Rev 3.1 - page 3 introduction bitstream pro is a universal hardware midi controller, fully programmable, that allows to control all software, and hardware devices that respond to midi events & messages. These midi messages can be all defined by the norm, such as control changes, nrpns, rpns, or excl...

Rev 3.1 - page 6 potentiometers / switches numbering the 3 groups (a, b, c) are shown at the top left of the above window the 3 numbers indicated on each control correspond to the control number (cc#) sent by each potentiometer or switch, depending on the selected group. These numbers are very usefu...

Rev 3.1 - page 7 shift function when simultaneously pushing midi channel up & down, the shift function is active until one of the two midi channel pushbuttons is released. Displaying switches state once the shift function is active, all the 8 switches state are displayed on lcd, as follow: the 8 swi...

Rev 3.1 - page 8 using bitstream pro in mode 1: control change this mode is a universal midi mode that allows to control all soft synths (reason, live, …) / gears with very simple midi messages called “control change”. Bitstream can generate all 128 possible control change, on all 16 midi channels. ...
Page 9
Rev 3.1 - page 9 description of “control change” midi messages “control change” midi messages are 3 bytes length, defined as follow: bn cc vv n = midi channel (0x00 to 0x0f hexa) or (00 to 15 decimal) note: midi channel 1 corresponds to n = 0 midi channel n corresponds to n = n-1 cc = controller num...

Rev 3.1 - page 10 using bitstream in mode 2: user defined midi messages this mode is used when the soft/device to control doesn’t accept standard midi messages specified by the norm. The user can assign up to 3 midi strings to each potentiometer / switch, in order to control his device(s) with bitst...

Rev 3.1 - page 11 using the waveform generator (lfo) lfo (low frequency oscillator) allows to generate sinusoidal, square, or triangle waveforms. With 3 additional potentiometers, frequency, offset and amplitude of the generated waveform are adjustable in real-time. The generated waveform can be con...

Rev 3.1 - page 12 offset adjustment a potentiometer is dedicated to the offset (dc value) of the generated wave. It allows to modify this value from 32 to 96, and can be tweaked dynamically, in order to produce real-time midi effects. The following figure illustrates offset adjustment on a sinusoida...

Rev 3.1 - page 13 lcd example when configured as an externally synchronized lfo, if no external midi clock is detected, then the following lcd screen should appear: the above screen indicates that the lfo doesn’t generate data until a valid midi clock is detected. Internal lfo synchronization the ri...

Rev 3.1 - page 14 using the snapshot scene memory this button is used to save / restore value of all 48 controls (40 potentiometers + 8 switches) to / from memory. Pushing this button during 3 seconds allows to save the state of all 48 controls in memory depending on the selected group pushing this ...
