Summary0001459: OpenMPT's sample rate affects plugin's sound velocity
Description

If you change output sample rate it will also affect how the plugin (helm) sounds. I don't know is it a bug in the plugin or in OpenMPT. It doesn't happen with other plugins though.

Steps To Reproduce

See the video: https://youtu.be/jlJ9jzCf7hs

Yes, there is a number of plugins that

  • Don't like the sample rate to change once the plugin was loaded into the host
  • Assume a hardcoded sample rate of 44100 Hz

As you correctly observed, many other plugins don't have a problem with this. It's a bug in the plugin and needs to be reported to the plugin author. Since in your example the sound is still correct but just the tempo of the arpeggio is wrong, it's quite clear that the plugin does receive the sample rate change, but it doesn't apply it to all its components (oscillators are fine but arpeggiator is bugged).
