Revised 5/10/16
I am a long time user of this app, and my band is completely reliant on SLM for our performances. It controls everything, from playing the drum backing track, setting the guitar effects presets and vocal harmonizer presets, displaying and scrolling the lyrics on the other musicians iPads. It did all these things, and much more, flawlessly, up until a little over a year ago, when things started degrading.
We used to be able to link or iPad over Bluetooth, but after one of the updates, that feature no longer worked and we then had to pack a WiFi router along with us, as that is the only way we can now link the iPads for lyrics display. Arlo blamed Apple for the Bluetooth failure, and I believe him, but it shouldnt be listed as a feature if it doesnt work.
When we started using the WiFi, a new and more serious issue arose. Occasionally, on stage, right in the middle of a song, the app will crash! The music stops, and there we stand looking like deer in the headlights. Embarrassing, to say the least. This had been happening occasionally for just about the past six months. After several troubleshooting reports, Arlo told me that he thought he knew what the problem was, but considerable time would be required to find a fix. This was back in January. Still no fix. Still getting occasional performance failures, but very intermittent.
Dont get me wrong. This is an amazing and powerful tool that we have built our entire performances around. This is unfortunate in one aspect. We are so dependant on SLM, that we could not go out and do a gig without it.
I see several reviews here I wouldnt agree with. I dont think it is all that expensive with the add ons. For the features it offers (when working normally), there is no other app that even comes close.
