    Is ARIA 64-bit ready now?

    I've read in the Steinway manual that the ARIA engine is 64-bit compatible but it doesn't go into much detail about it.

    Is the Steinway/ARIA ready to take advantage of >4 gigs of ram in standalone mode on OS X 10.5 (Leopard)?

    Hi

    This is a hot topic, and requires some bit of explanation.

    First, Garritan Steinway runs perfectly on Leopard.

    Secondly, on OS X there is currently only ONE 64 bit aware AU host, an its AULab (which is really only a developer tool, not what you call mainstream). So safe to say that only Standalone Samplers can take advantage of the > 4GB virtual address space, which is what your question is about.

    Now the Steinway Aria Standalone Player only requires a maximum of about 650MB of RAM at any moment (since it uses intelligent RAM recycling while streaming), So there is no advantage in having it seeing more than > 4GB at this point.

    As you might be aware, Apple has given all developers a shock by stopping support of Carbon UIs on 64 bit Leopard. All developers that want to provide totally native 64 bit apps under Leopard need to switch to a new programming language (objective-C) for everything linked to graphical user interfaces.
    There was a now famous discussions about Adobe's view of the issue this past weekend:
    http://blogs.adobe.com/jnack/2008/04...hop_lr_64.html

    However, this is not such a big deal for Aria, since it doesnt have tons of legacy UI code to modify, in fact, we can now announce that we are currently alpha testing such a port of our UI libraries, and we plan on having a fully OS X 64 bit version of Aria in an update soon.

    On a side note There is no such "issue" under 64 bit versions of Vista and XP, which are fully "64 bit native" in the shipping Steinway 1.0

    Hi David, thanks very much for your detailed reply. I know about the issues that developers are facing with Apple pulling the rug out from under you at the last minute regarding the Carbon/Cocoa frameworks. Steinberg posted a letter last year detailing the issues faced by having to port their code over to Cocoa for 64 bit compatibility.

    You said that the Aria Steinway engine uses about 650 mb of ram at any given moment, does that mean that it won't benefit from >4 gigs of ram? Or will it benefit if its available? Is it possible to load an entire instrument (one perspective) into ram on a machine with a lot of it?

    1 GB = 1024 MB, so 650 MB easily loads into a machine with 4 GB (or even less) of RAM.
    The way you would benefit from > 4 GB of RAM is if you had lots of other VST running and you needed 650 MB free for the Aria Steinway. For example, if you had Kontakt running and eating up 3.5 GB, then you wouldn't have enough RAM left to load the Steinway into RAM.

    Hello

    As a standalone, Garritan Steinway would not benefit from the > 4GB of ram in x64, however, theres more to x64 than improved Virtual Address Space! The second most important feature of intel based x64 platforms is the doubling of registers which really allow for even more optimization in both compiled code and hand made assembly (Which i do indulge into in occasion )

    Now not to say that Aria is "locked" and cant used more than 650Mb/1Gb! On the contrary.
    Its just that this particular library doesn't need more to shine. However the other Aria based libraries in the pipes (some of which are multi timbral will love it!)

    Also, as tfishbein82 mentioned, as a plugin, Garritan Steinway in conjunction with a host, would definitely benefit from breaking the > 4GB barrier.

    Well kudos on developing what seems to be the 1st true 64-bit sample playback engine for Windows. Don't know if this is the right place to ask this more general question, but is there a full blown sampler product on deck for those that want to sample their own pianos and instruments? And how about library conversion tools for those who might author in Giga or NI?
