Explore hybrid synthesis, evolving patterns, and hands-on sound design with a compact, patchable instrument built for experimentation.
The KASTLE 2 ALCHEMIST combines four oscillators with FM, waveform mixing, ring modulation, and stereo sound shaping. Its patchable modulation system and tempo-synced pattern generator invite you to discover new sounds through connections and happy accidents, while USB MIDI and analog sync make it easy to bring other instruments into the session.
Key Features
Hybrid Sound Creation
- Four oscillators with FM and feedback for rich, evolving tones
- Raw waveform mixing, ring modulation, and track-and-hold processing for experimental textures
- Stereo noise with track and hold, a stereo filter, and a transient shaper for further sound sculpting
- PITCH control spans ±3 octaves from the base note
Patchable Modulation and Patterns
- Built-in LFO with triangle and pulse outputs, reset input, and attenuverting modulation
- Choose synced or free-running LFO operation
- Tempo-synced, patch-programmable pattern generator with GATE and CV outputs
- Set the number of sequencer steps through the web-based app
USB MIDI and Sync
- USB MIDI input supports clock, notes, control changes, and pitch bend
- USB MIDI output lets Alchemist work as a MIDI controller or sequencer, sending clock, notes, and control changes
- Analog sync input and output for connecting with other portable instruments
- Modular I/O connections via the right channel of the sync jacks
Stereo Connectivity
- Stereo audio input with adjustable gain up to +12 dB
- Stereo output capable of driving headphones up to 250 ohms
- Stereo audio processing at 44 kHz/16-bit
Perfect For
