I don't like the Pyramid for what I needed a sequencer to do. I like long, song-length sequences that I can arrange ahead of time (basically a DAW but for MIDI only, and in a dedicated box instead of a distraction machine with a mouse and keyboard). The Pyramid has an awesome interface and great capabilities for live performance, but it lacks some basic features I need for linear composition... namely, it doesn't display which freaking bar of the sequence I'm on unless I go into a sub-window, and even then sometimes I have to toggle back and forth to see it.
Also, the Pyramid does not want all its tracks to be equivalent. In a DAW-like environment, all of the tracks can be followed simultaneously by the cursor position, and I can jump from track to track while staying in the same place relative to the whole song. In the Pyramid, you have to specify for each track, one at a time, how many bars the sequence will be. It assumes that you want polyrhythms, wheels within wheels. When I switch from one track to the next, it takes me simply to wherever I left off the last time I was at that track, which may be completely elsewhere in the sequence--and again, I have no way of immediately seeing this because the bar number is not displayed. I've made many erroneous edits because of this!
I'm still at an impasse for the right non-DAW sequencer for my weird requirements: basically, I want a sequencer to do what a live performer with several extra arms and MIDI controllers would be able to do with my Octatrack as it is playing. I don't have enough limbs to adjust parameters on multiple tracks simultaneously, going in different directions, while muting and unmuting "AMP VOL" exactly in time with pattern changes so I don't cut off reverb and delay trails, and fading tracks in and out for smoother transitions. I've tried doing this with an MPC, but I didn't care for the interface. Pyramid, same problem. My next gamble is a blast from my own past I just snagged on eBay yesterday, the first MIDI sequencer I ever owned, the venerable Yamaha QY-70. Hopefully the third time's a charm.
I'll be putting my Pyramid up for sale in the gear forum shortly if anyone is interested!
