Nils Jonas Norberg, Jörgen Arvidsson, Nico Herz and the Others...big respect for this Synth.
I boubht Helix just 2 todays ago !

The last Reaction in this Plugin was 2018. So hopefully we hear again...

I read a bit around here and found some issues, but i speak only for myself and my feelings about HELIX, additional with some user comments.
So when Audjoo is alive and also working as Coders, then maybe we can get a revival of Helix.
Some ideas, wild mixed with issues, cosmetics and logic mistakes:
1. Import a RANDOM Function for Filters, OSC, Env, FX each optional, so that we can explore sounds we only can build in decades
1.1 random mix the MATRIX (optional only actual), clear complete matrix or each line separatly
2. resize option the whole GUI, some cant get the full GUI, for me in FLStudio no GUI
2.1. enlarge the FADERS in OSC and Matrix-Section, also the TEXT next to it, and these tiny ARROWS inside the tiny Boxes, i only find with the magnifying glass
3. make Sections more visible different/separated (OSC, section, Multi to Shaping, EG)
4. renaming EG to ENV ,Multi to Unsion (you say its is similar to Unsion while layering?)
5. double click Buttons and FADERS to RESET
6. optional editing Faders and Knobs with Mousewheel
7. Make some GAIN-Knobs to ZERO, mostly on 0.125 (some more knobs dont reach ZERO)
8. Dropdown Menues are annoying if there millions of stuff inside (e.g. #6)
9. (Done)
10. Maybe the Waveshaping Section can be more efficent or less options
10.1 It should looks better if the Wave Visuals are between the A and B Shaping
10.2 Draw-able Waveforms and Envelopes, with a GRID
11. stretch a bit the16 Sequencer Steps
12. make Sequencer Steps drawable
13. make setting for Step lenght and Loop Start not in pulldown menues
14. Mouse over Information
15. Make a Preset/Patches Section inside the Plugin (like u-he Plugins)
16. Not sure why the CC Section have only 4 Options available, the others are grey
17. Modulations on some Effect-Params
18. Pimp the Analog Oscillator Type
18.1. Pimp the Noise Ocillator Type
19. SEQ2 is not available as SOURCE, but SEQG1 (G1 = SEQ2?)
20. Loop Start/END begins at 0 and ends with F (better from 1 to 16)
21. Bi-Polar Knobs and Envelopes are a bit confusing.
And Optional a nice HELIX animation behind the Big Fader (watch to SonicCharge - Synplant)

Okay.
Regards.
