MultiTrack (Advanced): Changing the 10mS time base
There is a second mechanism for changing the speed of the SuperTimers. This was introduced in dialect 20, August 2007. You can change the basic 10mS SuperTimer clock interval to some other value from 1 to 255mS. Set U0 to the required value in mS and then execute a
SPxCmd1 1,!CPU
This affects all timers that use the SuperTimer mechanism, which is any timer that can have a duration counter up to 16,777,215 (Pause, fSTTimeSince, WaitOnT, etc). If you set the interval to 1, the timing will run 10 times faster than normal. If you set it to 256, the timing will run 25.6 times slower than normal giving you a timing range of 49.7 days. Due to the resolution of the internal math, the re-scaling will produce an error of up to 0.2% at the slow end of the scale. The actual error will be the error produced by rounding 65,536/U0 to the nearest integer. If U0=0 it reverts to the default 10mS.
Note that it makes little sense to run the SuperTimers with a clock that is faster than the “loop time” of your program.
