Re: Speed of sysex transfer

2013-08-23 by steve_the_composer

As people have pointed out, this group has been extremely active over the last day or two.  I did not see any replies about your "integer divisor" statement; so if someone replied already, please accept my apology (but only if I am repeating what someone else has said).

In the thread so far people have talked about primarily two types of timing--(1) rate of serial port data transfer and (2) tempo.

Sort of related to tempo, there's something I call resolution. Sequencers (and the midi files they create) sometimes refer to ppq--pulses per quarter (http://en.wikipedia.org/wiki/Pulses_Per_Quarter). 

I suspect that the precision with which someone lays down a track so it is 100% on the beat (or any other precise place) is more a matter of the resolution of the sequencer than the divisibility of the tempo into the rate of serial data transmission.

I could be wrong (and if so, my guess is that someone will let me know).
