Hello VideoPrince,
Thank you for contacting NCH Software. You will find that .imy (iMelody) files aren’t digital representation of an analogue sound track, but represent points in time where certain notes / instruments are being played, much like a .midi file.
As with .midi, Switch cannot convert to .imy. There are other pieces of software around in the market that claim to be able to do this, though in my experience, work with limited success. If the track you are trying to convert is relatively simple, you’ll have greater success.
Good luck
Regards
