Have crash at start after nothing changed (working config, open in vim, close vim, restart, not working config)
ArchLinux, linux 5.2.0, sampler v 1.0.2

Fix:

rm -r ~/.config/Sampler

Any news on this?
The fix does not work for me.
See the same error on mac os big sur

Looks like it is because of an outdated dependency to github.com/kr/pty. This moved to https://github.com/creack/pty. And the bug was fixed with creack/pty#96
Is there a possibility that you update all dependencies and release a new version @sqshq ?
