i have noticed that without midi filters which means that midi clock is present, keys do not stuck.(only on standard pc)
whan i was in acpi and i was using the filters(without midi filters the pc freezes on acpi) the keys would stuck sometimes.
is it true that clock can be good sometimes?
stucking keys
MIDI Clock is fine as long as there is no feedback loop. Feedback happens when some devices send back to their output any MIDI Clock event they get from their input. With an improper MIDI signal chain, those events can get sent back again to the device, with more MIDI Clock messages getting generated a fairly high number of times per second. This overloads the MIDI connection and will cause crashes.
If the devices you send the clock to don't re-broadcast that message back to their output, there's no problem with using MIDI Clock, except maybe that it adds a fair bit more messages to the signal chain, which can overload it a bit if it's already crowded with lots of CC/notes.
I can't say I've ever had stuck notes in either Standard PC nor ACPI, so I'd say your issue was more routing-related.
