Devices that reproduce the issue

Not device specific, so emulator, Pixel etc...

Devices that do not reproduce the issue

No response

Reproducible in the demo app?

Yes

Reproduction steps

Using demo app with MidiExtract and MidiRenderer
Open a MIDI file
Seek forward in the file, and all channels are reset to default program (usually Piano)
Seek backward in the file, and all channels are properly configured back.

I've put some logs, and it seems indeed, that when seeking forward, MidiDecoder reset the Synthesizer but never sends the PROGRAM CHANGES events, but does so when seeking backward.

Expected result

MIDI channels are properly configured back after seeking forward

Actual result

MIDI channels are reset to default program (Piano) after seeking forward
