Do have it. It does very well if you need AD envelopes, and you can also individually gate each one. The inverters are always useful. I personally have it downstream from a clock (Hermod) that then goes into a sequencer (Popcorn) and I use two slopes for voices and the other two to modulate things at half the speed with the built in clock divider. You can also break the normalling of the LFO as the clock and manually step through the divisions as a per-step set of rising and falling LFOs like a Stages.
