User Reviews and Opinions

Overall, the M-VAVE SMK-37 Pro is praised for offering a feature-rich package at a budget-friendly price point. 

• Pros: Users appreciate the extensive feature set, including the built-in synth and wireless connectivity, which offers more functions than many controllers from major brands. The pads are described as soft and responsive with aftertouch. The inclusion of a clear display is also a positive for visual feedback. Active firmware updates from M-VAVE are seen as a good sign of support.
• Cons: Some users have reported minor issues, such as occasional audio clicks or pops from the internal synth, which may be related to buffer overruns. There can also be some latency issues for real-time live performance, and the feel of the keys may not be professional grade. The physical faders can have a slight wobble.
