I just found an article on Ethernet connection for the Motif XF, so, I will follow those instruction and see if I can come up with a different result, thanks for any response anyway.

Can anyone tell me what I'm doing wrong? Actually, I have a five port Ethernet Hub connect between the Motif and my Imac, with ethernet cables.

You are probably not doing anything wrong except perhaps attempting something that was fresh more than 9 years ago. There was a time when this worked and you would receive messages via the Internet directly to your Motif XF keyboard screen!

Frankly, because it worked on a Windows protocol (SMB -“samba”) which would work for a while until Apple would change some basic kernel and it would break communication (I think they hated that bit of Windows code that was used).... the Log in function to address the computer more often prevented XF owners from logging into their own computers. The sharing and interconnection of XF users via the Internet and direct computer communication was perhaps ‘ahead of its time’... short-story: it didn’t catch on and was far more trouble to get going versus the benefit... you could read/write files direct to your computer eliminating the USB stick. In theory, you could setup a network of password protected computers where you could collaborate on a project... across the Internet. One musician could make a file available to others after adding their Overdub...

Soundmondo (current products like reface, MONTAGE, MODX) can be seen as a fast forward of the concept, utilizing a standard USB connection and a Chrome browser instead of Ethernet, Routers, WiFi etc. Connectivity is smoother (although not bulletproof), and it does allow “sound sharing”... we continue to find a “sweet spot” — one that is easy enough and practical enough for the majority of synth-users to use without obtaining a degree in computer connectivity. The whodo voodoo involved in setting up the Ethernet Connection did not appeal to the average musician.

I think the last internet notification went out over the Ethernet system was four years ago when the Synth Book and AN2015 were announced. Or at least that’s the last time I received a notification via that system.

The other day I was talking to a group of sales people and the conversation got around to connecting customer keyboards to the Internet, where the customer could visit a secure website, where they could audition song and sound content via this connection. They could download that data to a special Edit Buffer where they could try out the content on their instrument. If they approved they could purchase the content via their own secure account and it would be downloaded directly to their instrument... right there and then. The keyboard could be logged in as a WiFi device and be in the family room, it would address the internet via the home’s router... all done on a secure network.

The first question I got was “When is this coming out?” Sadly the answer is it came out in 2004... we introduced this fifteen years ago on the PSR1500/3000 (IDC)...

Sometimes these things do not catch on without a serious demand in the marketplace. But the hardware must precede it for anyone to know they want to do it. Yamaha is one of those companies that is willing to be out there on that cutting edge... not all things succeed (like FM synthesis did) but the company does like to push the envelope in Music technology. Certain technologies exist but due to a lack of a large enough audience they become overlooked and/or under-utilized. In most music stores back then (and sadly even today) computer connectivity is only whisper... there is no formal area of the store dedicated to use of the computer (not like you’d think there might be since computers have been an integral part of making music for more than 30 years...)

Thank you for your response, because as I went through the instruction, I got a "Can't Access the Host", so now I got some clarity on why it's not working.
