musicradar.com

The 2hp Vowel module delivers an intriguing palette of vocal synthesis, packed into a compact design. With just a couple of controls, musicians can explore a wide variety of tones, making it a versatile addition to any setup. Its ability to respond dynamically to audio rate modulation is a standout feature, enhancing its functionality as both an oscillator and a modulation source. However, the controls can be tricky to manipulate, especially in tight spaces, which may frustrate some users. While it may not be a must-have for everyone, the Vowel certainly brings unique sonic possibilities to the table that can elevate your sound.
