that's correct, the tune tool is for composing music to use in bitsy, there is no import feature for external filesbitsymuse is a good option if you want to use music created outside of bitsy: https://kool.tools/bitsy/tools/bitsymuse-ui/
Is that functional? Doesn't seem to add the music on its own, after viewing the relevant section...
afaik people are still using it but I haven’t tried it myself
