Coming from Mixcraft, I've found that tuning when recording is quite a task in studio one. Made more frustrating that I have to be monitoring my input for it to work.
Mixcraft: click arm track to record with whatever input you have selected > click tuner button (you don't need to be monitoring the input either which is great if you have latency issues)
Studio one: click to arm track with input selected > go onto faders section > add insert, look for or type tuner to add on to the fader > open that tuner up every time you need to re tune. (then do the whole process again for every track you need a tuner on)
This would be so great to have as Im sure many people would like to be able to just hit record and hit a tuner button on the track list in the way Mixcraft does this.
