Midi note is played when key is released

Hello,
I am using a Roland JX-1 connected with a HosaTech USM-422 midi->USB cable to a PC running Windows 7 Pro (x64). When I play one note at a time "Note On" and "Note Off" is sent correctly. If I press two notes simultaneously "Note On" is sent correctly for both notes. But when I release the keys simultaneously "Note Off" is sent for one of the notes and "Note On" is sent for the other (see Input Monitor image below).
I am grateful for any suggestions on how to resolve this problem because I am clueless

one possible solution use data mapping clone the note off and map it for any other note that could potentially be on at the same time

Thanks for the prompt reply 4x4UK,
I guess that you mean with midi-ox data mapper like in the following picture.
I don't understand this very well. Can you help me to understand what settings I should use?

Hi 4x4uk,
Thanks again for your help. The midi-map did not change the behavior for me.
You can see the behavior in the midiox input monitor screen capture below.
- First, I press a single note 'C' on the keyboard. A 'Note On' event is triggered. Next, I release the key and the 'Note Off event is triggered.
- Next, I press two keys simultaneously 'C' and 'E'. The pair of 'Note On' events are triggered.
- Finally, I release both keys. A 'Note Off' event is triggered for the note 'C'. But, instead of 'Note Off', a second 'Note On' is triggered for 'E'. The note continues to sound until I strike the 'E' key again in order to trigger a 'Note On' and 'Note Off' for that note.
Going completely off topic, I am guessing that your handle is due to a vehicle that you own. What kind of 4x4 are you driving there. I have had Jeeps in my garage since 1985. They have been very reliable vehicles for where I live in Michigan.

yes it is Day to day transport is a 3.6l TDv8 rangerover vogue
but my pride and joy is the defender 90 I built from scratch with 300tdi engine full roll cage and modified extreme suspension
with regards to the mapping you have to make sure its enabled.
What I posted above should send cc123 which is all onotes off when any note off message is received.
Ah the us manufacture plant for the company I work for is in pleasant prairie

Hi 4x4uk,
I made sure that the map was enabled. Still no effect.
I inserted a second line into the translation map. The map now looks like the picture below.
The result is shown in the picture below. Notice that there are 3 'Note Off' recorded in the output monitor which correspond to the 3 'Note On' events in the input monitor. The 3rd 'Note On' shown in the input monitor should really be a 'Note Off' because that is when I released the key

Changing the Min & Max Amounts from -1 to 0 had no effect.

in the first data map click the passon clone for the not off
then create another map that maps note off the cc123
Been doing a bit of looking around and a lot of it seems to be a windows software issue some people seemed to fix their problems by sending all notes off message twice
also if you dont need it try turning off active sensing

I am not sure what you wanted me to do. I am not very fluent in midi-ox yet. But I am learning 
Did you mean like this:
or
or did I get it completely wrong?
Both of these still had no effect.

As the JX-1 into the USM-422 is producing this error as seen in the input monitor there is a bug either on your JX-1 or the USM driver or the cables.
Check your Midi cables first. Although unlikely, I have had some weird problems with damaged Midi cables before.
Disconnect all Midi cables. Try one cable from the JX-1 out to the USM In. If there is an error in MidiOx, try the other one in the same connection.
If the bug is in both cables try connecting the JX-1 Midi In to the JX-1 Midi Out. This will cause 2 sounds to be played and sound like a slight chorus effect.
If a note 'hangs' when you do your two note test then the keyboard is the problem. Do a factory reset to see if that fixes it.
If its not the JX-1 it could be the USM. Try uninstalling the driver and reinstalling it. Are you using a Win7 x64 driver?
All the best

Thanks Breath,
That sounds like a good debug procedure.
The USM-422 is a MIDI to USB cable made by HosaTech called a TrackLink. The cable comes with very little documentation but the manufacturer says that it needs no driver. Older models of the cable did require a driver.
I have used the JX-1 synthesizer successfully on an older PC with WinXP operating system without problems. I installed Soundblaster Audigy on that PC. The card came with a panel which allowed me to connect midi to midi cable directly to the sound card.
I am now trying to connect the Roland JX-1 synthesizer to a new PC. Unfortunately, technology has changed and the Soundblaster Audigy will not work on the new PC - drivers fail.
Bottom line is that I suspect either the USM-422 cable or the newer Win7 Pro operating system. But I will not point fingers until I have some proof.
It is getting late now in this part of the world and I will try your suggestions in the morning and post my findings then.
Best Wishes,
DaveS

Hi Breath,
I found that the USM cable which is labeled 'in' must be plugged into the JX-1 synthesizer out. That is the minimum connection required to produce sound. I don't know how to test anything else beyond that.
One thing that has seems odd to me is the led indicators on the USM-422 cable. There are 3 led's:
- On the left is one labeled 'midi' which flashes blue
- In center is one that is not labeled and does not light up
- On the right is one labeled 'usb' which lights up red.
I have sent an email to Hosa Tech support asking if the led's are indicating normal operation. I don't expect to hear back from them for a few days. I will let you know their response.

Hi 4x4uk,
Thanks for researching that. It is kind of you to spend so much time to help.
That driver is for an older model of the USM-422 and would not work on my machine because it does not support 64bit. From the HosaTech site: Quote:
Please see http://www.midiox.com/cgi-bin/yabb/YaBB.pl?board=query;action=post;num=1 363900164;title=Post+reply;start= for additional information.
They probably should have come up with a different model number for the new one
I have sent an email to HosaTech support to ask them to clarify which LED's should be illuminated when the device is working properly. I hope to hear back from them in about 4-5 days. I will post their response.

I exchanged the midi to usb cable for a new one. Hoping that there was some problem with the original cable. This did not solve the problem and I am reasonably certain that the cable is functioning correctly.
I am ready to throw in the towel.
Fortunately, the JX-1 synthesizer has a pretty good set of sounds on its own. My workaround will be to use the JX-1 audio out. And, I will only use midi with soft synths for single notes.

So it looks like it is your JX-1.
Save your internal sounds etc before you do a reset to the factory settings.
ROLAND JX-1 HOLD WRITE AND FLUTE THEN POWER ON.
This is from http://www.dlse.nl/synthrepair/reset.html
I think this should read WHILE HOLDING WRITE AND FLUTE TURN THE POWER ON.
Test the JX-1 again.
If it is still a problem, borrow a Midi cable. Not a Midi interface, but a cable with a Midi plug at both ends and connect the Midi In to the Midi Out on the JX1.
If some notes fail to turn off then you have a faulty JX1 and need to take it to a tech to fix.

Hi Royce (Breath),
Thanks for your help. I performed the factory reset. The reset procedure you described is correct. I confirmed it in the JX-1 manual.
Also, I tried the midi-in to midi-out test. Everything works correctly.
I guess that makes Windows 7 Pro (64bit) the most likely suspect. I have no idea what to do with that.
I sent an email Roland support yesterday. I described the problem and provided a link to this forum so that they would have all information that I have tried to resolve the problem. The US support replied that they had not heard of the problem and they do not have a JX-1 to test. They forwarded my email to Japan to see if they have any information.
Sometimes I wish that God had not made me so stubborn. I said earlier that I was ready to throw in the towel. But I can not seem to get it off my mind
