Sysx Data
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 Pro Audio to stop receiving. The currently selected
bank now holds the received Sysx data.
You can also add a DRM for any unlisted instrument. For more
information on how to do this, read the section ÒMore about Dump
Request MacrosÓ 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 Pro Audio 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 Pro Audio
transmit Sysx data more slowly, as described on the previous page.
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.
My Equipment Is Not receiving Sysx from Pro Audio
Make sure the instrument is set up to receive System Exclusive
messages. In the Sysx View, make sure the right destination port is
selected. Verify that the Sysx message originally transmitted from the
same kind of instrument. An instrument will not recognize Sysx
messages from a different make or model of instrument.
Finally, try adjusting the parameters in the
ttsseq.ini
Þle, as described
earlier in this chapter.
Timing Requirements When Receiving Sysx
Some MIDI devices have special timing requirements when receiving
System Exclusive transmissions. If your equipment has problems
receiving System Exclusive data from Pro Audio, you might need to
introduce some small delays to allow the equipment to digest the
information it is receiving.
The
ttsseq.ini
settings SysxDelayAfterF7=
n
and
SysxSendDelayMsecs=
n
let you control the timing of System Exclusive
transmissions.
Some devices have problems receiving System Exclusive data sent from
Pro Audio until you add this single line:
SysxDelayAfterF7=1
