    Hi,

    installed Profiler OS 9.0 and connected the USB to a Linux (Debian) computer. The Profiler USB audio interface is detected an can be selected for output and input. There is just no audible audio sent to the Profiler. There is random crackling only. The input is silent.


    Did anybody manage to connect the Profiler USB audio to Linux successfully?

    You should still be able to record the Kemper guitar signal alone if you turn down “Aux In >Main” in the output menu page 5.
    Monitoring your DAW via AUX inputs on the Kemper has to be done via headphone out in this case.

    Good idea!
    Additional metadata like picture, sound clip, details and history of amp or the full profiling story could be added to a profile in a XMP sidecar file. This method is widely used for RAW photographs. It would keep the original profile kipr file small and compatible while allowing for maximum flexibility and portability.
    See XMP

    There is another option for monitoring without additional mixer, without 2nd set of speakers and independent of sound card capabilities:
    Connect monitoring speakers to KPA Main Output or headphone to Headphone out.
    Use S/PDIF for recording.
    Connect the playback/monitor signal from sound card to KPA Aux input.
    In KPA output settings turn up Aux In.


    Connections:


    KPA - - - - - - - - - Sound Card
    S/PDIF out ---------> S/PDIF in
    Alternative Input <-- main/monitor out R
    Return Input <------- main/monitor out L
    Main Output R -----------------------------> monitor speaker R
    Main Output L -----------------------------> monitor speaker L
    (Headphone --------------------------------> headphone)


    Additional advantage of this approach is lowest latency monitoring.

    The procedure explained above is equivalent to using an external monitor mixer. You just don't need the external mixer while recording a single guitar.
    While recording the guitar dry (output source "Stack" or "Git / Stack") post amp effects could still be added to the monitor signal in the KPA (e.g. modulation effects, delay, reverb, Headphone Space). This allows for comfortable guitar sound in the monitor while keeping all options for mixing mod and space effects later.

    Yes, this is about monitoring tracks from the DAW through the KPA while recording.


    The analogue outs of the KPA could be used for recording of course. The disadvantage of that would be loss of quality due to additional D/A and A/D conversion. Using S/PDIF the digital signal could be recorded unmodified.

    Problem: The preferred connection for recording is via S/PDIF to stay in the digital domain. Many affordable sound cards don't provide zero/low latency hardware monitoring for S/PDIF inputs. The signal would have to be routed and monitored via DAW which inevitably adds annoying latency.


    Solution: A simple solution without using external mixers is the headphone or main output of the Kemper for monitoring. These outputs provide the Kemper's signal without additional latency. Adding the playback signal to the headphone/main out can be done via Auxiliary input.
    Added bonus: While recording the guitar dry (output source "Stack" or "Git / Stack") post amp effects could still be added to the monitor signal (e.g. modulation effects, delay, reverb, Headphone Space). This allows for comfortable guitar sound in the monitor while keeping all options for mixing mod and space effects later.
    Note: The Auxiliary input will not work while using the Hardware Effects Loop in your rig.


    The signal chain:
    Kemper <-> Soundcard
    S/PDIF Out -> S/PDIF in (for recording)
    S/PDIF In <- S/PDIF out (for re-amping only)
    Alternative Input <- monitor out R (playback )
    Return Input <- monitor out L (playback)


    DAW settings:
    Route the monitor/playback signal to the audio out ports connected with Kemper.


    Kemper settings:
    Use Auxiliary input control in the output section to adjust the level of the monitor/playback signal.


    Future improvements: Using 'S/PDIF In' on the Kemper for the playback signal is currently not supported. Maybe this could be added in a future firmware update. The advantage would be less cables and no analogue connections between Kemper and DAW.

    The favourites information is stored in rig tag number 5. If the name stored in this tag matches the KPA owner it is considered a favourite.
    You could easily check and change this information with the KIPR Tag Editor.


    The latest version of KIPR Tag Editor can directly handle backup files. Backup files can be extracted and created without renaming or additional tar programs.

    Maurizio,
    I did look into performance files already. Was thinking about a Performance tag editor. Extracting the individual rigs from performance files should be possible. There is only so much time for programming, music and the rest.

    Gianfranco,
    You are right that it's bad behaviour to access the internet without notification.
    Concerning the error message: There are two versions of the Windows installer available:

    • Windows binary
    • Windows AMD64 / Intel 64 / X86-64 binary


    The later will work with 64 bit processors and 64 bit Windows only. Did you download the correct version?

    Gianfranco,
    I can understand your concerns. Downloading open source and community developed Python from the official web site (http://www.python.org/) and verifying the checksum or signature should give you more confidence than the average Windows program can offer. If you prefer you may use a commercial Python version from ActiveState. Don't know how this would be more secure though.
    One of the reasons the Tag Editor(s) are written and released in Python source code is that you don't have to trust us. You can check the program yourself.
    Btw.: Did you try to install Python with internet disconnected?


    DigitalBliss,
    If you are worried about Windows doing things behind your back - run KIPR Tag Editor on Mac OS X or Linux. Python is pre-installed on most of these systems.

    Hi Gianfranco,


    I don't know the reason. I assume depending on your system configuration the Python installer is downloading required packets. To make sure you have got the original unmodified Python installer you should verify the MD5 checksum of the downloaded file or download and verify the signed file. See detailed Python 2.7.6 page.


    Instead of the installer you could download the source tarball and compile yourself (not supported for Windows).

    New feature:

    • Extract and create kpabackup files


    No additional TAR or ZIP programs necessary any more to handle backup files!



    kpabackup File Handling


    kpabackup files are created with the Kemper Profiler Backup function and contain a backup of all rigs and presets in the Kemper Profiler. These files are saved on the USB memory stick in directory "Backups" an can be transferred to and from your computer.
    See Kemper Profiler Reference Manual - External Storage


    Extract A Kemper Profiler Backup Archive On Your Computer
    The KIPR Tag Editor can unpack kpabackup-files to access all rigs and presets contained within. No additional tar program necessary.


    Menu:
    File - Extract kpabackup file...


    Select the kpabackup-file to unpack and the target directory to put the unpacked files. A new directory will be created in the target directory containing all files from kpabackup. E.g. sub-directory "Rigs" contains one kipr-file for each rig on your Kemper Profiler.
    Now you can start your clean-up work and delete rig files you don’t need anymore or add rig files from your collection.
    For getting an overview of the backup contents you may generate a csv-file containig a list of all files and their tags (Menu: Files - "Generate csv file from directory")
    Tags contained in the kipr-files can be edited file by file or with the batch function of the KIPR Tag Editor.


    Create A Kemper Profiler Backup Archive On Your Computer
    After cleaning up the kipr-files in your backup directory you can pack everything into a kpabackup file to be transferred to the Kemper Profiler.


    Menu:
    File - Create kpabackup file...


    Select the directory containing the unpacked files from your backup (including your modifications) and the target directory to put the generated kpabackup file. The kpabackup filename will contain current date and time.
    This file could be put on the USB memory stick in directory "Backups" to transfer to the Kemper Profiler. There you could start External Storage - Backup - Restore and select this kpabackup file.
