Two synthesizers announced earlier this year have major updates to share. First up, Applied Acoustic Systems (AAS) Strum GS‐2 now includes electric guitars in addition to acoustic. Strum GS‐2 uses modeling to reproduce the various parts of the guitar chain–strings, bridge, soundboard, pickups, amplifier, and speaker cabinet. As a result, it’s able to create very impressive guitar tracks while sparing your hard drive from gigabytes of sample data. Current users, grab version 2.10 now. Don’t own it yet? The $199 price has been discounted to $149 again until June 30.

Waldorf Nave is out for the Mac! Waldorf’s first iOS synthesizer app, created by chief engineer and 
director Stefan Stenzel, NLog mastermind Rolf Wöhrmann and design guru Axel Hartmann, can now be instantiated in your favorite AU, VST or RTAS compatible DAW for $199. It requires OS X 10.7 or later. Jumping the other direction, Waldorf’s desktop drum synth Attack is now available on iPad for $14.99. It requires iOS 7 or later, and an iPad 3 (retina), iPad mini (1, 2, or 3), or iPad Air (1 or 2).
