Why can’t I get the notes out of the re.corder?

When playing re.corder in digital mode a “clean” fingering it is definitely needed. But don’t worry, you’ll get used very quickly.
It is important to keep the fingers of the right hand away from the touch sensors. So you will have to get used to not touching the D5 or C5 or B5 by keeping the fingers of the right hand on the holes.
Please be careful to rely only on right-hand thumb and lips to “hold” the instrument.
A suitable resting position for your pinky is half an inch toward the bell end. This allows you to balance the instrument and not interfere with the fingering detection.
