MIDImate USB interface

Sasha · December 28, 2007, 7:41am

I recently bought MIDImate - USB MIDI interface/cable for integration into controller I am planing to build. The interface is built into connector which makes it perfect for integration as it will take very little precious space of my controller.

I really like it but it`s not working very great always…

Sending/receiving MIDI go without any problems, but sending aplication from MIOS Studio sometimes don`t work. Sending presets to MB6582 from MIDI-ox never worked with it (tried it with 750ms delay and more). :-\

Is it the problem maybe exceptionally long cable it has. It must be at least 3m long :o For plain MIDI data it obviously is not too much but what about sysx?

I can cut it short and make new connector if it will make a difference. What do you think?

Sasha,

If it’s any help, I run cables that are about that long on a box or two (with MIOSStudio), but I guess there’s a million other factors like cable type,etc.

I’d try to eliminate driver/host issues first, if you can run it on a different machine or OS. I’ve got a MOTU box here that works fine on 98, but will corrupt SysEx streams using its “so called” 2K/XP driver.

Hope you get it working,

George

Hi Sasha,

SysEx issues may happen with some devices. There’s a blacklist on the wiki (well, list sounds a bit overdone for three entries ;D - but I’m sure there are more of those)

http://www.midibox.org/dokuwiki/midi_interface_blacklist

Best,

Michael

Wiki edited. Thanks for pointing me Michael.

So, shortening long cable wan`t help?

audiocommander · December 29, 2007, 6:03pm

hm, I would also tend to Jidis’ opinion: this sounds probably more like a driver issue or a chip bug (guess this cable has some kind of converter chip?!) :-\

I would test the device with another operating system; if it works on another OS, there might be an alternative driver available - if not, I’d suspect the chip.

But I’m no expert with electron behaviour in cables, just guessing

Best,

Michael

At the data rate of MIDI, it would have to be a really bad cable to mess up the signal in 3 metres. You could always put a 'scope on it for a look.

There is a really good set of pages about MIDI delay testing at:Hinton Instruments

His other pages have a lot of good stuff too.

The basic MIDI test plug is an essential.

Another link of interest: this time from a history of the BBC Radiophonic Workshop, (for those who have never heard of it, The Workshop was responsible for a lot of innovations in electronic music in the UK, not to mention the famous ‘Dr Who’ theme).

hi sasha

i own an older midi mate, that one with the little transparent box and the red silk screened pcb.It works ok also with sysex.

NOTE: you need the driver to send sysex, normal midi will work also without the driver, this for XP.

I am not sure if the chip inside is the same as yours but we could check it out if you pass me the driver, and see if it is the same as the one i ve used with my midi mate.

I can t imagine the guys at audiotrack making a new device which is poorer than the previous in the same line.

hi again

i went to ESI s web (no audiotrack ! same company though) and it says:

The MIDI cable is compatible with Windows XP and Mac OS X without the hassle of complicated driver installation

now just for sake of it, try to install driver:

http://download.esi-audio.com/?w=esi&p=16&g=4&l=en

and see if it recognizes the interface.You could also try the RomI/O drivers.

Sasha · January 3, 2008, 7:38am

Ill install the drivers, but didnt tried it before as it was recognized by XP and plain MIDI worked OK but worth trying. I cut the cable off the interface and will solder new USB plug on 10cm long cable as it will be connected to the USB hub inside of controller.

Mike, thanks for the links.

T.K · January 3, 2008, 9:45am

Sasha, could you please determine the vendor and product ID of your cable? (called VID and PID in device manager)

I would like to check, if the same driver is working with MBHP_USB_PIC

Best Regards, Thorsten.

Sasha · January 3, 2008, 11:20am

NP. I`ll check it when I back from work.

cimo · January 3, 2008, 1:10pm

hi

after i got a midimate, i bought a cheaper interface of the same kind from ebay, when i asked the vendor for the driver for XP he pointed me out to… the audiotrack (now esi) website.!! when i opened the little box with the chips all the chips were “sanded” on the top so that you couldn t read the chips names. no need for explanation eh?

the chip on the midimate is a TAS1020B

usb_device.product_id 4096 (0x1000)

usb.vendor_id 2706 (0xa92)

Ashiman · January 3, 2008, 2:51pm

TAS1020!!! wow . That can be a full fledged audio interface… surely mass produced then…

T.K · January 3, 2008, 3:01pm

VID and PID are not sufficient - the driver doesn’t find the device.

I need to know more details - they can be determined with USBview (a Microsoft utility) which can be downloaded from here http://www.ftdichip.com/Resources/Utilities/usbview.zip (and various other locations)

Important: enable Options->Config Descriptors and Options->Location IDs

Thereafter File->Refresh (or press F5)

Search the MIDI device in the USB tree, and post the content of the information window as in this example:

ok here it goes

T.K · January 3, 2008, 6:53pm

Thank you!

The device will be detected now by the installation software after I changed the product ID (so that it matches with the .inf file), but the driver fails, probably because the I’m using different endpoints. Therfore I need more informations (which are given by usbview - Sasha: if you find the time… :))

Cimo: under Linux you can request the complete descriptors the following way.

First type “lsusb” to display connected USB devices - example:

# lsusb
Bus 001 Device 003: ID 046d:c016 Logitech, Inc. M-UV69a Optical Wheel Mouse
Bus 001 Device 001: ID 0000:0000 
Bus 004 Device 001: ID 0000:0000 
Bus 003 Device 001: ID 0000:0000 
Bus 002 Device 002: ID 0a92:1001 EGO SYStems, Inc.
Bus 002 Device 001: ID 0000:0000 
[/code]


Thereafter request the descriptors of the "EGO SYStems" device the following way:
[code]  
# lsusb -v -d 0a92:  
Bus 002 Device 002: ID 0a92:1001 EGO SYStems, Inc.

Thorsten, here is the info you need. I expected Ill see the midimate on the list, but it appears as the "USB Composite Device"  ??? The first time I connected the interface to the computer XP recognized it is midimate and it initialized it properly so It is strange it is not appears as the midimate. Ill download and install the drivers and will check if there is any difference.

Just ask if there is anything else I can do.

Sasha FWIW I have two pairs of 10m cable and a pair of 12m cable running to the synths on the opposite sido ef my studio and they’re running next to audio and power and no problems… I think 3m should be fine
