Frequently Asked Questions
Optical tracking is generally cleaner and less prone to string noise than magnetic systems, but it can be more sensitive to lighting conditions and other electronic interference.
While it's designed for 4-, 5-, and 6-string basses, string spacing and pickup height need to be carefully adjusted for optimal results; very unconventional basses may require modifications.
A versatile synth module with a wide range of sounds – like a Roland Juno or similar – will give you the most flexibility and allow you to explore a broad range of sonic textures.
