    • I installed the new upgrade and it doesn't work! What's wrong?
    • How do I know which version I have?
    • What is the history of software upgrades for the Oberheim Echoplex Digital Pro?
    • Why is it called LoopIII? and what happened to LoopIII v4.0?
    • LoopIIIv3.2 was supposedly buggy. How do I know the 5.0 version isn't just as bad?
  • SIMMs, memory, etc.
    • How much memory does the Oberheim Echoplex come with?
    • Can the Oberheim Echoplex's memory be expanded? What is the maximum?
    • What type of memory does the Echoplex use?
    • How come it can't be expanded beyond 16MB?

• Page 2 - Parameters
  • The Loopcopy Parameter
    • Does the LoopCopy parameter work yet? What does it do?
    • If you are still using LoopIII v3.2: I pressed the LoopCopy parameter and nothing happened. I'm using LoopIIIv3.2.
    • Are there other ways to do a LoopCopy? Can I do LoopCopies selectively, without having to turn the LoopCopy parameter on all the time?
  • MIDI Sample Dump
    • Does the Oberheim Echoplex support MIDI Sample Dump?
    • Is MIDI Sample Dump a good way to save my loops?
    • So why is it even available in the Echoplex?
    • If one was going to do a sample dump anyway and wanted to use something other than a computer with hard drive, what would you recommend?

  
  

• Page 3 - Sync
  • Echoplex Midi Syncing
    • Can the Echoplex sync to external midi clock? What kind of rhythmic meter can I use?
    • What about syncing something else to the Echoplex?

  
  

• Page 4 - Stereo Echoplexes
  • General Stereo Oberheim Echoplex Questions
    • Can I run my xyz device, with stereo outputs, into the Oberheim Echoplex?
    • How do I set up two Oberheim Echoplexes to work together as a stereo pair? I have the new Loop III v5.0 software in both.
    • When I put one machine in record, is the other one supposed to automatically follow? What about the feedback knob? Can I set one or do I have to set both?
  • Stereo with older Echoplex software versions
    • If I am using the old 3.2 version of software, how do I set up two Echoplexes to work together as a stereo pair?
  • Troubleshooting Echoplex connections
    • I'm having problems getting two echoplexs to work together in stereo. Does this sort of stereo operation really work? How can I figure what I'm doing wrong?
    • I have a cable going from one brother connector to the other brother connector. And a MIDI cable from the master out to the slave in (as stated in the manual). When I power up, I get ERR on both units! This disappears if I unplug the brother cable (on each plex) and then plug it back in again.
    • I'm using a TRS cable and I'm still getting the "ERR" message when powering up Stereo echoplexes. What could be the problem?
  • Stereo Echoplex Feedback Connections
    • How do I use a pedal to control feedback on stereo units?
    • When the feedback pedal is plugged in normaly the loop/delay parameter gives you 3 possibilities loop, del, out. In stereo mode the slave doesnt get the 3; only loop and del.

  
  

• Page 5 - Old Bugs
  • Volume Swells, Noisegates, and Threshold
    • What does the Threshold Parameter do? Does that have anything to do with the noisegate I heard about?
    • So what is this Noisegate thing then?
    • I had a problem where tbe beginning of a volume swell was cut off in the recorded loop. (or:I heard there is a problem with volume swells.) Is this fixed?
  • Feedback Degeneration when Controls are set to 100%
    • I heard that loops on the Echoplex slowly fade away, which means it can't really loop. Is this true?
    • I have an old Oberheim Echoplex unit, and I sometimes have the loop audio slowly degrade when I leave the loop going for a long time. Can this be fixed?
    • I have a stereo setup with two Echoplexes and v3.2 software. Sometimes the loop fades out on the slave even though Feedback on the master is all the way up. Is there a fix for this?

