ASM Hydrasynth vs Leviasynth Specs
Number of keys
The ASM Hydrasynth 49-Key Synthesizer provides 49 keys, offering a compact yet playable range for live performance or studio composition. This allows you to access a broader keyboard layout without requiring a full-sized instrument. In contrast, the ASM Leviasynth Desktop Synthesizer does not list a key count in its specifications. It is designed as a desktop unit, meaning it lacks an integrated keyboard entirely. You will need to pair it with an external MIDI controller to play it. If you want a self-contained playing experience, the Hydrasynth is the clear choice. The Leviasynth requires additional hardware for input.
Key action
The Hydrasynth features a proprietary Polytouch keybed that offers polyphonic aftertouch over each note. This allows for expressive control per key, enhancing performance dynamics. The Leviasynth does not specify any key action in its data, as it is a desktop synthesizer without built-in keys. It relies on external controllers for input. Therefore, the Hydrasynth provides immediate tactile expression through its advanced keybed. The Leviasynth shifts the responsibility for key feel and aftertouch to whatever MIDI controller you connect to it. For integrated expression, the Hydrasynth holds the advantage.
Form factor
The Hydrasynth measures 22 x 38 x 9 inches and weighs 32.4 pounds. It is a substantial keyboard unit designed to sit on a stand or desk. The Leviasynth is significantly smaller, weighing only 1.47 pounds. It is a desktop synthesizer, making it highly portable and easy to fit into tight spaces. The Leviasynth wins on portability and space efficiency. The Hydrasynth requires more physical footprint and is heavier to transport. If you need a lightweight, compact solution that does not dominate your workspace, the Leviasynth is the practical option.
Oscillator configuration
The Leviasynth boasts 16 voices with 8 oscillators per voice. It supports complex oscillator configurations including Phase Modulation, Frequency Modulation, Pulse Width Modulation, HTE Sync, and three types of Phase Distortion. The Hydrasynth utilizes an advanced wavetable synthesis engine with 3 oscillators, dual Wave Mutators, and 2 filters. While the Hydrasynth offers flexible filter routing, the Leviasynth provides a higher oscillator count per voice and diverse modulation types. This gives the Leviasynth an edge in raw oscillator complexity and sound design depth for users who need extensive modulation options.
User interface
The Hydrasynth features a user interface designed for quick patch editing with minimal paging and workflow shortcuts. It includes a 4-octave ribbon controller and ergonomic pitch and mod wheels. The Leviasynth includes a multi-color touch screen and an intuitive user interface. It also supports the free ASM Patch Manager for Mac and PC for firmware updates and patch management. The Leviasynth offers modern digital management via software and a touch screen. The Hydrasynth offers tactile hardware controls like the ribbon and wheels. The Leviasynth has the edge for users who prefer screen-based navigation and software management.
