Functions of the “Snapshot” front panel switch
The front panel switch labelled “Snapshot” has various functions:
a) to send a Snapshot of all the panel control knob settings
b) for setting the master MIDI channel
c) to reset the pocketC after a MIDI overflow at the MIDI in
To Send a snapshot
The snapshot function is not achieved by just pressing the snapshot switch, as
this could be accidentally pressed too easily. So to activate the Snapshot function, first briefly
press the Snapshot switch once, this causes the LED to flash, the Snapshot switch needs to be
pressed again within at least one second (whilst the LED is still flashing). This then invokes the
snapshot function, and the data from all 16 control knobs is transmitted from the pocketC.
To Set the Master Channel
The Master channel is used to select which channel the pocketC will transmit on
when using relevant presets. Some presets (such as the MIDI volume - preset 0) has each knob
on a different channel, whilst other presets have all knobs on the same channel, it is on these
presets that the Master channel is used. The Master channel is also the channel which the pocketC
will receive program change data on.
To set the Master channel, hold the snapshot switch down for at least one second
and keep it held down, the LED then stays on to indicate Master channel setting mode (do not
let go of the button until the required value has been selected). In this mode the control knobs
become channel selectors, and do not transmit the normal control data. To select a channel,
simply move one of the control knobs that relates to the channel required (to set channel 5,
move control knob 5). If you accidentally move the wrong knob, just move the correct one, as it
is the last knob moved that determines the actual Master channel set.

The Sys-Ex data can be broken down into sections, the first part is the Sys-Ex format for the
pocketC Single Dump, which is (numbers in Hex):
F0 00 20 20 14 00 20 preset channel (16 bytes) data (32 bytes) F7
F0 Sys-Ex byte
00 European Sub ID
20 Doepfer Sub ID 1
20 Doepfer Sub ID 2
14 Device “pocketC”
00 reserved
20 Command Byte “Single Dump”
00 ~ 7F Preset Number
00 reserved
00 ~ 10 Parameter 1. There are 16 data bytes setting the MIDI channel of each
knob, a setting of 0 sets the knob to the Master Channel.
00 ~ 7F Parameter 2. There are 16 data bytes setting the event type for each knob,
a setting of 7F defines “No Event” to the knob.
00 ~ 7F Parameter 3. There are 16 data bytes setting the additioanl event data for
each knob. The definition of parameter 3 depends on what parameter 2 is
set to.
