Congratulations to your choice of a Gwerder Digital Accordion
We are sure, that after you have read this manual, you will be able to manage this
superb instrument without any problems and you will get the best out of it.
This Digital Accordion is the product of 8 years experience in the field of electronic
keyboard instruments for live musical performances.
Our digital accordions have been able to compete in recent years in the rough live
operation successfully and reliably, but also for musicians who arrange their own
pieces. It’s also excellent for students who want to practice at rest with the
headphones.
The accordion has a full range of advanced operations, but is very easy to handle, so
you can start making music without much preparation.
We wish you lots of fun with your digital accordion.

Safety measures
Copyright notice
- Read the instructions carefully.
- Make sure that the power cord is not bent, twisted or squeezed.
- Don’t put the instrument to extreme conditions such as high humidity or rain,
high temperatures, direct sunlight, excessive vibration or dust.
- Never touch the power supply/charger with wet hands.
- Either the accordion nor the adapter/charger may be altered in any way.
- Do not attempt repairs on the instrument. To avoid electrical shock, do not
open the casing. Otherwise your warranty will expire.
- The instrument can be very loud. Be considerate of your environment.
- Note for models with built-in Ni-MH battery: It may only be connected with our
original charger. The built-in Ni-MH battery is very sensitive, but requires no
major attention, as our charger monitors the entire loading process. Failure to
observe this requirement will void the warrenty.
- The power supply/charger will not be set to the voltage. It has an automatic
multi-area input (100 – 240 V 50/60Hz)

Save and storing of sounds
Loading Registers + Masterbar
MIDI-Out channels
If the instrument is adjusted to your taste you can store it in bank “B”. Push
the desired register on your accordion and release the button only when a
sound (Ping) occures. Now all settings will be overwritten on the memory
space in “B”. This process can be repeated on all memory spaces as often as
you wish.
Attention: When switching on the accordion, the parameter of memory space
1 will be selected automatically.
The bank “A” is set by the producer and can not be changed. So you have the
possibility of 60 different settings.
With a short touch of the desired register (memory space) only the 1. treble
voice is loaded and is ready to be played. With two short pushes of the
desired register, you will get the entire memory space of all the 6 parameters
(treble 1+2, bass 1+2, chord 1+2.
Please note: switching on the accordion, it will always load the parameter of
memory space position 1 A.
With the masterbar you can switch between the two previously selected
registers back and forth. It’s in each case only the first treble voice chosen.
The bass voices remain unchanged.
The MIDI-Out channels are assigned as follows:
Channel 1 treble 1. voice
Channel 2 chord 1. voice
Channel 3 bass 1. voice
Channel 4 treble 2. voice
Channel 5 chord 2. voice
Channel 6 bass 2. voice
