I am thinking of writing a program to convert/exchange 
Octamed MIDI messages to SYSEX format that can be loaded into a standard 
sequencer....I don't know how other sequencers load SYSEX messages, so could 
anyone please tell me what sequencer they use and how messages are loaded.

I have CUBASE (Atari) and OCTAMED (Amiga)


presumably you have for example:

CUBASE PART file:		OCTAMED MIDI MESSAGE file:

/-----------\                   /-----------\
|  HEADER   |			|  HEADER   |
| 100010010 | 			| 010010010 |
\===========/		        \===========/
/   DATA    \			/   DATA    \
| 010010011 |			| 010010011 |
| 101001001 |			| 101001001 |
| 010010101 |			| 010010101 |
\===========/  			\===========/

So if I strip the header I can interchange the remaining data by adding a new
header.

Any help would be greatly appreciated on information for any sequencer.

Thanks
JOE

I use Bars & Pipes Pro 2.5 (which is free on Compuserve)

B&Pipes loads sysex through an accesory called BigSys, it will load raw SysEx
files so to convert a message do the following

All Midi SysEx dump packets begin with 'f0' and end with 'F7'

Load up a hex editor (File X is a good one)

Remove the Octamed header. ie. any bytes before the first F0

save file and import into B&Pipes.


B&Pipes also will store SYSEX messages in a track as other sequencers will so
the best way to exchange SYSEX between various sequencers is to store the
SYSEX in a track as save as a midi file.

It may not be possible to add your own header to a raw sysex message as some
headers also store the length of the message in hex.
