MOTU M2: remove software input delay while retaining a known MON path
MOTU M2: remove software input delay while retaining a known MON path. Check prerequisites and the actual response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
The input is already audible through MON, and software duplicates it.
Connection scope: USB audio. Symptom: Sound and picture are out of sync.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is the input already audible with its blue MON indicator visible?
Do not disable the only input monitoring path.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Do you want the clean direct input rather than live DAW effects?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
Do you want the clean direct input rather than live DAW effects?
A software amp/effect chain will not be heard on the direct path.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → May that DAW live-input monitoring be disabled?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
May that DAW live-input monitoring be disabled?
This changes monitoring rather than recorded hardware gain.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Disable live monitoring for that DAW input track
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Disable live monitoring for that DAW input track
Keep its known hardware MON route enabled; do not toggle an already enabled MON button.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Is the unwanted delayed or doubled input removed?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Is the unwanted delayed or doubled input removed?
No measured round-trip or repair result is claimed.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

Possible result
Checks completed — report what happened
Completion is not an automatic solved result. Report solved, partly helped, did not help or could not follow based on your actual observation. No Audio Review physical test is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Keep these observations for official support
A required prerequisite or response was not confirmed. Stop this sequence and use the exact model and partner documentation. Do not escalate to a factory reset, firmware installation, internal repair or unsafe wiring change.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
A required fact is unknown
Confirm the exact model, connection, partner capability and current control state before continuing. Do not guess settings or operate an updating product.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
