Hi Serge, i think we are totally different players. Nothing is wrong with that. We share the age.
I am from a jazz background, an modern music. I am a big Coltrane fan, i am more into shaping the tone, lIke Archie Shepp's later years, Chat Baker maybe , slow Miles, Ella and Billy Holiday style.
I Married the WX windcontrollers with a Kurzweil K2000 to make my own tones or sounds. Later joined with a Physical modelling synth, the Yamaha VL70m. There one could make similar sounds ike the mistakes one makes on an acoustic instruments, like overblowing.
The WX controllerswere rather primitive: Breath, pitch in the good way, with the mouth , and a modulation wheel.
The WX es were rather breakable, so i added a EWI 4000. I found that a total desaster`: with bite you add a vibrato from a LFO ? Pitch was two half wheels with the right thumb?
I could not do the things i do with the internal sound. Midi was not wireless. And on stage it is warm, one sweats: when th controls touch a sweaty shirt, it is out of control. I sold the 4000 immediately.
When my last WX broke down, i got an EWI 5000 hoping that this was a cure: least i had a windcontroller.
When i found out about the Sylphyo, i immediately ordered one. I think i have one of the first white ones, La Neige. It looks like a toy, not a golden flute, more like a baby drinking bottle. And it plays like a toy: so much fun to play! I blocked the air exit with a piece of tape, so i have the right amount of backpressure and a need less air to make a tone.
First strikes is the enormous dynamic range : from pppp to FFFFF, easy and natural. One can really whisper, And raise natural. Tongueing is like a recorder. Simple.
Helas no pitch reed, But it has alternatives. Up and down movement changes the pitch: I add vibrato like a cellist on the string. A natural way and in control.
an other way is via the fingers: Sylpyo allows half hole fingering, like on a flute or recorder. this allows pitch bend up, and down.
Top of the right hand slider window is also set to pitch bend. I have assigned it to something else ( sometimes a puff of breath noise)
One of the great things about the Sylphyo is the extremely versatile configuration options. all controllers can be assigned as you wish. Which means also tht you have to know what you are doing, and it can mean that one has to learn from scratch how to play.
Same for the fingering: you could choose EVI (three valve something) I started on Sax, than i wondered why should i use the ugly fork grips? I changed to EWI + left pinky, which allows me to play easy chromatically. Back to the exercise board, scales scales. It workes but sometimes my mind switches to sax. And that is messy.
I am marrying the Sylphyo to a ASM Hydrasynth Destop + Vl70m when i play computerless, with computer i use the Respiro and [Surge](lihttps://surge-synthesizer.github.io/nk url)
Hope i gave you some idea
I intend to add the Photon in a later stage.
