I'm looking for a 49 key, keyboard with pitch and mod wheel to use with my acid pro 8 program. I want to be able to inport audio files from my computer, like mp3 or wav, into the this keyboard and add effects to them like pitch or mod wheel bends, or other effects on the keyboard, then record them back into my acid pro 8. Also for recording an audio file in different notes. I was told I needed a hardware sampler/workstation, but I'm not sure if any would have a pitch or mod wheel. Anyone know what I should get?
