+ Since most guitar amps only have a serial insert loop, you should make sure that the
VIRTUALIZERPRO is set to Mix Internal mode. In this mode you can control the effect intensity
applied to the guitar signal. However, if your amp features a parallel effect loop which allows
for adding the effect-signal portion (similar to an aux path in a mixing console), we recommend
that you use the VIRTUALIZER PROs Mix External mode. In this case, the effect intensity
present at the output of the VIRTUALIZERPRO is 100%, and you can use the effect loop to
determine the amount of effect added to the guitar signal.
Instrumentalists can benefit from a variety of advantages offered by the VIRTUALIZERPROs MIDI
implementation. For example, you can use a MIDI footswitch board, e.g. the BEHRINGER MIDI FOOT
CONTROLLER FCB1010, to send program change commands via MIDI. Connect the MIDI OUT jack of your
MIDI board to the MIDI IN jack on the VIRTUALIZERPRO. If the VIRTUALIZERPRO fails to respond to the
program change commands sent from the MIDI board, check the MIDI channel settings. Consult the users
manual of your MIDI board to find out on which channels program change commands are transmitted (usually
in Omni mode). Set the MIDI channels appropriately in MIDI mode (see 2.5) and enable the VIRTUALIZERPRO
to receive program change commands.
If your MIDI board allows you to transmit MIDI controller data, you can even change parameter settings via MIDI
while playing. For instance, you can freely change the effect intensity from 0 - 100% while playing (Contr. 27,
Value 0 - 100). Set the controller for Mix-Internal mode (Contr. 30, Value 0) so that it can be used to increase
the effect intensity. In this way, guitar solos can be enhanced with chorus and delay effects, while the effect
intensity is gradually reduced when playing rhythm. You can even control the function of the IN/OUT switch to
bypass the VIRTUALIZERPRO when an unprocessed signal is needed. Basically, all MIDI devices that are
capable of transmitting MIDI controller commands, e.g. keyboards/sequenzers, will allow for using these
features.
