I have to use tone wheels 1 or 4 because A4 note on tone wheels number 2 & 3 are out of tune.
tone wheel
2 1960 A-100 #4444 A4 key appears to be audibly out of tune
3 1956 B-3 #63822 A4 key appears to be audibly out of tune
Wish IK would check and correct the tuning of these two tone-wheels samples.
A4 key when using tone wheels 1 and 4 are OK.
