aide demandée probleme midi avec la jomox mbase 11

Only actual chosen preset hex dumps are sent and received with Sys
Ex data because the sound control is normally done with midi cc
controllers.

The System Exclusive control command line looks as follows:

$F0(SysEx begin), $31(JoMoX- manufact. code), $7F(Command Sys
Ex dump), $57(Product code), $XX(Preset
No.),XX(Data0),XX(Data1),..., $F7(End of SysEx)

16 bytes (0..255) of data per preset are transmitted. They are split
into MSB (bit 7) in Data0 and LSB 0..127 in Data1. The MSB (Most
significant bit) is coded in Data0 = 1 or = 0, depending if bit 7 of the
actual byte was set or cleared.

The numbers and digits of Sys Ex sequences are shown, as always, in
hexadecimal signs
