New Developments in Music Technology 218
jonerik writes "The Christian Science Monitor has this article on acoustic and electronic music technology, including a visit to MIT's Hyperinstruments lab, which has developed a series of Music Shapers; ball-shaped musical toys which are covered with 'a patented thread containing sensors that react to the way the child handles them. The child manipulates a preprogrammed "little seed" of music and helps it "grow" by the way he or she shapes it.' Also worth a read is this article (free reg required) on the Line 6 series of bass and guitar amp emulators, which do a pretty decent job of mimicking various amp or amp/stack combos; from a '53 Fender Deluxe to a mid-'60s Vox AC-30 to the sludgy murk of a '70s Orange stack. 'Line 6 uses a technology called modeling to measure the characteristics of a particular vintage amp, from the distortion of its original tubes to the resonance of its speaker cabinet. The company has developed a way to reproduce those measurements in a powerful D.S.P., or digital signal processing, chip that contains models of dozens of classic amps.'"

I mean, you only have to take a look at the synthesizer business to get an idea what I'm talking about.
Korg basically hired *one guy* to come up with all of the sounds used in their Triton and Karma synth workstations - and these are their flagship units!
When you're looking at something like a wah pedal that'll sell for under $149 or so, retail, when it's all said and done - how much are you going to pour into design research on it? Don't forget the fact that these things will only end up being sold mail order through musician's catalogs and at music stores. People won't be picking them up at their local WalMart or Best Buy store.
Right now, if I was a tube amp manufacturer, I'd probably try to maximize my return by recycling tried and true designs that I already kow sound good to most people. The majority of my buyers are either going to be A) younger kids who never heard the original design from 20-30 years ago anyway, or B) working musicians who are trying to replace their old gear that finally wore out - and would likely buy a new "work/sound-alike" of their old standby.
For something as cheap as a stomp-box or wah pedal though, I'd just have an E.E. throw together a cheap to build circuit that sounded "good enough" and go with it.

Korg has customer service reps regularly reading the forums these people post on, so they can't claim "We never knew these guys were out there!"
The fact is, they're on a pretty tight budget for R&D of these things, and most folks who try to make a living out of developing patches for synth workstations have to start their own businesses. Then, *maybe*, you'll get paid to work on one project for a synth maker - or maybe not. It's not like they're eagerly hiring on every talented patch-developer they can get their hands on....

Most amp models neglect the key - overdriving the tube power amp and driving the output transformer into saturation. Any tube amp designer worth their salt knows that you design an amp around the output transformer - that's where the sound comes from, not just the tubes.
I took my amp to a shop and wanted to buy a new set of tubes. I swapped out all their preamp tubes and wasn't happy. Then I swapped some power amp tubes - WOW did that make a difference. There was more flexibility in the tone with power amp tubes than with preamp tubes.
Many amp models only take the preamp stage distortion into account. They neglect the power amp stage distortion, which is where the key to the sound is. This is where the guitar becomes a living breathing thing.
The new Marshalls don't have near the same sound as the old 60s models. I heard a '69 plexi and can confirm that they have a unique bark that no new Marshall or amp modeler has yet to approximate.
IMO the acid test of amp modellers is the "Boogie" model, aka "California" to avoid trademark infringement. My 1979 Mesa Boogie MkIIa still kicks their digital ass, nothing comes close to the real thing. I'm primarily a keyboard player but I can still hear the difference. The one that does come close is Tech21.
An interesting note is all the traditional amp makers - Marshall, Vox, Fender - now offer a modelling amp. Mesa Boogie wisely chose to avoid this fad.

Absolutely. Also power amp tubes, typically 6L6s in the US, give a much smoother tone when overdriven. The 12AX7s you find in preamps sound at once thinner and more jagged in saturation. I remember when I was young some company came out with a tube distortion pedal. I looked at the specs and it had a single 12AX7 inside. I figured it wouldn't sound good. When I did finally hear one I was unimpressed. I agree. But in the hands of a good EE the preamp can work wonders too. That was what amazed me about my hot-rodded Music Man. My amp guy rewired the hybrid preamp to squeeze every bit of solid state odd harmonics nastiness out of it, then drove the power amp enough to balance it with yummy soft serve 6L6 warmth. It was like a Boogie gone bad. I agree, although I've never been that big a Marshall fan. I've heard modified Marshalls that blew stock ones out of the water. Maybe you could get more of that bark with different cones. Some people also swear that EL34 equipped Marshalls sound warmer than 6L6 driven ones. I love Boogies. They are the only off the rack amps I really like for every day use.

