Setting Up MIDI Input

How to make sure Synfire receives MIDI input from your external keyboard or remote software.

  1. Open Playback > Audio/MIDI Setup and visit the Inputs page.

  2. Find the port of your MIDI keyboard or external interface.

  3. Check the Input box for it.

  4. Play notes on the keyboard. The MIDI icon on the window toolbar should flash.

  5. Also verify the other Input Preferences match your current preference.

Trouble: You may need to do Playback > Reset Audio/MIDI System to make recently connected MIDI equipment appear in the list.
Trouble: On Microsoft Windows, problems may occur if multiple programs attempt to use the same USB MIDI driver at the same time. Especially prone to this are cheap drivers that often accompany inexpensive MIDI hardware. If you wonder why Synfire is unable to receive data from your hardware, there is probably another program already using the USB driver. In order for Synfire and other software to receive MIDI at the same time, you may need to use separate USB interfaces, or look for a more capable driver, if possible. Since this is a frequent problem, you should visit the user forum for the latest solutions (
Trouble: On Microsoft Windows, you may experience problems when multiple programs attempt to access the same ASIO driver. In order to be able to run the engines and a DAW in parallel, you might need to assign them to different audio output drivers. For example, you may want to use the ASIO driver for your DAW and the Windows Audio or DirectX drivers for the engines. On the Mac, running multiple Engines and DAWs at the same time is not a problem.
