Frequently Asked Questions

Can I charge my iPhone/iPad while I'm using it? Yes, with the optional iRig PSU 3A connected to the DC port.
Does the 25-key model have pads and encoders like the 49-key model? Yes, it includes 8 RGB pads (in a 2x4 layout) and 5 touch encoders in total (4 knobs + 1 data/volume encoder).
Do I need drivers? It's class-compliant on macOS/iOS. On Windows, the IK ASIO driver is recommended for low latency.
