Could someone please tell me what chapter to studie to learn how to make my my mo6 work with a PC? I dont have a disk I bought my mo used is thier a site for me to download the software I would need if I need any.

Yes, go here:
http://www.global.yamaha.com/download/usb_midi/

and get the usb midi driver and install it. Then the mo will show up in your sequencer program.

Then there is the studio connections.org stuff which lets you control your hardware from your computer. You don’t have to start into that right off the bat but you can.

I would recommend getting the basics down, like record your playing as midi then play it back then record the audio output into the computer as you play back the midi you recorded etc.

If your going to do audio you need an audio interface, USB, firewire, or PCI. The mo has a USB midi interface on it already.

And your going to need sequencer software like Cubase. There are some free programs out there like reaper.

Start with page 103 in the manual.

Sorry it has taken so long to thank you, but your tip definitely appreciated, thanks for your time I will try everything you have suggested
