Hi everyone! I'm a new to this forum, I'm from México City and starting a home recording studio. The first thing you should know is that I currently own a M-Audio Fast Track USB interface, and I'm planning to upgrade ASAP to a M-Audio Profire 2626. but in the meantime I have a terrible issue with a Korg Kaossilator. First I did this: Kaossilator RCA Output L -> Rca to 1/4 mono plug -> Input 2 on FastTrack Kaossilator RCA Output R -> RCA to Male XLR -> Input 1 on FastTrack Then: Kaossilator headphones -> 3.5mm stereo cable -> XLR male -> Input 1 on FastTrack Then: Kaossilator RCA Output L -> Rca to 1/4 mono plug -> Ch 1 on an Peavey analog mixer (panned to left) > Mixer output -> FastTrack Kaossilator RCA Output R -> Rca to 1/4 mono plug -> Ch 2 on an Peavey analog mixer (panned to right) > Mixer output -> FastTrack All resulting in a terrible Kaossilator sound, when I put the headphones from de Kaossilator, The beat was deep and punchy, but in the iMac was awful, punchless, distorted. When I used the Mixer, and the headphones on the mixer, the sound was good too, but not in the DAW again. I thing, maybe the Kaossilator output is way to powerfull for my small fast track maybe? I need to get an stereo input, because there are a lot of sounds in the Kaossilator tah travel from left to right and viceversa. The I plugged a Korg Synth (cant remember the model), with left and right outputs, with a 1/4 mono cable to input 1 on Fast track and a converter to male XLR to channel 1 on the Fast track, The sound in the DAW was awesome!! So, I'm kind of lost here. I'm using Logic Pro 9. Sorry for my english! Thanks a lot!!
