WASAPI support: low latency recording and playback range can be 3ms-100ms depend on soundcard

2 microphones support

VST plugins support: for great VST plugins like Lexicon Native PCM plugins

2 playback modes: Exclusive mode for excellent audio quality, Shared mode for easy sharing with other player

Digital mixing: should be better than average mixer

Thanks Admin.

I am enjoy this version.

Extra feature like digital mixing "sound" nice but beyond my knowledge, stay with external mixer for now.

hi Admin please help me installing version 4. i cant even run it.

Vu, if your computer has HDMI audio device, disable that , then you can enable it again after program running and setup audio device or you can download the atom version www.karaoke4pro.com/download/karaoke4vipatom.exe and try it first

I'm not sure but I'll check once I get back home later today.

One question though, do I have to do that everytime I run the program?

Not that I could remember... I don't think I did specifically... but maybe it was bundled with .NET installation? I'm not too sure...

September 6, 2012, 3:01P


visual c++ run-time is deterrent from .net . I think you missing msvcrt100.dll

That worked!

Thank you.

Few questions

1. How do I download my songlist that I uploaded a while ago? I remember, there was an option to do that in songlist, no?

2. Where the tool to add youtube songs? I remember it was in before the release ...

Finally got sometime off so I'm back to trying to set this up :)

I can't find that link to download but it's okay, I can resetup my song list...

The other question I have is about Youtube... I could add it in the songlist but I can't play it... when I tried to play it, Karaoke4Pro crash with an error "Cannot open file"... what does that mean?

Also "online song".. i know i visit this topic so many times.. but the streaming isn't smooth.. I got the sound breaking up badly and worse in some songs... is there anything to help? please help!

youtube just changed its url structure, the fix is in www.karaoke4pro.com/download/karaoke4vipatom.exe

uncheck the autovolume may help, since some songs are very soft sound at begine so program think it is soft, but then it going strong later , this cause program overboost the volume,

so just play it without autovolume for the first time, then later you can check the autovolume

That version fixes the Youtube videos...

Yeah, the streaming sound on both Youtube and online mp3 isn't smooth for me. It used to be real smooth, oh well.. maybe some of my setting affect it... not sure what... I have the auto volume unchecked.

September 27, 2012, 2:55P


some or most of you tube and online are 44.1khz audio, did you enable resample in ffdshow or ac3filter ?

made sure ffdshow or ac3filter decode to stereo and 48khz

That's it! man you're a GOD... resample to 48Khz did the trick!!!!!!

Thank you!!! thank you!

PS: I notice one thing though, not sure if it's a new bug or anything but "Next" button doesn't work... or Play... when I have songs in the queues... I hit Next or Play (if no song is playing), it doesn't play the next song on the list.. I have to move the mouse and click on the song in the queue on top of the screen.. then it plays...

Even tried with Web Tool... same thing...
