MPC-HC x64 does not play MIDI files on Windows 10 Build 2004

Hello,

I recently (8 February) upgraded my computer to Windows 10, Build 2004. I discovered that MIDI files no longer play in the 64-bit version of MPC-HC. When I try, I see this error:

"MPC-HC could not render some of the pins in the graph, you may not have the needed codecs or filters installed on the system.

The following pin(s) failed to find a connectable filter:

This issue is present from at least KLCP version 15.9.5 to version 16.0.3.

I am using CoolSoft VirtualMIDISynth, but even when I uninstall that, I see the same error. I do not see that error with the 32-bit version of MPC-HC.

In the Codec Tweak Tool, under Fixes, "Fix broken sound (Midi / WaveOut)" is greyed out, with "(no problem detected)".

For the time being, I am using 32-bit for MIDI files, and 64-bit for everything else. Is there anything else I can do about this? Please let me know.

That MIDI software might haved remove some registry keys of the default MIDI renderer filter from Windows.

Codec Tweak Tool > Fixes > Re-register base DirectShow Filters
Codec Tweak Tool > Fixes > Clear ActiveMovie Filter cache

If that does not solve it then, I need to look up the relevant Registry keys, so you can check if they exist on your system.

If that does not solve it then, I need to look up the relevant Registry keys, so you can check if they exist on your system.

Unfortunately, that did not fix it.

Check if these Registry keys exist:

This is how it is on my working system:

If you remove the "HKEY_CURRENT_USER\Software\Microsoft\ActiveMovie\devenum 64-bit" then it should get re-created automatically the next time you play a midi file.

Thank you so much! Yes, deleting that key worked.
