Then why not just run them in parallel like Digidesign does with TDM? You'd probably have to bounce in real time, but other than that...

Note that I have no idea what I'm talking about, if you haven't noticed - I'm just musing out loud.

We can fairly saftley assume, I think, that by the time this all comes together that there is a good chance of a 64 bit os, 64 bit VI and 16 GB 8cpu 3 or 4ghz Macs all working together with Logic and Cubase inside 12 months.

It's interesting that there are two opposing lines of hype going around, which might be telling. One was the graphic behind Steve Jobs at the Apple Developer Conference with 64 bits shouting all over the place, when they announced... Leopard? (This cat thing is getting a little naff by now; I can't even keep track of which ones Tiger, Panther, and Jaguar are at this point.)

The other line of hype you hear a lot is "what does the mainstream user need 64 bits for?" That makes me wonder, because I read it a lot and it smells like "positioning." [:)]

Cakewalk and Steinberg were hawking 64 a couple of years ago (but they aren't really doing that now), and some audio hardware companies have 64-bit drivers, but in general I haven't heard software companies tout this as much as you'd expect if it's really close on the horizon.

Meanwhile the price of the RAM these machines are using is a major stumbling block.

For the 2X dual cpu machines, Apple already has double bandwidth bus architecture, in short, sufficient bus for each CPU core... naturally as I said one would expect that they expand the bus architecture to accommodate the extra cores.

RE hard drives: if the drives are slow loading just buy more drives! if you have 10 X 20 gig drives on a PCI card, 128 GIgs is going to load REAL fast don't worry. Just distribute the instruments over the drives.

RE multi cpu efficiency: since apple and windows are now on even processor playing field, I think the competition will now continue to be viewed from a perspective of efficiency of the OS, and this will come down to core tasks such as management of multiple cores etc, at least to a significant degree. In other words I think we can say that those types of issues will *at least* be more or less properly looked at in both camps.

Of course it goes without saying that it is the overall design of the machines that is what produces the results, including the OS. In that I think proper investment will be made largely because of the fact that competition is a big part of the game and they have to compete with regards to efficiency on both platforms on more or less similar hardware (at least cpu's).

I don't know about PC hardware but Apple has already taken care of the bus issues with regards to present machines, they have AMPLE bus architecture for both the multiple core cpu's and RAM access as well as hard drive access. I assume future machines, with more cores, will automatically take this samee design principle, which is inescapable when dealing with multiple cores, into account properly since they are already doing so now, and obviously realise the benefit of it. OF course there may be limitations in machine design, but since it's obvious that multi core is the way the industry is going, it's probably fair to say that mother board manufacturors and the like are already well aware of and planning for the likely futures of 8 cores and so on.

Just my thoughts on it anyway.

There will always be a bottleneck somewhere: either buss speed, processor speed, available RAM or disk throughput. And as soon as computers get fast enough to run 800 voices with 50 Vienna Instruments on a single computer, I'm sure VI2 will be announced. [;)]

But this makes me want to upgrade my system, at least to a Core2Duo with an upgrade path to a quad.

Same here.

Hi Miklos,

The VI's appear to load at between 15% - 25% of the rated transfer rate of the hard drive. Also when a number of drives are utilized these figures do not scale at anything like 100%. I can currently load up a single 2GB file into RAM (from a 4 disc SATA raid) in a few seconds but to load 2GB of VI stuff takes a number of minutes.

The net result is unless there is a significant speed increase (x20) in speed of file transfers of the VI type switching between songs would become impossibly slow with RAM amounts approaching 100GB.

However what would speed the whole process up immensly (even now) is if the VI's (when used within a host) could scan current RAM to see what was already loaded - like the "keep common samples in RAM" function in Logic.

.... and what would be even better if a similar function could occur even if the song you were opening was replacing one that was being closed.


Julian.

Here's a thought (and pardon if it's not reasonable):
In Digital Performer you load VI's into a "VRack" which allows you to switich between sequences in the program with no waiting. Of course when you close or open up another file with say, another film cue and Qtime file etc., everything reloads and you sit and wait.

What if the program itself allowed a VRack type host to remain open or at least allow samples to remain in ram (as mentioned above) untill you actually quit that part of the program?

This may be of no help, but I just thought that I'd share my brilliance with you in case there is an application for it in your case....!

I was finding that when changing projects it was taking 15 minutes to load samples and as soon as I wanted to switch projects they were all being dumped and I was having to load again. I am using FX-Teleport as a host and this is where my genius comes in. I load my whole template for each PC into Forte on my DAW, but using the LAN version of VI. In other words I do exactly the same thing as loading in Nuendo, but instead I'm doing it in a VST host. Now the clever bit. When I open my project I load exactly the same samples, but this time using Nuendo as a host. Of course VI knows that these samples are already loaded into FXT so it doesn't load them again (actually it takes about an extra 79MB up). Now my template is up and running immediately, I can change projects, close Nuendo and all the samples are still loaded when I open the project up again. This means that I can change projects instantly and have all my samples available without loading. I just have to make sure that either Nuendo or Forte (or both) is open ay all times.

