Importing ARP patterns

Hello, I have a bunch of Alesion ARP presets that I would like to play around with in Sonar.
How do I import them?

FWIW, I just tried a few in X2, they work fine. The arp directory has been moved into a SONAR version specific directory under "Cakewalk Content"

Forgot about them when I moved to my new machine. Thanks for the link to the resurrected P5 page.

I remembered it was 8.5 that introduced the arp.

I'm not sure whether that means you were able to install the arps (having S8.5 or greater), or not.
 
 
Just to flesh out the arpeggiator progression a little:
 
-  Project5 version 2 added the per-track arpeggiator (was it 2005?).  In reality an inline MFX, it had the exact same structure & feature set that you'll find in Sonar.  No "print-to-track" capability without virtual MIDI cables and/or Rewire.
-  After P5's untimely demise, these donor organs were transplanted into Sonar 8.5.
-  Sonar has the ability to import .ptn files [File -> Import -> MIDI ... Files of Type: P5 Pattern].
-  Sonar's arpeggiator can load .ptn files as a basis for new .arp presets [Presets ... Open Preset.  Files of Type: P5 Pattern].
-  Sonar's arpeggiator can save configurations as .arp presets [Presets ... Save Preset].
-  I know of no other method to save tracks, 'groove clips' or .mid files as .ptn files (except Project5 2.0 or greater).
 
Bottom line: Sonar can save variations on its loaded .arp presets, but you'll need a source of P5 pattern files (or Project5 installed) to build new arpeggiator presets from scratch.

Sonar doesn't recognize *.ARP files.

It will, but it has to be from the Presets ... Open Preset dialog; within the arpeggiator itself.  The File / Open / Import paths won't apply here.  Extract the Alesion ARP Presets directly to Sonar's Arpeggiator folder.
 
That folder will be in a slightly different location, depending on your Sonar version and Windows O/S.  Look for clues in my post above, or in the Alesion ARP Documentation.
 

it would be nice to be able to convert those to midi

You may not intend this to be interpreted literally, but there is also a 500-file download containing the core P5 pattern files (*.ptn) that the 500 .arp presets were built from.  Now those files can be directly imported into Sonar.  [Note:  Coarse quantization settings will decimate those pattern files during editing.]
 
There are some outdated links to the Alesion PTN Construction Kit (should you need it).  I'll have to hunt around a little for my original storage location.

 
The Technetos site no longer has the file "Alesion ARP Presets.zip" which contains .arp files.  It has only the Alesion PTN Construction Kit which contains the .ptn versions of the arp files.  Does this matter ?  The .ptn files are just a rythm of a single note when dragged into Sonar.  Is pitch encoded somehow, or is the resultant pattern played by the Inspector's arpeggiator a combination of the rythm in the .ptn and the 'Shape' button/selection in the Inspector ?  If the .arp files are useful, is there anywhere where I can acquire the zip file ?  The Wayback Machine has links to it, but the file itself is not archived, unlike some other Sonar-related zip files.

The arp presets are at http://patcharena.com/downloads/index.php?subcat=108. The file is called "Alesion ARP Presets.zip"

Thanks Steve for your help.  Don't know why I failed to find the file yesterday as I just tried again and succeeded.  Too late to play with them tonight...
