Of course, @sbarbit !
But you better improve the current audio player, adding the “rubberband” and “looping” features. The current one is really basic and deserves some love.
There is already a rubberband LV2 plugin. It’s not very usable though. I started working on a replacement audio player. It should be in a development branch of GitHub. I had planned to get the player working then add a sample looping feature to sequencer as requested by @MrBroccoli based on the audio player codebase. Maybe rubberband becomes available to both.
