When Korg announced the M3 in January, it was described as the PCM side of the OASYS distilled into a chip and married to standard Korg workstation facilities such as sampling, sequencing and KARMA. To some extent this is true, but the M3 is not the OASYS's HD1 engine in an instrument costing under half the price of its predecessor. The M3 borrows or adapts many concepts from OASYS, and rather than reiterate those here, I would suggest that you take a look at our review of the OASYS in the November and December 2005 issues of SOS. The second of these also contains a digested explanation of KARMA.
The M3's effects structure is a more significantly abridged version of the OASYS's which offers 185 algorithms that you can insert into 12 insert effects, two master effects and two 'total' effects slots. The M3 has fewer algorithms (170) and just five insert effects, two master effects and one 'total' effect slot. This is not a trivial reduction, and if, like me, you found yourself running out of effects on the Tritons, you'll continue to do so on the M3.
With no internal drive, the M3 can't provide the all-in-one solution that the OASYS can. Furthermore, while mainstream workstations from elsewhere can host 512MB or even 1GB of sample RAM, the M3 — with just 64MB of RAM as standard (and a maximum of 320MB fully expanded with the proprietary EXB-M256 board) — doesn't quite deliver in this area. You can save audio as WAV files to external media such as memory sticks and USB drives, even editing the audio on the remote medium, but you can't stream it, so it's not the same as having a self-contained unit. Furthermore, the M3 retains the OASYS's choice of 48kHz operation, which means that you have to use analogue I/O or resample your audio as a 44.1kHz WAV file on an external USB device before you can burn an audio CD on yet another external USB device (a CD-R or CD-RW).
With regard to expansion, the M3 is very different from the OASYS and much closer to a Triton which, given its price point, is as it should be. Nonetheless, Korg's Stephen Kay has hinted that there will be OS updates in the future, and it seems sensible to assume that Korg have a mechanism for eliminating bugs and extending the M3's features in the future.
Regarding voicing updates, the literature refers to EX-USB-PCM libraries. A trawl through the manual reveals that these will be 'loaded' rather than 'installed', and a little further homework uncovered that they will be loaded into the sample RAM from USB memory sticks.
Without any information to the contrary, I suspect that the only place to install future hardware upgrades would be in the EXB-Radias slot, so if there is to be further development, it would be along the lines of the upgrade that marked the transition from the Trinity to the Trinity V3 (in which the MOSS-TRI board replaced the earlier Solo-TRI board).
