Introduction

Thanks and what the heck did you just buy, anyway?

Thanks for your purchase, and congratulations on being the proud new owner of a Mod Pro, part of Line 6’s Studio Modeler line of products. We hope that your new toy will make your musical and creative life more fun, exciting, fulfilling, and will stop the awful drip under the bathroom sink (although we suspect you're gonna have to break down and call a plumber for that one).

If you're familiar with Line 6’s award-winning series of Stompbox Modelers—the DL4 Delay Modeler, MM4 Modulation Modeler, and FM4 Filter Modeler—you’ve already got a pretty good idea of some of what your new Mod Pro can do. We’ve added a lot of new features and capabilities to the Studio Modelers, so you’ll want to give this manual at least a quick once-over, if not a thorough reading before diving in. Don’t worry, we’ll try and make it as painless as possible. If you’re not yet familiar with Line 6 products, let’s start with a brief introduction. But first, you’ve filled out that attractive registration card and put it in the outgoing mail, right? No? Well then, have you logged onto registration? If you haven’t yet, that’s okay, we’ll wait here…

Who is Line 6?

Hi! We’re Line 6. As you may know, Line 6 first came on the scene with a new kind of guitar amplifier – the first to put digital software modeling technology to work in a combo amp for guitarists. In order to pioneer this technology, we focused our efforts on the vacuum tube, the little glass wonder that sat at the heart of most every great guitar amp in history – plus quite a few stomp boxes, effect processors, and other pieces of great audio gear. The Line 6 crew assembled a dream collection of amplifiers recognized by guitarists the world over as true “tone classics,” and, with a guitar in one hand and modern computer measuring gear in the other, put these amps through their paces and got them to give up their secrets–a guitar pickup output, after all, is an electronic signal, and tubes and the rest of the guitar amplifier electronics are really just a complex form of signal processing. These electronic explorers thus distilled the noble history of guitar tone heritage into a revolutionary, patented DSP (digital signal processing) software-based modeling technology which gave Line 6 the power to create super silicon-based life forms like our history-making amplifiers and POD.

Introduction

Who is Line 6?

1 •

Well, it’s been some years since the first Line 6 amp brought modeling to the combo amp world, followed by the Line 6 POD that revolutionized the world of guitar recording. During that time, our thoughts have often turned from our amps to our feet. We started thinking about all those great stompboxes that have been as much a part of the electric guitar experience as the amplifier. So, turning from our massive collection of vintage amps we had assembled for our first products, we began the task of assembling the most in-demand and hippest stompboxes ever made in order to put them through the same rigorous modeling procedures. Many a night we had to stay up late comparing different delay pedals, and on the weekends we had to haul vintage effects home for more testing in our personal studios. (Yes, it's a rough job, but someone has to do it.) When all was said and done, though, we had created a series of Stompbox Modelers, each one containing a dream collection of lovingly crafted digital software models of a whole carpet-full of the great effects of guitar history.

Once we'd accomplished that, our attention turned to guitarists who love rack gear, as well as keyboard players, recording engineers, home recordists, and other nonguitarist types. After all, they needed these sounds, too! One night, a vindaloo inspired dream came to us, in which a voice called out, “Rackmount! With serious MIDI functions, too!” Never ones to ignore visions brought on by amazingly hot, yet tasty food, we started work on what you now hold in your hands.

Quick Start Guide

Hate long-winded manuals? Want to use your Mod Pro having to worry about any details? Here’s the important stuff to know:

1. Hook It Up

Input (for mono sources) or both

– Plug the output of something into Mod Pro’s rear panel

R/Mono

and

Left

the Mod Pro outputs to the input of whatever you’re feeding the Mod Pro to— guitar amp, mixing board, etc. Chapter 3 has more details.

2. Power It Up

and

Output

knobs on your Mod Pro all the way

whatever is receiving Mod Pro’s output signal, so you’ll hear what you’re doing.

3A. Crank It Up: Guitar Source

– If you’re connecting a guitar directly to Mod Pro and running straight into the front of a guitar amp, turn the Mod Pro knob way up (probably to max if you’re using standard passive pickups). Don’t expect to hit the yellow or red lights on the Mod Pro input meter; you’ll most likely only get to the green. Don’t set the Mod Pro

Output

Pro can put out a much hotter signal than your guitar can and will overload the front end of your amp if you do.

