9.6 Latency
Latency is a side effect which occurs when connecting devices together
whether by analog means, MIDI or Link. Clock signals or triggers are sent
at one point in time and received by the other device at another point in
time. This may be extremely short and In most cases there is little or no
noticeable effect. However, some errors, even at a milli second level, may
be an issue. Most devices therefore have a latency compensation model
where parameters can be adjusted to offset the clock to help deal with this.

NOTES
9.7 Analog Application Example - T-1 Primary Clock
T-1 can operate as the primary clock device in a setup where other devices will follow. This is a
common conguration. Matching up the clock pulses and run signals is important to ensure the right
tempo synchronisation. Analog synchronisation options can be edited in the T-1 Cong tool.

Pam’s New Workout default key settings:
• PPQN = 24 - Matches T-1
• Run? = Set to Y, i.e. Yes. To allow a run input rather
than automatic start on sensing a clock signal. This is
a more accurate conguration. T-1 Run set to give a
gate high for play and low for stop.
T-1 Environment
Latency is usually managed on a trial and error basis as there is no absolutely
accurate process or formula. It can be very difcult to ascertain the ms error with
connecting gear. If there are noticeable errors then the clock latency can be adjusted
incrementally. The available range is -200ms to 200ms but it is advised to always
start with the default of 0.0ms.
