The price of an AKKOtune compact tuning table sometimes leads to discussions. Perhaps it is better to know that more than 600 individual parts have to be found, purchased, stored, manufactured, assembled and made to work before the tuning table is finished. All of this is not mass-produced, but made to order.
You can imagine that this is a lot of work that takes time, not to mention the fact that the development work has to be done first. The price for the system should actually be a lot higher. The reason why it is not is that it is also intended to be used by those who do not have so much capital at their disposal. Nevertheless, there is always the possibility of discussing the conditions for a purchase. I look forward to hearing from you.

the videos for ATB and the button hold-down are online on YouTube. A video showing the AKKOtune bandoneon in action will follow. The price list is also ready and can be found in the download area.
November 2024
The AKKOflip accessory for bandoneon gets a successor: AKKOtune Bandoneon - ATB.
It is designed in such a way that even the largest sound boards with the reed plates can be easily inserted into the turning frame (mounted on an adapter plate).
ATB is primarily intended for tuning bandoneons, Chemnitzer concertinas, concertinas, etc., i.e. for all instruments that have the reedplates on a sound board.
The new feature is the equipment of the device:
The BlowBox and control unit are located in the base of the ATB. So you don't need any other device for air flow generation and control, such as the AKKOtune compact.
The turning frame is securely pulled onto the seal of the base frame by 8 magnets; this ensures that the resonance chamber is securely sealed airtight. The BlowBox generates positive or negative pressure in the resonance chamber, as with a bellows. The pressure generated is displayed electronically on the control panel.
The magnets are switched on at the front. When switched off, the turning frame with the mounting base is simply lifted up, turned to any required position and replaced.
ATB will be available in three versions: With and without built-in microphones, and with an additional chromatic tuner to have an immediate display of the sound being played.
The device is approx. 30 cm high. The square turning frame with an edge length of 47 cm lies on top of it.
Power is supplied via an external 12V DC power supply unit.
By the way: In addition to the usual options such as foot switch and USB connection, there is also the option of making your own adapter plates to enable the tuning of reed blocks or using other accessories.
AKKOtune Bandoneon will be available from January 2025.
October 2024
The top-of-the-line system announced in July is now ready and has already been delivered once. The new system is called AKKOtune compact V5.1 All-In-One (ATcAIO).
The ATcAIO can be ordered at the price of version 4.1 AKKOtune compact USB until the end of 2024.
This tuning table now always contains built-in microphones with a USB output. The Chromatic Tuner has been added, which makes it possible to record individual notes and display their tuning. An extended analysis is possible with a PC program that receives the microphone signals via USB.
Instructions for using the Chromatic Tuner can be found here.
September 2024
The AKKOflip system for bandonion soundboards has been replaced by a newly developed add-on device for AKKOtune DESK. The new AF-Bandonion consists of a box that represents the bellows volume with an attached base frame. The base frame has electromagnets at the 4 corners which can be switched on and off. The soundboard of the bandonion is clamped into the attached turning frame via an adapter ring.
The turning frame is pressed onto a seal on the base frame by the magnets. The volume under the soundboard is thus sealed airtight. The blowing or suction air generated by the AKKOtune compact acts on the mounted reed plates via the volume. The device is optionally available with built-in microphones inside and outside with USB output.
July 2024
The systems in the AKKOtune series are being renewed.
COMPACT: AKKOtune compact is getting a new top-of-the-line system.

d) Connection for remote start pedals
e) Air pressure display
f) Rotary knob for ON/OFF and wind speed
g) Switch for general wind direction reversal
h) Button for short-term stop
i) Button for wind control
j) LEDs for voltage display
k) Fuse for system
l) External 12V power supply
m) Worktop 60 x 38 cm, with leather cover
n) Blowhole slots for quick changes, with locking mechanism
o) Threaded bushings in the worktop for attaching accessories
The new AKKOtune compact All-in-One V5.1 contains everything that the ATc (AKKOtune compact) has and also the option of checking the tuning on the device with a “chromatic tuner”.
On the right of the control area there is a pointer display and LEDs that show whether the tuning is too low, too high or OK. A sound can also be output that can be compared with the blown reed. The technology of a well-known manufacturer was integrated for this.
The ATcAiO V5.1 always has a built-in microphone and an associated gooseneck microphone, which is long enough to extend over the keyboard of a halved accordion and can pick up the tones from the treble. The signal strength of both microphones is adjusted with two controls, and a switch is used to select which microphone signal is used: blowhole, gooseneck or both.
With another switch, the microphone signal can be routed either to the internal chromatic tuner or to the USB port if you are working very precisely with an external tuner such as Dirk's Accordion Tuner.
Connections for external foot pedals can be found on the left side. You can connect a foot switch for wind control (up / down / stop or short stop) and a pedal for external control of the wind strength. There is a switch on the front for selecting "internal / external wind strength".

