Hi
If you do multi-track recording it is best to get Cubase.
You have all you need with a program like that which includes printing out your music score.
You can also add VST instruments , do Piano roll editing.
For the Genos you do not need a Sound card or usb sound box as the Yamaha driver would put you in touch with the program like Cubase as It reads System Exclusive. The basic Cubase program would suffice just for the Genos. Once happy with basics ,you can then upgrade if you wish.
The only thing involved is a bigger learn curve.
All the best
John
