In short, please bring crossfades to the backing track player part of the show page! Bonus points for custom fade times and types (linear, exponential, etc). Super bonus points to bring crossfades to the instrument players for crazy sound design!
I'm using the Studio One Show page for live church services. While I've been pretty happy with all the options it provides (loving some subtle, real-time autotune), having smooth, (hopefully customizable) fade transitions between setlist items would be fantastic! It's one thing to fade a backing track down in the house, but the in-ear system will still hear the next setlist item change aburptly. Having just the backing tracks crossfade on click (perhaps following the already available options of 1 bar, 2 bars, etc) would allow us to have continuous sound instead of clearly defined song starts and ends.
Of course, having a good pad player would be better for multiple reasons, but not everyone has a giant volunteer base to pull from. Crossfades between setlist items would be really cool for warping instruments too but I imagine that would be crazy complicated to implement compared to relatively simple backing track crossfades.
For instance, fading options between the exact same elements in an FX chain theoretically shouldn't be too bad but what do you do if the chains are different? Is it possible to fade out an effect while simultaneously bringing in an entirely different effect? I'm not a programmer but that sounds hard to pull off well. Setting all currently available automations to zero while maintaining ratios to preserve tone while also bringing in new effects from zero to the desired and programmed levels on every instrument track seems like a gargantuan task.
I'd absolutely be happy with just backing track crossfades (and that's all I'm asking for) but one can dream, haha.
