John Foxx's metamatic was only done with a Roland CR78, but if you listen to the album, a CR78 sure doesn't sound like that all on it's own! They had to be devious in the FX they put on (a lot of flanging, ussually)
MXR Flanger-Doubler, on Metamatic, I think. I read an interview about the recording of that album and he said there were about 500 (IIRC) different patches written down for it, for the ARP Odyssey. I believe he still has the patch sheets... it's a great album, a wonderful example of what can be done with attention to detail and not much gear - as is S&S.
