Rhapsody-2.0.1

Teacher, why does the Library.js code in Rhapsody 2.0.1 affect my Rhapsody startup speed? It takes about 20 seconds to display the software interface after each startup. How to remove the synchronization function.

@GUJIAN Starting the software interface is extremely slow without connecting to the internet, taking about 20 seconds to launch

How to remove the synchronization function.

Scroll right to the bottom and comment out autoSync()

without connecting to the internet, taking about 20 seconds to launch

I don't see a difference in speed here based on if my internet is enabled or not. Perhaps it's your computer, what CPU do you have and how much RAM. Also what OS?

Nice profile pic ;)

@d-healey

In the case of a network outage, the startup will be very slow, with a delay of more than 20 seconds before the software interface is displayed, which makes it very uncomfortable to use it selflessly.

@GUJIAN Well your computer specs look good so I don't know why it is slow for you. On my system (with the internet disabled) the start up time is the same as with internet enabled.

If you're running it within HISE you can look in the server panel and see if anything is causing a slow down (try not to spam my server too much though).

@d-healey

Releasing autoSync() still has the same issue, but the speed is still slow when the network is disconnected. Please note that

AutoSync() and updateCatalogue(); The speed is faster, but in this way, there will be problems using the function. If you turn off the key and restart the software, the installed sound source will not be displayed

[d.healey]

the speed is still slow when the network is disconnected. Please note that

I can't recreate this issue. Do you have this problem with the binary from the installer or just in HISE?

@GUJIAN said in Rhapsody-2.0.1:

I don't know what you mean by turn off the key.

autoSync()

The email I gave you no-reply@patreon.com Sent me a video, and after you watch it, you will understand why what I said is slow.

[GUJIAN]

The system has updated Microsoft. NET Framework 4.8.1 (KB5011048) for x64 bit Windows 11 and started normally again, strange

[d.healey]

@Christoph-Hart I've been working with @GUJIAN and we found the cause of the issue.

He's in China, and the great firewall blocks google.com. I believe this site/address is used behind the scenes by the function Server.isOnline()? So when he turns off his VPN he basically has to wait for the server call to timeout before he can do anything.

Is there some China friendly method that could be used for that call instead?
