Denis,
Hello and yes, there is a lightweight module which has both great jazz and turkish, greek and arabic styles. It is made by Generalmusic and it is called the WK2orientalArranger module. It has 48 dedicated middle eastern styles with 4 variations, 4 intros and 4 endings but it also has dozens of pop, jazz, swing, latin, dance, waltz, polka, etc. styles. There are over 400 sounds and you can edit and create your own styles. Quarter tone tuning buttons for each note are on the front panel and there is a floppy disk drive for playing smf right from the disk or saving and loading your own stuff.
I sell this module at my music store in California. I sell the module for $995.00 US dollars. You should be able to find it somewhere in Canada I would think. Generalmusic is in Chicago and you could contact them directly and ask if there is a dealer in your area. They have a toll free 800 number. I am at home and don't have it right now.
