TRANSFERRING DATA BETWEEN THE PSR-E303/YPT-300 and a COMPUTER

The PSR-E303/YPT-300 includes 102 preset Songs, but you can load other Songs from your computer and use them in thesame way as the preset Songs as long as the loaded Song is SMF format 0*.Loaded Song data will be stored in Song numbers beginning with 108.In order to perform the operations described in this section you will need to use a computer connected to the Internet todownload the free Musicsoft Downloader application from the URL listed below.

* The SMF (Standard MIDI File) format is one of the most common and widely compatible sequence formats used for storingsequence data. Most commercially available MIDI sequence data is provided in SMF Format 0.

You can download the Musicsoft Downloader application from the following website. Make sure that your computer has anInternet connection.

The minimum computer requirements for Musicsoft Downloader operation are as follows:

Installing Musicsoft Downloader

You can transmit Song files from your computer to your PSR-E303/YPT-300s Flash Memory.For details about how to transmit Song data using the Musicsoft Downloader application, refer to the Online help topicTransferring Data Between the Computer and Instrument (for unprotected data) of the Musicsoft Downloader.

Data that can be loaded to the PSR-E303/YPT-300 from a computer Songs : 99 Songs max (Song numbers 108-) Data : 373 kilobytes Data Format : SMF Format 0 File : 05PK.USR (user file)

***.MID (MIDI Song)

Use the power adaptor when transferring data. The data can be corrupted if the batteries fail during the transfer. Never turn the power off and never plug/unplug the AC power adaptor during data transmission. Not only will the

data fail to be transferred and saved, but operation of the flash memory may become unstable and its contentsmay disappear completely when the power is turned on or off.

NOTE: The Musicsoft Downloader application may not be able to access the instrument in the following cases: During Style playback During Song playback

NOTE: Close the window to exit from the Musicsoft Downloader and re-enable control of the instrument.

You can transfer backup data, including the five User Songs stored to the instrument, to a computer as a user file byusing Musicsoft Downloader. For details about how to transmit Song data using the Musicsoft Downloader application,refer to the Online help topic Transferring Data Between the Computer and Instrument (for unprotected data) in theapplication.

Data that can be transferred to a computer from the PSR-E303/YPT-300 User file (05PK.USR: backup data containing five User Songs) Songs transferred from a computer

The backup data, including the five User Songs is transmitted/received as a single file. As a result, all backupdata (including the five Songs) will be overwritten every time you transmit or receive. Keep this in mind whentransferring data.

NOTE: Preset Song data cannot be transmitted from the PSR-E303/YPT-300. Do not rename the user file on the computer. If you do so, it will not be recognized when transferred to the instrument.

By default (factory settings) the instrument ordinarily functions as a 16-channel multi-timbral tone generator, and incoming data does not affect the panel voices or panel settings. However, the MIDI messages listed below do affect the panel voices, auto accompaniment, and songs.

When the accompaniment is started, an FAH message is transmitted. When accompaniment is stopped, an FCH message is transmitted.When the clock is set to External, both FAH (accompaniment start) and FCH (accompaniment stop) are recognized.

Messages for these control change numbers cannot be transmitted from the instrument itself. However, they may be transmitted when playing the accompaniment, song or using the Harmony effect.

Effect map * When a Type LSB value is received that corresponds to no effect type, a value correspond-

ing to the effect type (coming the closest to the specified value) is automatically set.* The numbers in parentheses in front of the Effect Type names correspond to the number
