KASTLE DRUM

The Kastle Drum is a mini modular synthesizer with a headphone output, 2 in/out ports for interfacing other gear, and it runs on just 3 AA batteries. It is ideal for beginners in modular synthesis, but it will add some quite unique functionality to any modular synthesizer system. It delivers the fun of modular synthesis at a low price and fits into your pocket so you can play it anywhere!

Kastle is an open source project with all resources obtainable from GitHub. Given that anyone can do anything with the code, we cannot provide any support for user upgrades from Kastle v1.5. All information is easy to find online for curious users, but please understand that we do not have the capacity to help you with that process.
