Pocket Fader Sysex redux

I looked at the sysex data above and I found the command byte for
requesting a snapshot of the data of the faders

experimenting with the Peter Elsea’s [Lsx] external I sent a command
byte ’26′ to the Doepfer:
F0h 00h 20h 20h 14h 00h 26h 00h 00h F7h
^

command byte ’26′ is a ‘Single Dump Request’ which returns: channel
number (1-16), event type, 0 = controller , and midi controller
number (cc# 7= Volume)

as follows:
240 0 32 32 20 0 32 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 247

and since my Pocket Fader is set to preset ’1′ this looks correct
e.g. sending cc# 7 on ch’s 1 -16

-but- what I want to do is send a command byte to the Pocket Fader
that simulates hitting the ‘snapshot’ button on the PF panel

so that it dumps the values of all 16 faders – at once – to my Max
patch — giving me something like:
176 7 127 177 7 0 178 7 0 179 7 0 180 7 0 181 7 0 182 7 0 183 7 0 184
7 0 185 7 0 186 7 0 187 7 0 188 7 0 189 7 0 190 7 0 191 7 0
which is what I get from [midiin] after hitting the ‘snapshot’ button

I’m trying to initialize a patch automatically rather than hitting
the ‘snapshot’ button…

does anyone happen to know the secret Doepfer command byte for
getting this?

thanks in advance!

I just asked them directly, and they responded, that it had been
planned, but as its dicontinued it will never happen…
That command just doesn’t exist…

I might ask them if there is a way to hack it, but this might not be
worth it…
