Are you trying to show music on screen with audio playback? Package them together on YouTube and send a link to your kids. Solved.
Are you trying to play music at the same time as students? You will need to ignore what you hear from the students due to latency. If you play with a metronome, however, the students will be able to play with you (albiet observably late from your end).
Are you trying to conduct a rehearsal? Good luck.
