Before upgrading to 3.1 I found a screen (in master or factory setup mode) that displayed the wheel voltage.
I have had trouble with tuning and that screen could be a major help. So number one, I need to find that again .. Anyone?
I believe my problem is because my pitch wheel voltage is off … I remember the “wheel voltage"screen displaying that my pitch wheel voltage was at something like " -3” or “-.3” and my mod wheel voltage (when turn all the way down) was at “0.00” .. What I am assuming is that when the pitch wheel is centered (default position) it’s voltage should read “0.00”.. So to keep my MMV in tune I have to use the fine tune and pitch it higher by just a hair…
I am not sure if there is a software approach to fixing my Pitch wheel Voltage (master Mode, fatory setup mode?) or if I physically tweeked my PW so that when it is centered it is off by 3%. In which case I assume the only way to fix the problem would be to open up the wheel chassis and re-center the wheel so that its voltage is correct…
You didn’t by any chance upgrade from a very early version of the os did you? (up from 1.5) If you did and didn’t follow the instructions (as per 2.1) correctly that will result in strange problems – pitch being one of them.
I don’t know what the voltage change adjustment is for (perhaps use with outside sources, eg, sending cv to a modular or some such?) I AM NOT SURE ON THIS! So if anyone knows, let us know. I’m getting a modular soon and this could come in handy.
TunedLow is correct. Page 16 of the V2.1 Update Instructions explains the procedure in detail. You only need a Phillips head and small flat head screwdriver to disassemble the Left Hand Controller and make the adjustment.
Should only take about five minutes to complete, and won’t void your warranty.
And the hidden page to find this wheel data is here:
press MASTER
scroll to item “Software Version - 5.1”
press ENTER
press CURSOR
And because the values are displayed in 8 bit data (0 to 255) you should set the pitch wheel, that is will just go from -1 to 0. This is more close to zero then somewhere around the point where +1 goes to 0. Again, this is anly true because the display won’t show all the 14 bit data the wheel sends.
You might also try to use a MIDI monitor to adjust the zero point without using the Voyagers hidden wheel’s data display.
The problem was going on before the upgrade.. I thought the upgrade would fix it (if it were a software issue) but since it is a hardware issue I have to open up the wheel section and do the screwdriver adjustment.. I 'm not sure what version I had before updating, but it is what ever the original Electric Blue MMV were sent out with (my EB is #11)…
I opened up the Wheel assembly and checked it out.. The “set” screw that holds the wheel to the pot’s shaft is actually a tiny Allen wrench, similar to the original Minimoog wheels… It looks as if the set screw is set so well, that it even dug into the shaft of the pot. I assume this was done to avoid the problem I’m facing, which is the wheel is physically off by about .5cm or less…
I do not want to attempt to do this for a few reasons.
I dont want to damage the set screw or pot in any way, which could result in a permanent “slipping” of the wheel..
to access the set screw I would have to bend the wheel up, which would result in a different displayed voltage on the magic “wheel voltage screen” I mentioned.. So i couldn’t re set the screw to the proper voltage if I have to bend it up… This is because the chassis directly centered under the wheel is in the way of being able to access the allen wrench set screw…
If I missed something please let me know.. Is this the wrong way to correct my problem ?
I was hoping that I could go to the wheel voltage screen, and press a magic code of buttons to then change the wheel voltage back to 0 via the
-/+ buttons.. But that would be to easy…
Actually greg, I just thought about another possibility which would make sense about needing a small flat head screwdriver… Do i adjust the pot from the top ? Is it a fancy type of shaft with an adjustment on top.. I didn’t experiment while I was in there, because Kevin Lightner taught me a good lesson about making a tech problem much worse by not knowing what you are doing… Thanks Kevin..
Maybe I should just send it back in for a factory tune up before too long.. I’ll just use the fine tune pot to adjust pitch until I can figure out what the right thing to do is..
If I missed something please let me know.. Is this the wrong way to correct my problem ?
You don’t have to adjust the pitch wheel physically!
There is a little trimmer pot described in the upgrade manual of OS 2.1.
You have to adjust the zero point by gently turning this trimmer till just reaches zero from the -1 direction. And only this.
The Phillips head screwdriver is needed to undo the left hand plate where the wheels are mounted on. And the small flat head screwdriver is needed to turn the little trimmer pot inside. It is mounted on the little PBC-board of a few electronic parts near the wheels.
If you are not experienced with this, please print out the manual and this thread and visit a eletric tech. Each and every radio and TV tech is able to help you. Or maybe you find a frinedly Voyager user next to your place. Meeting other Voyager freaks is always a nice opportunity for making musically friends and some patch sharing.
