I installed pacemaker on my iPhone 6 plus. I have several playlists I have made up in the native music app. I am able to select a playlist in pacemaker, and I see a list of the songs, and the play and next buttons, but that is all. I am unable to set the transition time between songs and I don't see any way to scroll through a son. There is a button that says master effects but it doesn't seem to do anything. On my iPad air, the app is virtually invisible. Maybe I'm confused somehow. I am running the latest os 9 build on both devices.

So, you have listed few comments here which I'm not aware of, but definitely I'd love to help you and try my best to make this app work well for you.
First, do you have a Spotify account and Spotify music? What music source are you using?
This app cannot play Apple Music contents because it's protected. You can only add playlists from your music library or from Spotify Music.
Are you facing any accessibility problems with this app?
Please feel free to write your comments and suggestions here and I'll make sure to deliver them to the right people.
Good luck.

Curious if anybody has any other alternatives, due to some recent update or another making this completely inaccessible?

I would highly recommend the Djay series of apps for its accessibility and its features.

I don't really think these accessibility ratings you selected are the best, at least, for me. When I launch the app, I just hear music, Welcome to Pacemaker, and then there's nothing more.
How did you get it to work, and how did you get past the welcome screen?

Hi All.
This app was posted on May 2016, so it's been a while since I've used the app and I was surprised that the app accessibility was broken after several updates. I'm currently in contact with the developer to redesign the app or improve the accessibility at least.
For now, when you first launch the app, disable VoiceOver. Tap anywhere in the screen, enable VoiceOver and you should see a login screen. Login with your Spotify account and tell me what happens as I don't have a Spotify account myself.
I'll keep you updated as I hear from this developer as soon as possible.

An email has been sent to the developer of this app.
Please follow the developer's link posted above to post a comment or ask for support on the FAQ's list as I'm currently suffering with other developers as well, convincing them to make their apps accessible. I'll follow up with this developer and I'll keep you informed as soon as I hear from them.
All the best.

Hello all.
I recently heard from the developer of Pasemaker Music - DJ Mix for iOS. Please read the developer's response below and try to write a review on the AppStore as it may help a lot.
"Accessibility Support is important to us at Pacemaker but when we added social features to the application, during the re-design voice-over stopped working. For technical reasons, this is in our roadmap for the future to re-implement.".
