Ok.
You confound MIDI tracks and Audio tracks.
I'm not using Reason 9.5 yet, but I'm a huge Cubase user. In Cubase, it's the same thing.
EZD used as VST in Cubase involve you can trig it from ONE lonly MIDI track, AND in the same time, having many AUDIO tracks to mix all in the audio mixer of Cubase.
But, you have to switch the EZD mixer to route each channel to a separate audio bus.
Please, remember, MIDI IS NOT AUDIO.
I can't tell you how to do it in Reason for now (I still in Reason 7 for some reasons ;)...), but in Cubase, You need to activate all audio out you need directly on the EZD VST interface. After that, Cubase create each audio channels in its mixer. Then, in EZD mixer, you just have to select each audio outs in bottom of each channel (between digit indicates faders values and channels names). You can rout each channel manually or select "Multichannel" choice.
I don't know if Reason is automatically create audio channels corresponding or if you have to create it manually.
Sorry if my english is not so good.
