Is there a way to record a midi track while listening to another midi track praviously recorded so that they are synchronized in Music Maker 15 Premium
I suppose you don't use a VST and your track is a native MIDI.
I don't know if it is the best way, but as you have to transform a MIDI track in an audio track (*.wav) when you want to generate the final result of your mix (wav or mp3), you can record the first MIDI track into audio (wav) in a new track and mute the MIDI previous one.
Refer to the online documentation for MIDI recording.
