Need help with Orpheus? You’re in the right place!

I’m using Dropbox, do I need WiFi ON?

Yes. You will require an internet connection to access files stored on Dropbox.

This was not always the case. More info here.

The first time you load a chart, Orpheus saves a copy to your local cache. This allows much faster access to that chart in subsequent viewings. When you make annotations, they are stored as a separate layer in the cache and do not affect your original copy of the chart on Dropbox.

Any changes you make on Dropbox will be pulled down to the app next time you open the chart.

Cache Everything Now Option
If you expect to be using Orpheus to access Dropbox files a lot and want to speed up the loading, go to Settings where you will find a handy option for “Cache Everything Now”.  Do this at a time/place where you have a good WiFi connection. It will do exactly like it says – cache all your files.

In this way you can be confident your charts have all been cached, and will therefore load quickly in the future without any delay.

Is there an offline mode?

Yes. It’s fiddly to set up, but once configured it works nicely. Tutorial here.

How long would you expect cache everything now to take. It has been going on now for nearly 2 hours.

This depends on how many files and folders you have in your Dropbox account. When I did mine – 4 folders each with around 200 PDF files – it took around 20mins. But in our tests we also found it depended on what else you have in your Dropbox account (even if it is unrelated to Orpheus). I would suggest plugging your device into power if you have not already done so, and leaving it overnight to complete. If it’s still not done in the morning, let me know and we can investigate further.

I’m loading several hundred music files to the cache and it’s been almost nine hours and not finished. I’m hoping this won’t be an all- day task each time I want to clear the cache and rebuild it. I love what the program does, but it’s taking longer than a “brew” or two.

The time it takes to cache depends on how many files are in your Dropbox. It’s actually not within our control on the Orpheus side either – it’s down to the Dropbox API. If it’s taking excessively long try caching in smaller batches eg add one folder then ‘cache everything’, then once that’s done add your second folder and ‘cache everything’. Another thing we’ve seen a few times is that a corrupt PDF file stalls the cache process so it gets stuck. This can be particularly frustrating as it’s hard to find exactly which file is the culprit. Again, breaking it into smaller batches will help you narrow that down. Hope that info helps.
