Fostex vf 160ex odd things happening

Hi I own a fostex vf 160ex have had it from new a couple of years ago, been great so far but lately I have had sometrouble with the PLAY button , sometimes it doesn't work, & when I switch It off & on again it is ok for a while. Also I recently recorded a live band only to find back in the studio it plays slow! I can't work out why? It records ok in the studio, I know about the pitch shift & this was definately not on whilst recording, any ideas ? Mike Whiting

    I have solved the playing slow problem , I was using a behringer preamp
    which was set to 48hz the fostex was set to 44.1hz, fostex helped me
    with that one.

    However the button problem is getting worse I have seven buttons that
    are not functioning properly. They allow you into parameters but
    pressing "EXIT" or " STOP" or pressing the parameter button that got
    you in to the parameter in the first place does not allow me to exit!
    It is only when I press the "program select" button can I exit the
    parameters. Now the "PGM SEL" button will not let me select any
    other program other than the one I am currently in!

    I find it hard to beleive it is a problem with switches as fostex have
    suggested, as so many have gone wrong at the same time. I am more
    inclined to suspect the software or the hard drive, does anyone know
    where I can get software updates ( I have tried fostex & although
    helpfull I have not been able to obtain software. ANY ONE HAVING

    Aloha! My Fostex VF160ex outputs (including headphone jack) are crackling, distorting and the volume in greatly diminished. I don't think it's the hard drive because the information burns cleanly to a CD. Does anyone know about the AD or DA converters and if this is something we can repair ourselves or if we need to send the unit back to Fostex...sorry to bug you. We're in the middle of a project and I'm a little desperate.

    Thanks, Jen

Jen / Gently, I know you asked your question a long while ago, but I've got a solution. I had been having the same problem with mine for a while but I found an easy fix which worked for me. The outputs were acting weird, sometimes only the left channel would play, sometimes only the right, sometimes nothing. So I took mine apart, looking for a short. I couldn't find anything, so I tried my backup plan - spraying a can of computer duster (compressed air) around every nook and crany. I guess some grime inside was causing the short. Works as good as new now. I'd say first try spraying the duster with the case on, and see if that works, but you might have to take the case off. It's easy to remove.

If you do have to remove the case, here's some tips. Make sure you've had it unplugged for AT LEAST a minute before you go at it to make sure any residual charge is gone. You have to first remove the two black plastic side pieces, then the little metal piece by the cd tray. Then a bunch of screws on the sides, bottom-front, and back top. The wires aren't real long so you kind of have to fold it open. Just hold it open with one hand and carefully spray the duster around everywhere. Ussually duster will come with an extention straw and I recommend using it so the can's nozel doesn't get real close to the electronics (it can get kinda cold sometimes).

Well, I hope this helps you out.

I sprayed some electronics cleaner (old from Radio Shack) right onto the button, it seeped into the switch (was the REC TRC button) and it instantly began operating correctly. Made sure unit was off while I sprayed and cleaned up.

It is a button contact switch problem, common with Fostex VF machines. You will need to open up your VF and get to the contact switches underneath your top panel. You will need to blow out any dust and dirt first, second you need to take some Caig D100 dropper contact cleaner (you can find Caig products on Amazon and eBay for best prices) and try to get a few drops into each contact switch on the circuit board and work it in by pushing on the buttons rapidly with your finger to get the cleaning fluid inside the contact buttons. Then you should take some Caig F100 fader lube and put a few drops in the contact buttons the same way as described with the Caig D100 contact cleaner, first clean then lube. That should solve any button problems, if that does not work fully then you will need to un-solder and re-solder on some new button contacts. You can get these online at eBay and other electronic supply stores. Finally you should do the same to any potentiometers volume control knobs or pan controls that are acting up too, scratchy noise when you turn the knob, same cleaning and lubing procedure described above applies to all turn knobs and dials you have on this Fostex machine or any other piece of electronics gear you may have issues with..
Also and additional good tip is this: On your Fostex VF machine push and hold down the shift/stop and track 9 buttons together to get into the VF machine button test mode. You can then test all buttons to see if they are working or not and how well they are making contact y pushing down any button, make sure to test all buttons. To get out of this mode hold down shift/stop and master buttons to return to normal operation on your VF machine.
Hope this helps and sorry for being 5 years too late to answer.

I have the Fostex MR-8 mk II without the burner. I'm having trouble as of late at exporting my finished song to a laptop computer. It's worked fine in the past. Could it be my USB cord is bad? The computer...

USB cords are cheap and can often be found even in Thrift stores... try a new one to eliminate that possibility... I will say they RARELY go bad unless they have been abused.

Remember that reading a USB stick by the computer is FAR different than transfering data from the Fostex...

MAKE SURE the driver for the Fostex in your computer is intact...

OFTEN the stupid DLL files that were working get CLOBBERED by new software and suddenly old things that used to work don't anymore... Thank MS for the stupid thing of allowing new software to change DLL's.

Hard drive failure

First thing is to open the unit and make sure the drive is connected. Sometimes cables get knocked off.

Next get a new drive... they are relatively inexpensive, like $69 or so and try it.

Take the old drive in your hand and snap your wrist to impart a spin to it. Then try the drive again... If it comes back to life, SAVE ALL THE DATA from it quick, and transfer to the new drive.
