Operation Modes
After power on all LEDs turn on and go out from left to right. Then all LEDs light up for a
short time and go out. After that the current software version is indicated for a short time by
using the Bank and Number LEDs. The Bank LED shows the main software version, the
Number LED the sub-version (e.g. Bank LED #1 only indicates software V1.0, Bank LED #2
and Number LED #4 on indicate V2.4).
Then the normal operation mode is called up. As long as no preset has been defined (either
by pressing the Bank/Number buttons or by receiving a Midi program change message via
Midi) the LEDs of Bank #1 and Number #1 are flashing. This in the signal that so far no
preset has been selected and consequently the states of all parameters are still undefined.
B4 Mode
This mode is intended for the combination of d3c with the organ emulation B4 of Native
Instruments and is up to now the only available mode. Because of the more versatile
functions – compared to the EVB3 and Remote mode – the B4 mode can be used for other
applications too, e.g. to control any Midi sound module via the note and progam change
messages that are available in B4 mode.
Pay attention that most manufacturers count the Midi program change numbers from
0....127 others from 1...128. In this manual we use the range 0...127 as this is more
common. If the device connected to the Midi output of d3m does not respond as
expected the different counting ranges may be the reason. In this case you simply
have to add "1" to the program change number stated in this manual. Same applies
for Midi channels too (i.e. counting from 0 to 15 resp. 1 to 16).
In the B4 mode the 22 buttons are used to transmit Midi Program Change Messages. The
number buttons generate the program numbers 0...11 (resp. 1...12 in the 1...128 counting
system). The bank buttons are used to add a fixed value ("offset") to the program number
generated by the number buttons. The offset value generated by the bank buttons is a
multiple of 12. The offset is 0 for bank #1, 12 for bank #2, 24 for bank #3 and so on. The
table below shows an overview of the available program change numbers for each bank:
Program number range for counting system Bank
0 – 127 1 – 128
1 0 – 11 1 – 12
2 12 – 23 13 – 24
3 24 – 35 25 – 36
4 36 – 47 37 – 48
5 48 – 59 49 – 60
6 60 – 71 61 – 72
7 72 – 83 73 – 84
8 84 – 95 85 – 96
9 96 – 107 97 – 108
10 108 – 119 109 – 120
The corresponding formula for the resulting program change number generated by the
number and bank buttons is this:
Number – 1 + 12 x (Bank – 1)
Example: Number = 5, Bank = 3
The resulting programm number is 5 – 1 + 12 x (3 –1) = 4 + 24 = 28.
