Remembering Keith Barr, Founder of Alesis, Lost Last Week

Monday, August 30th, 2010

I was stunned last week to learn of the death of Keith Barr, the founder of Alesis and a beloved, legendary engineer of music technology. He was 61. An analog engineer gone digital, he led the charge to make digital reverb and studio recording affordable, and even after his Alesis years continued to be one of music’s great engineering minds.

Our condolences to Barr’s surviving family and to the countless friends and colleagues in the music industry and beyond.

Our friend James Grahame, Retro Thing founder and himself an engineer (via Reflex Audio and others, shares his memory of Keith with us:

Keith Barr was a musician’s engineer – his chip designs were all about sounding good rather than padding out spec sheets. A case in point is the Spin Semiconductor FV-1 reverb IC he designed in 2006. It uses a cheap 32.768 kHz crystal that you’d usually see in a real time clock circuit., generating an ADC/ DAC bandwidth of only 15 kHz. He commented that you could run the device from a 48 kHz clock, but you’d simply chew through delay memory faster without dramatically increasing the quality of the audio.

He also gave back to the engineering community by writing ASIC Design in the Silicon Sandbox: A Complete Guide to Building Mixed-Signal Integrated Circuits, in which he core dumps everything he’s learned about mixed signal chip design (including a business tips). The Spin FV-1 was designed at the same time he was writing his book, and it brings many of the ideas he writes about to life in stereo. In fact, the Spin Semi site is filled with stuff that’s usually kept inside R&D departments. The chip is extremely well documented with all kinds of useful design philosophies, code snippets and ideas hidden away in the knowledge base. I was stunned by his willingness to share his secrets, and by his almost childlike glee when someone did something unexpected with them.

A brief timeline:

  • 1949: Keith Barr is born; spends teen years working with electronics and science
  • 1973: Barr co-founds MXR Innovations, maker of a renowned line of pedals (hello, Van Halen)
  • 1984: Barr founds Alesis Electronics in Hollywood. Barr focuses on engineering.
  • 1985: The XT Reverb, created by Barr, is Alesis’ first product, and a landmark in making digital reverb accessible for the first time at US$799. It’s closely followed by the MIDIverb.
  • 1987: Alesis makes a name for itself in sequencers (MMT8) and drum machines (HR-16), teaming up with Marcus Ryle (later founder of Line 6).
  • 1987-1991: Barr conceptualizes a compact pro studio recorder, powered by digital tech. The result, released in 1991 as the ADAT, transforms the world of digital recording. (George Petersen for MIX points out this takes the price from Sony’s offering at $150,000 to the ADAT at $3995.)
  • 2000: Barr is behind the Andromeda analog synth, arguably the instrument that helps launch a resurgent interest in new analog synths. He also uses his brilliant use of economy to produce cheap, fun instruments with gestural control, starting with the AirFX and 2001′s AirSynth.
  • 2001: The victim of a changing business (and waning demand for ADAT), Alesis files for bankruptcy and is acquired by Jack O’Donnell, resulting in its reorganization as part of Numark. Barr leaves Alesis.
  • 2002-2010: Barr goes on to innovate in integrated digital chip design, as founder and President of Spin Semiconductor. He continues to create ground-breaking designs, shares free DSP code, and literally writes the book on ASIC design for sound. Spin carries on this legacy of affordability with ASICs combining extensive processing features in single, affordable boards..

Barr remained focused on the future up to his death last week; while he cut his teeth on tube circuits, he had recently led the industry in exploiting ASICs for musical purposes. (ASIC stands for “Application-specific integrated circuit”; by building circuits specific to a purpose, they’re inexpensive, efficient circuitry tailored to a specific purpose, like audio processing.)

Spin’s own description of Barr sums up his vision:

Although an analog engineer at heart, he designs computer architectures, the most recent of which is the FV-1 processor (Spin’s first product). Keith sees ASIC design as the next step in electronics engineering, and designs all of his circuits from the bottom up, from the transistor level.

I hope that Barr’s designs will continue to have a future in production, and that we can bring more news soon.

Rant – Congratulations, Apple: “Syncing” Music Now Means “Using iTunes”

Tuesday, November 3rd, 2009

Photo (CC) Tim Douglas.

Critics frequently attach the phrase “lock-in” to Apple’s iTunes Store – iTunes – iPod/iPhone combination. But, in the post-DRM age, what does that mean, exactly?

