Local Control; Using Initial Setup Send With A Sequencer; External Clock - Yamaha PortaTone PSR-275 Owner's Manual

Local Control

This function lets you enable or disable keyboard control over the PSR-275/273's
voices in the Function mode (page 60). This would come in handy, for example,
when recording notes to MIDI sequencer. If you are using the sequencer to play
back the voices of the PSR-275/273, you would want to set this to "off" — in
order to avoid getting "double" notes, both from the keyboard and from the
sequencer. Normally, when playing the PSR-275/273 by itself, this should be set
to "on."

Using Initial Setup Send with a Sequencer

The most common use for the Initial Setup Send function is in recording a song
on a sequencer that is intended for playback with the PSR-275/273. Essentially,
this takes a "snapshot" of the PSR-275/273 settings and sends that data to the
sequencer. By recording this "snapshot" at the start of the song (before any actual
performance data), you can instantly restore the necessary settings on the PSR-
275/273 in the Function mode (page 60). Provided there is a pause in the song,
you could also do this in the middle of a song — for example, completely chang-
ing the PSR-275/273 settings for the next section of the song.

External Clock

This determines whether the style and song playback functions are controlled by
the PortaTone's internal clock (off) or by MIDI clock data from an external
sequencer or computer (on).
This should be set to on when you want to have style or song playback follow the
external device (such as a rhythm machine or a sequencer). The default setting is
off.
These settings can be made in the Function mode (page 60).
MIDI LSB Receive Cancel
Determines whether the LSB data of Bank Select is received or
not. Press and hold the lowest key and turn on the power to change
the setting (LSB is ignored).
To restore MIDI LSB Receive Cancel to normal (LSB is recog-
nized), turn on the power again normally.
