this is the first time I'm posting in the CS80V forum, I have done a lot of patches for the Arturia Origin (http://forum.arturia.com/index.php?board=49.0
) and in January I had a breakthrough of sorts, because there was a fantastic thread on Gearslutz, where Swedish master synth restorer Ulf Soderlund restored Benny Andersson's (of ABBA) legendary GX-1 to full working condition. An extremely challenging task, and there are only a few GX1s in existence today. Not only that, but he took the time to post sound demos and explain in detail the inner workings of the GX1.
Here is the thread: https://www.gearslutz.com/board/electronic-music-instruments-electronic-music-production/1042036-yamaha-gx-1-alive.html
This gave me the information I needed to emulate the GX-1 on the Origin. I posted patches and sound demos over on this thread: http://forum.arturia.com/index.php?topic=86637.0
I got a lot of positive response including Mr. Soderlund who posted side-by-side audio comparisons between his GX1 and my Origin patches, in the Gearslutz thread. Some people asked if I could port them to the CS80V, so I am attaching my first GX1 patches to this post.
This is a CS80V2 bank that contains two presets, GX1_1_L and GX1_1_R. Load each one into a separate track in your DAW, then pan one left and the other one right (in my Ableton Live I have Left panned to "9 o'clock" and Right panned to "3 o'clock"). This is the voice structure of the later-model GX-1s...it's like playing two CS-80s simultaneously (one left one right), but with a global LFO controlling PWM on both. The patches are slightly different (as it would be on a GX1), which produces a richer sound. There are no FX on these patches, to emphasize how lush this sound is all on its own. Also, since the PWM LFOs on each patch are MIDI-sync'd (to simulate the GX1's global PWM LFO), to get the right pulse width modulation speed, I set my DAW to 94bpm.
The following demos were done on the Origin, but the CS80V patches are almost identical.