3B. Crank It Up: Line Level Sources

– If you’re feeding Mod Pro a signal from a line level source (keyboard, mixing board, etc.) do this: while sending a healthy signal to your Mod Pro, turn up the Mod Pro

Input

ﬂashing red occasionally, then back it down just a hair so you're living in the yellow zone.

Avoid hitting the red in normal use

. Next, press the Pro and turn up the output volume until the meter on your mixer (or whatever) reads about the same as the input meter. (Hint: With most line level signals, both the input and output knobs should be pointing at about 3 o’clock. It’s not a hard and fast rule, but a good starting point.) Now, press the Bypass button again to let the Mod signal through. If you made all your connections correctly, and remembered to turn up the Aux send and return and other levels on your board (D’oh! Been there, done that!) you should be hearing Mod effects.

OUR

UIDED TOUR

There are several types of tourists. First, there are the ones who sign up with the tour group, read the itinerary in advance, hang on every word of the tour guide, and come home with a solid overall understanding of the new place they’ve visited, although they may have missed that neat little cafe that was just up the side street they rushed past on the way to another museum. Then, there are the adventurous types who just strike out on their own, wander around, ﬁnd that little cafe – but who might wander into the wrong part of town and get into trouble. Finally there are the (in our opinion) wiser tourists who read the guide book before travelling, ask questions, use small tours to ﬁgure out where they want to come back and visit in more depth, and still leave themselves a chance for some adventure. In an attempt to join this last group, let's take this opportunity to look at all the controls and connections that your Mod Pro has, and give you a little bit of explanation of what they do, shall we? You've got a lot of control at your ﬁngertips here, and you don't want to miss out on any of it.

25. Expression Pedal Input – Plug the optional EX-1 expression pedal in here.

26. +4dBu Balanced XLR Out Left – This audio connection keeps ground separate

from the signal by running 3 lines; two conductors (+ and –) and a ground/shield. This type of connection significantly reduces noise with longer cable runs, and enables hotter levels to be transmitted (which is a good thing). There's a certain amount of controversy about which pin should be “positive” or “hot”, so it's always a good idea to check. (Some manufacturers have staked their claim to pin 2, others to pin 3. We come down firmly on the pin 2 side.)

27. +4dBu Balanced XLR Out Right

28. –10dBV Unbalanced 1/4-inch Out Left/Stereo – When you connect a

1/4-inch unbalanced cable (like a guitar cable) this functions as the left output. To connect to the FX Return of a POD Pro, Flextone II, or other Line 6 product that uses 1/4-inch TRS connections for its loop, use a 1/4-inch TRS cable and connect to the loop’s return jack. “TRS” means Tip, Ring, Sleeve and you’ll see that this type of connector has an extra ring carved out on it that a standard mono 1/4-inch cable (like the ones normally used for guitar) lacks. See the pretty pictures in Chapter 3.

Very Important Note: if you want to run balanced signals, please use the XLR

GUIDED TOUR

jacks to connect the Studio Modeler to the rest of your system. The 1/4-inch connectors are set up to run strictly unbalanced. And what, pray tell, happens when you plug a mono balanced 1/4-inch TRS mono cable into the “stereo” out of the Studio Modeler? Well, the middle of the stereo field may disappear, or if you’re less lucky, the right channel may go AWOL altogether —pretty scary! So for balanced hookups, be sure to use the XLRs.

29. –10dBV Unbalanced 1/4-inch Out Right/Mono – Mono Out unless

something's plugged into the Left/Stereo Out, in which case you’ve got the Right Channel here.

30. +4dBu Balanced XLR In Left

31. +4dBu Balanced XLR In Right

32. –10dBV Unbalanced 1/4-inch In Left/Stereo – With a 1/4-inch unbalanced

cable this is the left input. To connect the Stereo Effects Send of a POD Pro or Flextone II to the Mod Pro, use a 1/4-inch TRS cable to connect to this input.

33. –10dBV Unbalanced 1/4-inch In Right/Mono – Mono In unless something's

plugged into the Left/Stereo In, in which case it's the Right Channel.

