MIDI keyboard volume baffler!

I've got an old Juno-106 MIDI synthesizer that I use only as a MIDI keyboard controller. The keyboard action is very good (Roland) and great to play. The problem: Lately, when I use it as a controller with Cakewalk MC 2003 and SoundBlaster Live the volume of whatever I play using this Juno-106 only as a keyboard controller comes out at half the volume of everything else!! This should not happen, of course, because MIDI is just data, not music "volume." I've checked all over this keyboard, I've fooled with all the switches. Nothing seems to fix this problem. I unplug the MIDI cable from this old keyboard and plug it straightaway into another MIDI keyboard and NO PROBLEM. It just seems as though Cakewalk and my equiptment hate the old keyboard and protest by making everything played on it half volume. Any of you MIDI whizzes out there have any ideas/suggestions?

Thanks, 57 Gregy. My Juno-106 synth is a 1980's, comparatively old, synth and from what I'm told, one of the earliest synths to even have MIDI. It is not velocity sensitive. At your suggestion, I checked the "event list" and saw the volume level is uniformly "64" for all keys. There does not appear to be any way to increase this within the synthesizer. Trying to increase its MIDI volume code inside of Cakewalk or in my Windows Volume Control causes all kinds of problems. Namely, when I try to "turn up the volume" everything else goes up commensurately and I risk blowing out my other equipment. I just replaced it with an M-audio Radium 61 keyboard controller which --so far-- I like very much. Still, I wish there was some way to somehow "up" the MIDI volume control of 64 to more up around 100 and continue to use that old synthesizer as a MIDI keyboard controller because it had great action and was such a pleasure to play. Oh well.
