USB-MIDI (Korg M1)

Jamie , REALLY helpful so far - I'm almost at the end of the process -  but no end product yet and it's interesting to note the recent post below.
 
According to Korg support UK I am doing everything right, and the support guy had just come off the phone to someone with an identical problem.
 
I purchased an A03FK USB-MIDI Interface from Maplins, made by Mistar. There was no drivers CD with this.
 
The data transfer from Sysex appears to all happen, but the Korg has nothing. I have increased buffer size on the low input and output to 2048.
 
I have also done the checks on the Korg, CH=1, Memory protect =OFF and exclusive messages set to ENA (enable)
 
I understand from them it's something to do with the standard drivers from MS (Windows XP). - a note on the packaging for the cable says Windows VISTA compatible, I wonder if that now excludes XPHuh
 
Is there anyway I can get this USB device to pick up another internal MS driver (I am NOT an expert in this area at all) and would need handholding.
 
Does anyone know how to contact Mistar - I can't immediately find them on the internet
 
Any assistance very gratefully received!

Hi Martin, It's reassuring to find a recent post where someone else is struggling in the same way as me. I have got a mint condition M1, which has had the battery, replaced and needs a re-load. I’m running Windows Vista and spent hours researching the best way to do it. I eventually downloaded MIDI-OX 7. and spent time reading their instructions together with the ‘read me’ file from the Korg factory download files. I too have bought a USB to MIDI cable. Mine was an ebay purchase and was marketed under the name of ‘CAVO ADATTATORE’ however, it is made in China and similar to many other cables on the market. Mine has a bulb in the middle housing 3 LED lights, Red:USB, Amber:MIDI and Green in the middle next to an icon of a treble clef on some music score. It comes with its own drivers installed (no disc) and claims its compatible with all MACs and XP and Vista OS. When I plugged the cable in, the drivers installed themselves successfully. Apart from that there is no support and little in the way of instructions.
 
So armed with all this newfound knowledge and techno trickery I attempted to carry out the factory reload via the SysEx utility. Both my USB and green LEDs light up when attempting file transfers but not the MIDI light. Despite all attempts, I have been unsuccessful. I have tried all the checks you talked about, checking cables settings etc but I can’t install anything. At first the transfer stopped stating that the port was busy but altering the delay in the SysEx configure tab from 60 to 200 or greater allowed the complete file transfer to happen. However, nothing is received on the M1.
 
With regard to your cable, I have never heard of Mistar. It wouldn’t surprise me if it was a similar Chinese produced item. As for drivers, I’m stumped and left wondering if I have an issue in that department or if there are other settings I need to tweak! One thing is for sure, they don’t make it simple do they! I have read just about every help item and forum page on this subject and am nearly at the stage of throwing the whole lot out the window! Any suggestions from anyone would be most welcome.

I would guess that this MIDI device is using the Microsoft USB driver, which can be problematic.  Check this: http://www.midiox.com/cgi-bin/yabb/YaBB.pl?board=query;action=display;nu m=1206643557
 
In addition to increasing buffer sizes, also make sure that you have [x] Delay after F7 checked.  Try inserting delays in both spots -- 120 milliseconds is a good starting value.

Thanks for your prompt reply Jamie. Funnily enough, I had spotted your post regarding a Hardware Loopback test shortly after my initial post. This seems to me to be the first thing I should try and will do so when I next have a go at it. I do hope its not a driver issue as I think it will be an uphill task to stop the built in driver from installing it self every time the interface cable is connected!  
I will post again and let everyone know how I get on as I believe that this is the most common problem encountered by people such as me and Vista is not the most obliging operating system! Many thanks.

And I have the same problem!!  Aaarrghhh!!
 
It all seems so simple and then.....
 
My USB to MIDI interface is a LogiLink unit and I have tried everything I can think of.  I even found the 'You Tube' tutorial on how to...etc.  From that I did note the need to click on a 'driver' type line and came to the conclusion that I was missing something as there was no such line available on my 'window'.
 
I am sure it cannot be that difficult, so any nudge in the right direction would be soooooooo useful.  I really miss my M1 and have just changed the internal battery (as others have done) and can feel my creative juices ebbing away as i type...!
 
Many thanks

The solution is simple: replace the MIDI interface with one that works (e.g. Edirol UM-1ex in "advanced" mode -- quite why "advanced" is a synonym for "works properly", I don't know).

I'd like to think that I had acquired a working unit but I take your point - it has to be something in the mix.  Having trawled through most of the other comments found elsewhere on this site regarding the problem, it does seem that the M1 is/has been a bit of a swine in terms of Sys Ex issues!!  Still, having an M1 in the first place means one must have very patient demeanor!
 
