Our products are a recreation of real instruments, as much as possible and as much as technology allows. They are used as a simulation, or replacement, of the sound of acoustic instruments for both studio production and even live performances. They are made as soundware for Native Instrument Kontakt and cannot work independently as VST or AU instruments. Only you can use them and you must not give them to others because each of the products has an advanced watermark that identifies you as a customer and user, so you can be prosecuted.
They can also be used for educational purposes, and in case you are a lecturer, feel free to contact us because we have special graphic solutions, as well as discounts, for you. The best example of this is www.accordiononlineacademy.com

The only difference between the models is in the sound, that is, the tone timbre. Each instrument has its own distinctive tone. If you do not understand specific models, then we advise you to listen to demos.

As the specifications say, you need a not overly demanding PC or MAC with a low latency audio interface, a full version of Native Instruments Kontakt 6.2.2 or newer installed, and a control instrument. Our instruments are not libraries and you open them with the File - Load... option or by dragging a .nki files into an empty interface area. It is also desirable that the control instrument has an expression or breath option to exploit the full potential of the accordions.

Immediately after a successful purchase via the email address you provided during the purchase, you will receive a link from which you can download the purchased product. For security reasons, the link is for three downloads and is valid for 7 days.

No. There are only electronic delivery option. Boxes on product presentations are just a graphic design.

Of course. All you have to do is to send an inquiry message to the email address info@virtual-acoustic.com and an Order ID or email address used during the purchase as well as the purchased product (if there were more than one), and we will find you in the records and generate new download link(s) for you.

As pointed out in the “Refund policy" this is not possible.
Our products are basically audio samples so there is no return or deactivation. Once you get them, they stay yours forever. Anything other than this is considered an attempt at illegal appropriation, or abuse. Before being released, our products were thoroughly tested on many different types of computers.
Whether you say so:
- you did not receive the link
- the link does not work
- the wrong file is in the link
- file does not work
- Kontakt does not open the product,
or anything else, we know that may not be true. We know what we made, present, sell and send, and if you follow all the instructions and meet all the technical requirements, everything must work as it works for everyone. Why would it be in our interest to deceive anyone? However, if you really are not able to get the purchased samples to work, we guarantee that we will provide you with all the support to make it work, in the end be prepared for the TeamViewer connection as well.

Our products are not software but samples and cannot have a time limit or be deactivated. This only means that you are not using the full version of Kontakt, but a free Kontakt Player that is not supported, which is emphasized in several places on our site. If you see the software name "Kontakt Player" istead of “Kontakt” in the upper left corner, it means it's a problem.

The Kontakt format is made and intended exclusively for NI Kontakt sample player. It contains a user interface with all the controls and maximum capabilities provided for a virtual instrument.
On the other hand, the sf2 format is a classic convertible format ready for manipulation. It can be converted to any other sample format, edited and used in all sample players, both software and hardware. It does not contain a user interface (ie depends on the player), there is no variation of tones, noises, effects or any benefits that favor a more realistic sound, the samples are 16-bit compared to Kontakt where they are 24-bit, require additional level settings of each of the basic voices depending on the player, etc. .

Although seemingly similar, these models differ in many ways. Primarily an engine and a way of sound synthesis, that is similar to "rompler" synthesis, in new models and has practically 128 x 128 sound variations, while in older models there are only 4. New models have a natural sound morphing depending on the volume of the bellows (expression) while at the old models expression only changes the volume. The sound of the VA2G model has been processed so that it is much easier to fit into the mix. Also the recording technique as well as the equipment used in the new models is much better.You can notice other differences both in the demos and in the descriptions.

We really cannot know how loading samples into your hardware or software sampler/sample player/keyboard works because we have no contact with the all possible devices/software. Our sf2 samples are classic SoundFont samples and should work on any hardware or software sampler/sample player that reads that format. Please read the user manual for your device or convert the samples to another format more suitable for your instrument, if possible. You also need to know that additional adjustment of all sounds in each sample player is necessary, especially in order to make the sound of the samples as convincing and as close to reality as possible.