First, you have to recall that while for many of us the manual drag-and-drop music management is appealing, it isn’t so for many average consumers. They want sync. That means that music will be stored in iTunes and synced to Apple devices and nothing else. Apple is serious about locking you to their store and their devices, enough so that they frequently update their software with special keys that prevent the use of devices. iTunes is “free,” but Apple determines which mobile devices you can use and which you can’t. And Apple has gone after anyone who dares give you the ability to use your own music software or own devices, including efforts (ironically) to make their iPhone and iPod work with Linux and open source players.

These efforts don’t protect the music or prevent privacy – they protect users of Apple’s software and mobile devices from using anything but Apple’s tools. Yet Apple has used the Digital Millenium Copyright Act to take legal action over anyone who dares to even talk about how to use legally-purchased music and hardware:

OdioWorks v Apple

Perhaps suspecting their case was too thin to defend, Apple eventually backed off that particular claim — after, says the Electronic Frontier Foundation, “7 months of censorship and a lawsuit.”

Apple Withdraws Threats Against Wiki Site

But the software and hardware locks are unchanged. And Apple has won, in my view, an even more important battle: they have a monopoly over mindshare.

Here’s an example from a recent review by Gizmodo of the Android 2.0 mobile operating system from Google, as implemented on the Verizon-distributed Motorola Droid. They have some fair points about Android’s maturity and strong and weak points. But note what they say about music sync:

The only way to get your music and videos on the phone is to manually drag and drop the files. There is no syncing, no easy way to get your music library onto your phone. How are normal people supposed to figure this out? Verizon reps actually joked about how putting music on the Droid is sure to make for a lovely Saturday afternoon. What. The. Shit.

In fact, this is technically accurate, to my knowledge, only if you’re using iTunes. That incompatibility is engineered specifically by Apple. It’s a “feature”: other vendors could make other devices sync with iTunes, but Apple engineers regular updates to prevent them from doing so. In fact, while Apple was conceding defeat in its efforts to censor the Web over its iTunes lock, it was simultaneously busy blocking the Palm Pre from working with iTunes. This should be especially sad to long-time Mac watchers, who saw a Mac community railing against Microsoft’s effective office software and operating system monopolies in the 90s. Those Mac historians should also recall the early development of iTunes and shareware predecessor SoundJam, both of which worked with a variety of hardware. Now, some members of the same Mac community cheer market share numbers and anti-competitive practices by Apple.

But, engineering aside, it’s really the mindshare battle that’s most impressive. Gizmodo, in saying the Android “doesn’t sync,” really means that it “doesn’t sync with iTunes.” And given iTunes’ massive market share, Gizmodo is not alone – I’ve seen similar complaints from other press outlets and, anecdotally, many, many users.

In fact, Android sync is supported by a variety of applications. In my tests, it works with the open-source players Songbird (Mac, Windows, Linux), Banshee (Mac, Linux), Rhythmbox (Linux), Winamp (Windows), Media Monkey (Windows), and yes, even Microsoft’s own Windows Media Player. Microsoft may restrict the use of its Zune media player, but ironically its music playback software is far more open than Apple’s.

androidbanshee

Banshee automatically syncs my Android on Ubuntu Linux. And yes, even normal people, or “human beings” as the Ubuntu folks like to say, can use this. I find myself cursing at iTunes, and have even found this easier.

By “sync,” incidentally, I mean automatically – it’s no harder to use these applications with Google Android than Apple’s iTunes and iPhone/iPod. I personally find most of them more flexible and intuitive than iTunes. And I can show someone in a couple of minutes how to manage their device via the file system, too – even “normal people.” (I definitely don’t count as “normal,” so no argument there. But presumably “normal people” can learn to use the Mac Finder, right? Apple certainly argues they can – then locks users out of that tool when they connect an Apple mobile player.)

This is not a pro-Android argument, despite the screenshot. Any music player or phone that supports normal disk mounting will work the same way.

Why should all of this matter to musicians? The reasons monopolies are a concern in the first place has to do with pricing, and media monopolies add to that control of culture and speech. Even if your music isn’t distributed through iTunes, pricing and consumption patterns, and even the kinds of music people listen to and where they discover it are now being deeply impacted by Apple. Apple, in turn, by convincing users that there are no other options and engineering interoperability out of their products protect that control, just as digital music is growing by leaps and bounds. (For statistical evidence of the resulting trends, see today’s other story, linked below.)

