5 – Recorder operations–Setting the playback position50 TASCAM 788 Digital PortaStudioSetting the playback positionThe 788 provides you with a number of ways to setthe position from which playback starts when youpress the PLAY key. Some of these are described inthe section (“Location operations” on page 60).The ways of setting the playback point which involvethe transport keys are described here.Return to zero (RTZ)This allows you to return instantly to the “zeropoint”, (expressed as the absolute time).To return to zero (from stop, play or record):1 Press and hold down STOP.2 Press REW. Playback/recording stops and theplayback position returns to the zero point.Last Recording Position (LRP)This is an extremely useful feature that allows you toreturn instantly to the point where recording laststarted. You can use this in any of the following situ-ations (these are examples, you may think of othersfor yourself):• after you interrupt a bad take halfway through therecording and want to return instantly to the sameposition to retake• after a successful take, and you want to return tothe point where recording started to check the take• when you are recording a number of differenttracks in turn, all to start from the same point• after a take, you may want to set the point wherethe take started as a reference location markTo return to the position where recording last started(from stop, play or record):1 Press and hold down the STOP key2 Press F FWD. Playback/recording stops, andthe playback position returns to the pointwhere recording last started.Jog positioningTo position the playback point precisely, you can“jog” the playback position, using the dial. As youmove backwards and forwards through the recording,you can hear the recorded sound at slow speed, eitherbackward or forward, depending on the direction youare turning the dial.1 Position the playback point to the rough posi-tion where you want the final point to be.2 Press and hold the STOP key and press thePLAY key. The display shows a view of thewaveform of the currently selected track at thecurrent playback position.3 Press the SELECT key of the track that youwant to view (pressing the 7/8 key changesbetween viewing track 7 and track 8). The dis-play changes to the waveform of that track.4 Use the Ó and Á keys to zoom out and inrespectively horizontally. This is, pressing theÁ key will increase the amount of space on thescreen taken by a certain amount of time, andpressing the Ó key will make the same amountof time take less space on the screen. The threezoom levels available are: x 1, x 2 (allow-ing approximately single-frame accuracy inadjustment), and x 32 (allowing approxi-mately an accuracy of about 10 sub-frames).The resolution is shown below the time display.5 Use the § and ¶ keys to adjust the verticalscale (the way that the volume of the sound isshown). The zoom levels here are x 1, x 2,x 4, x 8, x 16 and x 32. Pressing the§ key increases the vertical scaling of the dis-play, and pressing the ¶ key decreases thescale.TIPIf you can’t see any waveforms when you first enter thisdisplay, press the § key to zoom the volume so that youcan see the quiet passages.
