I've just started using ST3 and have run into several issues. First, I'm using it for about nine songs for click, stereo keys, some percussion and some stereo background vocals.
My setup is either my iPhone or an iPad, a lighting to USB-B cable, a Behringer FCA1616 interface and either a TRS-XLR or TRS-TRS snake.
I recorded the tracks myself using a DAW, mixed them to WAV files and uploaded them to ST3.
The first issue is that sometimes the click will randomly drop out for two or three beats and comes back in. That, on its own, isn't a huge problem. It doesn't happen that often.
The main issue is that sometimes there are random very loud pops. It sounds like someone trying to plug in a cable into a live PA system. It doesn't do it every time or in the same place in the songs.
This is the issue I've been trying to resolve. It has done it with the iPhone and the iPad, it has done it with both snakes and it's done it in rehearsal and live.
The only thing I haven't changed yet is the cable between the device and the interface and the interface itself, or the outputs of the interface. I'm using 1-5 of 8 outputs. I could try 5-8 and see if that makes a difference.
But I saw that the app could be used on a Mac as well, so I thought I'd try that. It might be easier to use live anyway. So I downloaded ST3 on the MacBook and used a USB-C to USB-B cable but the Mac is not seeing the interface.
Do you know of any issues that would keep these from connecting? I was going to buy a Firewire 800-400 cable to see if that would work.
