Finding a faulty voice
If one voice is detuned
or muted then most commonly a voice card is defective
There is no reason for worrying!
If one of your voices seems to be defective,
there is absolutely no reason for worrying! We have a lots of experience
at Synthex synthesizers and we like to help you! In the very most cases
there isn´t any need to send the whole Synthex to Virtual Music´s
synthesizer service center. We only need your defective voice card,
which will be tested and repaired in our internal testing system.
Inside of the synthesizer
you can find 4 voice cards. They are responsible for 8 analogue voices.
Yes, you are right: Each voice card can generate two independent
First of all you need to find out which of the 4 cards are defective. BUT
FIRST: Unplug the power cable!
the 4 screws and lift the panel. Caution: Proceed only if you have
knowledge about electronic equipment. One wrong handle (e.g. at the
power supply) can be lethal! In case of doubt please
engage an expert!
touch the electronic parts inside the Synthex! Replug the power cable,
power up the Synthex and choose a sound program. During playing on the
keyboard you can see some red LEDs on the voice cards. They glow
corresponding to the played voice. Play as long as you have found the
defective voice card
Power down the synthesizer
and disconnect the power cable. Open the two big screws and remove
card and wrap it into antistatic foil first. If the card is somewhere
in the middle, deinstall the upper cards, too. But caution: Keep in mind
which of the cards the defective one is. Else: The procedure of
"finding the faulty card" was useless... ;-)
If you need technical assistance or
support, please contact us. The Synthex is a very complex and sensitive
device and should be treated with respect.
If you want us to repair your defective channel
card, please get in contact with us before
sending any equipment. After clarifying all details please fax us the completed
order form for synthesizer service , or put it into the card´s
Other problems with your Synthex?
Of course we can repair
other defects fast and effectively, too. If you have any problem with your
synthesizer, please contact us. We are happy to help you!

Does your Synthex suffer from
poor MIDI timing or stuck MIDI notes? No worries! The basic principle: Elka´s Synthex
doesn´t like MIDI-realtime-messages (timing
clock, active sensing, etc.)!
As soon as your MIDI sequencer "annoys" the Synthex with realtime messages, the Synthex responses with a very
bad MIDI timing.
In some extreme cases the notes won´t be triggered or get stuck.
This is a nasty behaviour but not a damage or bug of the Synthex´s
You can avoid these effects: Simply disable any realtime messages on
your sequencer´s MIDI port which feeds the Synthex. Take care that the
Synthex will receive only Note-On and Note-Off messages and everything´s
Additionally it is recommended to use just the Synthex on that MIDI-port
and no other MIDI devices. Just avoid any daisy-chaining of MIDI
devices. This is because the Synthex has to check and verify each single
MIDI message (no matter who is the receiver of that data) and this makes
the internal processor very sloooooooow...
Synthex: Original Factory Presets
By chance we got the original Synthex
factory presets and we´d like to share them with you. These sounds
are different from the internal ROM presets and are very
sought-after. Please use
How do the
sounds go into the Synthex?
Open the file in
your computer´s favourite media player (e.g. Windows Media Player)
Synthex´s backside jack "FROM CASSETTE" with your computer´s audio
switches "WRITE ENABLE" and "LOAD" on the Synthex´s backside
All panel LED´s are
dark now; the sound production is deactivated
Now press the
button "LOAD" which is the double function of the button "WRITE"
Start the media
player and send the sound information to the Synthex
fine the bank select LEDs start lighting; one after the other in a
Blinking LEDs or
dark LEDs show that the transfer was incorrect, maybe the sound
level of the sound file was too mellow or the cable connection was
bad. Just check and try again
If everything is
fine switch off both switches on the backside of the Synthex
CAUTION: If you
transfer the patches from your computer to the Synthex then you will
loose all previous stored patches in the area "MEMORY"!
