11 – Synchronization–Tempo map98 TASCAM 788 Digital PortaStudio4 Cue the sequencer to the start of the song (it isnot possible to record from part of the waythrough).5 Press ENTER/YES on the 788. The sync track isnow “armed” and the display shows Waitfor Start.6 Start playing back the sequence. If the connec-tions have been made properly, the 788 displayshows Recording...To interrupt the recording of the sync trackbefore the end, press NO.7 At the end of the sequence, or if the sequence isstopped, the 788 display shows Complete.Press EXIT/NO to save the sync track. If youpress ENTER/YES at this point, you will re-armthe sync track and you will have to record itagain.NOTEThe 788 and the sequencer should be independently con-trolled here (that is, neither should be a control slave of theother). See “MMC and MIDI functions” on page 101.The start of the sync track is always the ABS 00:00:00:00point, that is, the first beat of the first bar falls at the zeropoint. It is not possible to offset the sync track.Using the sync trackTo use the recorded sync track to control the externalsequencer from the 788:1 Make sure that the synchronization source forthe 788 is set to INT (internal)—see “Syn-chronization master/slave setting on the 788”on page 96. The MIDI OUT of the 788 should beconnected to the MIDI IN of the sequencer.2 Set the SYNC GEN parameter on the 788’sSYNC screen to SycTRK (see “Selectingthe master synchronization type” on page 96).3 Set the sequencer to respond to an externalclock source and make it ready to accept anexternal MIDI Start command.4 Return to the home screen on the 788, andpress PLAY. The sequencer starts playing backat the time position corresponding to the ABStime on the 788.NOTEYou do not have to start playback at the beginning of thesong. If you locate to a time position on the 788, thesequencer will pick up the correct time from the MIDI SPPdata output by the 788.Although it is possible to change to the bars and beats dis-play on the 788, the values displayed when using the synctrack do not correspond to the bars and beats on thesequencer, unless a tempo map is entered on the 788where the signature changes correspond to those in thesequence (note that even if the bar/beat position matchesthe sequencer, the tempo probably will not). You shouldtherefore usually use the ABS time values when locating,as these are generally more meaningful location values.Tempo mapYou can enter the tempo map to allow the 788 to sendtempo (clock) and SPP information to a MIDIdevice, when it is not possible to record a sync track.Another advantage of using the tempo map is that itallows you to locate to bars and beat positions on the788, as described in “Direct location (ii)” on page 61(using the sync track does not automatically map thebars and beats), and this is therefore a more “musi-cal” way of controlling the synchronization of the788 with a sequencer.Entering and editing the tempo mapYou must enter the tempo map manually, using theprocedure described here:1 Make sure playback and recording arestopped, and press the MENU key.2 Use the dial to scroll down to SYNC/MIDI, and press ENTER.3 Use the dial to highlight TEMPO MAP, andpress ENTER.
