The Linear Time Base Method
To achieve the best possible Timing, the MIDEX-8 uses the Linear Time
Base method. This new approach to optimize time-critical MIDI data
transfer is the result of a close co-operation between Steinberg and
Access Music.
The Problem
The new multitasking operating systems are often not capable of really
accurately transferring MIDI data, even on very fast computers. The
problem is caused by the sequential method that these systems use to
share the system resources between all running applications. The in-
tention of the method is to allow for a virtually simultaneous process-
ing of different tasks. But when time-critical processes are involved, this
method often results in slight timing problems. This might not be of
great importance for many applications, but a timing difference of 5
milliseconds during a MIDI data transfer is clearly noticeable.
The Solution
The solution is called LTB – Linear Time Base. This method adds an ad-
ditional time information to each MIDI Event and sends the event to
the MIDEX-8 early.
• For this reason, the MIDEX-8 “knows” in advance which MIDI information/note
to transfer next.
• Monitoring the current time position, the MIDEX-8 assigns the individual MIDI
Events to the current position of your Song and sends the MIDI Event at the
musically correct time.
