I'm very happy with the Zadar. It's basically a list of digital envelopes that you can chose from. Some of them look very ADSR-like, though the module doesn't support sustain with a gate or something like that. Instead, you get a huge variety of non-ADSR shaped envelopes. You can use CV to change duration, voltage (= attenuation) and many other skewing parameters. The only thing I’m missing is the Nin expander, so I could have 2 cvs per channel. Anyway. Short summary: 4 super flexible channels in 10 hp. I love it!