• Page 6 - Hardware Questions
  • Audio Distortion, the Internal "Limiter," and Input/Output Gain Modifications
    • Sounds with high frequencies sound funny. Seems like there is some sort of clipping?
    • I heard there's a limiter?!
    • I don't like the gain structure in the Echoplex. The input gain is too sensitive and the output gain is not loud enough. How can I change it?
  • Static and the Foot Pedal
  • Reliability, Thermal Problems, IC Pin Modifications, Undo Malfunctions
    • I heard that there is a reliability problem with installing the maximum memory on an Oberheim Echoplex, causing thermal troubles. Is this true?
    • I pressed Undo and the Echoplex started Record, which killed my loop! How do I prevent this?
    • I've heard that the Echoplex has thermal problems and is not reliable, is this true?
    • Diagram of the IC pin modification

  
  

• Page 7 - BrotherSync Questions
  • Multiple Echoplex and BrotherSync - how?
  • BrotherSync Setup and Usage
    • How do I set up and use BrotherSync with two (or more) Oberheim Echoplexes?
    • Is there anything special I should know beyond what it says in the manual to use BrotherSync?
    • Does the memory in both Echoplexes need to be the same?
  • BrotherSync In-Depth Tutorial
  • BrotherSync Trouble Shooting
    • When leaving the brother sync plugged at power on, the plexes refuses to boot.

  
  

• Page 8 - Feedback Questions
  • Understanding Feedback and What It's Good For
    • Why would someone use feedback with loops?
  • Understanding the Echoplex's Feedback Implementation
    • What controls does the Echoplex have for Feedback?
    • How does Feedback work on the Echoplex? What's going on inside?
    • So, does the Feedback effect occur after the current cycle, or after the whole loop?
    • Once feedback causes the loop to die out, I assume its gone forever?
    • Sometimes the feedback level is unpredictable, ie, it seems to not wait til the end of the loop to reduce in volume, and if I push the pedal up (off), the sound will stop, but sneak back in somewhere in the loop. Also, if I push the pedal off about halfway, and let the loop slowly die out, then push it foward, so it continues to repeat indefinately at this new, lower volume, the volume of the loop jumps erractically-it doesn't stay at a steady volume. Does this sound like a midi, pedal, or user problem?
  • Feedback Pedal Control
    • Is the feedback pedal input on the Echoplex Digital Pro audio or CV?
    • There is a 100k pot in my pedal, would that work ok for the feedback jack?
    • Can the feedback range for a pedal be set in the Echoplex?
    • How do I make my own feedback pedal/controller for the Echoplex?
  • Feedback Trouble Shooting
    • I understand how feedback works, but things are behaving erratically anyway. Feedback levels seem to be jumping around. Is there anything I can do to fix this?

• Page 9 - Multiple Loops and Loop Switching
  • Multiple Loops, General Questions
    • How many loops can the echoplex have? Are you stuck with a set number or can you change it?
    • When using multiple loops are successive loops confined to the first loop length a la JamMan?
    • Does the Echoplex allow you to record different loops separately which can be triggered, stopped and retriggered separately?
    • Can the Echoplex play separate loops simultaneously (and record on one while another is playing), like a polyphonic sampler triggered from a MIDI controller?
    • Why do loops seem to start in random places when I switch loops? Is it possible for loops to trigger at the startpoint when using nextloop?
  • Using Multiple Loops
  • SwitchQuant Parameter
    • For the switch quantize parameters the manual doesn't seem to be updated for the latest version of the software. What are CYC (cycle?) and Cnf?? And what do they do?
    • Is this SwitchQuant stuff in the manual anywhere?
    • How do I use the waiting period for a quantized loop switch to start a loop copy?
    • If I hit NextLoop, it switches to the next loop at the end of the current *cycle* and does not wait until the end of the whole loop, unlike what the manual says. Is there any way to get it to do what the manual says it should do?
  • Loop Switching to Any Loop
    • Why no "Previous Loop" button? Is there a way that "Next Loop" gets you back to Loop 1 without going through dead loops?
    • If I were to record 9 different loops on the echoplex could I access each loop (go from loop 1 to loop 5 to loop 3 to loop 8) with one touch of a button on the echoplex pedal board or do I have to tap the next loop button till I get to the loop I desire?
    • I need to take multiple loops, (a,b,and c) of a tune, then be able to change to a,b or c after they're written, on the fly and lay the parts to tape. Is this possible?
    • If #Loops=2 and you are recording the second loop, is there a way to conclude recording and instantly go back to loop 1?
  • Loop Triggering with Midi
    • Can loops be switched with Continuous Controller messages?
