Spark AR Studio is only available for Mac OS 10.12. If your computer is not compatible and you would like to learn more about our product announcements and beta testing opportunities, join our mailing list. Spark AR Studio Mac OS 10.12. Spark is an Open Source, cross-platform IM client optimized for businesses and organizations. It features built-in support for group chat, telephony integration, and strong security. It also offers a great end-user experience with features like in-line spell checking, group chat room bookmarks, and tabbed conversations. Combined with the Openfire server, Spark is the easiest and best alternative to using un-secure public IM networks.

On Mac OS you may have to allow the app to run via the the mac OS Security setting, because the app has been downloaded from the internet. Using other Pedals with the Amp.
