I have one those Evolution 249C, and I don’t think that there is a delay of 60ms, when I play, there is so litle data that has to be sent and I think that the usb is fast enough to send that data.
In sweden there is a law that you have one week to return something if you don’t like it. Ask your dealer if you can have the same kind of deal, it could be harder if you buy it over the internet though…
My recommendations would be that you might get an edirol though, because I have heard that they have a higher resolution on the knobs…
The Evolution is supposed to have 128 steps while the edirol should have 256 or something…
I just made a search on usb speed and here is some text from an article
Then there’s speed. ADB was 10 kbps. Apple’s serial ports supported 230.4 kbps for LocalTalk. But USB has a 12,000 kbps (12 Mbps) bandwidth.
That compares favorably with almost all serial protocols, including 10 Mbps ethernet.
The Real World
The promise is 12 Mbps throughput, but does anything actually deliver it?
Thus far, the answer appears to be no.
In an article about Macworld Expo last year, Henry Norr wrote, “…the sustained transfer rate for the Mac (USB) version [of the SparQ drive] will be 0.7 MB/sec. That’s even slower than the parallel port version, which has a sustained rate of 0.9 MB/sec and a burst rate of 2 MB/sec.”
Converted to megabits per second, that put the USB SparQ drive at 5.6 Mbps – about half the rated bandwidth of USB. But then again, that’s the manufacturer’s specification, not a benchmark result.
Things have scarcely improved since then.
