1. Create a track and open RS5k on it.
2. Open the Media explorer and make sure "Assign detected pitch when inserting into sampler"
and "Show/hide pitch detection" Media explorer options are turned on.
3. Find a sample that's tuned to some note below A5.
4. Play the sample and then use the "Media: Insert into active sample player" action.
5. Working correctly.
6. Find a sample that's tuned to some note above A5.
7. Again, play the sample and then use the "Media: Insert into active sample player" action.
8. Working correctly.
9. Now find a sample that's tuned to A5 (accidentally joined the next step with this one in the gif above so that's why the subsequent step numbers are reduced by 1 in the gif).
10. Again, play the sample and then use the "Media: Insert into active sample player" action.
11. Still working correctly.
12. Reset RS5k to factory default.
13. Play that sample that's tuned to A5 again and use the "Media: Insert into active sample player" action.
14. It doesn't detect the sample's pitch.
Additional notes: The same issue with a sample that's tuned to A5 can be recreated if you just use the "Media: Insert into sample player on a new track". The whole procedure above was to show that it works correctly if the A5-sample is not inserted in the sampler first.
