[Coco] Orchestra Master 1.1

[coco at jechar.ca]

All

I have the Orchestra Master 1.1 disk and created a file to play
with my Orchestra90 but how ?
Orchestra Master 1.1 creates .ASC or .MUS files which the
Orchestra90 does not list. I know that the Orchestra90 files have
no extension but how do I convert that to a file the Orchestra90 can 
read ?
There is no documentation with the conversion program included on
the Orchestra Master 1.1 disk so could someone explain how EXACTLY it is 
used.

I have a file I created with Orchestra Master 1.1 named
TB.MUS

I want to create a file called TB that the Orchestra90 cartridge can 
read can I do it with this conversion program?
If so how ?
If not then what do I need to make this conversion.

Thanks
Charlie
