Surge:
Poll rate and latency have nothing to do with it. I'm not talking about the amount of time between when you scratch the turntable and when it registers.
I'm talking about hitting the turntable, and instead of the input being 2-3 ms long like it is on the arcade and CS games, the turntable input is more like 40 ms long. This causes a ton of excess poors when you scratch, and makes the turntable lane bright with redness, making it harder to see fast scratches in songs like Checking You Out, Watch Out!!, etc.
The actual circuitry of a Beatmania IIDX controller does indeed send this signal for a very long time, and the only way to cancel it out is by programming whatever software you have, i.e. the arcade games or PS2 games, to ignore the signal after it has been recognized for 2 or 3 seconds.
When you increase the poll rate of your USB, you are increasing the number of times your USB is checked for a signal in a given amount of time, essentially reducing the amount of time it takes for your PC to receive this signal. This will in no way reduce the excessively long turntable signal that a IIDX controller sends naturally. You absolutely NEED to program that feature in the software to get the turntable to act the way it does on official Beatmania software.
As for the Radioshack adapters, well, they're all good. I have three different models, including the one you made a video on, and they're all great for reducing the amount of latency. It is physically impossible for it to be as fast of a response as it is for a PSX to parallel/LPT adapter, but for USB adapters, yes, they're the best I've found. However, a quicker response time does not solve the problem with the turntable completely. |
