The PDP-400 features a built-in “sequencer” which can be used to independently record up to ten separate
parts of a single musical composition, plus a rhythm track. Each part is recorded on one of the Performance
Memory “tracks” accessed via the [RIGHT/1TR], [LEFT/2TR], [ORCH/3-10TR], and [RHYTHM] buttons. The
music data that you record is stored on a 3.5" floppy disk loaded into the PDP-400’s disk drive unit. Up to ap-
proximately 60 songs can be recorded on a single disk, depending on the amount of data contained in each
song. Before you can record, however, you must “format” a new disk, as described on page 38.
ZInsert a Formatted Disk..........................................................................................................................
If you haven’t already done so, make sure that a properly formatted disk is loaded
into the PDP-400 disk drive (see page 38), and that the disk’s write protect tab is set to
the “write” position (tab closed).
NOTES•If you insert an unformatted disk, “For” will appear on the SONG NUMBER display.Please format the disk before proceeding.•If a disk is already loaded and the [SONG SELECT] indicator is out, press the [SONGSELECT] button so that the indicator lights before proceeding.

Easy One-pass Recording & Playback

Select a SONG NUMBER between 1 and 60 for the piece you are about to record
(up to 60 different songs, each with a different song number, can be recorded on a
single disk). Make sure the song number you select has not already been used for a
song previously recorded on the disk you are using.
NOTES•If the [RIGHT/1TR], [LEFT/2TR], [ORCH/3-10TR], or [RHYTHM] button indicatorglows green when a song number is selected, the corresponding track of the selectedsong already contains recorded data. Before recording over a song that containsprevious data, we recommend that you delete the entire song as described in “Delet-ing a Song” on page 40.

CSelect a Voice .........................................................................................................................................
Use the VOICE selectors to select the voice you want to record with. You can try
out the selected voice on the keyboard before proceeding.
VEngage the Record Ready Mode...........................................................................................................
Press the [REC] button so that its indicator lights. The [RIGHT/1TR] indicator
should also glow red at this point, indicating that you are ready to record on track 1.
●Remaining Disk Space Display
When you release the [REC] button the amount of disk space available for record-
ing will appear on the SONG NUMBER display (in approximate kilobytes). With
an empty disk you should have about 700 kilobytes of space for recording (room
enough for about 50,000 notes if no other PDP-400 functions are used). If no space
is available for recording, “FUL” will appear on the display.
