Frequently Asked Questions
DC-coupling allows continuous voltage levels, essential for smooth and dynamic CV modulation, unlike AC-coupled interfaces which can attenuate or distort signals.
Latency is exceptionally low, making it suitable for live performance and real-time processing; it's one of the ES-9’s biggest strengths.
No, the ES-9 requires a more modern operating system – Windows 7 or later, macOS, or iOS – due to driver requirements.
