when I am performing with analog lab.. the sounds will sometimes "jump" to the next sound.. while I am playing??? it cra cra. and this happens while I'm performing... very frustrated with this.. also another issue is that when I connect a second "slave " keyboard to the analog lab .. one is connected to my lab keyboard 88 key and the other is patched through to an m-audio slave controller keyboard,, what's happening is that I don't have any controls working on the slave keyboard.. it's all controlled by the computer through the "part" section.. so I assume that this is "normal" ... but this is when It becomes very strange... while im playing both keyboards in a performance... the sounds start to "jump" to the next sound on the list.. and completely frustrates me during my live performance.. please help anyone.. how I can rectify this problem
