Ok, so here's three things I'd love to see:
1) I don't tend to use the sequencer much, and it would be good if I could assign the knobs to parts of my synths instead of them just sitting there idle. This is a no-brainer for me if its possible, as I find myself always running out of assignable controls.
I could have extra oscillators, filters or envelopes ready to control, and it would really speed up my workflow on the Origin.
Also if you could assign a control that is default for any preset, I'd find that really useful. For example, 9 times out of 10 I boost the TAE in the program page, but its fiddly, and would be good if one of the assignables was just set to this by default whenever I load a patch.
2) I totally agree with JacksonP that a better visualization of the screen when the Software Editor drops would be most welcome.
I love the Jupiter 8 Temp, but its so fiddly, and I imagine the CS-80 will be the same. Be good just to see an overview of everything on a big screen. I am simple and need help.
If we could even make graphics for our custom Templates that would really bring this baby home for me. That would be incredible!
3) Lastly, I'd love to see some more modern options. Don't get me wrong, I am all for Oberheim and Prophet V modules, but I feel like I've got enough vintage in the Origin at the moment to get on with. A few more Origin own modern/digital options would be a big step forward for me. At the moment I use Camel Audio Alchemy or my Waldorf Blofeld for this kind of sound, and occasionally the Prophet Wavetable Osc (which is exceptional).
An audio sampling module to open up the sample based synthesis options maybe? Would take over from Alchemy for me.
Maybe even a module that lets you draw your own Wave shapes? I've got an ipad app that does that and its really interesting.