Audio Hookup Options

Note that you’ll want to get the best cables you can afford. Although we’d avoid claims that the cables are packed with Australian air or any such audiophile voodoo, good cables can make a difference. Really. And if you’ve got one of those setups with five different adapters plugged into each other to make the gazinta-gazoutas* match up (and we’ve been there, believe me!), we’d strongly suggest actually going out and buying or

building the correct cables. But it’s just a suggestion....

As you may have noticed in the Guided Tour chapter, Mod Pro’s back panel has a extensive (and possibly confusing) array of jacks you can plug stuff into (aka I/O). To attempt to help you along, here are diagrams of some typical hookups:

Basic Operation: Selecting a Program

Selecting a Program

There are two methods of selecting a program:

First, you can dial it up from the Program Select knob. Remember that the Program Select knob is ‘velocity sensitive’. The faster you spin it, the further it jumps, so if you

need to get from program 1 to program 99 in a hurry, just twirl it quickly. A slow spin moves you one program at a time.

If you’re using MIDI with the Mod Pro, send a MIDI Program change message from any MIDI controller to change the program. And because we were thinking ahead, you can actually call up the basic models as Programs, giving you a total of 115 available programs. See the MIDI Program Change Chart in the Appendix.

Editing a Program

Just call up a program or select a model with the Model Select knob and start twisting and tweaking. You can tell that you’ve edited a program by the hypnotic, slow flashing of the Save button (just don’t stare at it for too long, or you may start clucking like a chicken).

Tap Tempo and Speed/Tempo Calculation

The effects in your Mod Pro vary (or modulate) some element of the sound in time. The different effects modulate different things, including volume, frequency, pitch, phase, and stereo placement. One of the handy features of the Mod Pro is that you can set and display the speed/time of this variation in a number of ways.

Setting Speed/Tempo

When digital effects first hit the market back in the late 70’s, long before Tap Tempo hit the scene, calculators and stop watches were standard issue in most studios. Engineers would calculate the correct speed value in hertz for the tempo of a song by dividing the tempo by 60. This would give them the 1/4 note value, and from there they could calculate all of the wonderful possible rhythmic divisions like a dotted 8th or a 1/2 note triplet by using a division table like the one here:

Basic Operation: Tap Tempo and Speed/Tempo Calculation

1/4 Note Time Division Table

Note Value Divisor Note Value Divisor

Whole Note 4 Dotted 1/8 .75

Dotted 1/2 3 1/8 Note .5

1/2 Note 2 Triplet 1/8 .333

Triplet 1/2 1.333 Dotted 1/16 .375

Dotted 1/4 1.5 1/16 Note .250

1/4 Note 1 Triplet 1/16 .167

Triplet 1/4 .667

Fortunately, for the math-impaired, Mod Pro lets you bypass the math and just press buttons. It’s also important to note that many of the effects available in the Mod Pro did not originally allow the user to dial in any kind of tempo relationship. Most only had a speed control which went from slow to fast and back, making it especially tricky to match the speed of the effect with the tempo of the song.

Setting Tempo in BPM

1. Press BPM to see the tempo expressed as beats per minute.

2. Tap a tempo with the TAP button. (Tap on the 1/4 notes along with the music

that you’re adding a Mod effect to.) Or, use the Speed knob to adjust the current tempo.

3 • 5

3. Press the NOTE button as needed to select the note division you’d like for your Mod effect.

You can also set the speed/time in Hertz:

Basic Operation: Tap Tempo and Speed/Tempo Calculation

Setting Tempo in Hertz

Hertz (abbreviated Hz, so we don’t have to type quite so much) is a unit used to describe how often an event (say an Opto Tremolo sweep) happens. 1Hz is equivalent to one cycle (or sweep) per second, just in case you cared.

3 • 6

1. Press the Hertz button to see the speed expressed in Hertz.

2. Use the Speed knob to set the Speed in Hz. The Speed knob is also velocity

sensitive. Twist it quickly for coarse adjustments, and slowly for finer adjustments. You can use the Tap Tempo button for quick changes.

