A versatile virtual analog polyphonic synthesizer with a motion sequencer, MPE support, and a large preset library, offering intuitive sound design for a wide range of musical styles.

Core Synthesis and Interface
The Alpha Synthesizer is a virtual analog polyphonic stereo instrument inspired by classic analog synths but enhanced with a modern, musical approach. Its interface is designed to guide you naturally, with panels arranged to follow the audio signal flow from left to right, making it easy to tweak each component and design your own sounds. Visual filters, sliders, LFOs, and envelopes help you see exactly how your sound is shaped, speeding up the learning process.
Thanks to its low CPU usage, you can run multiple instances without worrying about performance, which is ideal for complex arrangements. The synth also includes a unique motion sequencer inspired by modular synthesizers, adding rhythmic and expressive modulation to pads, leads, and sequences. It can be coupled with the built-in arpeggiator, and its MPE compatibility allows for greater expressivity when used with compatible controllers.
Sound and Effects Engine
The Alpha offers a wide sonic range through its stereo oscillators and multiple modulation targets, allowing you to craft anything from lush pads to sharp leads and deep basses. Five built-in effects provide additional shaping options without needing external processors, while the extensive factory presets and templates serve as a solid starting point for your own sound design explorations.
Whether you are looking for classic analog warmth or contemporary digital textures, the combination of oscillators, filters, and modulation tools gives you the flexibility to create a vast array of timbres. The motion sequencer adds an extra layer of movement, making static sounds come alive and enabling complex rhythmic patterns that evolve over time.
Preset Library and Inspiration
Included with the Alpha are several preset packs designed by various artists, each bringing a unique flavor. The Sound Test Room offers a wide variety of patches, from vintage-style keyboards to cinematic arps and lo-fi sounds. Red Sky Lullaby contributes expressive presets reflecting a background in sound design and iOS music production, while Yawdel’s pack focuses on Future Bass and Trap, with massive basses and gritty synth textures.
The Hoops Collection, curated by the BLEASS team, showcases the synth’s features, including MPE and the arpeggiator. Lily Jordy’s presets blend organic electronic elements, and The GarageBand Guide pack explores sci-fi inspired sounds with leads, pads, and glitchy effects. Torley’s jumbo pack delivers intense, expressive patches, and Sound Of Izrael offers soft pads and bright leads. A dedicated MPE preset pack unlocks the full potential of expressive controllers, and a Funk pack provides melodic basses and rhythmic synth riffs.
Workflow and Practical Use
In a production workflow, you can start by selecting a preset that matches your desired mood, then tweak the filters and envelopes to shape the sound further. The motion sequencer is perfect for adding rhythmic interest to sustained chords or creating evolving sequences that respond to your playing. Using the arpeggiator in conjunction with the sequencer can generate complex patterns quickly, inspiring new musical ideas.
For live performances, the MPE compatibility allows for expressive pitch bends and pressure changes, making the synth feel more like an acoustic instrument. The low CPU usage means you can layer multiple instances for rich textures without sacrificing stability. The presets provide a broad palette, from vintage analog emulations to modern electronic sounds, useful in genres like pop, electronic, film scoring, and anything requiring unique synthetic textures.
