In UTILITY → SYSTEM → MIDI, select the intended MIDI Mode before checking notes. Mode A assigns banks A–J to channels 1–10; Mode B splits banks A–E and F–J across channels 1 and 2. Then use Roland’s MIDI note map for pad notes.
Try these checks
- Hold SHIFT and press pad 13, select SYSTEM, then open the MIDI tab.
- Choose the MIDI Mode that matches the controller or sequencer layout.
- Send notes on the bank channel used by that mode.
- Use the SP-404MKII Reference Manual MIDI note map for the exact target pad note.
Diagnose it
Is the sending channel assigned to the target bank by the selected MIDI Mode?
Yes: Check the note against Roland’s MIDI note map and confirm MIDI IN cable direction.
No: Change mode or send on the channel assigned to that bank.
Are you assuming one universal fixed pad map?
Yes: Use the selected mode and the current Roland note map instead.
No: Check the controller actually transmits the intended note.
What should happen
The SP-404MKII plays the sample assigned to the pad corresponding to the incoming MIDI channel and note.
Why this happens
Roland states that external MIDI pad triggering depends on MIDI Mode and directs users to the Reference Manual note map for note assignments.
