Re: Marion Systems Tom Oberheim SEM Plus
Sounds like he's hinting at a programmer in the works.

Re: Marion Systems Tom Oberheim SEM Plus
Gibson has the rights to the Oberheim name and strutting logo trademark. They licensed it to Italian instrument maker Viscount for a while. They made the OB-12.

Re: Marion Systems Tom Oberheim SEM Plus
Three knobs at the bottom of the VCF section: AH, I get it. They are balance controls for saw v pulse from each oscillator? So 12 o'clock would be "0"? Yes So do we know how the switches on the new one function? Could they be level controls? They look more to be on/off functions. Also notice that t...

Re: Marion Systems Tom Oberheim SEM Plus
Notice also the Aux In & Flex jacks but no routing on the panel for them. There might be a separate programmer that could access these and the mix functions.

It looks like it might fit if the walnut end pieces are removed.

Re: Korg to release ARP Odyssey
I thought they used wallwarts to get around the UL approval process.

Re: Sonic State King Korg review
Seriously though both the Radias and MS 2000 had Dwgs. I think it's really good that it has pcm's. I don't understand what your complaining about. Saw waves can become quite boring. it was an observation _not_ a complaint. My point is that King Korg has extra waveforms on all of it's oscillators wh...

Re: Sonic State King Korg review
I downloaded the manual and parameter guide and noticed that, unlike the Radias and MS2000, all the oscillators have DWGS and PCM waves. It would have been nice if they just took the Radias and put in the King Korg's oscillators and modeled filters.
