Jack Hertz Report post Posted October 8, 2016 Kastle is a mini modular synthesizer with headphone output, 2 in/out ports for interfacing other gear and it runs on just 3 AA batteries. It is DIY friendly and ideal for beginners in modular synthesis, but it will add quite some unique functionality to any modular synthesizer systems. It delivers the fun of modular synthesis at cost and fits into your pocket so you can play it everywhere! View full synthesizer Share this post Link to post Share on other sites
