Thank you for your interest in Sonoma Wire Works products. We appreciate all of our customers and the past and present Sonoma team. We've enjoyed creating products that so many musicians found to be helpful. After much consideration and for many reasons, we are announcing:
1. On July 31, 2022, RiffWorks, DrumCore 4, and iOS apps will no longer be sold to end-users by Sonoma.
2. On October 31, 2022, Sonoma will no longer offer product support.
While we are looking for a new home for RiffWorks and DrumCore, and have found some potential interest, there is no available information or guarantees for the future of these products.
July 31, 2022: Sonoma will no longer sell new licenses of RiffWorks, DC4, or DC4 updates from DC3/DC2/KC. The following may be available for purchase and download until servers are turned off at the end of October: DC4 Crossgrades, DC4 add-on sales of GrooveSets and Drums Kits, and RiffWorks InstantDrummers.
Important: As of July 31st, downloads may not be possible if the servers are overloaded by users attempting to download and back up content.
No refunds will be offered, so if you purchase any add-on content, you do so at your own risk.
August 31, 2022: No further redemptions of newsletter offers and contest prize giveaways. No DC3, DC2.5 and KitCore support or registration assistance.
October 31, 2022: Sonoma will no longer support any products, including RiffWorks, DrumCore, and iOS products. Sonoma’s services, website, online guides, online store, support, and email addresses will no longer be available. Software and add-on drums (DrumCore GrooveSets/Drum Kits and RiffWorks InstantDrummers) purchased in Sonoma’s online store and in DC4 will no longer be available to download.
Customers may try to continue using RiffWorks Standard, DrumCore 4, and add-on content after October 31 by following the tips below. However, there are no guarantees.
Add-on content (including DC4 crossgrades, DC4 GrooveSets/Drum Kits, and RiffWorks InstantDrummers) purchased before and between July 31 and October 31, 2022, are non-refundable. Sonoma cannot guarantee that any add-on content will be downloadable, as Sonoma’s servers may be overloaded with customers attempting to download previously purchased content. We encouraged/warned customers (through newsletters, the website, social media, and support emails) to keep backups of software and drums on their own drives. Therefore, if you have trouble downloading previously purchased content, please look for your backups on your own SSD drives. All DC4 and RW software licenses and add-on drum purchases are non-refundable.
Tips for Attempting to Continue to Use RiffWorks and DC4 after October 31st:
RW and DC4 may continue to work for you on your current computer configuration with some limitations listed below, but there are no guarantees. It is recommended that you keep disk image backups of your current computer system, software, content, preferences, profile file, etc., in case you would like to attempt to install the software on a different/similar computer (with the same configuration) in the future. We recommend that you keep this disk image on at least 3 (THREE) separate backup drives.
There are no guarantees this will work now or in the future.
