This article applies to purchases of digital sheet music in the Sostenutoo store. For these purchases it supplements the preceding articles and, where they differ, it prevails.
12.1. Sale.
The Seller sells sheet music in its own name, on behalf of the music publishers who entrust it with their works (hereinafter "the Publisher"). The purchase is made by a manager of the ensemble (owner or administrator of the ensemble on the platform), on behalf of that ensemble (hereinafter "the Ensemble"). Each work purchased (hereinafter "the Work") is delivered as PDF files, full score and separate parts (hereinafter "the Copies").
12.2. Price.
The price of a Work is set excluding VAT. It is the same whatever the Ensemble's country. The VAT due according to the billing address is added to it, under the conditions of article 4. The Work's page shows the price excluding VAT and the price including VAT for France; the exact amount to be paid is displayed before payment is confirmed.
12.3. Delivery and right of withdrawal.
The Copies are placed in the Ensemble's repertoire as soon as payment is received. They are digital content supplied without a physical medium: under article L221-28, 13° of the French Consumer Code, the right of withdrawal cannot be exercised once supply has begun with the purchaser's prior express consent and express waiver of this right. This consent and this waiver are collected before each payment, by means of a checkbox.
12.4. Licence granted to the Ensemble.
The purchase gives the Ensemble a licence to use the Copies (hereinafter "the Licence"), on the following terms. They are presented and accepted before each order.
12.5. Marking of the Copies.
Each page of the Copies bears, in its bottom margin and without hiding the musical text, the notice "Exemplaire sous licence nominative" (copy under personal licence), the name of the Ensemble, the order number and date, and the Publisher's rights notice. On narrow pages, particularly in the so-called "march" format, this notice is abbreviated and keeps at least the order number; it appears in full in the file's metadata. The marking identifies the Ensemble, never its musicians.
12.6. Refunds and withdrawal of access.
Given the immediate delivery, an order is refunded only for a legitimate reason: an error reported to the Seller before any download, a technical defect in the Copies that the Seller cannot remedy, or a legal obligation. Requests are made to support@sostenutoo.com, quoting the order number.
When an order is refunded, or its payment is cancelled, in particular following a chargeback, the Licence ends and access to the Copies of that order is removed from the platform. The Ensemble then stops using any Copies it may have kept.
12.7. Information passed on to the Publisher.
For each sale, the Seller gives the Publisher the order number and date and the name and country of the Ensemble. In the event of unauthorised distribution of a Copy, and at the Publisher's reasoned request, it may also give the Ensemble's address, the name and email address of the person who placed the order, and the dates on which the Copies were downloaded. Payment data and the data of the Ensemble's musicians are never passed on. Details are given in the Privacy Policy.
