Hi all,

I am working on a simple java program to convert Microkorg XL patches to Korg M3+exb-radias... I came quite far allready, but still have about 15% of the parameters to figure out, and the vocoder paramters...

I am loading the Mkxl_all files and converting to an M3(+radias) .PCG file.

Also working on radias to M3+exb and R3 to exb-radias (both at 60% right now)..

My question:

Does anyone have the FULL midi implementation chart of the Microkorg XL???

And, can someone post me some banks (mkxl_all, RDL or R3L) (or email) so I could do some further testing in converting them??


Been working with the implementation chart of the older "normal" microkorg, but these are not fully compatible so I had to figure everything out by myself.

Thanks in advance!

Wish I could help, but good luck with this project, i'd be very interested in having them.

This is for the original Microkorg so it may not be of any use to you but here's the link.

This conversion, if possible, would be AWESOME

Hello pkeijzer,

If you have the document for the XL already, I would be interested to have it. I also only have the original microKorg.

I don't have a microKorg so I'm afraid I cannot help testing, but wish you all the best with the project.

Cool stuff. I already converted some patches from XL->m3 manually, using the two editors side by side This works absolutely, and the sound will be exactly the same.

Sometimes only the naming differs, but sure you figured this out already

Some differences:
- M3 has no random LFO curve. This can be emulated a bit by using S&H curve + curve shape +63 or something(?)

- Oscillator Pulse -> Oscillator Square

- Waveshape/Drive is simplified into one parameter in the XL. But theM3 can do exactly the same types of ws/drive types.

- At the LFOs, the key sync name differs (xl->m3):
Timbre->1st Note
Voice->Each Note

- The ENV curves of the XL are always linear.

- the portamento curve seems to be always linear on the XL

- PUNCH level is in the amp/eq section in the M3

- Sine/VPM Oscillator mode is buggy on M3, works only in program mode. So don't wonder if it sounds different.

- Virtual Patch destination naming:
OSC1 Tune -> OSC1 Pitch
OSC2 Tune -> OSC2 Pitch
Filter 1 Balance -> Filter A Type
Filter 1 Cutoff -> Filter A Freq
Filter 2 Cutoff -> Filter B Freq
Panpot->Pan

Also the order of the destinations are identically, so binary the representing numbers seem to be the same.


The old microkorg has a completely different synthesis. So I don't believe any data from it would be helpful at all.



Please keep the work up! Thanks!

Michel,

It takes a lot of time.. I am sort of finished with the radias (effects reprogramming is "no fun", and the M3 lacks step sequencer and arpeggiator (I thought about reprogramming Karma, but they're so different)..

I spent most of my spare time on this, and I seem to be hopping between the 3 synths (radias, R3 and microkorg XL), and replacing bits of code between the 3 modules (in the program).

I will post when I am confident at least from all the synths the "basic" sound parameters are copied correctly. At this moment I will have to find a way to have the M3 "understand" the .PCG file I create.... the M3 editor is not that picky and accepts what I feed it...

Regards,

Patrick

Mod sequencer is available on both, so these parameters will be copied 1:1 (referring to the radias, that is)
