Low Pass Filter
Synthesizers are often equipped with a low pass filter. A
low pass filter dampens all frequencies above its cutoff
frequency. Frequencies below the cutoff point are not
affected.
MIDI
The acronym MIDI stands for "musical instrument digital
interface." It was developed in the early 1980s so that
diverse types of electronic musical instruments by diffe-
rent manufacturers could interact. At the time a commu-
nications standard for heterogeneous devices did not
exist, so MIDI was a significant advance. It made it pos-
sible to link all devices with one another through simple,
uniform connections.
Essentially, this is how MIDI works: One sender is
connected to one or several receivers. For instance, if
you want to use a MIDI keyboard to play Nave, then the
keyboard is the sender and Nave acts as the receiver.
With a few exceptions, the majority of MIDI hardware
devices are equipped with two or three ports for this
purpose: MIDI In, MIDI Out and in some cases MIDI
Thru. The sender transfers data to the receiver via the
MIDI Out jack. Data are sent via a cable to the receiver’s
MIDI In jack.
MIDI Kanal
This is a very important element of most messages. A
receiver can only respond to incoming messages if its
receive channel is set to the same channel as the one the
sender is using to transmit data. Subsequently, the sender
can address specific receivers individually. MIDI Chan-
nels 1 through 16 are available for this purpose.
MIDI Clock
The MIDI Clock message sets the tempo of a piece of
music. It serves to synchronize processes based on time.
Modulation
A modulation influences or changes a sound-shaping
component via a modulation source. Modulation sources
include envelopes, LFOs or MIDI messages. The modula-
tion destination is sound-shaping component such as a
wave position or filter.
Note on / Note off
This is the most important MIDI message. It sets the pitch
and velocity of every generated note. The time of arrival
is simultaneously the start time of the note. Its pitch is
derived from the note number, which lies between 0 and
127. The velocity lies between 1 and 127. A value of 0
for velocity is similar to "Note Off".
