"Part 1 of this series introduced arpeggiators in general and
profiled the QMidiArp application. This week we conclude our survey
with a look at two more arpeggiators for Linux musicians:
Hypercyclic and Arpage.
"Mucoder's Hypercyclic is a different kind of arpeggiator than
the others profiled in this survey. The author describes it as "...
an LFO-driven MIDI arpeggiator, gate effect, and step-sequencer for
mangling MIDI input chords." In audio terminology an LFO is a low
frequency oscillation that acts on an input signal in some
musically pleasing manner. A common musical use for an audio LFO is
the addition of a vibrato to a steady tone. The waveform of the
effect animates the tone and gives it a more lively character. The
LFO itself can be modulated, i.e. its entry may be delayed and its
intensity can be gradually increased or decreased. A MIDI LFO acts
upon an incoming MIDI data stream in a similar manner, upsetting or
rearranging the data with a musical effect."
