I have just obtained a Roland JV2080 which I use with keyboard and Sonar 4. I am finding my way around the great features of this synth but I am seeking a bit of guidance. Notes using the patch "Cathedral" (which I have copied into the User Bank) seem to cut off too abruptly. I want to make changes so that notes die away gradually (sustain?) with some reverb as you might get in a large building. I would be grateful for any advice on how to begin.
