Patches/ MIDI instruments

[Shavren]

Hi fellows,

Does PTMP 6.8 or 7 include any patches that I may use with my Kesystation 61 ES MIDI controller? (MIDI keyboard with no internal sounds) I would like sounds to use to create music, but I cannot find any to access in PTMP 6.8.

Do I have to have a synthesizer keyboard with its own internal sounds or do I have to purchase a special program that contains patches/MIDI instruments? soft synths or whatever they're called in order to generate different sounds using my Keystation?

If it is necessary to purchase a seperate program/ software, which one/company would you reccomend? I am looking for different instrument sounds that I may control with my MIDI keyboard. I am not so interested in samples/ loops.

( BTW, I would love it if someone set me straight on what they are called- patches?MIDI Instruments...?)

Thank you for your help,

Earl
