You can't blame everything on the Government. I just went to a Korg seminar and the guy there said that they hope to have it out by the end of the year. Having many of the sounds of the T1 come out early on the M1 ROM expander would steal the T1's thunder. There were some killer sounds on the T3 he demonstated, but nothing that will make anyone want to get rid of his M1. No word yet on price.
Standard disclaimers apply.
A couple of weeks ago, somebody posted an article about it. The guy Yo. The guy at Korg estimated I'd see it within about a month. Oh, the ROM expansion will have noise waveforms. I've been playing with my Steinberg M1 editor which doesn't take the new update into account, but it doesn't effect if much, it treats it as a card, which means it cannot access that memory and change the patches.
