If keyboard disappear and midisrv don go, I dey start Windows MIDI Service. I no dey disable enhancements on audiodg as my first MIDI step.

## Wetin make am dey run?

One DAW, piano app, or MIDI device open client. PC wey no dey ever use MIDI fit still start di service after pesin plug device.

## Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

`Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'midisrv.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List`

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the [file-identity guide](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Check dis running file

System32 midisrv.exe na Microsoft. One midisrv.exe inside VST folder no be di Windows MIDI service. audiodg.exe na still di graph.

## Common wahala dem

### No sound from soft synth, MIDI still dey light up

Di synth output na audiodg / di audio device. Dis service only carry MIDI.
