Gear Junkies have a story that Alesis will be announcing the Ion-R rackmount Ion at MusicMesse, the big German trade show in April. It's a nice-looking, knob-covered synth, but it adds very little to the already ageing Ion. There are extra outputs and more presets, but still no proper onboard effects, and it doesn't seem to have the extra sequencer that's in the Micron. No price yet, but I think they're unlikely to charge much more than $500. UPDATE: Looks like this is, er, a hoax. Cleverer people than me have spotted that the box is totally the wrong shape for a rackmount...
