SYSTEM EXCLUSIVE (Generalmusic system exclusive)

Via MIDI, WK2 is able to recognise several different System Exclusive messages that con-

trol various parameters of the instrument: effects, master tune, master transpose.

The relative SysEx strings for the parameters in question are as follows:

REVERB CHANGE F0,2F,30,01,00,00,00,13,00,vv,F7

(vv= from 00h to 15h)

REVERB LEVEL F0,2F,30,01,00,00,00,13,01,vv,F7

(vv= from 00h to 7Fh)

Note: The reverb volume selected from the instrument panel must be set to its maxi-

mum setting (127)

REVERB TIME F0,2F,30,01,00,00,00,13,02,vv,F7

(vv= from 00h to 7Fh)

CHORUS CHANGE F0,2F,30,01,00,00,00,13,05,vv,F7

(vv= from 00h to 15h)

CHORUS LEVEL F0,2F,30,01,00,00,00,13,06,vv,F7

(vv= from 00h to 7Fh)

CHORUS RATE F0,2F,30,01,00,00,00,13,07,vv,F7

(vv= from 00h to 7Fh)

CHORUS DEPTH F0,2F,30,01,00,00,00,13,08,vv,F7

(vv= from 00h to 7Fh)

MASTER TUNE F0,2F,30,01,00,00,00,07,00,vv,F7

(vv= standard value 40h + / - 40h )

MASTER TRANSPOSE F0,2F,30,01,00,00,00,09,02,vv,F7

(vv= standard value 18h + / - 18 h semitones)

IMPORTANT: All the numbers within the SysEx string must be expressed as “HEXA-

DECIMAL” codes. Specific midi channels are not required for system exclusive mes-

sages.
