Setup with External Gear


Using samples on an external USB drive

When inserting a USB flash drive into the S-4, a folder in the Sample Browser becomes available called USB DRIVE. The samples on the drive can be accessed from this folder.

The USB flash drive needs to be formatted to FAT32 in order for it to be used with the S-4. You can not copy the samples from the USB flash drive onto the S-4.

Can I use a USB-hub to load samples from a USB drive while using the audio over USB?

This is not possible, as the S-4 can’t be a host and device at the same time.

The S-4 can either be a host (reading from a USB drive), or a device (acting as an audio interface).

Can I sync my other gear with the S-4?

The S-4 has MIDI sync over USB and over TRS with the included TRS- MIDI type-A adapter.

The S-4 can be synchronised with an external analog clock. The S-4 can send or receive an analog clock at 24 PPQN using the rear Sync In and Sync Out connections

Press [CONFIG]MIDI for synchronisation settings.

Controlling the S-4 with MIDI

Parameters on the S-4 can be controlled using MIDI CC and MIDI notes.

The individual tracks correspond to the MIDI Channel set in [CONFIG] -> TRACK -> MIDI CHANNEL.

By default the tracks receive MIDI on MIDI Channel 1, 2, 3 and 4.

Using the S-4 as an audio interface

The S-4 provides an USB audio interface with 10 in / 10 out channels for multitracking.

Extend (available in 2.0): The extend mode makes the USB inputs and outputs available to the S-4 as additional inputs and outputs.

Using S-4 as an audio interface with a computer is CPU intensive:

  • Avoid sending many simultaneous notes to POLY

  • Avoid having high settings of SIZE in MOSAIC
