$0/moFreeHiddenPatron count not public
$2/moOuverture patronHiddenOuverture patrons get access to bach prereleases, and their name appears in the list of donors.
Patrons also get a key to remove bach splash screen for a full solar year (splash screen will appear from version 0.8.1).
$4/moWell-tempered patronHiddenWell-tempered patrons can submit feature requests and have exclusive access to video tutorials. This is in addition to the benefits of Ouverture patrons.
A small number of videos introducing easy topics will be accessible to everyone; Well-tempered patrons will also be able to access a larger, and more advanced, set of video tutorials covering specific aspects of patching in bach, and making computer-aided composition in Max.
(We think that these videos may prove useful to get accustomed to the bach environment, and hence it would be a pity if they would not be eventually available for a larger public. However, we promise to Well-tempered patrons that they will be the only ones able to access them for at least for 1 year from their publication date).
$8/moBrandenburg patronHiddenIn addition to all the benefits of Well-tempered patrons, Brandenburg patrons can suggest topics for new videos tutorials and will have their name listed both in the bach website and in the bach overview as "top supporter" (if kept for at least one year)
$16/moGoldberg patronHiddenIn addition to all the benefits of Brandenburg patrons, Goldberg patrons are entitled to 1 hour of private Q&A in Skype/Google Hangouts with one of the bachproject developers per year (if kept for at least one year).
$128/moFriedrich der Große patronHiddenThis tier is designed for institutions willing to support bach. The name of the institution will appear in the welcome message, posted in the Max window at startup (if the tier is kept for at least one year).
Friedrich der Große patrons also have access to the current splash screen-free version of bach, which they can use for GPL-licensed projects. In addition, splash screen removal codes, video links, and other Patron-only content can be made available to students and researchers of the institution. Other specific needs can be discussed privately.
