Virtual PRC Issues

2019-08-29 by jnardone_pdx@...

Has anyone been able to successfully run Virtual PRC lately on a MarkIV on a Windows10 PC? I'm on Windows 10 Pro, Version 1903. I've opening Chrome and IE, but every time it just down loads a prcstart.php and never executes. Latest Java, Version 8, Update 221 is installed. My PRC-100 is having issues and would not like to replace. DVKBrowser doesn't have any issues running, but doesn't have all of the features Virtual PRC has.

I should have clarified that on Chrome it prompts you to download file, but that is no surprise since Java is not enabled. However, on IE it appears to fire up Java, but nothing ever runs. If someone has Virtual PRC running, let me know. That will point me in the direction of user setup error. Thanks! -joe

What's missing from dkvbrowser specifically?  With the age of the prc, I should start worrying about this.

To all,

�� This guidance was posted by another user years ago and still works on my Mark IV, as the web-based browser wouldn't work following Java security updates during the Java 7 series. You can point to a Windows 10 64 bit version of Java 8 as well which I use, so my current target is set at

"C:\Program Files\Java\jre1.8.0_221\bin\javaw.exe" -cp prc100.jar gui.prc100 -h=192.168.xxx.xxx -p=3191 webremote -w=31910"

I have a Windows shortcut called VirtualPRC, and my Icon "Start In" parameter is set to the drive/folder where my prc100.jar file is stored.� The network address on my system for the Disklavier is a fixed private address (not DHCP), so replace xxx.xxx with whatever your Disklavier address is. You need a fixed address for this to work.

Regards

Jason

Original guidance is below:

I have an icon (shortcut) on my desktop which a target of:

"C:\Program Files (x86)\Java\jre7\bin\javaw.exe" -cp prc100.jar gui.prc100 -h=192.168.0.6 -p=3191 webremote -w=31910

and a start in (default directory) of C:\users\kevin\

and in C:\users\kevin is the actual "prc100.jar" (this is the actual prc100 program) that I had to manually download from the piano (I can probably explain how that was done, or just share this jar file since you all already have it anyway).

So, basically, this shortcut runs javaw.exe, and passes it a bunch of important command line parameters.� As it turns out, you would all need the same command line parameters (I believe), aside from the one that looks like this:
-h=192.168.0.6
as that is the IP address of my piano on my network.� You would need to replace it with the (hopefully fixed) IP address of your piano.

Assuming you are on Windows,

the "Target" of the shortcut should be javaw.exe with all the rest of the stuff you entered so, something like (I'm not near the computer that has this, otherwise, I'd just take a screen shot and upload it...)

Target:� "c:\full\path\to\javaw.exe� -cp prc100.jar gui.prc100 -h=192.168.0.6 -p=3191 webremote -w=31910"

Right under the target is a "Start in:"

if you put your prc100.jar file in "c:\some\other\dir" then your Start In should be set to

"c:\some\other\dir\"

This time I was looking to upgrade system. There was an over the air update from 4.23 to 4.25 a little while back I was putting off and the battery died on my PRC100 and was looking to use the Virtual PRC. I use the PRC for many features not available in DKVBrowser including recording, chaning temp, and changing voices.

I can confirm that VirtualPRC works if you download the prc100.jar file to your PC and run the java command line above. I use OpenJDK and didn't have any issues running VirtualPRC, but need to update some path that isn't being set. Doesn't appear to affect the operation.

java -cp prc100.jar gui.prc100 -h=192.168.1.100 -p=3191 webremote -w=31910

error is ==> "\proc\deviceinfor\locale (The system cannot find the path specified)"

OpenJDK being used (java -version)

openjdk version "1.8.0_212"

OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_212-b04)

OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.212-b04, mixed mode)

This is probably off-topic, and maybe even moot because the virtual PRC exists, and we can still run it...however:
I agree that DKVBrowser doesn't support recording.  It always seemed like too big of a burden to require a PC near the piano if you were going to use DKVBrowser to initiate recordings.  Now, in hindsight, if we are going to have the same requirement to run the virtual PRC anyway, I probably should have added it.  Oh well.
But, what does "chaning temp" mean?  Changing tempo?  DKVBrowser certainly supports that.  Unless there is a bug I am unaware of?
And the same goes for "changing voices".  I'm fairly certain that's in there as well.  Maybe you just haven't found the "view" that supports these features?

Correct. tempo and voices are supported in DKVBrowser, but since I was occasionally using record I'd always power up my PRC100 anytime I used for non-library playing without not even thinking about it. For all playback I have and continue to use DKVBrowser from my PC. Thanks for great app Kevin!
