Once into a recording session, after a while S1 will no longer record. I get meter deflection showing a signal is getting to the software, it just does not record. MIDI always seems to work fine, this is from inputs from my Focusrite 18i20. Start a new recording session and everything is fine - for a while. Very frustrating. All my issues began with the 3.5 update. Recording software that won't record is no longer recording software, it's garbage.