The AKKOtune BlowBox module is very suitable if you want to replace a bellows in a tuning table that is located underneath. The bellows is replaced by a box that is mounted under the worktop instead of the bellows. The BlowBox module is located in this box and can generate the necessary PUSH or PULL that was previously generated by the bellows. The only difference is that the pressure can now be regulated electronically and there is no limited volume. Here is a schematic presentation as an example.
the other day I got encouraging feedback from two customers:
hello Robert, I just wanted to let you know how impressed I am with the AKKOtune compact. Yesterday I finished building the workbench for the device and was able to use it briefly. I can tell how much thought and consideration you put into perfecting the design.
Hi Robert and thank you so much for all your instructions.... I would like to place an order for additional accessories.... and let me thank you again for such an amazing machine.... I am overwhelmed by your precision and fine craftsmanship.

AKKOtune modular LE now with new BlowBox - see PDF
AKKOtune compact Version 5 is released. New in this version is the ability to control the air pressure with a foot pedal. After activation by a switch, the internal fan is adjusted by the rocker position of the pedal. You can preset the maximum pressure on the pedal so that the air flow can be increased very sensitively, while you can monitor the pressure on the display. You can still choose between versions 4 and 5 when ordering.

BEWARE OF FRAUD!
AKKOtune is a desirable system! This can already be seen from the fact that fraudsters on the Internet are trying to use the name AKKOtune and the image of an old system at a sensationally low price to persuade interested parties to hand over their account details and their money. Since the price of $61.88 can only be a trap that no sensible person should fall for, it follows that the blowers installed in the system already cost more when purchased. Thanks to the customer who pointed it out.

AKKOflip Bandonion AFB
There is now a special version of the AKKOflip for tuning of Bandonion, Chemnitzer Konzertina and other instruments, which have a sound board, on which the reed blocks are fixed together with reedplates.
The problem with these sound bords is,
- the reed blocks are often not removable
- the reedplates carry up to 12 reeds (times two) next to each other
- the reedplates sometimes have different thicknesses (within one plate)
- the permanently mounted keys are on the opposite side
You can only blow the reeds correctly if the reedplates are in their working position, i.e. fixed on the sound board. To do this, the corresponding key on the opposite side of the sound board must be pressed.
Now we have developed a device as an accessory for the tuning table, which makes it possible to clamp the sound board very easily airtight as if it were inserted in the instrument.
We call this device a swivel box (with a swivel frame), where the swivel box forms the resonance chamber for tone development. The sound board is mounted on an adapter plate, which always has the same external dimensions. There are 3 different AFB sizes availabe for adapter rings of 280 x 280 mm (AFB M), 280 x 300 mm (AFB L) and 300 x 320 mm (AFB XL).
Since the sound boards differ from instrument to instrument, the respective adapter plate must be made individually by the tuning craftsman. That means that the adapter plate forms a kind of ring made of approx. 6mm thick plywood, cut out on the inside so far that the reed blocks and plates fit through it.
After the sound board has been screwed onto the adapter ring, it can be clamped into the swivel frame with the keys facing upwards. Now turn on the airflow from the AKKOtune tuning table and press the key of the tone chamber you want to check.
After the swivel frame has been quickly unlocked, it can be lifted and rotated very easily.
To do this, it sits in a holder that guides it and allows the sound board to be fixed at any angle of rotation. This allows the sound board to be placed so that you can access the reedplates and reeds for tuning.

The AKKOflip system gets an addition: AKKOflip for Bandonion. The bandonion and other instruments with similar construction can now be measured and tuned with AKKOflip. The lateral end pieces with the button mechanism and the mounted reed plates can be fixed on the top plate with an adapter. All notes are playable because the buttons are on top when AKKOflip is closed. When opened, the reeds are easily accessible. The new AKKOflip system will soon appear in the AKKOflip price list.
April 2023
For those who want to use their bellows driven tuning station also in future we developed an upgrade that that provides some advantages of the AKKOtune DESK worktop without having the full version with it's increased weight and size.
AKKOtune miniDESK complements the cover plate of a hand-operated tuning bellows with interchangeable blowholes and corresponding accessories, as well as an adjustable guide rail for reed blocks.
You will find the AKKOtune miniDESK with different variants in the price list for Special Accessories.

The Multiholder (code E1) has been replaced by three smaller reedplate holders. The previous E1 was quite complicated to make and expensive. Now the single replacements E1-1, E1-2 and E1-3 certain reed plate widths, that you consider important. The prices are lower and the products is available faster.
You will find the new AKKOtune Multiholders in the new price list for Special Accessories.
March 2023
New price lists are online
In the download section the new price lists are ready. The prices are almost the same as before. Only the USD prices had to be corrected upwards according to the current exchange rates. What is new is that the prices for the systems have been freed from the special accessories and a separate price list has been created for them, because the previous summary in one list was too confusing.
We hope that now there is more clarity.

Feedback from a user for AKKOtune compact: ... I would like to order a 2nd unit of that again. Again the same version...
I must say that I am very satisfied with the device and it makes our work much easier in the range of pre-tuning.
With kind regards
