MIDI Connectivity

The S-4 supports MIDI communication through both its dedicated MIDI In/Out ports and the USB-C connection. Each of the four tracks can be independently controlled via dedicated MIDI channels. The MIDI In and Out ports use TRS Type A 3.5mm jacks and require a compatible adapter to connect to standard MIDI DIN cables.

5 Pin DIN MIDI In / Out

The rear panel of the S-4 includes two dedicated MIDI ports designed for use with 3.5mm to 5-pin DIN Type A adapters. These allow standard 5-pin DIN MIDI cables to be connected seamlessly. To control the S-4 using external gear—such as a MIDI keyboard or sequencer—simply connect the device to the MIDI Input port.

If the device connecting to S-4 also uses a MIDI TRS Type A connection, a standard 3.5mm stereo jack to jack cable can be used instead of the adapters both ends.

USB MIDI In / Out

The USB-C Connection also allows interfacing to other gear, DAWs and controllers. S-4 is supported as a USB MIDI device on Windows, macOS, and Linux.

Ensure the USB cable is specified for data communication.

Set the S-4 and the external device to the same MIDI Channel i.e. Channel 1.

USB Host/Device mode

The S-4 USB-C port can operate as either USB host or USB device. Each mode supports different ways of operation.

Host mode

  • The S-4 is a host for other USB devices. In this mode you can connect a USB MIDI device to the S-4. For connecting multiple MIDI devices you can use a USB (2.0 or 3.0) Hub.

Device mode

  • The S-4 is connected to another USB host, eg. a computer. In this mode, the S-4 operates both as a USB Audio and MIDI device.

It is not possible to connect the S-4 to a computer and another USB MIDI device at the same time. In this scenario, connect all equipment to the computer and route the MIDI to the S-4 from a DAW.
