SYSTEM SETUP
TEMPO MAPS
The Akai DD/DR system allows you to create tempo maps for use when synchronising to MIDI
sequencers. On the RE32, this function is accessed by pressing TEMPO (F5) on the main MULTI
SETUP page. You will see this screen display:
Any machine in the system can act as a master to a sequencer synced to the machine using MIDI
Time Code (MTC) or MIDI clock with Song Position Pointer (SPP). Of these two options, MTC is
recommended for more accurate synchronisation as this is timecode via MIDI although if your
sequencer does not have MTC, MIDI clock with SPP is a perfectly good way to synchronise your
sequencer to the system.
The principle behind a TEMPO MAP on the Akai DD/DR system is that a machine can issue tempo
changes and changes in time signature to the sequencer as part of a project. Without this, any
variation of tempo in the recorded material on disk would not be passed to the sequencer and the
two machines would very quickly drift out of sync. By placing tempo changes and time signature
changes at the appropriate point, the sequencer can follow the system exactly. To achieve this, of
course, your sequencer must be set to external sync so that the Akai DD/DR is in control of its
tempo and time signature. ADDITIONALLY, THE SELECTED MACHINE MUST BE SET TO
GENERATE MIDI SPP. This is done in the SINGLE MACHINE SETUP / SYNC page described
later.
When working with MIDI sync in this way, it is recommended you use the MIDI BBC (bars/beats/
clocks) time display style set in the SETUP / DISPLAY page.
NOTE: When MIDI B/B/C is selected as the TIME DISPLAY style, this will have implications on
functions elsewhere on the RE32.
For example, if you use NUDGE, the DATA ENTRY +/- keys will nudge in beats and SHIFT +
+/- keys will nudge in clocks (if you need more accurate nudge amounts, select an H/M/S time
display). The number of beats/bars you nudge by can be set in the NUDGE SET page.
LOCATE functions also change slightly when MIDI B/B/C is selected in that you may go to a
specific bar/beat as well as to time and/or a locate memory.
You will also note that the PLAY TO and FROM work in bars and beats (the exact amount may
be set by pressing SHIFT+PREROLL)
PRE-ROLL and CYCLE PRE-ROLL are also expressed in bars when MIDI B/B/C is selected
as the time display.
The system can store up to 10 tempo maps in memory. These are associated with any given
project and are saved to disk with the project (typically, you will probably only ever make use of
SONG 01 as the tempo map for your project). A tempo map can have up to 200 tempo changes
and up to 20 time signature changes.
Tempo maps may be named (up to 6 characters
3
) in the usual way.

This is to maintain compatibility with the Akai DR8 which can only use a 6 character name.
