Arpecyza!1 is a dynamic 16-step arpeggiator synthesizer designed to inspire creativity. It features dual single oscillator synth engines, each equipped with HADSR envelopes and 24db low-pass filters, delivering rich and expressive sounds. The built-in 16-note host-synced arpeggiator includes a note slide function, allowing smooth melodic transitions and rhythmic complexity.

Beyond its core synthesis and arpeggiation, Arpecyza!1 offers six patchable host-synced parameter sequencers and three patchable host-synced LFOs, providing extensive modulation possibilities for evolving textures and dynamic soundscapes. Additional controls like MIDI note message transposition and shuffle add rhythmic variation and performance flexibility.

The integrated stereo wave recorder enhances workflow with auto start/stop functionality, peak meters, and manual controls for recording level, balance, and BPM override. Partial automation and user-assignable automation capabilities allow precise control over parameters, making Arpecyza!1 a powerful tool for both live performance and studio production.
