I was happily using Studio One 4 for a while when suddenly it stopped recording from any device.
My track has an instrument on it, which can be triggered by the device, and is armed for recording, but when I record it just creates a red track, records nothing, and disappears afterwards. Here is me using the QWERTY Keyboard device to show it's not just my MIDI devices at fault:
Any ideas? Have I accidentally changed a setting somewhere? This is really frustrating! Thanks
