LOGIC GROUP
These modules can generate and combine logic signals in a number of different ways. A logic output
signal will have one of only two states: a logic
HIGH
, which always corresponds to a value of +64 units
and a logic
LOW
, which always corresponds to a value of 0 units. But the edges of logic signals can be very
important as well, edges are when a logic signal changes from
LOW
to
HIGH
, which is named the positive
edge or from
HIGH
to
LOW
which is named the negative edge. Edges can specify a precise moment in time
when you want something to happen, like playing a note or advance a sequencer to its next step.
Triggering will always use the positive edge of a logic signal and doesn’t care how long the logic signal
stays in its
HIGH
state.
Getting everything in perfect timing means many times to delay the edges of logic signals to moments in
time specified by e.g. the positive edges of the pulses in a master clock signal. In this group you will find
modules that can help you to synchronize events to a master clock.
Note that synchronization is very important in music. Still, many times it is not at all that easy and obvious
how to do it. In fact synchronization is an art by itself that takes some time to master. Our advise is to
take the time it takes and learn it one step at a time. As you will find out this is also how logic works; step
after step.

signal input(s). If you input an audio signal, the color of the
input(s) and logic signal output(s) change color to orange to indicate that the module has adapted
itself for audio rate bandwidth. Any positive value in the input signal will be interpreted as a logic
HIGH
signal on a logic input. Any negative value or a value of zero will be interpreted as a logic
LOW
signal on
a logic input. So, if the input signal is not already a logic signal, it will first be transformed at the input to
a logic signal according to the previously describe ‘rules’ before being used internally in the module.

clocked signal input(s). A clocked signal input with a single
arrow next to it will only react when an input signal changes from a logic

to a logic

state. This moment is also named the positive edge of the clocking signal.

R
ST
INPUT
Some Rst signal inputs have a barred arrow next to their input connector. This tells that the
module has a delayed function, meaning it will wait for the positive edge on another signal input
before resetting the module. In practice it means that the actual reset is synchronized to the clock pulses
on the Clk input.

INPUT
(
LEVEL
CONTROLLED
)
A level controlled Reset signal input has no arrow and is used to reset a module to its initial value
on the moment when a logic
HIGH
reset pulse arrives and then halts or disables the module until
the reset signal has returned to a logic
LOW
level. So, as long as there is a logic
HIGH
level on this input
the module will stay inactive in its default state.