Many thanks - I'll give it a go.

You need to start with a known working MIDI interface on the PC before being able to troubleshoot the rest of the end to end connection, unfortunately.  The M$ USB MIDI interface is a known troublespot, so it's the first place to hit.  The generic USB adaptors will not provide alternate drivers.  They're designed to the generic spec.
 
Best of luck.

Hi Peter & Jamie, your help has been very useful so far. I finally got around to doing a Loopback test to see if the interface is working correctly. By carrying out Jamie's instruction I have concluded that this cheap eBay Chinese special of a USB to Midi cable is probably at fault.  
 
I opened the SysEx View and Scratch pad window and moved it to the right so I could see the Monitor out put window as well. I loaded the M1 reload file and press Send/Receive SysEx from the command menu. The green activity light comes on the interface and then goes off when the file has been sent.  
 
In the small SysEx Receive window that pops up that says (wait for completion) above a ‘Bytes Received’ counter, I can only ever get the figure of 2. When you click ‘done’, there is only ever F0 and F7 (in red) in the bottom window and nothing in between. No amount of fiddling in the configuration settings will alter this outcome so I guess the cable is the problem.
 
I have discovered that the only way to bypass the built-in driver is to go into the Device Manager from the Control Panel and locate the USB port which is being used, then go into the properties and delete the driver. Then you can load one of your choosing, as long as it is in a .inf file format! I spent too many hours trying to find and replace the driver for this cheap interface but to no avail unless any one knows different?
 
I eventually gave up after several hours and now I’m seriously looking at trying the ‘Edirol um-1ex midi interface’ cable as recommended by Peter.
 
Any further help and comments would be welcome
 
Paul.

I got hold of an Edirol UM-1EX device at the end of last week.  As predicted by Peter, it worked a treat (once I had been through the rigmarole of loading the CD driver disc).  Also had another chat with Korg UK about the correct Sysex files to upload.
 
FYI - Digital Village - £29.00
 
Peter - once again, many thanks for the assistance.

Phil,
 
Thanks for that. I've managed to find one on eBay for £21 so hopefully this will do the trick and I'll report back with the result.  
 
Fingers crossed!!!
 
Many thanks,
 
Paul.

Success!!!  
After what seems like years of banging my head against the same brick wall, I have finally done it with the Edirol UM-1EX. The interface set to ‘Advanced Mode’ worked straight away on a loopback test after I had reset the buffers to something less extreme! With this device the buffer settings and delays seems less critical. Mine were set to 256 on the low level output and the delays in both fields were set at 60 MilliSeconds but I believe that other configurations will work as well.  
 
I tried playing around with the drivers on the old interface but got no where.
 
This reloading of the factory presets seems to be the most common problem with the M1 and this whole exercise just goes to show that with the right kit (which is known to work) the process becomes very simple. Having been through this journey I would like to thank all especially Peter who steered me down the Edirol UM-1EX route!
 
It there is anyone in the Midlands area of the UK who is stuck with the same problem I would be more than happy to help out with my newfound success! Feel free to get in touch.  
 
Thank you all.
 
Paul.

I have a pretty similar problem to the ones encountered here....
 
Just wondering though, when the transfers were failing did the patch names display correctly on the synth? or did nothing at all go through?

Matt,
 
Nothing gets transferred at all when I was using the cheap interface so nothing was being displayed on the synth. The secret really is to carry out the loopback test. This will tell you how much, if any, is getting through the interface. Also, if your buffer settings or delays need tweaking, you can do this before finally carrying out a transfer the M1. If you live within reach of Shropshire, I’ll do it for you in a jiffy or I’d recommend getting the Edirol UM-1EX.
 
Good luck.

Hey Paul, i'm just "next door" in the West Midlands i i wondered if you can rescue my M1!
 
I have replaced the battery, lost everything, and i can't get the sysex back on it!
 
I have tried a Soundblaster 16 with joystick to MIDI cable, i have purchased one of those cheap USB to MIDI cables which both work for MIDI playback. I have tried MIDI-OX and Bome Send SX on the pc, i have also tried SysEx Librarian on my iMac with the USB cable.
 
I have gone through countless walk-throughs for the Global settings on the M1 and still nothing.
 
I just wondered if i could come to you and see if you can make any sense of it and there'll be a few drinks in it for you. I'd like to say i'm tearing my hair out but there's not much there to pull on lol
 
Many thanks, Andy

I'm going to chime in here, as I have an M1 (since new in '94) and have been through the battery replacement exercise as well. The PC I had been using, running XP and with an M-Audio Audiophile 2496 card in it, recently died. Long story short, I'm now on a more powerful PC running Vista, and the M-Audio card didn't work so...
 
