When something is streamed from a hard drive it still must go into the system RAM to be able to be used.

Streaming is just a technology that allows audio/visual to be played/started even though its not fully loaded into RAM.

Hard drives are ONLY for storage, and in the case of PC's for a "pretend" RAM area. Even if the Audya is using a part of the hard drive for a pseudo ram (swap sector) technically it is still RAM, and the sampels are being streamed to there if there is no dedicated RAM space left.

Also interesting to note, not only does the Audya have USB 1, it also STILL uses the much older(read slower) IDE interface technology for the hard drive??!!

I would have thought it would be at least at SATA level. Much quicker transfer rates than IDE, and well suited to streaming.

so Nedim,

who's right? you or FCMUSICA?

Ganiek says USER audio loops DO stream from HD, NOT from RAM or ROM

he has AUDYA, he has OS 3.0 beta

so does this mean the PA2X is 6x more than AUDYA?

or is AUDYA 200x MORE than PA2x?

fun it is indeed :-)

I always sad, Ketron machines are built like tenks, by German engineers in WW2...hence
everything inside including the OS is since
Hitler Beta tested.

but those with OS 3.0 and AUDYA should know more than those without, wouldn't you say?

but this OS 3.0 may pose a SERIOUS problem...
as i may not have the time to choose from the THOUSANDS upon THOUSANDS of audio USER drum loops in my HD :-)

Frankieve, we were informed quite a while ago that, while the drum loops streamed, the guitar loops have to be loaded into RAM (but perhaps not the same RAM as is used for the sampler) because the HD couldn't stream that many simultaneous streams.

You see, while the drum track only needs the ONE stream at a time, for all the guitar chord choices you have the ability to make on the fly, the latency of coming off the HD would preclude that. I believe AJ told us quite a while back that the guitar loops are ROM (no matter where they are stored) and the drum loops are RAM.

I mean, if the guitar loops were streaming, there would be no problem having as many chord types as the chord recognition engine could know. But three simultaneous chord types was the maximum that Ketron could achieve. And that had to be from RAM. When you think about it, having all those chord choices INSTANTANEOUSLY available requires hardware speeds. In fact, from some of the reports we have got about glitchy timing occasionally between style divisions, especially Intros, it seems the poor thing is having a hard enough time just streaming ONE stereo file in realtime when asked to change streams... Imagine how much harder that would be having multiple Parts, all but the drums with multiple chord choices.

Computer systems SEEM to have a much easier time of this, streaming multiple files simultaneously, but the thing is, they aren't REALLY realtime. The computer will pre buffer data (because it knows what is coming) to give the illusion of realtime performance. It only needs a few milliseconds to do it, but in a realtime environment, those few milliseconds are just enough to give you glitches and stinky timing.

Personally, as expensive and as unproven as this technology is, I think I am prepared to wait a few more years until the hardware catches up to needs, and the whole thing gets a bit more mature. It just seems a little kludgey right now.

I completely forgot about that, I stand corrected.

IF Frankieve will post some picture of the Audya mainboard where are located the SAM9708+SAM9707 then I can post some dream documentation.
Only in this way you there can full understand what this keyboard is able to make or not.

I have already design 6 different boards with the Dream DSP and I know really well the all possible features.
Let see if Frakieve will display some..
