For the proper synchronization, the "MIDI Clock" tempo must be between 30 and 300 BPM. For
lower or higher tempo, TR-808’s sequencer already can’t synchronize. Reaction of TR-808 to "Start",
"Stop" and "Continue" MIDI commands is shown on pic. 6.
4.3. SYSTEM EXCLUSIVE MESSAGES
The interface disposes with MIDI System Exclusive communication system for remote control and
programming. With help of System Exclusive messages, global parameters can be changed and
instrument and program maps can be defined. System Exclusive communication enables direct control
of the interface too.

calculation of hexadecimal numbers. Generator is based on Java scripts so it is possible to use it with
any PC operation system, but a web browser must be installed on the computer:
