Subject:Re:Mojo - Latency in general

As with many things related to human perception, sensitivity to latency can vary over a fairly broad range. While generally not a problem, it can become an issue when one keeps in mind the entire "latency chain". Latency creeps in through many channels:

1. The instrument itself - the delay between providing an input (pressing a key, for example) and creating an electronic output.
2. The signal chain - are there any digital devices in the chain after the instrument? Digital mixers are common these days - they add latency, as do outboard processing gear.
3. The monitor speaker/amplifier - many have DSP in them these days - that adds latency.
4. The location of your monitor speaker/amplifier - sound travels slowly, thereby creating a latency between the speaker creating the sound and you hearing it. In round number, if you move your amplifier/speaker further away from you by 1', you will add about 1ms of latency to the chain.

As you can see, the latencies can really start to stack up.

Generally speaking, about 5ms of latency is tolerable by almost everyone. As the latency increases beyond that, more people will notice it. 10 to 15 ms total latency is often OK, but that is moving towards the upper end of the spectrum. 15ms latency is analagous to playing an (analog) electric guitar with the amplifier about 15' away.
