Routing

The S32 can send and receive MIDI on several physical and logical paths.

Physical ports

Port	Typical use
USB	DAW on computer (MIDI in and out)
MIDI In / Out 1 / Out 2 / Thru	Hardware synths and drum machines (TRS + included DIN adapters)
USB Host	USB MIDI keyboard or controller plugged into the S32

Virtual MIDI A–D

Virtual ports are internal cables between racks in the same project.

1. Add MIDI Output at the end of rack 1.
2. Set Output to Virtual A (or B, C, D).
3. In rack 2, add MIDI Input (or start chain with devices that accept note input).
4. Route rack 2’s MIDI Input from Virtual A.

INFO

Messages go rack → virtual port → other rack without looping back to USB unless you choose to.

USB Host

Select USB Host as a MIDI Output destination to drive gear connected to the rear HOST port — useful for controlling a USB-only module from a rack chain.

MIDI Output device

Every chain that should produce audible MIDI needs a MIDI Output device. Its Output parameter picks:

• USB
• MIDI Out 1 / 2
• MIDI Thru
• USB Host
• Virtual A, B, C, D

Thru vs processed out

INFO

• MIDI Thru passes input unchanged (hardware-style thru).
• MIDI Output sends the processed chain result.
