Bastl CV Trinity Manual

technical details

� 14HP
� 35mm deep
� PTC fuse and diode protected 16 pin power connector
� requires +5V on bus board
� current consumption: +12V: <5mA, -12V <5mA, +5V: <35mA
Before connecting the ribbon cable to this module
disconnect your system from power !
!
Double check the polarity of the ribbon cable and
that it is not shifted in any direction. the red cable
should match the -12V rail both on the module and
on the bus board !
please make sure of the following
� you have a standard pinout eurorack bus board
� you have +5, +12 and -12 power rails on that bus
board
� the power rails are not overloaded by current
Although we put protection circuits in the device,
we do not take any responsibility for damages
caused by wrong power supply connection.
After you connected everything, double-checked
it and closed your system, so no power lines can
be touched by hand, turn on your system and test
the module.
instruction
)
CV Trinity has 6 independent channels for CV generation.
The generated signals are in the 0-5 volts range. Each
of them can be set to AUTOMATION (red), LFO (green)
or ADSR (blue).
)
Use the SELECT buttons to select a channel to edit. The
layout of the 3 big buttons corresponds to the output
connector layout. The 3 big buttons select the column
and the small button select which row you are editing.
The selected channel is indicated by the LEDs.
)
The SELECT OUT connector outputs a copy of the CV from
the channel that is selected for editing. The current signal
is indicated by an LED.
)
Pressing the mode button changes between the modes.
The mode of the selected channel is indicated by the color
of the RGB LED. In each mode the knobs have different
functions which are indicated by the front panel print.
)
Each channel also has a CV /gate /clock INPUT. The
function of these inputs depends on the selected mode
and its settings.
)
Clk IN is used by AUTOMATION or LFO to synchronize to
a master clock.
)
Clk OUT outputs a clock signal from the built-in clock
generator. The clock generator frequency can be adjusted
by holding the FN button and turning the top knob. Clk
OUT is normalized to Clock IN.
)
The FN button lets you to access additional settings for
each mode. While you hold the FN button the SELECT
buttons show the setting information bits. Please refer
to the mode description for details.
)
The record button is used during automation to record
knob movement. If you press the record button while
holding the FN button CV Trinity saves all settings for
all channels into a preset.
)
Six jumpers on the back side of the CV Trinity select
whether the CV input should react to 0-5V (jumper
inserted) or 0-10V (jumper not inserted). This can be
set for each channel individually.
)
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.
