Form Factor and Physical Design
Number of keys
The ASM Hydrasynth Deluxe 73-Key Synthesizer provides 73 full-size keys. This allows you to play melodies and basslines simultaneously without switching modes. The keyboard includes polyphonic aftertouch and velocity sensitivity for expressive performance. In contrast, the ASM Leviasynth Desktop Synthesizer does not list a key count in its specifications. It is designed as a desktop unit. You will need a separate MIDI controller to play it. If you want an all-in-one instrument with a built-in keyboard, the Hydrasynth Deluxe is the clear choice. The Leviasynth is better if you already have a controller.
Form factor
The ASM Hydrasynth Deluxe 73-Key Synthesizer is a portable keyboard. It measures 52 inches in length, 19.7 inches in width, and 10.6 inches in height. It weighs 43.7 pounds.

It is compact and lightweight. This form factor is ideal for saving desk space. It is not designed for handheld play. You must choose based on whether you need a built-in keyboard or a compact sound module.
Key action
The ASM Hydrasynth Deluxe 73-Key Synthesizer features a velocity-sensitive keyboard with polyphonic aftertouch. This means you can press harder on individual notes to change the sound in real-time. It also supports note-on and note-off velocity. The ASM Leviasynth Desktop Synthesizer does not list key action or aftertouch in its data. As a desktop synthesizer, it likely relies on external controllers for performance data. If you value tactile response and polyphonic expression from the instrument itself, the Hydrasynth Deluxe is superior. The Leviasynth leaves this entirely up to your connected MIDI gear.
User interface
The ASM Leviasynth Desktop Synthesizer includes a multi-color touch screen. This provides an intuitive user interface for navigating patches and settings. It also supports the free ASM Patch Manager for Mac and PC. This software helps with firmware updates and patch management. The ASM Hydrasynth Deluxe 73-Key Synthesizer features a multi-function ribbon controller. This ribbon handles modulation, pitch bend, and theremin mode. It does not list a touch screen in its specifications. If you prefer visual menus and computer management, the Leviasynth is better. If you prefer tactile ribbon control for real-time tweaking, the Hydrasynth is better.
Sound engine features
Both synthesizers offer 16 voices of polyphony. The ASM Hydrasynth Deluxe 73-Key Synthesizer uses digital wave morphing. It supports single, multi, dual, and keysplit voicing options. It also supports microtuning via MIDI Tuning Standard files. The ASM Leviasynth Desktop Synthesizer offers eight oscillators per voice.
