hey, I don't know if you are still looking for input on this, but I am using Pamelas in conjunction with a Pulsar and think its absolutely brilliant. It can send out a huge variety of random triggers, gates, sequences, envelopes, lfo's. I am sequencing the pulsar from an octatrack which I run through the mutant brain to also sequence two voices in the rack.
I don't use Pamelas that much for jamming but during production this has proven a mighty addition. Mainly due to HP efficiency, as there's not really anything Pamela does in terms of uniqueness. It also saves a lot of crocodile clips in order to do some modulation straight from pam's. I was also thinking of buying the expanders to send a clock from pams to pulsar without using a midi-splitter, but maybe much of that setup is just unneccesary.