First off: MIDI signal only sends information on pitch, note duration and attack velocity. Any other information is interpreted by the synthesizer (hard- or software) and produced as sound. It doesn't carry data about sound quality, that's up the the synth.
That said, if you play a melody into your imagined setup there has to be some point where the computer red-flags what you're playing, compares it to a staggeringly huge database of known melodies, markes it as copyrighted and cuts off all signal to your speakers. Problem is, there's no way for midi to measure tempo. I could play the same melody at two different speeds and the note relationship would look the same to the database. Melodies aren't unique, far from it. I could change the chords to anything and have something new.
The problem is one of fuzzy logic and it's a rather nifty catch-22. In order for a piece to be flagged as something you don't have the rights to play, the computer has to be rather lenient in its interpretation of what you're playing (because every live performance of anything will be slightly different). But as soon as that leniency is introduced into the program the results won't be accurate enough to tell for certain.
Besides, all this'll do will bring back the good ol' accoustic instrumentation, and personally, I say go for it.

Also, a lot of DSP-based digital effects equipment have been offering this technique for years. The problem used to be, and perhaps still is, the quality of the signal.

It requires some basic coding skills to really use it correctly, but it gives one person quite a bit of control over a whole performance. The basic idea is that you have a recorded sequence of notes in a computer, and whenever you hit a sensitive table with one of the batons, it activates the next note in the sequence. Also, the spot on the table that you hit changes the amplitude of the sound. So one person could ideally control a whole orchestra of sounds and keep the pacing as necessary.
Here's one website [emf.org] on the device. Google up more if necessary. And if you believe that computer-generated samples will never completely sound like the real thing, check out information on a program called Gigasampler, a revolutionary program which learned to read music samples from ROM instead of RAM, allowing for extremely large and complex samples, far closer than anything else I've heard so far.

In fact, with a good antialiasing filter, 16 bits @ 44.1 KHz will put you below the noise floor of all but the best amplifiers and cover the whole range of human hearing. Problem is, an antialiasing filter suitable for 16/44.1 is VERY tough to design without causing distortions in the range of human hearing. 24/96 is easy to develop a suitable antialiasing filter for.
Problems ensue when you are processing the data, though. If you process 16-bit data in the DSP with 16 bits of precision, then at every step in the processing chain you'll likely have rounding errors. Such errors accumulate.
For 16-bit data, I believe most people use DSPs with 24-bit internal precision at a minimum. For 24-bit DSPs, 32 is probably the minimum. I don't know what the likes of Line6's products use. A floating-point DSP would do VERY well for eliminating rounding errors, but those cost $$$.

Weezer used line6 equipment on their last tour. Both guitars and bass used Pod Pros. (One of their rack mounted units). They didn't use any amps. They said they a/b'ed the pods against amps and couldn't really tell the difference. In fact, they liked the pods better in some cases.
One of the main reasons for using the pods is that they got a much "cleaner" stage sound -loud amps are hard to control in the mix. This was essential for them because it was during their wacky tour where they played weird locations like bowling alleys and 7-11's -all small, uncoventional venues.
Personally, nothing has yet been able to replace a real amp for me...
Re:Weezer and Line6 (Score:2)
They probably don't record that way, perhaps using different guitars and amplifiers to get the sound they want in the studio. They really don't have any way to do that on stage, after all, changing guitars and amps during a song is a little difficult to pull off, so they use effects boxes to simulate what they would do in the studio.
I can see the real benefits of doing this type of thing on stage. Let's be honest here, you may be able to hear the difference, but how many people in the audience can, especially at the sound levels they get to listen at?
Line 6 POD (Score:2)
One of the neat things about it is that when you select an amp model, the bass, treble, drive, and other controls on the POD behave the way those controls would on the real amp.
Without having played through all of the different amps and cabinets that the POD emulates, it's hard for me to say how accurate all the emulations are. But the SWR model does sound a lot like my SWR amp, and the Ampeg model definitely seems to have the SVT feel to it.
The manual has an interesting description of all the different amps and cabinets that they modeled, along with some history of the companies and designers that produced them, and some of the well known bands and recordings that used them.
The SPDIF out (on the Pro model) and all the other in and out connections are really useful. If you play bass or guitar you should check one out.

I don't think you read the article or looked at the website. The idea behind these products is that the $300 Mexican-made Fender Stratocaster that you buy for your kids can sound like a $3500 Epiphone with a little digital tweaking. The kids are still playing real instruments--this product lets you expose them to instruments that most are way beyond most parents' budgets.

The Cyber-Twin (Score:2, Informative)
I HATE digital effects, and being what in people used to call a "shoegazer" band means I use a lot of effects. I'm always tripping over stomp boxes in shows. I'm also a die hard tube amp user, but I thought I'd check out the Line6 and see what all the fuss was about. It was a good amp, and I came REAL close to buying it. Sure, you could tell that it wasn't a pure sound, but it was a GOOD sound.
I didn't buy it however (can't really afford a new amp at the moment), and had to go back to playing through 1 amp.
Has anyone played through one of Fender's Cyber-Twin's yet? It supposedly reroutes the analog signal path to achive different amp sounds instead of digitally emulating them. I haven't had the chance to play on one, and I'm wondering how they sound in application.

