mits a logic high signal (+64 units). See also

The FlipFlop module can be described
as a “logic switch with memory func-
tion”
The module can perform
two different types of flip-
flop techniques: the ‘Set-
Reset’ and the ‘D-Type
with Reset’. To describe the
respective functions of
these flip-flops, let’s have a
look at the diagrams to the
right. See also

The Clock Divider module can be used
for dividing incoming clock pulses (or
zero-crossings) by a factor set by you.
The module transmits a high logic pulse
after it has received a user-defined number of zero-crossing transitions.

The Fixed Clock Divider module di-
vides an incoming clock signal (or bipo-
lar signal) to three fixed resulting signals.
This provides you with an easy way of
extracting 8 note, 8 note-triplets and 16th note clock pulses from a clock signal, for example.
8, T8 & 16

The Set-Reset flip-flop
works according to the
flow-chart and table to
the right. The ‘X’ in the
table means it doesn’t
matter if the value is ‘0’
or ‘1’.
A toggling signal (Tgl)
alternates between ‘0’
and ‘1’ on the positive
edge of every full Clock
period.
The D-type flip-flop
outputs what’s current-
ly on the D input on the
positive edge of each
Clk pulse - if Rst is ‘0’
(see the time diagram
to the right).
