If you want the looper that the pros use, this is the one. The Rang™ III is the best looper for live 
performance, bar none. The full retail price is $589, but your local dealer can do MUCH better than that. review of the Rang™ III - a new & very informative website for the looping musician  <

•  Easily syncs to an external MIDI clock source. The MIDI Start and Stop commands are supported as well.
•  Flexibility provided by 4 distinct Play Styles.
      Serial Play Style - loops play one after the other for building a song in verse/chorus/bridge fashion.
      Serial Master Play Style - For serial style loopers it's nice to have a rhythmic background behind the melodic loops. Mute 
          the strings and record a short "chika-chika" or beat on the sides of your acoustic axe. This rhythmic master loop can 
          then play along with any other loop.
      Sync Play Style - all loops can play simultaneously and are synced so they stay together.
      Free Play Style - all loops can play simultaneously and are NOT synced; this is great for creating ambient soundscapes.

•  3 or 4 loops - your choice.
•  Maximum recording time varies but can be as long as 35 minutes.
      48KHz true stereo recording yields about 4 1/2 minutes
      48KHz mono recording yields almost 9 minutes
      24KHz true stereo recording yields almost 9 minutes
      24KHz mono recording yields over 17 1/2 minutes
      12KHz mono recording yields over 35 minutes

•  Stacking - "stacking" is adding a part to a loop (There is no limit to the number of parts you can stack.)
•  Undo/Redo - the last part stacked can be muted, then played again or rerecorded.
•  Erase - loops can be erased one at a time or all at once; some loops can be erased while others plays.
•  Copy Loop - a complete loop can be copied whether it is playing or not.
•  Copy Live - this enables "re-sampling" and is very powerful; the pedal's output is routed to a new loop.
•  Octave - plays loop an octave lower - your choice of original tempo (instant bass part) or playing at half speed.
•  Reverse - loop plays backwards.
•  Once - loop plays one time through then stops or if already playing, it stops at its end.
•  Stutter - enables repeatedly starting a loop over before it plays all the way through, sort of like record scratching.
•  Fade - loop(s) fades in or out with one button press; fade time can be 3 to 43 seconds.
•  Reverse Solo - this is a built-in effect and enables you to create reverse leads live.
•  Two Sample Rates - 48KHz or 24KHz, both use 20 bit samples; through signal is always 48KHz / 24 bits.
•  Thru Mute Function - turns off through signal.
•  Expression Pedal Jack - connect an expression pedal for foot control of overall playback volume or Decay Rate.
•  Volume Knobs
      Serial & Serial-Sync Play Styles
          Volume controls playback level. Vol 2 - Vol 4 do nothing in these Play Styles.
      Sync & Free Play Styles
          Volume controls playback level of loop 1
          Vol 2 controls playback level of loop 2
          Vol 3 controls playback level of loop 3
          Vol 4 controls playback level of loop 4
•  Decay Rate Knob - sets the rate at which earlier parts fade when new ones are added; continuously variable from 0-100%.
•  Stereo or Mono - recording and playback will be stereo or mono depending on which of the Smart Jacks you use.
•  Smart Jacks - the Rang™ III senses which jacks are being used and provides different signal routing options.
•  Rugged 9" x 6" x 2" steel chassis. It's much smaller than the other loopers that approach the III's power.

*Software Version History *
Version 1.0  2009, Aug - This is the initial release that supported all the Bonus button functions but had only Serial and Serial-Sync Play Styles.
Version 2.0  2010, Sep - Our original concept of the III was completed with the addition of Sync and Free Play Styles.
Version 2.1  2011, Jul - Added support for the Side Car™ controller and the ability to control Decay Rate with an expression pedal were added.
Version 2.2  2012, Jun - Just a bug fix. Only one player came across this particular cockroach, but it was significant enough that we spent time squashing it.
Version 3.0  2012, Dec - Added quantizing loops to an external MIDI clock allowing it to play in sync with the MIDI clock. MIDI Start & Stop commands are supported.
                                    Jack monitoring - It's no longer necessary to plug in signal cables before powering up. Cable changes are recognized on the fly.
Version 3.1  2013, Nov - Added "Brother Sync" capability. Multiple III's can play synchronously WITHOUT an external MIDI clock. Added Reset function.
Version 3.2  2013, Dec - 2 bug fixes: (1) fixed volume problem when running 2 inputs & 1 output, (2) adjustment to ensure exp pedals take Decay Rate to zero.
Version 3.3  2014, May - Added "active" MIDI sync algorithm; a serious improvement over V3.0. Your loops will stay with an external MIDI clock signal FOREVER!!
Version 3.4  2014, Sep - Added an easier way to record and play a loop with Stacking active; it only requires two loop button taps. And a small bug was fixed.
Version 3.5  2017, Mar - Added a new option for the Octave effect. A recorded loop can be processed so it plays an octave lower and at the original tempo. Instant bass part!

How to determine which software has possessed your III

    Deciding between software Version 1.0 and newer releases

        Power up your III. If the Serial Play Style light is on bright, it has Version 1. If any 2 Play Style lights are on dim, it has Version 2.0 or higher.

    Determining exact software version

        To verify which software version has possessed your III, hold down the loop 1 button and yellow Bonus button through out the entire
        power up sequence (about 10 seconds). You'll end up with the clock's center light on and possibly one other light. Release the buttons.

        Press loop 1 to see the first digit of the software version; the clock display shows you. Release and press loop 2 for the second digit.
        Release and press loop 3 for the third digit.
        050        = V1.0 - 2009, Aug
        103-104 = V2.0 - 2010, Sep
        111        = V2.1 - 2011, Jul
        114        = V2.2 - 2012, Jun
        118-122 = V3.0 - 2012, Dec
        125        = V3.1 - 2013, Nov
        127        = V3.2 - 2013, Dec
        129        = V3.3 - 2014, May
        131        = V3.4 - 2014, Sep
        134        = V3.5 - 2017, Mar

** DO NOT begin a download until your III has completed its initialization & power up sequence - This takes at least 10 seconds.

** If a download renders your III inoperable, all costs associated with fixing it are your responsibility. ** Downloading software is NOT covered by warranty. ** This is necessary due to the unpredictable nature of using a wide range of computers, operating systems, drivers and hardware interfaces. Having said that, hundreds of customers have performed software downloads without a problem. In fact only 5 have actually "bricked" their pedals.

*Here's a cool quote from Daniel Lanois' biography "Soul Mining" *
"Some of the compositions for Sling Blade (the motion picture; starring Billy Bob Thornton) were made without the orchestra. I would rise up in the night from 
the orchestra pit and plug into my ever-evolving guitar rig.  At the time I was very excited about a recording box called the Boomerang. This would allow me to play 
a chord sequence and then play on top of it without anyone else in the room. This brought back memories of some of my very early recording rigs when I was a kid.  
The sound-on-sound technique that I used back then was still with me twenty years later at the Teatro. [...]

The opening piece of music in Sling Blade invokes a dark, menacing, haunting mood, built with my Boomerang and Les Paul rig. [...]

No multitrack was used for this composition; it was essentially a live recording.  Every stage of the Boomerang lasted roughly forty-five seconds, every new stage 
accommodated the preceding one.  Each stage would be a roll of the dice because if you made a mistake, you'd have to start all over again. [...]

This opening piece of music is called "Asylum". I believe it is one of the most reaching pieces of music I've ever created, very much in the Eno tradition, built 
with just a few tools, but with much concentration. "Asylum" runs through the entire beginning of Billy's movie. It sets a tone, keeps you on the edge of your seat [...]

Sling Blade became a contemporary classic; it won an Oscar..."
