USER MANUAL
Selection of the MIDI Delay
This parameter allows the user to insert a delay after each MIDI
Message generated by the control concerned.
It is generally used with the synths receiving from exclusives systems
sent by the Bitstream 3X, in order to allow time to treat them.
This parameter should be kept weak in order to have the best fluidity and shouldn’t be raised unless
the synth or the software requires the insertion of a delay
The different choices available are:
0 (no delay)
30 ms
60 ms
90 ms

Curve Models
This parameter defines the behaviour of the different analog controls
on the Bitstream 3X. The model of an analog control
can vary in different ways, among which:
Linear (default mode)
Inverse linear (the control at maximum generates the minimum value)
Logarithmic
Inverse Logarithmic
Random (The control generates a random value no matter what its position)
User 1 and User 2 (The user redefines the sent value at each position of the control)
These different modes are described in this manual, see the dedicated chapters.

Checksum Management for exclusive systems
The Bitstream 3X is capable of generating exclusive systems
(SYSEXs) in user mode. Certain synths or software capable of
receiving sysexs require the reception of an integrated checksum
in the sysex, in order to proceed to an eventual error correction.
A checksum is an integrated number in the end of a sysex, just before the end marker sysex F7h. This
number is calculated by a known algorithm, defined by a standard. This calculation is the sum of the
octets preceding the checksum, modulo 128.
From the controlling synth, the position of the first byte which needs to be taken into account for the
calculation of the checksum (called « checksum first byte position ») can vary, so that this first octet is
configurable on the Bitstream 3X, in order to make it compatible with all the synths in the market.
If the value of this parameter is 0, the Bitstream 3X will not integrate the checksum in the generated
sysex, if the value is different than 0, it will correspond with the position of the first byte in the MIDI
chain to be taken into account for the checksum.
