Small bit of pricing feedback, maybe you could consider it for ST4.
I finally convinced my singer that using my StageTraxx 3 session for lyrics was going to be more accurate than his app (not sure what app he uses, but sometimes it's slightly different than the tracks).
He agreed to try it out, and was immediately asked to pay $25 to join a session. I honestly thought this would be free for him. I convinced him to pay anyway (since the app is well worth it), but honestly it seems like the unlock price should probably be more expensive for the main unit, and free for those who join. For instance, maybe there's a version that doesn't have sessions, and a more expensive one that does (but the viewers are free)
Thoughts?
