OP-1 Fade in/fade out

Is the only way to fade in/fade out by recording and turning the orange volume knob?

Also, follow up question

How do you get the OP1 to start recording on tape mode when I start playing the keys? Right now I’m over stretching my hand to hit the play button while simultaneously playing the keys and I know there is a better way but I couldn’t find anything online about it

just hold rec button and start playing some keys
the tape will start automatically and record will latch
