The ADSR is just an evelope which you are using to multiply the sound output with. However it is meant to be on a temporal axis together with the trigger of the sound. When I look at your patch I notice another thing: Why are you reloading the samples into the arrays every time you trigger them? The arrays should be filled on startup of the app, like this:
[loadbang] | [read -resize c1.wav c1Array( | [soundfiler]
Later, when you actually just want to play back, you do
[r c1] | [t b] | [tabplay~ c1Array] | [throw~]
and at one central point in your patch you can have
[catch~] | [dac~]
(add the main voulme there). Notice there are no connections between the three parts!
