Hard to advise without more detail and being there to watch and hear.
The most important question is: How long has it been since you have been back on the trumpet? It takes weeks (on average 6 weeks) to tone muscle to the point of getting a consistent response. Time playing may be a relevant issue.
--> It's been about a year now redeveloping the embouchure. I've taken lessons with a trumpet player locally. I've also taken lessions with Ethan Chilton on Tonebase.
Once the basic embouchure development is well underway, than yes, playing with others and listening and then hearing the changes you need to make would be of high value.
--> I agree. This is what I've been thinking may be the main problem. 40 years ago, I played 1,000's of hours with others. One year we had 426 gigs logged with performances 7 days a week. Then of course practicing for hours together every weekday. The ear just may need to be retrained.
Is the trumpet in need of repair? Have you had other experienced trumpet players play your trumpet and if so, is the intonation fine when others play? If so, we can likely exclude instrument contribution out of the discussion.
--> Trumpets and Flugel are all brand new. No problems there. I am educating myself on technical design of the mouthpeices and instruments. Being an I.T. professional for the last 30 years, I think of the entire "noise" organism as made of up 3 primary systems: Human, Mouthpiece, and Instrument. Each of these systems can be broken down into subsystems. For instance, the mouthpiece can be affected by diameter, rim/cup shape, material, throat, taper, length, mass, etc. I've got a micrometer, throat, and Warburton gap measuring tools. I'm taking a look at how much gap I have playing on a specific trumpet with different mouthpieces and how it affects slotting and tuning. So it's a work in progress.
