using software like that would kind of defeat the purpose of learning solfege--besides if you know the key signature...you know where do is...and the subsequent scale degrees. If you don't know your key signatures... start there.

it is the process of figuring out where "do" is and applying the syllables that teaches you the system. Eventually, you will be able to apply the correct solfege syllables to any melody you read--or hear. i.e--you will hear "Twinkle, Twinkle, Little Star" as Do-Do-Sol-Sol-La-La-Sol..etc. Then--using your knowledge of key signatures you can write or play said tune in any key. It comes in VERY handy ..
