When I play my Selmer it works great with a Stork mpc - it works real easy too.
But with a Asymetric it is 'orrible, and harder work somehow (though not as extreme as example 2)
However, I just can't play my Reynolds 'C' with the Stork, it's such hard work. Not only can I hardly get above the stave - but, it is such hard work - sucking my lungs out it feels!. Whereas, pop in the Asymetric and away it goes. Better sound, and easier to play.
Anyone know why there are such differences in the difficulty of play of horns with different mpc's? Differences in tone I get, but differences in the ease of playing the horn I don't.
