In the May issue of Soundbytesmag.net I review two very neat new synthesizers, one for the iPad and one for computers. The iPad machine is Shoom, by Yuri Turov, and it's a very nice tri-timbral, multi-polyphonic, microtonally enabled synthesizer with a very nice performance interface. The computer synth is called Virta, and it's by Randy Jones, of Madrona Labs in Seattle. This is a synth that's designed to analyze sounds from the "real world" and extract control information from them and (microtonally) control a very nice collection of modules. Both are inexpensive, both are well thought out, and both are brimming with compositional potential. So check out the reviews here:
