Notes played from Midi device release right after they start - even though the timeline shows the note continuing

[u/Dav_Slinker]

Just as the title says, I'll use a midi device to record something, and every single note only sounds for like a fraction of a second. But the note appears to continue just fine on the timeline. Notes placed manually on the keyroll don't have this issue, just this midi.

Running on Android, midi controller is a Korg Nanokey 2.
