Question

• Your Computer Make and Model: Sweetwater CS250
• Operating System and Version: Win10 64
• Application Version: 3.5
• Audio Interface and it's Driver Version: Soundcraft Ui24R - driver "UI Session Maker" (no version shown)
• Digital Mixer and it's Driver/Firmware Version: Soundcraft Ui24R - 2.0
• What is the setup and what were you doing that led up to the error or situation is that brought you here: I have 9 mics on my drum kit, all going through UA & Sytek external mic preamps. These are connected to the inputs on the Soundcraft Ui24R which is fed to the PC via USB. All channels work perfectly during recording and playback. The problem, which has occurred on & off since I purchased Studio One several months ago, only occurs during export, which is configured to run between start & stop, though I've also tried between Loop. As soon as the EXPORT process begins, the mute button of channel 1 (which is always the bass drum) suddenly lights up. When listening to the exported mixdown - no bass drum. I've tried again after hitting SAVE, after restarting Studio One, I've also tried defeating the automation. Still the problem persists.
