Hello All,
I still have a Korg i5M, two 140M's with harddrive and a Gem Genesys XP. Ive also use the Korg PA1X PRO and my PA60 as expanders with the midi accordion and as stand-alones. I've had the Roland RA-800 in the past and have used my friend's MS-40. I regularly inquire to Korg and Yamaha about offering an updated module (e.g., based on the T-2 or the PA series boards). As George pointed out, Yamaha's response is always, 'there is no market for an arranger module'. Korg's response is usually, 'There's no information about a module at present and we'll submit the idea for consideration.' My thought is that, after enough inquiries, they may actually consider producing a module.

Giovanni,
Still waiting to hear how you work with the midi accordion T-2 combo on gigs.

Ciao,
Jerry
