We are stoked to introduce the Kastle 2 Alchemist – a patchable, hybrid-synthesis
instrument that empowers you to explore melodies and even harmonic textures, despite
being monophonic.
The Alchemist offers a range of Bastl-brewed Synth Modes – Filter, FM, Supersaw,
Hypersine, and GlitchNoise – which can be combined with its internal effects and the
versatile Pattern Generator. Rhythms and scales are fully customizable via the web-based
app, and expanded MIDI USB compatibility adds even more flexibility.
The Kastle 2 Alchemist is the third firmware release for the Kastle 2 hardware platform,
joining the FX Wizard multi-effects processor and the Wave Bard stereo sample player. The
firmware is fully cross-compatible across all devices in the Kastle 2 Series – meaning the
Alchemist firmware can be loaded onto previous Kastle 2 units and Citadel modules, and
vice versa.
The Kastle 2 Alchemist is the spiritual successor to the original and widely popular Kastle
Synth, introduced in the fall of 2016 and later updated to Kastle 1.5 in late 2017. It also
inherits the DNA of the Kastle Arp from 2023, resulting in expanded musicality.
The Kastle 2 Series is often described as experimental and funky — and while the Alchemist
certainly carries that spirit, this third medieval-themed instrument pushes the platform further.
With carefully crafted synth modes and intuitive controls, the Alchemist expands the musical
range, making it valuable in both beginner setups and complex studio environments.
The Kastle 2 Alchemist is available now for 160 € ex. VAT
