No not exactly, I think only serial configuration will be possible with neighbour tracks. For the most effect you’d need parallel filters. Anyway, already one voice of the A4 can give you a lot of movements and resonant shimmer quite similar to the characteristics of a multiband filter found in the Syrinx. It gets a bit harder when it comes to formants but it’s not impossible.
Whats far more critical here is what has been already stated above, the characteristics of the overall sound is very different. The Synton Syrinx has all that smooth vintage vibe to it. The A4 can do this to a certain extent, but always is a bit on the harsher and harder side. Mostly because it allows a wide range of control and is not limited to a small set of sweet spots. So you have to do more programming to get results for the benefit of being able to achieve a greater variety of sounds.
To my taste the A4 is very good at all things short and percussive. Moving resonant pads and drones are on the other side of its more easily reachable spectrum. The bread and butter patches for more vintage sounding filtersweeps and resonant basses etc can take their time until they come close to what on would expect the to sound like in their full richness. But that’s also true for most older digital synths and VAs. So not much lost if you’re used to that. And the A4 gives plenty possibilities to try new things out and explore unexpected sounds and results and dig quite deep into sound design.
