Restoring Korg M1

stephenuk · Post by **stephenuk** » Thu Apr 09, 2015 7:35 pm

My Korg M1 battery finally gave up the ghost so I replaced it. Now I need to restore the original patches. Is there a way I can load the sysex data into my korg kronos sequencer then dump via midi cable to my m1. I dont have a midi interface for my computer and most newer synths have usb but have midi ports. Or if i loaded it into cubase is there anyway it can be midi thru the kronos then midi out to the m1?

Thanks

I've used the MIDI port on a Korg Kontrol49, connected via USB to a PC, to send sysex files from the PC to a Wavestation, without any issues. Worked much better than an el cheapo USB to MIDI interface.

the sysex disk option is to load into the kronos only, not to an external synth is there anyway of getting the sysex into the sequencer then it can be sent to the m1?

If you don't have any other device with USB and midi besides the synts, as far as I can tell there is no other way other than a USB to midi interface to send sysex from your PC to the m1. And if you have a old and slow PC you can use for that job than the older and slower the better, because the M1 needs very slow data transfer speeds, in small packages. MidiOx is probably the best program to send the files. I had to fight a bit with my PC and my T3 (wich is the same as the M1) when I needed to send files. Works well now but I had to get that transfer speed right

I used midi ox and have it routed to the kronos usb midi in then from the kronos midi out to the m1 what i found odd with the m1 is that there does not seem to be an arm option to set it ready to recieve? I assume i just need to have the m1 in global mode? I also have an akai mpk49 controller keyboard connected via usb as well and tried connecting the m1 to the midi out on that as well. The midi controller does play the sounds on the m1 in sync but alas does not seem to transmit the sysex data via midi ox

Humm, my guess is, if the m1will be able to receive the sysex that way, the main problem is the speed of transmission and the size of the packets of data, remember the m1 is a 25+ year old synth, it receives data slowwwlyyy, and modern PC are ultra fast. You need to work out the right send/receive speeds on the midiox settings. I can check out the settings I have on mine for the T3 if you like.

*Edit: According to the m1 manual, if you are in global mode, and on tha "midi data dump" page (f7), you don't need to do anything on the m1 other than have memory protect off. Turn the Excl to Ena on the midi filtering page, although you don't need to in order to receive midi dumps according to the manual (a bit strange

)
My midi ox settings for the sysex buffers (both low level input and output):
Size:51200
Num:64
I think they work well enough when sending sysex directly to the T3. If you are sending through the kronos however it probably may depend on how fast it is sending those messages through midi out, if the ones of the midiox or those of the kronos seq.
Hope it helps in any way

I loaded the M1 sysex into Cubase and then just played it back via my audio/MIDI interface and MIDI patch bay to the M1. Worked 1st time! No problems!

I don't think the Kronos will pass MIDI from its USB port to the normal MIDI ports.

I'm interested to know how you control all of your other equipment from cubase without a PC MIDI interface?? I assume some of your equipment does not have USB MIDI ports? If you want to control the M1 from cubase you will need a MIDI interface anyway?

The kronos and the akai mpk49 acts like a midi interface when connected to the computer just like a usb midi cable as they both have physical dins in and out. The m1 syncs to cubase no problem with the akai controller because i choose the akai midi out which triggers the m1 connected to it as you can choose either to route midi via usb midi or midi din out on mpk49. I tried loading the sysex data in cubase and it was a pain as i had to go into the list editor etc to manually create a sysex event then it allows you to import it in the sysex editor however the data is not stretched over say 2 minutes worth of track its the equivelent of one note?? Does anyone have a midi file with the sysex data in it so i could just load that into my kronos or cubase? When the m1 is recieving sysex data does it givd you any indication on its display?

thanks guys managed to do it now in midi ox i set the low level output buffers to size 50 and num 500 delay at 60 its all restored now

I'll look thru my archives later to see if I have the m1 factory patches in mid file. Or if I have any converter to convert from syx to mid
As for the m1 display indicating anything when receiving sysex, as far as I remember yes, it gives you that information, but I don't remember exactly what it says. I haven't touched an actual m1 in over 10 years now, the T3 displays "receiving sysex" my guess is the m1 is roughly the same.

Red lots and lots of replies regarding restoring M1 factory sounds with midi-ox after battery replacement - to date I haven't found the right set of magic parameters. Tried several of the ones listed in the forums but to no avail, best I've been able to get is about 32 bytes through. Today's computers are a lot faster than many of these posts so I suspect I REALLY have to slow everything down, but not sure what the right combination is of buffer size, number and pauses. Can someone help me get this up and running again?

I haven't found MIDI-OX to always be the best choice.

Have you tried?...
