(1) Delay + MIDI message length
Byte Description
2 MSBs
(Delay configuration)
00 : no delay.
01 : delay = 30ms
10 : delay = 60ms
11 : delay = 90ms
5 LSBs
(MIDI string length)
01 - 24 decimal
01h - 18h hexa
(2) Example of grouped controls
The control to chain can range from 0 to 39 (32 knobs + 8 sliders), 0 means that no control has to be
grouped.
In the case of there is a control to group, the chained control number (1-40, 6 bits wide) is divided into
3 times 2 bits, respectively sent with MIDI channel position (bits 5-4 of the control to chain),control
value position (bits 3-2 of control to chain), and checksum position (bits 1-0 of the control to chain)
Since 0 means no control to group, the number of the control to chain is increased by 1, for example,
chaining control 0 means that the grouped control number is 1.

(3) Bitstream Pro Mode & Autosend
Mode
Potentiometer
Slider
Switch Note
0 Jump Push -
1 Hook Toggle From ROM V2.0
Mode (potentiometer configuration): Hook/Jump : This allows to set the selected potentiometer
behaviour as Hook or jump mode, hook is used to avoid jumps when switching from one group to
another. The MIDI events are not sent until the potentiometer physical value is equal to the current
group value. Jump is the common behaviour, the Bitstream don't care about physical and group
mismatches, and send MIDI once the potentiometer tweaked.
Mode (Switch configuration): Toggle/Push : This allows to set the selected programmable switch
behaviour as toggle or push mode. When a switch is configured as toggle, a single push/release
toggle the actual switch value between Min to Max values, this mode is mainly used to program on/off
functions as mutes, as opposed to the push mode that has for effect to send Max value once pushed,
then Min value once released, this mode is mainly used to program momentary functions as transport
controls.
Autosend at startup : Once checked, the MIDI event assigned to the current control will be
automaticaly send at the Bitstream Pro startup. This function is useful to configure the controlled
gear/soft with the Bitstream default values.
