Bastl Instruments Alchemist Kastle 2

he Alchemist has a carefully tuned wide timbral range spanning across 5 synthesis modes (FILTER, FM, HYPERSINE, SUPERSAW and GLITCHNOISE) accessed by main TIMBRE sweep that is refined by the RATIO control.

• The ENV macro knob affects different parts of the synth and sequencing engine to maximize musicality and it even lets you continually morph between the synthesis modes and access truly unique sounds.
• The timbral palette is further extended by the dual FX section which offers either a wide delay that will smear the arpeggios into echoed harmonies or a chorus-flanger-distortion-combfilter macro custom tuned for each synth mode.
• You can also access gliding rubber textures with the PITCH SLIDE macro that applies pitch envelope and portamento.

The Kastle 2 Alchemist is a compact, portable instrument that runs on 3‌‌‌‌‌‌‌ AA batteries or USB-C, so it can inspire you anywhere, anytime. It loves to jam with your other portable gear—sync it with the sync in/out ports, and use the audio input to mix external signals with the Alchemist’s output or run them through its built-in effects. 

All main parameters can be modulated and tightly sequenced by the surprisingly powerful CV and GATE pattern generator alongside with syncable LFO that can be modulated as well. 

The Alchemist is a semi-autonomous companion that keeps surprising you with fresh ideas. Kastle 2 is not just a sound box—it’s a powerful MIDI controller and sequencer. Send finely curated USB MIDI data to your DAW or USB MIDI instrument, and discover new ways of playing and interacting through a modular interface. The Alchemist both sends and receives USB MIDI, making studio integration a breeze!
