Bc2000 (for the BCF2000 & BCR2000)

Hello everybody
I am a new BCR2000 user and I need some help.
I’ll try to explain :

I tweak my Waldorf Blofeld with BCR2000.
Blofeld is a particular hardware, because it uses a 2 families of MIDI messages to change his sound parameters – MIDI CC and MIDI SysEx.
I prepared my own presets for BCR2000 with BCManager of Mountain Utilities (very pleasant soft – thanx to its author). No problems, everything works but…
I would like to customize some SysEx messages, (but I don’t know how – I’m not really strong in SysEx programming, far from it) for example:
Blofeld proposes a choice of Modulation Sources like that:
0 off
1 LFO 1
2 LFO1*MW
3 LFO 2
4 LFO2*Aftertouch
5 LFO 3
and so on…

I captured Blofeld SysEx message that corresponds to this order with BCManager and it looks like that:

a b c d e f g h i j
F0 3E 13 00 20 00 00 0A 00 F7
F0 3E 13 00 20 00 00 0A 01 F7
F0 3E 13 00 20 00 00 0A 02 F7
F0 3E 13 00 20 00 00 0A 03 F7
F0 3E 13 00 20 00 00 0A 04 F7
F0 3E 13 00 20 00 00 0A 05 F7
and so on…
where (according to Blofeld manual):
a,b,c,d – a fix values of Blofeld ID
e – Sound Parameter change
f – Sound Mode Edit Buffer (another value gives a Multi Mode Instrument 1…16 Sound Edit Buffer
g – Parameter index high byte
h - Parameter index low byte
i – New Parameter value
j – End of Exclusive

I put this line to Custom Output page of BCManager :
$F0 $3E $13 $00 $20 $00 $00 $0A val $F7
I put the Min and Max values.
Everything works well – I turn the encoder: the LED lights on, BCR sends a message, Blofeld receives the message, but…
My master keyboard has no Aftertouch (and some others features) and I would like that BCR passes from LFO1*MW to LFO2 and then “jumps” from LFO2 to LFO3 directly without any access to LFO2*Aftertouch parameter.
Could I program that?
Thank you for your help