We do not keep projects because in most cases they are not even done in the our studio.

Many say the real instrument is inviolable. And we agree with that to some extent. But you also need to be realistic and look at all sides. The real instrument, in this case the accordion, has more shortcomings than our samples, especially the new models (VA2G) such as: broken reeds, mechanism, or bellows, detuned tones, the weight of the real accordion, the inability to completely avoid the key noises if need, inability to change and edit already recorded audio signal, complete recording equipment, lifespan, price ratio of real and sampled instrument and so on.

You cannot use our samples as libraries but only as instruments. You load them in the Kontakt by option File - Load ... and choose the .nki file or by dragging the same file to the right part of the Kontakt interface which is intended for instrument graphinc interface.

To get started, check the settings of the Kontakt itself. Make sure your control instrument is connected and the appropriate MIDI channel is selected. Check both the sound card and the position / value of the expression pedal or MIDI CC11 value. Ultimately try to load any other samples to make sure it works. In the bass version, at first set both MIDI channels to match with the control instrument.

The bass version of the accordion sample is only the left side of the accordion (bass), unlike other models of VA2G accordions which are the right side (treble) tones. It is designed to work as well as a real accordion and you can control separately bass tones from bass chords with different MIDI channels or the same MIDI channel but in different octaves. Also the tones start from the first octave, the chords from the third and the registers from the fifth octave. There is more details in the user manual.

Of course. For a start, we were based on accordions because it is certainly an area we know best, but we plan to sample some other instruments, mostly that are rare or, in our opinion, not well made. We can't say in advance what we are going to do because it depends on many factors, the main one being the availability of a good sounding instrument for sampling. We mostly promise that there will be more samples in the future and especially accordions.

We use 2Checkout services for online sales. Their service includes the option of electronic delivery of the purchased products in the form of a download link sent to the email address you entered during the purchase. The first thing we can recommend is to check the email including the "junk" folder. If the email really didn't arrive, check to see if the payment was successful. If it is then contact 2Checkout support or us. The problem will have to be solved as soon as possible.

During the process of making of real accordions, piano and button versions of the same accordion models are usually made. This means that there is no difference except in the mechanism of making the sound (keys or buttons) and two tones more in the lower part of the button versions. In our samples, especially in the VA2G models, the difference is also in the visual part, including the change of colors of the buttons and their background as well as the system (B or C) but also change of the number of rows (from 3 to 6) of each system.

You can buy our products exclusively on our website! We do not cooperate with anyone and if anyone offers to sell our products under the pretext of being a reseller, know that this is not true.

If this happens, it just means that the folder structure is broken or certain files are missing. The easiest way to solve this is to recompress the file you received after the purchase in an empty folder without subsequently disrupting the folder structure.

First, make sure the MIDI controller sends a classic (monophonic) aftertouch. Polyphonic aftertouch will not work.

If that criterion is met then there is definitely a problem in the aftertouch information that your MIDI controller sends. Also try adjusting the aftertouch envelope if that option exists in the settings. Our products have been tested on multiple MIDI controllers with the correct aftertouch and they work perfectly on each.

Product prices are as they are. Prices were influenced by many factors that we know best.

Each of the VA2G models is sold separately and there are no product combinations at a discount. At least for now.

Unfortunately, the technology of making VA2G models does not allow any other format than NI Kontakt. Their sound would not be as it is nor would it be the same as the capabilities these models have, so there are no other formats other than NI Kontakt. Also, do not ask us to make you anything other than the formats already offered on the site because we will not do so.

From now on, we make the names of the sampled instruments by personal choice, reminiscent of some of the original ones that were sampled as well as to the country of their origin. We do this both to create our own brand and to avoid infringing on the copyrights of their real owners. You can find the exact, or as close as possible, models of the sampled instruments on the page of the desired instrument in the "Specifications" section.

Unfortunately, this option does not exist with us, so before buying, please think carefully about what you are buying. Once again, we recommend that you read all the descriptions and user manuals, listen to all the demos and watch all the videos and images before you decide to buy. Only in this way both you and we can avoid embarrassment.
