    fatar vmk "dead notes"

    Sign in to disable this ad
    I have a 1-year old VMK-188 from Studio Logic from Fatar. I have a dead note, the F below middle C. Is only dead when no upper adjacent note is pressed. Any ideas?

    Might be an open ground on that key...and when the other key is pressed then the key makes a full circut...Im just guessing but it sounds reasonable.

    there are no grounds to keys... so unlikely...

    ime... that's normally a torn/misaligned switch... search for the cleaning keyboards thread and read through... if your lucky cleaning may get it... but doubtful...

    re: vmk-188 dead key

    More info. The key is not totally dead. I have noticed that is responds normally if no other other notes between it and about middle C are being held down. It's like a screw is missing inside somewhere that should hold the switch/contact assembly fast.

    I will have to get into it. I will use the excellent posts and graphics I found elsewhere on this site to to the procedure.

    Please see my other recent post and questions about abandoning Gigastudio 3 and upgrading my system.

    Thanks!

    I'm one of the guys who posted pics of the Fatar keyboard in the post on that topic.

    How did you make out with your board? I agree it would be wise to open it and look for a damaged contact.

    Sorry to be delayed (music business).

    I will post results soon as I do the fix. Meanwhile I avoid THAT note! Probably will take WEEKs b4 I do it.

    Still Waiting

    I have Fatar rubber/plastic (?) key contacts on back order since January 2010 and am still waiting for delivery. Soon as I get them I will open up my Studiologic VMK-188+ and replace the lot of them and post pictures of the process here in this forum). My Vmk is about 18 months old and more and more notes now are starting to go bad, in terms of original (great!) touch. (I have played it approximately an average of 1.5 hours daily.) To give an idea of my usage rate: mostly I practice/play Chopin's works, also a little Liszt and Rachmaninoff.

    Oh, and for the past few weeks I have been running the East West Quantum Leap Bosendorfer 290 virtual instrument. I remember the first day I got it really going (took several days to get there) I probably played it for 6 to 8 hours straight. It sounded so beautifully. The next day I couldn't play because my fingers were so bruised. (Hey, I remember reading that Rubenstein, the Russian virtuoso that preceded Tschiakowski (sp?), in later life practiced 20 hours a day and could give 2 back-to-back 2-hour concerts (total 4 hours)! A master and a worker!)

    And back to the EWQL virtual instrument. Even though I love it and it's the best virt or real one I've had, I must say these EWQL guys should fix their piano. They own this certain Bosendorfer. Guys, it needs work. Your samples, your recordings are great but the piano itself needs voicing badly. For instance: B2. Terrible. That hammer has turned to STONE. Replace it. And that's not all. Much of the recorded samples give WAY too much noise at the highest dynamic levels. My guess is, ALL the hammers need either deep needling or replacement. Bosendorfers are _famous_ for lack of noise, just more volume as velocity goes up (but not your Bosendorfer: please re-voice and re-sample, all 19000+ samples (sorry)). Still, what you've got today is beautiful and worth the $500 (verses the $150,000 real thing).

    Cheers!

    Finally replaced contacts. Many Pix.

    I am sorry it took me so long but I finally did open up the vmk-188+ and replaced ALL the rubber

    contacts. I have several photos of the work progress and will show them in this series of posts.

    This did fix all the dead note and dying note problems.

    In a summary here is what I found about dead and bad velocity notes.

    All of them had some kind of icky clear goo spread on them. The worst note, F3 was completely

    dead, had the most goo. I do not think the goo is from degeneration of the plastic contact

    material and I didn't cause it. I suspect the goo was applied by a technician to accomplish

    regulation.

    Reason I think so is this: when I got it all back together, with ALL new contacts the 'regulation'

    of the keyboard was / is completely different and not in a good way. Suddenly the treble, from

    about C5 to G6, thereabouts, has become weakened. And the treble all the way above it is now OK or

    maybe somewhat accentuated. I will have to fix this. More later.

    The whole disassembly, fix, reassembly procedure took me about 8 hours. I'm no pro tech and I was

    taking photos and notes all along. The moral is, if you are going to do this replace ALL the

    contacts while you have it open. They are cheap.

    Other observations.

    When I opened it up I immediately noticed one of the two two-wire connectors, the black and white

    wires one at the A0 end of the keyboard, was disconnected. I made a point to re-connect it when I

    reassembled, but it disabled the vmk's operation totally. No lights at all. I opened it back up,

    disconnected that connector and was back in business. My Vmk runs ONLY from the USB connection.

    The other external power port never worked out of the box. So this black / white connector may

    have to do with the USB port somehow.

    OK First pix is of the VMK top opened. This is after I removed every screw that was in the

    external case. Some were unnecessary but it caused no problems.
