●When song data plays back with the wrong sounds

When song data created using the SC-55 or the SC-155 is played back by this unit, the sounds that were intended may not be selected. This can occur for one of the following two reasons.

❍Frame Draw function (p.110)

The SC-88/Pro has a Frame Draw function. This function allows you to create display data for each page using the front panel buttons, and to transmit the data you create as an exclusive message. By using this to create data in the appropriate sequence and timing, you can create display data with move- ment.

1. The wrong Variation number was selected

When a Variation number for which sounds do not exist is selected on this unit, the display will show a message of No INSTRUMENT (or for the Drum Part, No DRUM SET). Even if the relevant Part is not displayed, this message will be displayed briefly when any Part receives such data.

The data which specifies sounds is usually placed in the beginning of the song data, so check whether this message appears when the song data starts. If this message appears, it is possible that a control change Bank Select message (or for the Drum Part, a program change) within the song is incorrect. (p.126) Refer to the instrument list (p.154), and modify the data value so that an existing sound is selected.

2. The wrong sound map was selected

On this unit, the lower byte (LSB) of a control change Bank Select message (control change 32) can be used to switch sound maps (p.126).

Control Change 32 values

00:The map selected by the panel buttons will be used.

01:The SC-55 map will be selected.

02:The SC-88 map will be selected.

03:The Native map will be selected.

If values other than these are transmitted to this unit, a map for which this unit has no sounds will be selected, so a message of No INSTRUMENT will appear. In the case of the SC- 55/155/55mkII, the LSB of this Bank Select message is ignored, so sound selection will not be affected regardless of the value that is transmitted. However since Bank Select messages are used as a pair of upper and lower values (MSB and LSB), it is best to input 00 as the lower value (LSB) in your song data.

●Using screen display data for the SC-55 series

❍About screen display data

The level indicator area in the center of the SC-55/55mkII/SC- 88/VL/Pro display (bar display) is able to display 16 x 16 dot graphics that are transmitted to it as exclusive messages. By transmitting this data together with the song data, you can make the display change as the song progresses.

The SC-88/VL/Pro can hold 10 pages of display data. Exclusive messages can be used to display a specific page, and to adjust the duration for which each page will be displayed (p.193).

Also, text can be displayed in the INSTRUMENT display area, allowing song titles or lyrics to be displayed.

Even display data for the SC-55/55mkII can be used without change to produce the same display. In this case, the data will be displayed as the first page of the 10 pages.

●How to use a Part other than Part 10 as a Drum Part, so that two Drum Sets can be used simultaneously

❍About the Part mode

Each Part 1--16 can be used either for normal sounds (Normal Part) or for a drum set (Drum Part). This selection is made by the Part Mode setting. (p.27)

The mode of a Drum Part can be either Drum1 or Drum2. Since the same Drum Set will automatically be selected for Parts that have the same Part Mode, this means that up to 2 types of drum set can be used simultaneously.

For example if you set the Part Mode of Part 10 and Part 11 respectively to Drum1 and Drum2, you could select STAN- DARD1 Set for Part 10 and JAZZ Set for Part 11. If the Part Mode of both Parts 10 and 11 were set to Drum1, selecting STANDARD1 Set for Part 10 would automatically select STANDARD1 Set for Part 11 as well.

❍Settings via MIDI

To set the Part Mode using MIDI messages, you need to use system exclusive messages.

For example if you wish to set the Part Mode of Part 11 to Drum2, transmit the following message. (p.197)

F0 41 10 42 12 40 1A 15 02 0F F7

10 : Device ID (17)

40 1A 15 : Address (USE FOR RHYTHM PART of Part 11)

02 : Data (Part Mode Drum2)

To select a Drum Set after setting the Part Mode, transmit a program change to Part 11.

●Using Aftertouch

First connect a device that is able to transmit aftertouch messages to this unit. Be aware that some MIDI keyboards are not able to transmit aftertouch messages.

When this unit receives aftertouch messages, the way in which it responds will depend on its settings. With the factory settings or immediately after this unit has been initialized by a GS Reset etc., aftertouch messages will have no effect, so you will need to change the settings if you want aftertouch to do some- thing.

Aftertouch parameters are divided into the following two groups.

• Channel aftertouch (CAf):

These messages apply an effect to the entire Part of a given channel. For example if you hold down a "C-E- G" chord and then press strongly on just the "C" note, the effect will apply to all notes "C-E-G."

• Polyphonic aftertouch (PAf):

These messages apply an effect independently for each note number. For example if you hold down a "C- E-G" chord and then press strongly on just the "C" note, the effect will apply only to the "C" note.

Of the Channel Aftertouch parameters, the following seven can be set from the panel (p.30).
