RoomSense
Did you notice that little hole on the front of the unit? It’s a microphone!
It’s there for two reasons:
1. If you beam in a preset that contains Harmony or HardTune eects and
you’re not using MIDI, keyboard audio or an Aux music source to guide key/
scale, the mic will listen for chords in the room (like a nearby guitar) and try
to gure out key and scale from that! Pretty cool.
a. RoomSense is the most unpredictable of the key/scale trackers, since
the room dynamics and chord information is most easily obscured using
this mode. That said, it can be quite eective in specic situations,
like placing the unit on top of an acoustic piano.
2. If you don’t plug in a microphone and have headphones connected, you
can sing into the onboard mic. It’s a great way to practice with virtually no
other equipment.
a. If you’re singing into the RoomSense mic, the Main Outputs *there isn’t
a Mic Out on VK* will be muted to prevent feedback.
AUX Input
When you have a music player connected to the AUX jack, and nothing is
connected to the MIDI or INST jacks, any incoming chord information from the
AUX input will be used to determine key/scale for Harmony or HardTune.
(When both the AUX and MIDI/INST jacks are used, the MIDI and INST connections
take priority for detection of key/scale)
You will hear the AUX input mixed with your Mic input (vocals). If the AUX is
too loud or too quiet, use the volume control on the music player to create the
appropriate mix with your vocals.
Audio from the AUX input is slightly delayed from input to output so that we
can better detect chords. This won’t have any eect on music you’re singing
or playing along with, but it does mean this input isn’t intended to support
instruments that you’d play live. They’d feel strangely “laggy”. Use the INST IN for
live instruments.
If you do have a keyboard connected to the MIDI or INST IN jacks, they will be
used for the key detection, and the AUX jack will not be delayed. This way the
AUX input can still be used for a click track, drum machine, etc.
Aux to Main Out
Sometimes, you’d like to have a signal from the Aux input guide key/scale, but
you don’t want that Aux signal mixed into your main outputs. If you’d like to
remove audio from Aux to the main out, simply press/hold the Headphone
button while connecting your Aux (⁄") cable.
This parameter resets each time you unplug and re-plug the Aux cable or if you
power cycle the unit. We don’t save this parameter because it’s not immediately
obvious how you’d “toggle” things and we don’t want to trap unsuspecting users
in a mode they can’t nd a way out of.
Dimming the Buttons
The buttons on your PERFORM-VK are designed to be pretty darned bright so you
can see them clearly in an outdoor environment. If you’re playing inside, you may
not want to tan yourself with their brilliance.
To dim/brighten the buttons, press and hold the SET button while turning the
Control Knob. Turning the knob to the right increases brightness and turning to
the left decreases brightness.
