That's strange. Maybe fiddling around in your system prefs _before_ starting/restarting supercollider + superdirt would help.. It could be that the default input is set to a bluetooth device, or something like that. ---

Yeah it looks like the issue was that when I was in Ableton the input was set to no input... I switched it to built in input in Ableton and it worked again! Thanks šŸ™‚ ---

Hello @yaxu I know that this issue was already pointed out, and probably there is a simple way to resolve this. But, every time I start Atom that message appears. I have sound and Super Collider is working fine so I suppose it's not a big deal that error. I didn't try those command lines in the terminal because everything is working and I'm afraid that I mess things up if I change that. So, my question is, if everything is working I should't worry about that error, right? I'm on a MacBook with Mojave 10.14.6. P.S.: I'm on the first week of the TidalCycles course and loving it šŸ˜„ Thanks and all the best. ![Screenshot 2021-01-13 at 10.00.22](https://club.tidalcycles.org/uploads/default/original/2X/a/a19e09f1fb209e98e63a92075181c8b9587c5723.jpeg) ---

Yes that would get a bit annoying. In atom preferences, are you on the latest version of the tidalcycles package? @ndr_brt has been releasing a lot of updates lately. But yes if everything is working you can ignore that, the only error is that it is treating some information as if it was an error. ---

That message appears for two reason: - a feature that shows the error messages on the console as atom notifications (that can be disabled in configuration) - that string is printed on the stderr by ghci (don't know why, it should be on stdout, it's a simple information) ---

I just found (by trial an error) that `ghci -v0` does not print the startup message and banner. I have not idea what `-v0` would change in a ghci session. Tidal seems to work fine. Flag reference: [https://downloads.haskell.org/ghc/latest/docs/html/users\_guide/using.html#ghc-flag--vāŸØnāŸ©](https://downloads.haskell.org/ghc/latest/docs/html/users_guide/using.html#ghc-flag--v%E2%9F%A8n%E2%9F%A9) (it says that -v1 is default for --interactive, that is, ghci) ---

Hello, and thanks for the quick reply. I did the update of the TidalCycles package on Atom and now there's a new warning! But i still have sound and Super Collider is working fine. šŸ¤” So, for now I think it's OK because I'm able to do everything in Atom and generate sound. If that situation changes I'll definitely ask for help. ![Screenshot 2021-01-15 at 14.36.27](https://club.tidalcycles.org/uploads/default/original/2X/8/80a0d3f18414cbad4ca5c371a10579d1ef98c506.jpeg) ---

Woa, nice! It's a pity because startup message is useful for troubleshooting... ---

for some reason your ghc-pkg does not understand where's tidal installation directory... that information is used for obtain the `BootTidal.hs` path, maybe that's more like a warning instead of an error, will correct it. ---

Released the new version without the `Cannot obtain data-dir` error. About the ghc error... since I updated it to 8.10, the log stopped appearing ---

Hello there! I had exactly the same "Execution warning: Class 'Vowel' not found ERROR: Message 'formLib' not understood." error... and the "include("Vowel")" + recompile did NOT work... I still get the same error in supercollider when I try to run superdirt... Any troubleshooting suggestions? ---

Hm, that's strange, I'm not sure why that happened @Ouyuegu, maybe you had a network issue while it was downloading? To troubleshoot, you could look in the folders to see if the Vowel quark (add-on) is actually there. From the supercollider menus, it's File -\> Open user support directory -\> downloaded-quarks. There should be a Vowel folder there. If you're familiar with 'git', it's a git repository, so you could try diagnosing the problem from the commandline. Otherwise, you could try downloading the quark manually from here: [https://github.com/supercollider-quarks/Vowel/archive/refs/heads/master.zip](https://github.com/supercollider-quarks/Vowel/archive/refs/heads/master.zip) . It will uncompress as a folder 'Vowel-master', you'll need to rename it to Vowel and move it into that downloaded-quarks folder (deleting any existing folder). ---

Yes! Manual downloading worked perfectly. It seems that my install of Tidal had only partially populated the downloaded-quarks folder... We live and learn. Thank you! ---
