my number 1 feature request is velocity sensitive scrolling!
having to hit zoom 20 times just so that you can get a start or end point adjusted by a single digit is lame, and so is the shift + cursor keys how the Akai OS did it. i find myself just settling for end points that aren't exactly where i'd like them because i don't want the hassel. i don't know why they didn't implement that like they did with the 2000xl, it was seriously the easiest trimming. you never had to switch screens or even lift your hand from the data wheel. if you spun it slow, it moved a single digit, if you moved it a little faster, it would make larger jumps depending on how fast/smooth you spun.
why is it that in the trim screen all of the pads play the sound in "note off" mode? does anyone else want to be able to tap the pad and have the sound play it's duration rather than having to hold the pad down? you didn't have to hold the pad down in the 2000xl.
in the load/save screens, i'd like to have hitting a pad play what's actually on that pad and NOT audition the sound that's selected. if i want to audition a sound from disk, i'll hit the "play" soft key. i want to be able to compare the sound that i'm about to load to sounds that i already have in my program to make sure they sound good together. that's key when trying to find drums to fit your main sample.
also, they've gotta fix this mute problem. with the akai OS, when i had stop/mute set to immediate, if you mute a track, the notes still get played, it's only the sound that's muted. if you unmute the track, the sound will start playing even if it was muted when the sound should have been triggered. try this yourselves, set mute/stop to immediate and load up just a looped sample in your sequence. play your sequence and during the first loop, hit mute, and then unmute before it gets to the end of the sequence and you'll notice that the sound mutes, and then unmutes. now hit mute in the middle of the sequence, wait for it to loop back around and unmute it after the sample would have been triggered. no sound! you have to wait for the sound to be triggered again to hear it.
