  1. Re:The list on PC World's 50 Best Tech Products of All Time · · Score: 1

    I'm not sure if the Ensoniq chip had volume envelopes or filters or LFOs, but if it did, I just wonder why they never used it on the Mac.

    No filters, but one oscillator in a pair can modulate the volume of the other:

    Oscillators

    The 5503 Ensoniq Digital Oscillator Chip (DOC) has 32 sound oscillators. Each of them are capable of making an independent sound. Two oscillators paired up are a generator. The paired generator arrangement is favored by most IIgs sound/music programs, because that arrangement offers greater flexibility with better sound quality.

    The DOC produces 8-bit waveforms, with a center line at $80 (128 decimal). Reserved for 'stop' is $00 or (0 decimal). If the sample value of 0 is encountered by a DOC oscillator, it will halt immediately and will not produce any more sound. The DOC also has an 8-bit volume register for every oscillator using a linear slope. The dynamic range of the DOC (the 'space' between the softest and loudest sounds which are produced) being approximately 42 dB.

    Each oscillator has a 16 bit frequency register, ranging from 0 to 65535. In the normal DOC configuration, each step of this frequency register increases the play rate by 51 Hz.

    Oscillator Modes

    When oscillators are paired as generators, four possible modes can be used. These four modes as termed, are listed below.

    1. Free (Free-run) (Loop) : The oscillator simply plays the waveform and stops. No interaction with it's 'pair' occurs.
    2. Swap (Loop) : Only one oscillator of the pair is active at a time. When one stops, its pair starts immediately.
    3. Shot : The oscillator plays the waveform and if it reaches the waveforms end without encountering a zero, it starts over (loops) at the beginning.
    4. Sync (AM): One oscillator of the pair modulates the volume of the other paired oscillator with the waveform it's playing. Unique and very effective. But, not commonly used.

    As for why this chip never found its way into a Mac, you can blame the Beatles:

    Though including a professional-grade sound chip in the Apple IIGS was hailed by developers and users both, and hopes were high that it would be added to the Macintosh, it drew a lawsuit by Apple Records. As part of an earlier trademark dispute with the record company, Apple Computer had agreed not to release music-related products. Apple Records considered the inclusion of the Ensoniq chip in the IIGS as a violation of that agreement. Though the IIGS was allowed to keep the Ensoniq, Apple has not included dedicated hardware sound synthesizers in any of its Macintosh models since (though of course, third-party products exist).

    you could theoretically demux up to 8 channels (with 4 voices per channel)

    According to Wikipedia, the chip did indeed have 32 channels.

    8*4=32. I think there's some confusion here over terminology. Each of the 32 oscillators on the Ensoniq 5503 counts as a voice. These get dumped into one output channel by a stock IIGS for mono output, but they can be demuxed by relatively simple circuitry into as many as 8 channels (though 2 was more common, for stereo output). "Voices" refers to the on-chip oscillators, while "channels" refers to analog outputs that drive speakers.

    How do you figure that when the C64 had no 80-column display capability (add-on or otherwise, AFAIK), no provision for adding more RAM (my IIe was bumped up to 1 MB at one point, and I had AppleWorks documents that used most of it), and a floppy drive that was almost as slow as the cassette recorder it was supposed to replace? An Apple II with nothing in the expansion slots may have only been comparable to a Commodore 64, but the slots let you add on whatever capabilities you needed--more memory, a faster processor, better graphics and sound, more storage (including SCSI and IDE hard drives), etc. That, in turn, was what let you get useful work done with it, which elevated it beyond "toy" status.

    Odd that the left out the IIGS and IIc Plus, though, while they listed the other models. The IIc Plus wasn't on the market long (don't think I've ever actually seen one myself), but the IIGS was a big step in capabilities that competed with the Amiga and Atari ST on their own turf, yet was nearly 100% backward-compatible with all of the Apple II software already available.

    With a train or (more likely) flight, you'll need to rent a car at your destination to get around...figure on at least $25-$30 per day in most cities for a midsize car.

    I can drive from Las Vegas to San Diego (~330 miles, about a third longer than the ~240 miles from DC to Pittsburgh) in about five hours on one tank of gas, which is maybe $35-$38 at the prices I've been paying lately. Las Vegas to Phoenix (~270 miles) leaves me with about a quarter-tank when I get there. Unless you're driving an old tank of a car or a full-size pickup or SUV, I don't see how you're going to burn through enough gas on a day trip to exceed the cost of airfare (or in the small handful of places that offer it, train service).

By the way, his wife Diann, also a moonbat activist, serves as executive director of the National Coalition to Abolish the Death Penalty -- which makes you wonder what else the Rust-Tierneys have been up to.
