Sorry your quesiton is not clear but if you want to add more tracks/view space example I use Music Maker 16 Premium there are 4-96 tracks available I can add from.
File/Settings/Arrangement settings or click E on keyboard then choose tracks.
Refer screen shot below for help
Other screen shot where you can select number of tracks
To change view click on view and click on Standard layout or L on keyboard. If you Click again the view mode will be back to normal.
Refer screen shot for help.
Notice is the extended space
Note: you did not mention Music Maker version but I guess you can try above and see.
