Wireless gaming mice that use a USB receiver have become more popular, and technology has evolved to greatly reduce the latency, to the point where some wireless options are as good as wired ones.įor this reason, we place our connector on the left-click button instead of opening the mouse and connecting it directly to the microswitch itself.
USB 2 VS USB 3 LATENCY BLUETOOTH
A Bluetooth connection isn't recommended for gaming, but it's still good for office use, and most people won't notice any delay unless the latency is extremely high. Generally, wired mice have the lowest latency, and Bluetooth mice have the highest latency. The mouse's connection type affects the click latency. Especially in online, competitive games, having a low latency mouse can give you an advantage over your opponents if they have mice with high latency.
Of course, you also need a computer and a monitor with low input lag, but having a responsive gaming mouse can make the difference between winning and losing. Although most people can't visually or audibly tell the delay between when the mouse is clicked and when the action appears on the screen, a mouse with high latency can make subtle differences in games. So yes, FireWire might be better (off the top of my head: it has something called ‘Constant bit-flow’ or something, allowing the steam to go through without those pesky ‘windows’ that the USB controllers introduce.Having a mouse with low click latency is extremely important for gaming. Which are only “playing”/triggering notes on a certain synth (which is clocked from a real hardware source) I personally do not use USB MIDI other than notes that do not have to be perfectly in time, USB + MIDI is ok if you sequence and send out all MIDI information from that computer/DAW into hardware with absolutely no external sequencing.Īnyways, IMO it’s not worth even trying to use it seriously, That’s quite a lot of cyclic error on your tempo signal.” The period between each tick is usually 21ms, with a 20ms tick every so often to average out at 20.833. The ideal timing of the clock ticks should be:ĭelayed until the next USB frame, the best case timing will be:
USB 2 VS USB 3 LATENCY SERIAL
If the line is clear, the start bit of a serial MIDI message can happen on the next transition of the serial interface’s baud rate generating clock, which has a period of 32 microseconds for plain old MIDI.Ī quick example to show you what this means in practice…Ī tempo of 120 bpm at 24 ppqn means a clock tick period of 20.833ms (rounded to 3 decimal places) You can send multiple MIDI events in a single frame, which gives a big advantage over serial MIDI as polyphony increases, but for getting a single byte of MIDI clock pulse out of a CPU, USB just can’t match serial MIDI. one frame every millisecond.Ī MIDI event being transmitted over USB must wait between zero and one milliseconds before it is actually sent, depending on when the event was generated by the processor relative to the regular frame period of the USB host. “USB MIDI has a bit of a problem with timing.įull speed USB runs at 12 mbps, a data rate over 300 times faster than serial MIDI.īut USB is frame based, with a frame rate of 1kHz, i.e. (copied from a well known source, a master of MIDI -perfectly sums up the “problems” with USB based MIDI) Hey there, I’m just copy pasting this information from the maker of Sequentix, haven’t found a better explanation gives you a good idea of “why” USB is not ideal for TIMING (it’s ok IMO for note on/off messages)
