If any one could give me....a hand or tip here. I have a ms2000,karma,triton synths. i normally use the triton as my midi device, because it's 88 key synth.Now i have the others(synths) all hooked up. But sometimes it will not detect all 88 keys on reason for the larger synths. Then sometimes it will. Any ideas why is does it sometimes? like i can still play off the midi(triton)....butthe keys(keys of triton) will not play,until middle of the triton...wierd. There a way to let reason know, how many keys im actually using,to not have to wait till..reason feels i have more keys to work with. lol Thanks guys......

You may use the MIDI Learn popup menu because it is the best way to know what reason is listening to. It can help you to find out which key or controller is being sent by your keyb.
If this doesn't solve your troubles it's also a good idea to run a MIDI analisys tool like (free) MIDIMon.
Good Luck!
