How to Upgrade VoicePrism Software 

1.  Make note of the current version number (press the 

Utility

 button and tab to the 

Version

 

page). 

2.  Chain several units together by connecting the 

MIDI Thru

 port to the 

MIDI In

 port of the 

next unit.  Connect the MIDI output from your computer to the 

MIDI In

 port of the first unit. 

3.  Using a MIDI tool such as MIDI-OX load the “Upload.syx” file. 
4.  Transmit the file.  All units should display a message saying “YOU MAY START 

UPLOAD…” (see 

Figure 2

)   Note, the “Upload.syx” file is only for internal use and should 

never be made available to the customer because it bypasses the download password 
mechanism. 

5.  Load and transmit the “ClearFlash.syx” file.  This will erase the VoicePrism software flash 

chip.  Note, erasing the flash will not only remove the software but also clear all user 
presets and preference settings. 

6.  Wait for at least 10 seconds after sending the “ClearFlash.syx” file. It takes a few seconds 

to erase the flash. 

7.  Load “VP

xxx

.syx” where 

xxx

 represents the current version number.  If you are using MIDI-

OX make sure that there is a 60 ms delay after each F7 (one of the options in the Sysex, 
Configure dialog box in MIDI-OX, see 

Figure 1

 for an example).  This might not be absolutely 

necessary, depending on the type of MIDI device you are using. 

8.  Transmit the file. 
9.  When the file has been sent, all units should reset automatically. 
10.  Confirm that the new software has been loaded by checking the version number again. 
11.  Perform the BIST procedure (see below).
