H The gate signal applied to this socket is inter-
nally connected with the signal coming from the
button 4. If either of these is high, the module
gate is high.

$ Audio Out
Socket $ is the audio output of the A-112.
H The audio signal from the DAC passes a
simple low-pass filter to suppress the
sampling frequency. It is possible to bypass
this internal filter if a more sophisticated low-
pass filter (A-120, A-121, A-122) is used or if
the sampling frequency should not be sup-
pressed for special effects. For this the inter-
nal jumper J1 has to be removed.
% MIDI In
Socket % is the MIDI input used to receive sample
data (SysEx dump) via MIDI. For this the dump or
wave dump mode has to be selected (see above) and
the gate has to be low.
Moreover a sample dump request or a wave dump
request message can be received by the A-112 in this
mode.
The MIDI SysEx message for a sample dump re-
quest has the following structure:
F0
00 20 20
Doepfer SysEx-ID
7F
< bank>
bank number (00 : S1, 01 : S2)
F7
When receiving this message the A-112 transmits at
the MIDI output & a sample dump (LED is on). The
length of the dump is 74.909 bytes altogether. Additio-
nally the current sampling frequency is transmitted.
The SysEx message for a wave dump request has
the following structure:
