System exclusive data
Troubleshooting
SysxSendPacketSize=n
System Exclusive bytes are transmitted in packets, with a 1/18-second default delay between each
packet. Setting this value to a smaller number will help slower synthesizers avoid overflowing their
internal buffers. This line sets the number of bytes between each Sysx transmit delay.
n = 1024 Default value (in bytes)

Troubleshooting
SONAR is not receiving Sysx messages
• Make sure all your devices are connected correctly.
• Make sure you have the right MIDI Input selected in Edit > Preferences > MIDI - Devices.
• Make sure that your instrument is set up to transmit System Exclusive data.
Sysx bank names don't show when I open a file
Sysx bank names are only saved in .cwp and .cwb files (not in .mid files).
SONAR doesn't include a DRM for my instrument
If there is no Dump Request Macro (DRM) for your instrument, you should select You start dump on
instrument, then initiate the Sysx dump from the instrument. Once the bytes received count stops
increasing, click Done to tell SONAR to stop receiving. The currently selected bank now holds the
received Sysx data. You can rename the bank if you want by selecting the bank and clicking Edit >
Name.
You can also add a DRM for any unlisted instrument. For more information about how to do this,
read the section “More about Dump Request Macros” on page 1071 earlier in this chapter.
Synthesizers reporting MIDI data errors
Some synthesizers will report data errors when you try to send Sysx information to them. This
usually happens when SONAR sends data at a rate too fast for the synthesizer to keep up. You can
use the SysxSendPacketSize=number setting in TTSseq.ini to make SONAR transmit Sysx
data more slowly, as described in “Sysx .ini file settings” on page 1075.
Try setting the number to 64. If that does not solve the problem, try successively smaller values. If
64 works, you may try larger values until it stops working; go back to the largest value that worked
and you will have the fastest transmission rate that the problematic synthesizer can keep up with.