I bought an EMU USB-Midi adapter, and was trying to restore the original M1 samples for some personal studio work I'm doing. Digging around on the net I discovered a LOT of people having troubles, and a LOT of recommendations about how to configure SysEX buffers and timing to get things to work - None of which got me anywhere on my setup. The data on the M1 would always end up corrupt and disfunctional.  
 
Here's what I did, what I discovered, and how I succeeded:
 
- I used the SysEX window to do most all of the transfers and comparisons, as it gave me all the info I needed.
 
- In trying various buffer sizes and timing, I discovered that the data (sent back with the DUMP command) looked okay up to a certain point, EVERY TIME. That certain point varied depending on the timing I used; but it was clear to me that the interface was okay for the first ~100 bytes on every transfer, then there would be a block that was bad, then another 100 bytes or so of correct data, another corrupt block, etc.
 
- SO... I set the buffer sizes to 64 bytes (just to be safe), set the buffer delay to 1000mS, and gave it a go.  
 
It took about 15 minutes; but the transfer was successful.  Grin
 
I still ordered a better USB/Midi interface (the M-Audio box); but it can work.  
 
BTW: I did notice that no matter what I did, the DUMP file was only 16350 bytes. The whole send file was more than double that (with both the program and combi patches). Is this a setup issue in MidiOX?

My humble contribution for this issue:
 
I recently bought Korg M1 and wanted to reload the factory presets. I bought a cheap generic USB-Midi interface and watched this video  
 
https://www.youtube.com/watch?v=UOhXcI38Juw
 
carefully and followed all steps. Nothing happened. I tried with MIDIOX on PC and SysEx Librarian on Mac. I read all the forums over the internet regarding this and tried different buffer settings. That took considerable amount of time.
 
The solution was to use quality midi interface and cables. I borrowed a Focusrite Scarlett 2i4 and a Klotz Midi cable, plugged it in to a mac and all the SysEx files went in without any hassle, or tweaking with the buffers and stuff. Everything was done in 5 minutes. Probably it would also work with PC/MIDI-OX, or any other quality midi interface.
 
tl;dr - Do yourself a favour and go for good midi interface.

To all: One thing that I’ve learned with Windows is that assigning a drive letter is critical and Windows does this automatically. I’m on a server and geeze I have a lot of drives. Some of you might be experiencing this… When you plug in a USB or any external device, Windows assigns it a drive letter. BUT, Windows will only go so far. So the typical set up you’ll normally see would be A (Floppy), C (Hard Drive) D (CD/DVD) E (CD/DVD). Those are the standard. Now, take into consideration of partions or being on a server where you have access to drives on the server. Now you’re looking at more letters. If you plug something in to your machine now, Windows will get confused because it wants to give that new drive a letter but it’s already being used. So needless to say, all the info it there but you just can’t access it. Here is my cure. Right click on “My Computer”… in the pull down go to “Manage”. On the left hand side you’ll see a list of stuff. Go down to “Disk Management”. Now, if your system is working properly, you WILL see a list of ALL active and working device drives. iPod, jump drive, external HD, C drive, partions, etc… You will see whatever it is you’ve got plugged into the USB as long as it’s storage. Right click on that drive and click on “Change Drive Letter”. Now you’ll see a window in which you can pick the drive letter you want Windows to use when plugging your device in next time. Just click on “Change” then you get a scroll down of choices of every letter that hasn’t been used yet. I would say start close to the end like at Z. Let me know if this helps anybody.

My M1 battery got low, and I decided to change it, but forgot that all the factory installed sounds are deleted.  I did about 6 hours of research and trying everything, including changing the buffers in midi-ox, going thru the M1 setup about 20 times, etc. It appears that there are many different problems can show up, including hardware, drivers, sw setups, etc.  The last thing I figured was the file itself I was trying to load.  I searched for the factory default sounds for about an hour, and finally found one called "factory preload" which was in 4 separate syx files.  But they were wrong, because I couldn't get them to load properly.  The prog file would not acknowledge at all, but the other 3 would give a "completed" transfer, and this was totally confusing.  I finally decided to research another file set, and found a file called "M1factory.syx" and this file cured my ills.  I'm going to try to give some  Angry feedback on the files that don't work.

THIS WORKS!, Thanks tcwild, the transfer took 13 minutes but after spending two days of try this and that buffer setting, questioning is this really the original file for the M1 the very small buffer and long buffer delay works, BTW my hardware ; KORG M1REX (rack module,no keyboard with extended memory "EX") TASCAM US-144mkII midi interface MIDIOX on a Windows 7 computer.
