Still needs work

Nice concept app. It is nice not needing a separate sound module but the changes in the midi tracks (muting channels) don’t remain when you close out and come back. The key change remains. Also, when adding songs to a playlist, you need to scroll every song from the master list until you get to the one you need. There should be a search bar. Therefore, too many glitches to use publicly.

Doesn’t support AirPlay

I bought the full version and the list works ok once you figure out how to do it. I was surprised to find out that it doesn’t support screen sharing with audio output. I have iPhone pro 12 and latest Apple TV running iOS 14.4 but the app only will output the video not the audio. This is disappointing because I run my microphones and mix after the Apple TV. This should support AirPlay. Is that something you are working on? Or is there a work around? Since the update this is now the best karaoke player on the App Store. Thanks for being so responsive to customer service! Every other app wants you to stream and be part of a community. I just want to use my files at home for friends and family. Karaoke Anywhere used to do that but they never update or bug fix. This app does and it works and is worth the money!

Since I wrote this 3 years ago the operating systems have changed. But the app has not changed to continue to work with the current system version. I have contacted the developer by email with no response. So I am not sure if they are still in business or dead or what. This had been working great up until IOS 17 something and then quit. I imagine that with some code tweaking it could come back as the best player out there but as of now it’s useless.
Can someone please notify us customers as to the status of this developer? Thanks.

Response from developer

I am really glad you were satisfied. Thanks so much

CDG player doesn’t stay in sync

I paid for this app so that I could play and perform with CDG zipfiles of my own songs. Unfortunately, when playing many of those files it does not synchronize the scrolling or sweeping of the lyrics with the audio properly! It’s the first CDG player app I have found on any platform that fails to display these files correctly. Unfortunately, I have already paid for the app…. And when I click the menu item that says “email for support,” the app shuts down instead of supplying me with an email address for the company. May I have my money back?
