Choosing Pro-tools for MIDI

[martella]

I have been a Sibelius user for some time and I don't know what I would do without it.

I am in a worship group and write backing tracks for worship songs for us to play in services. I have to convert the Sibelius score to MIDI, which we then load onto our keyboard hard drive (RolandG70).

My current MIDI software has served me well but I'm considering going to a Pro-tools product as I understand they are closely linked with Sibelius. The problem is, I don't know what to choose.

We fund our own equipment, so I'm looking for a good, budget system. M-Audio, Pro-Tools - I don't know where to start.

Can anyone please advise me on how to proceed and what would best suit my needs?

Thanks
