After all this talk of funny noises coming from the MD I decided to see if I could hear what everyone means. I'm sad to say that I can too here these 'decay' noises. I did a bit of testing and noticed the following things:- -The noises seems to be dependent on pairs of outputs i.e. a sound on the main outs triggers the noise in the main outs(A + B) whereas a sound on out C triggers the noise on C + D and a sound on E triggers the noise of E + F. -The noise does not seem to pass between pairs of out i.e. a sound on out E does NOT trigger the noise on out A,B,C or D. -The noise bears some resemblance to the sound that has been triggered. This is especially obvious with sound that have more high frequency content eg snares. This indicates to me that the problem could be some kind of signal bleed through. -The volume and erm.. (hard to describe) shape of the noise is effected by the volume of the sound that has been triggered. -There are other small, seemingly unrelated, periodic noises present on the outputs. All of this seems to point to a hardware rather than software problem to me. Bear in mind that I am just a student and my opinion probably counts for nothing and may well be wrong. Would anyone with a better technical background (Shifty where are you!), like to lend their opinion? You can quite easily reproduce the noise by, for example, assigning a bass drum to out C and then listening with the volume up on out D. over and out jng[png]
