would be fun to morph instead of just switching...

That's why I love the Voxtex.

yeah vortex & DL4 are what made me wonder about it. i just use my DL4 as a looper since i've got a bunch of other delays but i do kinda miss the days when i used it as a delay just for that... even if an A/B expression wouldn't morph the way those two do it'd still be interesting to gradually change from one chain to another instead of just instant switch.

That Keymaster looks like a Swiss Army knife. There was one in B/S/T recently.
Somebody (Loop-Master?) should make a pedal switcher that allows you to crossfade between multiple loops (with only one loop active at a time). Ideally the fade should be adjustable (duration and curve).
Does the M13 do anything like that? That would be a nice feature.

could you use a panning wah type pedal to do this? or am i thinking about this differently?

You'd need to sum the signals to close the "loop" you create with the a stereo panner. Both would have to go into a mixer. And you'd need the ability to mix one of the signals out of phase, in case the two paths are out of phase with each other. I'm also fairly certain you'd need the mixer to be buffered so that the two loops don't load each other down. I think when it comes down to it the Keymaster is definitely the most convenient solution, and may even be the cheapest when you factor in all the other stuff. Although this is all speculation because I've never processed anything in parallel in my life, and at this stage have no intention to do so.
I thought Morley had a stereo mixer thinger, but I seem to have been making that up, according to Morley's website.
I'm mostly here to post a pic of 80s Sigourney.

yeah that would totally do what i'm thinking of, long as it doesn't filter as well - i didn't know of those, will have to dig...

i don't know of those either... feeling dumb today.

what i'm picturing doesn't need a mixer and doesn't need loops, would just take a Y cable if sending to one amp.
i've been wanting to watch the first two alien movies again.
