Caramby, Ahicox, Carsimm, thanks a lot for the ideas.
good question about 'exactly the same'. no, not exactly. different keyboards for one: we use kurzweil sp2x's, the big show uses roland, i dont know what. the big show uses a big multi midi interface, we used small boxes, now USB (with no difference in sound). the macs are different, the show uses iMacs, we use two different macbook pros, one two years old, one brand spankin new, top of the line.
But the Logic/Mainstage is the same, the samples are the same, the adjustments (eq, filters, expression, effects etc) are the same, i.e., none. it's certainly not monitoring, system eq, that sort of thing. it's really a difference in the sound of the piano sample itself, coming out of the computer. i can use earphones for example, and still there is this difference.
do you think that the keyboards, or interface keys/computer (usb, midi) can make a difference?
really i don't think it's anything after the computer, monitoring or system eq or so.
it's not compression either, i know that sound, it's much more a 'dullness' of the tone of the sample, as if filtered. but it's not filtered! -- that i can find anyway.
btw-- i am using the logic/garageband samples, and they all haver the same filtered sound, like the steinway/b-dorfer/yamaha ones, you know, you get a choice of club, hall, room, studio.
i have been fiddling with the samples. using eq, lots of high end, some mids adjustment, i can get a reasonable tone. so it's as if there is a sort of autofilter. but where???
jeez. it just can't be like this out of the box, it's so ugly. yet it must be something with our setup, because that other one is not like this.
i am going crazy, spent so much time trying to figure this one out.
thanks again all!
