Requested dynamic range of selected MIDI note can be set
by "Level Slope Min" and "Level Slope Max" parameters. "Level
Slope Min" set output level of generator signal if "Velocity" is 1
and "Level Slope Max" set output level of generator signal if
"Velocity" is 127. For all others values of "Velocity", output level
of generator is linearly interpolated between "Level Slope Min"
and "Level Slope Max" levels.
Fig. 3 – Setting of tone generators dynamics
Note: TR-808 tone generators reaction to the MIDI velocity
is different for each particular drum sound. It corresponds to the
original "Accent" setting range. Some of the sounds have large
accent sensitivity range, some of the generators provide only
minor changes with the higher accent level. This is done by the
TR-808 construction and it is not possible to change it without
major TR-808 circuitry modification.
3.1.2. Program (Patch) Change commands
MIDI Program Change command is used to select TR-808
MIDI control/synchronization via MIDI bus or controllers on TR-
808 panel. Interface uses program numbers 1 (00h) to 13 (0Ch),
all others numbers are ignored. Program No. 1 is default on
every TR-808 start-up.
In dependence
combination of control/synchronization modes is used - see table
2. Note that tone generators of TR-808 can be triggered by MIDI
notes and by internal sequencer of TR-808 simultaneously and