Another tube & audio amp bigot... (Score:3, Insightful)
Line6 won the first battle (Score:3, Insightful)
Since the Line6 products at the time were cheaper, they sold better. Tube amp purists wouldn't touch either product, so it was left to those of us who either didn't care, or weren't irrationally biased against the fledgling technology. I guess to many people, any difference in sound between the products was worth the savings in buying a Line6. Plus, Line6 seemed to have the far superior marketing team. So while Johnson struggled to carve out their little niche, Line6 grew and flourished.
Now, unfortunately, Johnson has all but gone out of business [johnson-amp.com] (I believe they were a spin-off of Digitech, which is still going strong). I bought a J-Station [johnson-amp.com] about 2 years ago and have loved it as well. Again, I felt it sounded slightly better than the Line6 Pod, but then maybe I was biased for Johnson by then. It's too bad that they didn't have the marketing team to compete better and stay alive - as many of us here say, diversity and competition is always a good thing.
Other companies have been entering the fray in the last couple of years (Fender Cyber-Twin, etc), so certainly there is still some competition and great things to look forward to in the future. I'm just a little sad that I won't get to see what the Johnson engineers might have come up with next. Hopefully they're still working on similar things, either at Digitech or other companies.
One of these days I'll have to pick up a Pod (or whatever the Line6 equivalent is these days) just to add more sounds to my arsenal. Should be great.

Line 6 Guitar Port (Score:3, Insightful)
Now, of course, you can ALWAYS get a better sound in a recording studio with the real equipment, but you are going to spend $1000's of dollars doing so.
I wish I had had this thing before I bought my Mesa Boogied DC5 a few years ago. I absolutely hated that guitar amp! If I had had a Line 6 Guitar port, I could have experimented with amps and effects and determined long ago that I should have bought a Marshal amp. I know you can try them out at the store (and you still should), but the hours you can spend with the Guitar Port narrowing down the list of possible candidates is worth it.
Digital music technology has come a long way (and boy is it getting cheap). If you haven't checked some of this stuff out (especially the Line 6 brand hardware) you're really doing yourself a disservice as a musician.

Amp modelling is not new! (Score:3, Informative)
Good grief, where have you been? Pick up any equipment catalog and you'll find dozens and dozens of modeling amps, effect boxes, etc. In fact it's tough to find a multi-effect box that doesn't include amp modeling. You can get really good ones for $200. You can even get a guitar (Variax) with modeling built into it, so it can sound like it has single-coil pickup, humbuckers, acoustic, bass, you name it.
It's all very cool, but it's like Slashdot running a story about flash cards being an amazing new technology.
DSP amps are different, useful, but not perfect (Score:3, Informative)
I'm a guitarist and have used several of the DSP amp simulators. The untrained ear might not know the difference, but many guitarists definitely do. The amp simulators are getting better all the time, but they will always be simulators and not the real thing.
HOWEVER, these amps are so convenient that they can help a musician in other ways. Aside from the obvious size & weight issues, it's far easier to experiment with new tones when they're at your fingertips. That makes people more creative, if they don't get too sidetracked by having so many choices.
Also, DSP technology can create a lot of new tones that vintage amps can't. In this case we're no longer trying to live up to a classic sound, but we're creating something genuinely new.
Software-based plugins are becoming more popular. Companies like Antares [antarestech.com] and Art & Logic [artlogic.com] are creating some really cool software-based audio plugins.

Line6 Amps and Guitar (Score:2, Informative)
The PODs are fantastic, the new PODxt especially, but the proof's in the pudding. Almost every recently-recorded song you hear on the radio or on an album was probably aided with a POD. Engineers love it when I bring them in to the studio because they don't have to work hard to get a great sound that fits perfectly in the mix. I have only heard complaints about the gear on the Internet (go figure), and never from real live working musicians.
And the new Variax is great. At its current price point it is incapable of replacing a good vintage "real" guitar, but it plays just like any other guitar, and several of the models are dead accurate. The 12-strings are a little off (as would be expected), the banjo, sitar and other resonator models (dobro, tricone) are surprisingly great, and the Strat, Teles, and Les Pauls are unbelievable. And the guitar just feels good; it's not a geek toy that looks like a guitar, it's an actually decent guitar that just happens to do amazing things.
Put the guitar together with a new Vetta and you just spent about $3,000 to reproduce about $150,000 worth of vintage gear, much of which is more fragile and scary to gig with than the far less expensive Line 6 stuff. I don't work for these guys but I do not hesitate to recommend them to other musicians. If you actually play for pay, you can't afford not to check them out.
