I am looking at getting the Core 2 specifically for having the note displayed when you sing, just waiting to figure out if it can work like that, once confirmed I am pre-ordering.
I have a small device now that does this, a Korg Vocal Tuner (VPT-1), you sing a note and it says the note/key. If the Core had this I’d be ordering now, and I’ll preorder the Core 2 if it has something akin to this, does not need much of an interface beyond saying the current note ( and some indicator how close you are to being in tune to it ).
The Korg Vocal Tuner, it shows the notes like sheet music, showing also when you are off, this is helpful as well in figuring out how to read sheet music. It might be interesting if the device was able to show the notes, the chords even, to help in transcribing more accurately as well. So if you had something you weren’t quite sure, this would give you an actual measure of it which you know is accurate. This would allow this device to have a new feature.