I spoke to the Electronic Frontier Foundation’s Senior Staff Attorney Fred von Lohmann in April about the paper-thin (literally) arguments from Apple, when Apple was trying to prevent websites from talking about the database lock between iTunes and mobile devices:

All Apple has told us about this is in the letter they sent to us in December, as posted on the website as an exhibit to our complaint. Apple simply cites the fact that the iTunesDB page authors said that the obfuscation mechanisms used to create the iTunesDB has “may reside” in the FairPlay DRM code.

…The important thing here is that the iTunesDB pages were simply discussions about what might need to be done to reverse engineer the iTunesDB hashing. There was nothing to indicate that the efforts had succeeded. So even if understanding the iTunesDB hashing mechanism somehow magically unlocked all of FairPlay (which would seem to be far fetched), nothing on the pages suggests that the authors were anywhere near that goal.

Note that at the time, the EFF did not claim Apple lacked the right to make these kind of locks. The EFF told CDM at the time, “They have every right to do – to try to block it. Apple can certainly try to block it. What they can’t do is use inapplicable federal law to use legal threats to get them to stop.” And Apple backed off those claims.

The issue is whether you should invest in a product that limits your freedoms to use it. And the issue for musicians is whether this kind of a behavior from a company with an effective monopoly is limiting the potential power of digital music listeners in the future.

This is not to say that there aren’t reasons to choose to use an Apple device or its iTunes software. As reader “low resolution sunset” says in comments on the previous story:

This is pure conjecture: but I tend to think that slick interface design, trust, and loyalty for the Apple brand identity is what’s winning them the dominant market share of downloads.

Indeed. So, why not rely on that design, trust, and natural loyalty? Why force loyalty through engineering? And even given these qualities, isn’t there a danger when one company becomes so dominant that people don’t so much as consider alternatives? What’s to keep Apple competitive on good design if they have no competitors?

I certainly can’t answer those questions. And in the meantime, I’m looking to other alternatives, alternatives that have made me quite happy.

LP 45th Anniversary Congas, Bongos And Mambo Cowbell

Friday, September 4th, 2009

Having forged a legendary reputation, LP is now into its fifth decade providing scores of world-class percussionists and aspiring players alike with the industry-standard choice. Martin Cohen’s company produces a vast catalogue of instruments that are both durable and widely regarded as the real deal.

Build

This limited edition 45th Anniversary range offers the player a choice of an 11″ quinto, 11 3/4″ conga and 12 1/2″ tumba with a matching bongo set, mambo cowbell and cabasa (not included in this review).

The congas stand 30″ tall and their shape is inspired by LP’s original design dating back to the ’60s. They’re constructed from kiln-dried ash wood with a slim reinforcing layer of fibreglass applied to the upper part of the inside of the drums. This serves to add strength while focusing the tone.

“You could play these for hours and not feel like you’ve been whacking a table top as with some bongos – courtesy of the heads which give and take with every stroke.”

The congas and bongos are beautiful, with a rich dark blue gloss finish highlighting the wood grain patterns underneath. With brushed nickel hardware throughout, heart-shaped tension plates and LP’s Comfort Curve II extended collar rims, they certainly look a class act.

All of the instruments sport the company’s brand new ‘tribal’ logo, and on the congas and bongos the logo’s Silver Sparkle finish contrasts beautifully with the blue grain swirls. Matching chunky carrying handles make carting the congas around easy and they all have mounting collars which can be situated on either side of each drum if you decide to stand-mount them.

The inclusion of LP’s minimalist but highly effective ‘Pro-Care’ rubber protectors on the tension screws means that even if you happen to knock the drums against each other that finish won’t get ruined.

A unique and highly practical touch is found on each of the three drums in the shape of an integrated, screw-tightened mounting bracket. This allows you to attach a variety of auxiliary items such as bells, blocks, splashes and, perhaps most usefully, microphones! You could then wail away as hard as you like in the knowledge that, even if you move any of the drums while playing, you will always get a consistent mic level.

The mambo cowbell is a large, affordable bell that would work equally well in timbale or drum set situations. It has an easily adjustable mounting bracket that is especially kind on the fingers. When mounted and gently finger-tightened, the bell is reassuringly steady and didn’t budge even under heavy abuse.

Hands on

The congas were beautifully responsive and, even when played placed on the floor, had a deep, full sustain in the bass frequencies; mid-tones and slaps were easy to elicit and the feel of the durable but highly responsive heads was a pleasure. The addition of the thin fibreglass internal coating did seem to make a difference and possibly tightened up the tonal palette, producing a highly musical set that you will be sure to be impressed by.
