6 Funk/Jazz Fusion IDs - 1983-84

[hightype]

These IDs come from a South American themed mix (mixed by Dubby):

As the title suggests, these tracks are most likely from South American artists. The sound is typical to the years 1983-84 (maybe early 1985) - Yamaha DX/FM bass, leads and sequences atop a Linn LM1 or LM2 drum machine. It is probable that most samples come from the same artist. I'd love to listen to music with this sound so if anyone has suggestions of similar albums or artists, it would also be very much appreciated!
Thanks in advance!

I'm bumping this topic... I have an idea - ID #4 has lyrics in either Spanish or Portuguese - if someone who understands could make it out, it would be much easier to google it (or even figure out the track title from the lyrics).
ID#6 has been identified in the meantime (on MixesDB):
