Hello fellow SP-606 users...

I have a question that hopefully you guyz can answer...

When using the 606 as a soundcard for my e-Mac, I was having trouble using my MFX1 and MFX2 on the streaming audio...but, the Mastering button was working just fine...

Why was mastering, (which is an effect for the most part), working while my MFX 1 & 2 were not???

hit func and mfx assign and see if its assigned to IN meaning itll be dark. that might be a reason...peace

You can set the 606 to apply FX to incoming audio; I can't remember which setting it is though - I'll check when I'm in front of the machine.
