A minor downside of being able to record anything.

Just learnt a lesson on being careful regarding what tracks are armed for recording:
In the old days you chose the track that contained your VSTi of choice, rec' armed it, hit go and played and that was the end of it. Now you have to be a bit more careful.
I shifted some piano midi along the timeline so I could play some intro stuff, played it and then listened back. I was getting much more echo than I was expecting on playback (it's an "ambient" piano). Of course I then started messing with the dry/wet on the delays but it all seemed to be messed up no matter what I did.
I then noticed the audio track that had been recorded along with the midi - it was re-feeding through the FX and doubling the dosage.
Lesson learnt.
 
Grum.    

I've had related issues. One is that now that synth tracks can be recorded, I find myself accidentally recording into them instead of the MIDI track because I click on the wrong one - that can basically lose me a whole take. The other is that I used to just click record on a synth's track folder - which now records the Synth track as well as the MIDI folder. I have to pay a lot more attention to which tracks are armed these days.
