I'm 100% on board for more synth stuff. We have enough amps and effects unless they wanna throw us some more ambient/experimental type effects like glitching and stuff! To be honest I'm quite a bit let down about it not having more synth stuff considering how guitar synth stuff has exploded lately. I have a boss sy-1000 and gk pickups and can use external synths like my hydrasynth and wavestate etc... with it but it would be nice if helix got in the synth game. If helix could do great synths it would be powerful with that and variax. It would be a boss sy-1000 on steroids where you could conjure up awesome synth tones, acoustic guitar stuff, alt tunings, different modelled electrics and bass etc... I can do all that with sy-1000 but I'd love to be able to do it all in helix instead and be more powerful with 4 signal paths (instead of 3 in sy-1000) and more fx blocks in helix 32 (instead of like 15 in sy-1000) and helix routing and fx loops and stuff would just make it a killer over sy-1000.
If helix got to the point of having strong polyphonic synth options that are great I would drop my gk pickups and sy-1000 and get my a variax but it would have to be much better than sy-1000 before changing. Able to sound good, split strings, great alt-tunings, good filters etc..