DG

Okay so basically you load all your samples outside of the DAW in a VST/AU host so they remain in RAM but you don't use the external host. Of course that begs the questin of why not just use the host program. Fotr me the answer is I have never been able to run Plogue outside without performance issues.

Do I undestand your idea correctly?

Loading in the DAW is much more convenient when it comes to mixdowns, using plugs etc. I can also have almost unlimited VST outputs, whereas using the Host I'm limited to what my hardware has.

Regarding performance issues in the host, as I don't have any MIDI input or audio outputs enabled there is no chance of a problem

DG

Right, of course.

Julian sounds like cpu will fix that eh?

Nick: why would OSX be 64bit in Leopard, with 64bit Apple apps coming soo after? Why would they bother if it wasn't the direction of the future.The fact is that 64bit is necessary for the coming years because of hard drive/storage and memory access. It's like people used to say why would you record in 24bit when you're mastering to 16bit! What a rediculous argument, yet people made it earnestly everywhere I went, but I always said you can't compare 24bit to 16bit even on a master.

I think that will help. When, for example, you are doing a Retrospect back-up and large files are being archived the data transfer rates are as much as a hundred times quicker than when the system, library and cache folders are being backed up when tens of thousands of files are being copied.

So the consideration with VI's is not only the RAM amount but the number of files (headers) and currently the sheer number of files requred - which is a direct by-product of the quality/flexibility of the library - appears to be the limting factor in load times.

So although many users (me included) want to load more VI instances and larger matrixes, once we head south of 10 GB's of RAM I suspect the limitatons will start to come from the drive/cpu access and load speed. I'm not an expert but it is possible CPU increases will help, alonge with I suspect further, VSL software evolution.

Julian

No question, Miklos, we're headed to a 64-bit world. Absolutely, 100%.

My only question is about the timing. It seems to me that we'd be hearing a lot more noise about it if it were just around the corner. So far I haven't seen a single press release saying "XXX announces 64-bit version of YYY."

You could argue that they're just waiting until it's ready, but most companies don't do that. They all sent out press releases saying they were doing universal binary versions, for example, even though they didn't appear for several months (and some are still appearing).

Remember, 10.5 will run 32-bit programs too.

And frankly, the old "run stand-alone version outside your DAW and access all the RAM you can eat" trick has me less excited about 64-bit computing.

Also, I'm not entirely sure the 24- vs. 16-bit analogy is all that à propos. 64-bit processing is unlikely to result in better sound, in fact it's not even a given that it's going to give us any more plug-in horsepower in all cases. What it will do is give us unlimited memory access.

Nick: it seems widely accepted and publicised that Vista is 64bit. AMD have their 64 bit chips, Core2 duo "64bit", which has been marketed as such, and there seems to be a considerable difference in speed over the last gen of intels, how much that is because they are 64 bit or for other reasons I don't know - and of course OSX has been 64 bit for a long time which is now going to be 64bit at the GUI level too. All this is widely known and publicised.

Miklos.

My hunch is that, from a marketing point of view, Apple would very much like to be able to announce 64bit - - versions of its Pro software applications (including Logic Pro) that can make use of as many processors as a machine has - - along with OS 10.5 and 8 processor core hardware. What better way to advertise the advantages of OS 10.5 - - and to give Apple a chance to sell pricey (e.g. perhaps "only" $399.50 for updating to "Logic Pro 64 Xtreme") updates? Whether or not such a time table is practically achievable is another question, but perhaps we will have some hints at MacWorld Expo in January. In the meantime, we have to hope that the price of ECC FB RAM starts to decline significantly.

Miklos, I think you're missing my point.

A 64-bit computer system has the processor, OS, *and programs* running at 64 bits. Without all three you still have a 32-bit system, and the last to fall will be the software. It will happen, but the question is when.

I think it's going to take a while.

Also note that right now Mac OS X is only 64-bit capable for programs that don't use its graphic interface - i.e. UNIX command line programs. As a practical matter for you ane me, that rule out every program on the planet.

Nick: I think I said, that Leopard will be fully 64 bit thoughh and that is not far away.

Ram prices will fall once people start buying more. People will start buying more when they can use it...

64bit apps will become the new marketing fad, because the cup manufacturers are making the chips, now it's going to be, this app is 64 bit this one is not. Properly written apps will surely demonstrate the difference even to modest users I think, well, that part is just a speculative opinion I admit.

64-bit versions have been available to all Sonar customers for two versions now, so... I'm not certain how that qualifies as not "hawking 64". I think for many PC users (at least this one) it's just taken as a given that it's available now (you don't see many headlines about features that have shipped a year ago). At least for me, it's just about the cost of upgrading to a new platform that's holding me back, but I'm saving my pennies...

There's a few links here about the state of 64-bit computing that are interesting, as well as the obligatory promotional stuff from Cakewalk and MS.

Thanks a lot James, that was a good link and very interesting.
