I have a roland xv-88 and i love it. I have been trying to record the srx-02 piano board, which i also love. the only problem is that i record with the volume on the synth all the up and i think the synth itself is generating noise. i am going to explore a noise isolation filter for my ac source, but i really think it is the synth. is there anything i can do about this that anyone knows of? oh yeah, if anyone has any suggestions on power conditioners/noise isolation filters or better means for reducing any ac noise i'd appreciate that to. thanks.
