HARDWARE DIFFERENCES

M3:
-- Custom sound chip based on HD-1 design
-- Radias chip (on EXB-Radias board)
-- 320x240 Color LCD Touchscreen (5 in. diagonal??) w/ XY mode
-- x amount of RAM to run OS and software
-- 256MB of compressed Sound ROM
-- 64MB of Sample RAM, expandable to 320MB
-- Control surface elements (keys, buttons, sliders -- no knobs)
-- audio inputs (2 analog [1/4"], S/PDIF)
-- audio outputs (6 analog [1/4"], S/PDIF, optional Firewire)
-- no internal hard drive
-- no internal CD burner

OASYS
-- generic (more powerful) PC processing chip
-- 10.4 in. diagonal Color LCD Touchscreen
-- 1GB (or 2GB) of RAM to run and hold everything
-- 628MB of uncompressed samples (effectively loaded as if ROM)
-- 200MB to 1.5GB Sample RAM (depending what Instruments are loaded)
-- Control surface elements (keys, buttons, sliders, knobs)
-- audio inputs (4 analog [2 XLR-1/4", 2 1/4"], S/PDIF) XLR Oasys audio inputs support 48V phantom power
-- audio outputs (10 analog [1/4"], S/PDIF, optional ADAT)
-- internal hard drive
-- internal CD burner

FEATURE DIFFERENCES
These hardware differences create some feature differences:
1. Instruments:
-- M3: 2
-- OASYS: 6
The M3 is fixed with the ESD sample synth and Radias synth engines. The OASYS is limited by only what Korg develops which currently includes the HD-1 Sample synth, AL-1 Analog Synth, CX-3 Modeled Organ, STR-1 Plucked String Model, LAC-1 Legacy MS-20 EX and Legacy PolySixEX.

2. Polyphony:
-- M3: 120 voices (fixed)
-- OASYS: 172 [HD-1][PolySixEX][CX-3], 96 [AL-1], 48 [STR-1][MS-20EX] (dynamically allocated)

3. User Interface:
Given its larger screen, for similar functionality, there are less numbers of screens to navigate in the OASYS when compared to the M3. Some of this is compensated for with the M3's PC/Mac editor (cool). The M3 does have the new XY mode (also cool), but the OASYS supports similar X-Y control via its Vector Joystick (though not as cool).

4. Sampling:
-- M3: 320 MB
-- OASYS: 1GB (all instruments loaded) to 1.5 GB (no EXs instruments)

5. Audio Track Recording:
-- M3: none
-- OASYS: 16 audio tracks

6. Simultaneous Effects Processing:
-- M3: 5 insert, 2 Master, 1 Total
-- OASYS: 12 insert, 2 Master, 2 Total

7. Audio Routing :
The OASYS has better audio routing capabilities

8. Karma:
Identical (with the exceptions due to the OASYS greater number of effects slots and more complex audio routing)

New M3 Features:
Having said all of the above, there are some new features on the M3 that are better than the current OASYS implementation:
-- Midi Sequencer: better resolution on the M3 and Cue List (OASYS owners are expecting similar enhancements to the OASYS sequencer)
-- PC/Mac Editor: Similar to the X-50/micro-X, this is definitely cool since the editor runs as a VST/AU/RTAS plugin


Bottom Line, I think the new M3 is a great replacement for the Triton Series since it leverages many things from the OASYS. Assuming the prices are somewhat similar to Triton prices, I can see a lot of people buying this (i.e. people who want a workstation).

[added by Dan Phillips:]

Except for the drum track, and perhaps a few other small details, the M3's Program structure is a subset of the OASYS HD-1, and it inherits many aspects of the HD-1's cool features and great sound quality.

The HD-1 still has a number of advantages, however, as befits the higher cost of the OASYS system. These include higher polyphony (172 vs. 120), faster envelopes and LFOs, larger ROM (more than twice the size of the M3, with EXs1), linear as opposed to compressed PCM, slightly better anti-aliasing, Wave Sequencing, per-voice Vector Envelope, etc.

The OASYS has 185 effects: 12 insert effects, 2 master effects, and 2 total effects;
The M3 has 170 effects: 5 insert effects, 2 master effects, and 1 total effect.

The OASYS signal path is 32-bit floating point, for extended dynamic range and less worrying about gain structure and clipping; the M3 uses a traditional 24-bit signal path.

The OASYS has a more robust control surface, with 8 knobs, 9 sliders and 16 buttons, and LED indicators for the sliders and knobs. The M3 has the touch-screen controller, but the OASYS has a physical joystick.

The OASYS has 4 analog inputs (including two XLR mic inputs) and 10 analog outputs, compared to 2 ins and 6 outs on the M3. The M3 has the EXB-FW for 6 digital outputs via firewire; the OASYS has the EXB-DI for 8 digital outputs via ADAT.

The OASYS has the 172-voice CX-3 and PolysixEX, 96-voice AL-1, 48-voice STR-1 and MS-20EX, and any other EXi that come in the future; the M3 has the 24-voice RADIAS-EXB.

I'd like to know by you Stephen, who had the luck to test both machines, what is the real difference in performances between the two machines in the sample editing area. The difference between Oasys and Triton family was quite impressive, especially on large samples, both in editing time and in display time of the wave graph.
Has the M3 chipset been improved respect to Triton one?
Thanks in advance!
Dave

To be honest, I'm not the guy to ask. I never did much sampling with the Triton Family, so I don't really have a range of experience to reference.

The M3's sampling pages pretty much resemble the OASYS, which pretty much resembles a large color version of the Triton. It seems to have some of the new features from the OASY pages, but other than that, looks all very similar.

I've got to assume that the updating and display is much faster - the processor is much faster than the Triton's, although not as fast as the O's, obviously.

do you plan on giving the Oasys owners a VST plugin comparable to the M3s? Sequencing editor?

Well, that wouldn't be up to me, I'm Karma-Lab, not Korg - but I have to admit that I find it unlikely that there will be that option for the OASYS. But I could be wrong. I haven't heard anything about one, though.

Are the 88-key actions the same are they graded hammer type ?
Will the new M3 Combis work on the Oasys are they available ?
Will a new future Karma 3 work on the next generation or will we need new hardware
Thanks for your work S

- The 88 key action of the M3 is new, but very similar to the OASYS.
- M3 Combis do not work on the OASYS, nor do OASYS combis work on the M3. Not without some conversion, which no one has written yet.
- A future KARMA 3 (whatever that is, since I haven't mentioned it really), would theoretically work without new hardware, depending on the features.

Hope that helps.

May I say "M3 is the second KORG' best keyboard"?
