Hi all.

I have a classical piano background and I plan to switch to Electronic Music, using :
- 1 keyboard with MIDI output
- connected to my PC soundcard MIDI port
- 1 MIDI software for expanding/sequencing

But I don't known if I must buy a master keyboard or a Digital (portable) Piano ?

Digital Piano has advantage of having a piano like touch, but master keyboards
have a supplementary port : MIDI through !

So my question is : Do I need a MIDI Through port in my situation ?

I readed that midi port is for connection to an external device to send and receive
back MIDI data : is it correct ? And what is it for ?
