Bastl CV Trinity User manual


CV Trinity hs 6 independent chnnels for CV genertion.
The generted signls re in the 0-5 volts rnge. Ech
ofthem cn be set to AUTOMATION (red), LFO (green)
orADSR (blue).

Use the SELECT buttons to select  chnnel to edit. The
lyout of the 3 big buttons corresponds to the output
connector lyout. The 3 big buttons select the column
ndthe smll button select which row you re editing.
Theselected chnnel is indicted by the LEDs.

The SELECT OUT connector outputs  copy of the CV from
the chnnel tht is selected for editing. The current signl
is indicted by n LED.

Pressing the mode button chnges between the modes.
The mode of the selected chnnel is indicted by the color
of the RGB LED. In ech mode the knobs hve different
functions which re indicted by the front pnel print.

Ech chnnel lso hs  CV/gte/clock INPUT. The
function of these inputs depends on the selected mode
nd its settings.

Clk IN is used by AUTOMATION or LFO to synchronize to
mster clock.

Clk OUT outputs  clock signl from the built-in clock
instruction
genertor. The clock genertor frequency cn be djusted
by holding the FN button nd turning the top knob. Clk
OUT is normlized to Clock IN.

The FN button lets you to ccess dditionl settings for
ech mode. While you hold the FN button the SELECT
buttons show the setting informtion bits. Plese refer
tothe mode description for detils.

The record button is used during utomtion to record
knob movement. If you press the record button while
holding the FN button CV Trinity sves ll settings for
llchnnels into  preset.

Six jumpers on the bck side of the CV Trinity select
whether the CV input should rect to 0-5V (jumper
inserted) or 0-10V (jumper not inserted). This cn be
setfor ech chnnel individully.

Two jumpers in between the programming headers
assurecommunication between the circuit boards. Both
of them have to be inserted (vertical position) for proper
operation. In case you would like to hack the Trinity or
upgrade the source code you can use the standard FTDi
USB adaptor pin headers for programming the interface
(top) board and the CV (bottom) board. The “disconnect
for programming” jumpers have to be unplugged for
proper upload procedure.

Expansion pin headers are here for connecting expansion
modules. please follow the side marking on the
appropriate expansion boards.

Before connectin the ribbon cable to this module
disconnect our sstem from ower !
Double check the olarit of the ribbon cable and

Although we put protection circuits in the device,
we do not tke ny responsibility for dmges
cused by wrong power supply connection.
After you connected everything, double-checked
it nd closed your system, so no power lines cn
be touched by hnd, turn on your system nd test

AUTOMATION
Automtion is  32 step knob recorder with djustble
mount of liner interpoltion. Hold the record button
nd use the TOP knob to enter voltges into the memory.
Pulse signl on Clock input dvnces to next step. The
LEFT knob djusts the mount of smoothing. When it is
fully to the left, the signl is stepped nd when fully right
it is linerly interpolted. The RIGHT knob djusts how
mny of 32 steps re used.
Holding the FN button nd pressing the big SELECT
buttons gives you ccess to more settings. The leftmost
big button sets whether the utomtion is clocked by
themster clock (light ON) or if it is expecting  clock
on the selected chnnel input (light OFF). The middle
big button clers the whole memory to 0 volts. The
rightmost big button selects whether the number of
steps set by the RIGHT knob llows ny number including
odd numbers or if it filters them out nd lets you set the
number of steps only to 1,2,4,8,16 or 32 steps.
LFO
LFO is n dvnced low frequency oscilltor with
wveshper nd mny extr fetures including  loopble
clocked rndom genertor with smoothing.
In the defult settings, the TOP knob sets the LFO rte.
In synchronistion mode it sets the divider of the clock
input to which the LFO will synchronise nd in pingble
mode it sets the reltive phse shift of the ping input
clock.
The RIGHT knob selects the wveform/ type of the LFO.
In order from leftmost to rightmost the wveforms re:
tringle, sw, rmp, flopping tringle, flopping sw,
stepped rndom, looped stepped rndom. The stepped
rndom mode is either clocked by the LFO rte, or by the
divider of the clock input, when in synchronistion mode.
The looped stepped rndom mode tkes the lst 32 steps
of the stepped rndom pttern nd loops them.
features
The LEFT knob sets wveshping or smoothing for the
stepped rndom wve. For rmp wveform it cts s
bit reducer nd for the stepped rndom wve it works
s smoothing. For ll other wveforms it cts s XOR
modultion. This mens tht the wveform is XORed with
number from 0-255 set by this knob. XORing with 255
inverts the wveform.
Holding the FN button nd pressing the big SELECT
buttons gives you ccess to the following settings.
The leftmost big button sets whether the LFO is free
running (light OFF) or synchronised to the min CLK
IN. When synchronised, the TOP knob sets the divider
specifying how mny clock pulses one LFO period should
lst. The leftmost chnnels synchronize with no phse
offset to the clock, the middle chnnels synchronize with
 90°phse shift nd the leftmost chnnels synchronize
with  180°phse shift. This cn be used for vrious
qudrture effects.
The middle big button sets whether the CV input is
ffecting the LFO rte proportionlly with the voltge on
tht input (light OFF) or if it works in pingble mode. This
mens tht if you send t lest two pulses to this input,
the LFO sets its rte to the time in between these pulses.
When this setting is ctivted the synchronistion to the
min clock is dectivted nd the TOP knob ffects the
phse shift reltive to the clock on CV input.
The rightmost big button selects the rnge of the LFO. It cn
be slow with periods in the rnge of 2 min to 200ms (light
off) of fst: 2 s -10 ms. This pplies only to the free running
LFO (both middle nd leftmost lights re turned OFF).
ADSR
ADSR uses the CV input s GATE input for triggering
the envelope. The TOP knob sets ttck (1ms—10s). The
LEFT knob sets sustin or hold time, when in hold mode
(1ms —10s). The RIGHT knob sets both decy nd relese
time (1ms — 10s).
Holding the FN button nd pressing the big SELECT
buttons gives you ccess to more settings. The leftmost
big button cn turn on HOLD mode (light ON). In hold
mode, the envelope is in ttck - hold - relese mode.
Theenvelope resets the full cycle nytime there is rising
edge from  clock pulse t the GATE input.
The middle big button sets whether the envelope is in
LOOP mode (light ON). In the this mode, the GATE input
resets the envelope cycle.
The rightmost big button selects whether the envelope
isliner (light ON) or exponentil (light OFF).
