Best clarinet feeling has the Yamaha WX5 at an Yamaha VL-70m synth with the Patchman Turbo chip. The Sylphyo is a different beast. It has a soft long airflow. You can manipulate that via electronic settings and additionally attach different plugs (for blow-resistance) at the lower air-hole but basically it feels always like a flute. The strength of the Sylphyo lies in it's very special soft and precise airflow detection and in the type of available control possibilities: Air pressure, sideways roll, elevation (vertical angle), compass (sideways angle) and key-bend by rolling the finger tips. The Sylphyo has no mechanical keys and the mouthpiece does nothing. Very expressive and very different from a clarinet.
I like your music I heard on YouTube and I am not sure if the Anyma Phi is the right synth for you. Hopefully Aodyo doesn't beat me for that, but I find the sound of the Anyma Phi very synthetic. The Sylphyo has the "smaller", medium synthetic version of these sounds and the Anyma Phi does them better, if you know what I mean.
The internal sounds of the Sylphyo are not customizable. You can use the assigned controllers and that's it. But some of the sounds are a good base for an effects chain like yours.
Anyma Phi sounds are customizable, it is a fully featured physical modeling synth. The Sylphyo sends CC values from various sources that can control everything MIDI aware.
Hardware and Software depend on your musical wishes. For example, I find classic FM synthesis like in a TG77 rather boring with the Sylphyo. Generally, older synths were not built for the range of control a Sylphyo delivers. Modular systems do work but I find them too brutal for the Sylphyo's nuances. So far I heard, Roland's Integra sounds good with a Sylphyo. I have a Waldorf Blofeld and a Dreadbox Typhon and both work well with the Sylphyo but I would not recommend exactly these two because I always miss some expression and power I expect from hardware synths.
Regarding software – Respiro is physical modeling and built for wind controllers, probably the only softsynth today that works out of the box for this type of instrument. You can change and control the sounds to a certain degree but it tends to imitate real world instruments, which is the whole purpose of physical modeling. I use Respiro and I like u-he Zebra for it's wonderful warm blowlike sounds and UVI Falcon for it's endless sound and control capabilities. Both must be set up for a wind controller but this isn't too complicated.
If you consider to buy a Sylphyo, also consider the Sylphyo Link box. I am pretty sure that you will prefer wireless playing and for that you need the Link.
