THE LOOPCOPY PARAMETER
Does the LoopCopy parameter work yet? What does it do?
The previous Echoplex upgrade, LoopIII v5.0, implemented the LoopCopy feature. The versions before that, LoopIIIv3.2 and LoopIIIv3.0 did not have it. LoopIV of course has this also. Here is info about this parameter from the LoopIIIv5.0 upgrade release notes:
Loop Sound Copy
The long absent loop copy function arrives! This function allows the user to easily and intuitively copy his current loop into the next loop, during performance. When NextLoop is pressed to jump to a reset loop, the copy process begins. While copying, the loop continues to play, so the performance is seamless. Even better, during the copy, overdubs can be made on the new version! And just like the Multiply function, the new loop can be made to have as many multiples of the original as will fit in memory. With two button presses, you can take a one bar rhythm in loop 1 and turn it into a sixteen bar vamp in loop 2 with a melody recorded over the top!
Loop Time Copy
This function is very similar to the sound copy, but just copies the length. And, in the same fashion, you can overdub during the copy and create multiples of the original length. Keep your loops in a tight groove!
If you are still using LoopIIIv3.2:
I pressed the LoopCopy parameter and nothing happened. I'm using LoopIIIv3.2.
The parameter itself does nothing in the v3.2 software. What happened there was, the ship date was looming, the front panels were already done, and the LoopCopy parameter had not been implemented because we hadn't yet agreed on what it was supposed to do. So we left if for a future upgrade. LoopIIIv5.0 has it.
Other methods of Loop copying with any version:
Are there other ways to do a LoopCopy? Can I do LoopCopies selectively, without having to turn the LoopCopy parameter on all the time?
Loop copying is still quite possible even without the LoopCopy parameter! Its done with what we call "cross functions," where ending one function with a different button press gives you a special function. In the case of copying audio it's the Next-Multiply combination when SwitchQuant is on. You can also copy the loop's time base without audio by using Next-Insert. You do it like this:
Set up multiple loops with the MoreLoops parameter.
Turn SwitchQuant on.
Record a loop in Loop 1.
At some point before the end of the loop, press NextLoop.
You will see the "ooo" display, which means the function is being quantized to the end of the current cycle time. In the manual, Warren calls this the "Lame Duck Period." If you do nothing more, the echoplex will switch to Loop 2 when it reaches the end of the current cycle of Loop 1. We are going to do something though, since we have several special funcitons available during this waiting period, one of which is LoopCopy. So:
While the "ooo" display is on, press Multiply.
Now when you reach the end of Loop 1, the echoplex will jump to Loop 2 and begin copying the audio from Loop 1. You will essentially be in the multiply function, with Loop 1's audio being multiplied in Loop 2.
While the loop is copying, overdub is essentially on, so any playing you do is added to the loop. (just like in multiply)
Repetitions of Loop 1 will continue to be added to Loop 2 until you end the function. (also like multiply)
End the copy by pressing multiply at some point before the end of the last repetition you want.
The Echoplex will round off to the end of the cycle and begin looping the copied audio and any overdubs you made. (again, just like multiply)
This seems a bit complicated when written out, but its actually pretty easy and intuitive to use. I use it all the time, and its one of my favorite Echoplex functions. I can record 1 bar of music in loop 1, Press Next-Multiply to start copying it in loop 2, overdub a melody while 4 repetitions of the loop are copied, and end with another press of multiply, all in just 3 button presses! You can also choose the loop to copy to by pressing NextLoop several times before pressing multiply. So to copy Loop 1 to Loop 4, I would press Next-Next-Next-Multiply. And it all happens seemlessly to an observer, so it's very usable in musical situations. Give it a try!
This is actually explained in the manual. Its non-intuitively located in the description of the SwitchQuant parameter.
In the newer upgrades, the mythical LoopCopy parameter has finally become real. Its function is similar to AutoRecord, where the Echoplex automatically copies the loop when you switch to a reset loop. The parameter values are "off", "sound", and "time". Its quite useful in some situations, although I actually prefer the old way most of the time.
