TROUBLE SHOOTING

WARM UP
Due to the nature of analog circuits, you will want to let your XS warm up for about 15 minutes before
playing the unit. This allows the unit to reach its typical operating temperature, which will provide the
best tuning and performance.

NO SOUND?
First, check the power supply is plugged into the wall outlet and into the XS, and the XS is turned on
(power LED should be lit). Second, make sure the MIDI channel of the XS is set to the same channel
your MIDI keyboard or sequencer is sending data on. If MIDI notes are being received, you should see
the blue LED flashing in the Envelope 1 section (as long as no cable in inserted into the Gate In jack).
Third, make sure the Level controls in the mixer are turned up for the audio source you are using.
Fourth, make sure a cable is not inserted into the Amp In jack, or if there is, make sure it has a live
signal on it. Fifth, check that the volume control is turned up, and you have properly connected the Main
Out jack to your outboard mixer and/or audio system. And finally, check to see that the rest of your
audio system is working properly, by testing with another known working audio source.
Check over your connections and routings carefully. It’s often just a simple mistake that gets
overlooked. And occasionally both MIDI and audio cables do go bad, so try using different cables for
the same routings.

LATCHED NOTES
Should notes ever become latched or stuck where they continue playing, you can turn the unit off and
then back on again, and playback should resume to normal.
Common causes for latched notes might be due to the XS not receiving a proper MIDI Note Off
command, or the reception of too much MIDI data. It is always good practice to send only the MIDI
data to the XS that it responds to for optimum MIDI timing.

OSCILLATOR B’s PITCH DOESN’T SEEM TO CHANGE
Make sure the Sync switch is in the off position.

NOTHING HAPPENS WHEN I SWITCH THE LFO SYNC SWITCH ON
In order for the LFO to sync to a MIDI clock, it needs to receive a MIDI Clock from your master
sequencer, and it also needs to receive a MIDI Start command for syncing to begin.
Note: When the LFO is syncing to a MIDI clock and you adjust the Rate control, the phase of the LFO
waveform may sound off from what you typically think of as synced. If you stop playback on your
master sequencer and then restart playback, you will hear that the LFO realigns its waveform phase to be
“on-beat.”

THE FILTER DOESN’T SEEM TO BE VERY RESONANT
If the input of the filter is being overdriven, you will notice less resonance response in the filter. The
solution is to back off your levels in the Mixer section until the desired resonance amount is possible.

I HEAR POPPING OR CLICKING IN THE AUDIO OUTPUT
To reduce audible popping in the output, you may wish to slightly increase the attack/decay/release
times for Envelope 1 or 2. Popping may also occur due to abrupt changes in Velocity values controlling
the amplifier. Try dialing back the Velocity amount in the amplifier section.
