Subject: Formal clarification request — KeyLab mk3, “full custom” marketing and absence of per-mode MIDI channel
Hello,
I am posting this as a formal clarification request on the record.
To avoid any confusion: I first purchased a KeyLab Essential mk3. I then purchased a KeyLab mk3 specifically because it was marketed as “full custom” , and I expected that this level of customisation would include, on the keyboard itself, the ability to assign a MIDI channel per mode . That is the reason for my purchase.
In actual use, the KeyLab mk3 does not provide a MIDI channel per mode on the keyboard. This is not a subjective preference or a minor convenience. It is a functional limitation that directly affects the ability to control different MIDI destinations according to the selected mode. For users who rely on per-mode MIDI channel assignment, this is an essential feature.
I am therefore challenging the gap between the product presentation and the actual functionality. The expression “full custom” is an allegation concerning the essential characteristics of the product and its fitness for the intended use. If the KeyLab mk3 does not allow a MIDI channel to be assigned per mode on the keyboard, then that limitation must be stated explicitly, visibly and unambiguously. It cannot be left to consumers to discover after purchase.
For reference, the relevant provisions of the French Code of Consumer Law are as follows:
Article L217-3 of the French Code of Consumer Law
“The seller delivers goods that conform to the contract and to the criteria set out in Article L. 217-5. The seller is liable for defects of conformity existing at the time of delivery […] which appear within a period of two years from delivery.”
Article L217-4 of the French Code of Consumer Law
“The goods conform to the contract if they meet, where applicable, the following criteria:
1° they correspond to the description, type, quantity and quality, including in particular as regards functionality , compatibility, interoperability, or any other characteristic provided for in the contract;
2° they are fit for any special use sought by the consumer, made known to the seller no later than at the time of conclusion of the contract and accepted by the seller […]”
Article L217-7 of the French Code of Consumer Law
“Defects of conformity which appear within a period of twenty-four months from delivery […] are, unless proven otherwise, presumed to have existed at the time of delivery […]”
Article L121-2 of the French Code of Consumer Law
“A commercial practice is misleading if it is committed in one of the following circumstances: […]
2° where it is based on false allegations, indications or presentations, or presentations likely to mislead, and concerns one or more of the following elements: […]
b) the essential characteristics of the goods or service, namely: their substantial qualities […] their fitness for purpose […]”
Subject to the court’s assessment, the consequences are as follows:
- The product must correspond to its description, including in terms of functionality .
- The “full custom” claim cannot be used to suggest a level of customisation that the product does not actually provide.
- The absence of per-mode MIDI channel on the KeyLab mk3 keyboard is a serious conformity issue with regard to the expected use and the product communication.
- For 24 months, it is for the professional seller to prove that the defect did not exist at the time of delivery, not for the consumer to prove the opposite.
I therefore request that Arturia answer publicly and clearly the following questions:
- Does the “full custom” claim include, yes or no, the ability to define a MIDI channel per mode on the KeyLab mk3 keyboard?
- If not, why is this limitation not stated explicitly, visibly and unambiguously in the essential product specifications?
- Does Arturia acknowledge that the absence of per-mode MIDI channel may make the product unfit for the use sought by certain users?
- Is a firmware correction planned? If so, within what timeframe and with what written commitment?
- If not, what conformity solution does Arturia offer to affected purchasers?
I am not asking for a vague answer such as “the product works as designed”. I am asking for a factual, precise and on-the-record position on the presence or absence of the per-mode MIDI channel function on the KeyLab mk3, and on the exact scope of the "full custom”claim.
I retain all purchase evidence, product pages, marketing materials and correspondence. This message constitutes a formal request for clarification and, where applicable, a formal notice to bring the product into conformity. I reserve all rights under the French legal warranty of conformity and the rules on misleading commercial practices, in particular against the professional seller.
I await a written and reasoned response.
