Hi, I have some problems with SD 3,1,0 beta 2Beta with the Oberheim Marix 6 Rack. I use OS X 10,4,6 and an Emagc AMT8. From memory, everything woks fine under OS 9 but with OS 10 it's a nightmare. The synth is not auto scan but seems work in manual scan. I could receive all patches in the SD window (with some 'times' adjustment) but when I send a patch to the synth, I always stay on the 99 Patch. The memory protect switch is of coarse off. The editing window works (maybe partially) and I could hear the manipulation. IMO the soft is lightly buggy and I become seriously crazy. Any help will be much appreciated, Lucien
