□
Parallel CPU_trigger: in this mode, could access sub_table 1-32. Some mask option must set as follow:
MATRIX/ALONE-->ALONE, SEQUENTIAL/NORMAL --> NORMAL, RESET/UNRESET-->RESET,
DEBOUNCE -->short
& for all the playing type:
EDGE/LEVEL --> EDGE, HOLD/UNHOLD -->UNHOLD, RETRIGGER/IRRETRIGGER-->RETRIGGER
In this mode, ROW1-4 & COL1 are used as (sub_table binary adress-1) input (sub_table1--32). COL4 is used as low
active enable input.
STS1, STS2, STS3 must have one selected as busy low or busy high for CPU interface strobe.
7. A8 or M16 could be mask_selected as NORMAL, SEQUENTIAL:
□
NORMAL: normal subtable mode as in item 6.
□
SEQUENTIAL:
A> if the input was triggered sequentially the device will response by one subtable by one subtable of voice_step
sequentially and cyclically, form subtable_1 to user defined subtable_n(n:1--32).
B> The relationship between SEQUENTIAL(A8/M16) and other inputs (A1-A7/M1-M15) could be mask_selected as
RESET or UNRESET:
◎
RESET : once the other inputs were triggered the SEQUENTIAL sequence will reset to subtable 1.
◎
UNRESET : sequential sequence and other inputs are independent.
8. Three status output (STS1, STS2, MODE/STS3) have following mask options
:
□
STS1:
□
STS2:
□
STS3:
a>stop high_pulse
a>stop high_pulse
b>stop low_pulse
b>stop low_pulse
c>busy high_active
c>busy high_active
d>both melody ch1 & ch2 on
d>busy low_active
at first 1/4 or 1/8 beat
e>pragrommable
e>programmable
0>disable
0>disable
1>led 6Hz or racing lamp
1>led6 Hz or racing lamp
2>led 3Hz or racing lamp
2>led3 Hz or racing lamp
3>voice dynamic 2/4
3>voice dynamic 2/4
4>melody ch1 on at first 1/4 or 1/8 beat
4>melody ch1 on at first 1/4 or 1/8 beat 5>melody ch2 on at first 1/4 or 1/8 beat at first 1/4 or 1/8 beat
5>melody ch2 on at first 1/4 or 1/8 beat 6>both melody ch1 & ch2 on
6>busy low_active
at first 1/4 or 1/8 beat
a>stop high_pulse
b>stop low_pulse
c>busy high_active
d>busy low_active
e>led 6Hz or racing lamp
f>led 3Hz
g>voice dynamic 2/4
i>melody ch1 on at first 1/4 or 1/8 beat
j>melody ch2 on at first1/4 or 1/8 beat
k>both melody ch1 & ch2 on
If both STS1 and STS2 are in 6Hz or 3Hz mode, they will flash alternatively, STS3 will flash synchronously with STS1.
Dynamic means LED will flash depending on voice signal.
For each sub-table, the STS1, STS2, STS3 could be programmed within subtable as active or inactive.
STS3 is enabled only when the MODE/STS3 is in STS3 option.
The pulse width of stop pulse: 15ms--45ms (40ms at playback speed 6KHz).
"e" item of STS1 and STS2 means the output status is controlled by program, and could be changed during synthesizing.
NOTE: The 3Hz and 6Hz depend on the ratio of current playback speed (5.3Hz to 16KHz).
the stop pulse width depend on the ratio of final playback speed.
9. The internal stop pulse feedback mask options are offered. STS1, STS2, STS3 could only feedback to one of input
pins (ROW 1-4, COL1-4). For one input could only have one output feedback to it.