Hertz NOTE BPM

Now let’s talk a little bit about the Tempo display and its related buttons, since that’s where you’ll get a lot of your information about what’s going on. This display shows you the tempo in either Hertz or in Beats Per Minute (BPM). The buttons underneath it let you determine which of those two options you get, as well as select what rhythmic value you want the Mod effect to have. Bare in mind, though, that we’re not trying to force you into anything – if you don’t want to have a specific note value for a tempo, just press the Hertz button and use the Speed knob to dial up a value and ignore the whole BPM/note thing.

But, just in case you do want to do something cool with note values, here’s an example: Let’s say you’re writing a new Drums’n’Bass goth hit, with the leisurely tempo of 183 BPM. Let’s also say that you want the sample of your cat sneezing that you’re using as a snare to have a synced Mod sweep of a quarter note triplet. There’s no need to get out the calculator (or boot up that special piece of software you have) to figure out what the Hertz value would need to be. You simply press the button labeled “BPM”, turn the Speed knob until the display reads “183” and press the Note button until “

 3” is lit,

and you’re there. If your curiosity gets the better of you (or you’re working on the project with a friend and he needs to know ’cause he hasn’t bought his own Mod Pro

Basic Operation: Global (Speed/Tempo)

yet) and you decide you really need to know what the Hertz value is for that, just hit the Hertz button. Ta-da! The display switches back to Hertz, and you haven’t even had to think about that math stuff.

Sweep Reset

Another of Mod Pro’s cool features is the ability to reset the start of a modulation sweep by just tapping the Tap Tempo button once (tapping it twice, of course, recalculates your tempo). This means that you can control where the downbeat of a particular effect occurs.

Global (Speed/Tempo)

Global Speed/Tempo determines whether models and programs will load with their stored tempo or ignore that and use a Global Hertz or BPM value. Just press the Global button to toggle it on and off.

Hint: It’s on when the button is lit.

Set Expression Pedal

Pedal Assign mode lets you create two different versions (kind of like 2 snapshots of the front panel controls) of a program and morph between them with an expression pedal (like the Line 6 EX-1) connected to the 1/4” jack on the rear of the Mod Pro. This is great for controlling single parameters on the fly like the wet/dry mix, or exploring more radical soundscapes like adjusting Feedback and LFO Shape on the Dual Phaser model. The expression pedal is a key performance tool for both live and studio work. You can also do the same thing via MIDI using MIDI continuous controller # 4.

If you’re one of those types who’s used to the way an Expression Pedal works with the Line 6 MM4 Modulation Modeler stompbox, you’ll want to listen carefully. The Mod Pro works a little differently, but the concept remains the same. You may also want to check out page 15 in this chapter which describes the intricacies of the Pedal Update Mode options. But for now, here are the basics:

Basic Operation: Set Expression Pedal

1. Make sure that your EX-1 is plugged into the correct jack on the back of your Mod

Pro. From Program Select Mode, press and hold the Global button and then press the BPM button at the same time.

2. With the EX-1 in the heel down position, set up your basic program (Model,

Speed, Depth, Tweak, Tweez, etc.).

3 • 8

3. Move the EX-1 to the toe down position and set up a variation on the same

program (note: you can change any knob but model).

4. Move the EX-1 from heel to toe and back while feeding a signal through your Mod

Pro so you can make sure that the program is working the way you want.

5. Store the program (if you like what you’ve done and want to keep it), or press BPM

and Global at the same time. Either one will exit Pedal Assign mode. If you decide that you’ve made a bad decision (like the time you had one beer too many at the Mousetrap Dancing Festival), just press MIDI/Sys, and it will cancel everything you’ve done in Pedal Assign.

Basic Operation: Compare

Compare

Wonder exactly what edits you’ve made? Do you want to get back to the original program settings? Did you increase or decrease the Tremolo Depth and now wonder what it was when you started out? It’s easy to tell! Whenever you’re editing a Program, you’ve also got some handy Compare information available. Just look at the Program display while you turn a knob. You’ll see that when you turn any knob to edit the program, one or more dots in the Program display will turn on, depending on whether you’ve turned the knob up or down versus the saved settings for the Program. As illustrated by the images below, there are three possibilities: If the left dot is lit, the current value is less than the stored version of the program. If the dot to the right is lit, it’s greater than the stored version. If both dots are lit, the value matches the stored program. Pretty simple, huh?
