I can get the FP to work if::  (X1 and 8.5.3, 32 and 64 are the same)
    I open a project, add the FP

But, if the FP is already added most projects will not open
  Sonar hangs
    and the FP fader moves erratically

Saturday I learned of a new firmware, 1.3.8, and installed it. No problem with install.

Tested in X1, same result. 

Found a note that ALL midi things had to be disabled/uninstalled before the FP install. So I disabled the audio interface, and all virtual midi stuff. Installed the FP and tested in an empty project. OK.

Added the audio interface, virtual midi cables, and opened some of the sample projects. Got through about 3, and then same result. Tried a couple of my projects. No joy.

Thinking maybe the FP is broken, or something is weird about my hardware, I installed Studio1, and Reaper, and tested in empty and small sample projects. Mostly no problem. In Studio1 the fader would resist movement a bit. And in Reaper the buttons did not glow, but they did function. changing, saving, closing and opening: all good.

In the presonus forum there are complaints, and happinesses, for ALL kinds of hardware and software. Many complaints that the FP does not work with Studio1, does not work on the Mac, and so on.

It appears to me that Sonar is initializing the control surfaces before loading the project. If it did so as the last bit of loading it might fix my issue.


Could it be particular plugs, instruments,...

I have spent way too many hours over the past year attempting to sort it. Truely disappointing.

Exactly what I was seeing on a SONAR project from a year ago!  Very annoying.
 
No problems with Studio One.

I used these posts last year to get my FP working. this year I upgraded my computer to a 64 bit , Windows 7 to be exact. While I am running sonar and all plugins in 32bit, nothing on this thread seems to work for me. everytime I type the command prompt in I get an error message saying "specified module could not be found" and to make sure the binary is stored at the specific path. This alas means nothing to me. PLEASE HELP

Have to use full paths for the dll.

Place the correct dll in the surfaces folder.

then open an elevate command prompt, copy the line below, right click in cmd windows and paste, press enter.   quotes are required.

64 bit:
regsvr32 "C:\Program Files\Cakewalk\Shared Surfaces\faderport.dll"

32  (don't have a 64 booted now, so adjust as needed.)

regsvr32 "C:\Program Files (x86)\Cakewalk\Shared Surfaces\faderport.dll"

jm24 you are a wizard a true star! I have been wrestling with this ever since I got my new system 2 months ago, and you just solved it in 5 freaking minutes! Bless you bless you a million times. I am much relieved! I shoulda posted sooner.

To make the Presonus Faderport work with Sonar X2 do the following things:
 
1/ download the driver installer package from teh presonus website @
[link=http://www.presonus.com/uploads/products/1243/downloads/FaderPort_135_617.exe]http://www.presonus.com/u.../FaderPort_135_617.exe[/link]
2/ Now on your PC;   navigate to the ‘64bit dll’ file which is situated within;
C:\Program Files (x86)\PreSonus\FaderPort\FaderPort Dll\Sonar\x64’
3/ copy and paste this to;
C:\Program Files\Cakewalk\Shared Surfaces
4/ run the command prompt by clicking
Start
Programs
Accessories
Command Prompt  - (Right click and select: ‘Run as administrator’)
5/ Paste this into the command prompt window, (directly after the last piece of existing text)
cd C:\Program Files\Cakewalk\Shared Surfaces\ 
C:\windows\SysWow64\regsvr32 FaderPort.dll
6/ Press ‘Enter’
7/ Close command promt box
8/ Open Sonar X2
9/ Open any project
10/ Click on the Contorl surface box at the top.  (it may say ‘no control surfaces’ assuming you have none at present) and click ‘Select hardware/controller surface’
11/ Click on the yellow star symbol at top right corner
12/ from the ‘controller/surface’ drop down box select ‘Presonus Faderport’ (This will appear now as an available choice, whereas it did not before, right?)
13/ from the ‘input Port and output Port drop down boxes, select Faderport, and then hit Enter
When you click enter, you will hear your Fader on the Faderport return to zero.
 
Your done!     Hooray!!!!!!!!!!  

Also supposed to enable key aftertouch, and channel aftertouch.

=================
It is not working for me: w7 and w8, 8.5.3, and x2.

I have spent way too many hours on this.

'Tis possible it is some kind of interferance with the drivers used by the audio/midi interface.

I will have to get a new interface to use with w8.  X2 will not work with the EMU 1820. 8.5.3 does.


After I get it to work, (Never does control buses), I cannot reopen sonar. Sonar hangs and the fader moves erratically, and the mute button flashes.

Anybody got at least a 2 in 2 out 24 bit interface with midi I can borrow?

My audio interface is an Emu 1616M.
I have experienced a few hangs and BSOD crashes.
These happend as i pressed the REC button on the faderport!
The Emu could be the problem im not sure?

But that aside it works well and has let me record and mix a few tunes.

A VERY big THANK YOU to ALL who've posted in this thread.
Now have Faderport working like a dream in X3d.

  Just got mine working awesome post.
i bought this for times like now when i'm on the road away from the studio.
