frequency. A high pass filter in turn dampens the
frequencies below the cutoff. The band pass filter allows
only those frequencies around the cutoff frequency to
pass, all others are dampened. A band stop filter does just
the opposite, i.e. it dampens only the frequencies around
the cutoff frequency. The most common type is the low
pass filter.
Filter Cutoff Frequency
The filter cutoff frequency is a significant factor for filters.
A low pass filter dampens the portion of the signal that
lies above this frequency. Frequencies below this value
are allowed to pass through without being processed.
High Pass Filter
A high pass filter dampens all frequencies below its cutoff
frequency. Frequencies above the cutoff point are not
affected.
LFO
LFO is an acronym for low-frequency oscillator. The LFO
generates a periodic oscillation at a low frequency and
features variable waveshapes. Similar to an envelope, an
LFO can be used to modulate a sound-shaping
component.
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 '80s so that
diverse types of electronic musical instruments by
different manufacturers could interact. At the time a
communications standard for heterogeneous devices did
not exist, so MIDI was a significant advance. It made it
possible 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 computer to play the Pulse, then the
computer is the sender and the Pulse acts as the receiver.
With a few exceptions, the majority of MIDI 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.
