Inna, you seem to be an expert in Arab Flamenco, and all the other types of Flamenco as well, could you submit some of those; especially the one's with pretty pictures.
BTW, I was reading and listening to music, and I thought "The rig is sounding very good today" when I thought I was listening to CD, but it was the 2 track playing. That lets you know how much better it is than any other source.
The 4 channel Otari is not 2 track and it's also overkill, extremely complex. Costs 2K to turn it into 2 track, plus that clutch makes it out of bounds for the time being.
Wish you luck with your project.
Enjoy the music.
