Suggestions for Improving Sequences

When
I evaluate students sequences, I often find that the students could
have profited by utilizing one or more of the suggestions listed
below. The suggestions are designed to make the process of sequencing
more efficient and more musical.
Suggestion
#1: Be familiar with the music to be sequenced. A great deal
of recording time and editing time can be saved by familiarizing
yourself with the score and by slowly practicing each part before
beginning to record. If possible, listen to a recorded version of
the composition. Examine the frequency range, the dynamic range,
and the timbral range of the score. Know where musical climaxes
occur so that you will be able to adjust volume levels and sound
combinations appropriately. Be aware of the articulation idiosyncrasies
of each instrument you will be emulating. In other words, try to
overcome the limitations of a keyboard and think like a violinist
when recording a violin part; think like a clarinetist when recording
a clarinet part.
Suggestion
#2: Number the measures in the score. Using a score with all
of the measures numbered will make it easy to locate specific measures
for rerecording, for editing and for playback. Be sure to number
repeated measures correctly. For example, if the first sixteen measures
of a piece repeat, measure 1 will also be measure 17, measure 2
will also be measure 18, and so on.
Suggestion
#3: Identify layered or doubled programs in your instruments
in order to conserve voice allocations. Many of todays electronic
instruments are programmed to produce thicker textures by using
layered or doubled programs. In a layered or doubled program, two
voices are used for each key played on the keyboard. This doubling
technique producers a thicker texture, but it also halves the polyphonic
resources of the instrument. For example, playing an eight note
chord using a doubled program would use 16 voices instead of eight
voices.
By
using doubled programs sparingly, you can increase the number of
voices available for other sequencer tracks. On many instruments
the only way to tell if a program is doubled is to go into program
edit mode. You can make it easy to identify doubled programs by
either adding an asterisk at the end of the names of doubled programs,
or by putting the names of all doubled programs in upper case -
for example, by changing the name Layerpiano to LAYERPIANO.
Suggestion
#4: Set the sequencer metronome at a comfortable tempo. If you
can't play the music at the indicated tempo, choose a slower tempo
for the recording process. For example, suppose that the tempo indication
for a difficult melody is 120 bpm (beats per minute). If you feel
more comfortable playing the melody at a metronome marking of 80
bpm, set the tempo indicator to 80 bpm and record the melody at
this tempo. After you finish recording, change the tempo indicator
to 120 bpm, and the sequencer will play back at the correct tempo.
Suggestion
#5: If your sequencer doesn't have an Undo function, always
make a backup copy of the original track before editing. Use the
sequencer feature called "Track Copy" to make a backup
copy of the original track. Be sure to mute the backup track. If
you accidentally damage or erase the original track, you can use
the backup copy. When you have successfully edited the original
track, erase the backup track immediately in order to avoid any
confusion.
Suggestion
#6: When recording a punch-in, start playing along with the
music before the punch-in point, and continue to play after the
punch-out point. One of the audible signs of a punch-in is a sudden
change in the phrasing of a musical line. Playing the part a little
before the punch-in point and a little after the punch-out point
will often make the punch-in less obvious by maintaining the flow
of the musical line.
Suggestion
#7: Match the dynamics of the punch-in music with the rest of
the musical line. Another audible sign of a punch-in is a sudden
change in dynamics in the middle of a musical line. Be sure to match
the dynamic level of the new musical material with the rest of the
phrase.
Suggestion
#8:Use quantization correctly and sparingly. There are two points
to consider before you use quantization. The first point to consider
is that in quantizing a track, you might produce rhythms which sound
unnatural or unmusical compared to unquantized parts of your music.
It is important to understand that rhythmically perfect music is
usually not a desired goal in musical performance. Sequences with
every track quantized usually become rhythmically uninteresting;
therefore, use quantization sparingly.
Second,
quantization will work only if you have recorded your tracks by
playing along with the sequencer's metronome. Quantizing a track
which was not recorded with the metronome will produce unpredictable
and, in most cases, disastrous musical results.
Suggestion
#9: Understand the difference between velocity and MIDI volume.
It is important to understand the difference between controlling
dynamics through velocity data and controlling dynamics through
MIDI volume. When you lower the values of note velocities, in most
cases you are lowering the volume level as well as making the tone
quality darker. When you lower the MIDI volume, you are lowering
only the volume level. This difference can be compared to a trumpet
player who plays a melody very softly during a recording session,
as opposed to a recording engineer who lowers the volume of a trumpet
part after it has been recorded. When the trumpet player plays softly,
the lower harmonics of the sound dominate, producing a darker tone
quality. When the trumpet player plays loudly, the upper harmonics
dominate, producing a brighter tone quality. Therefore, if the volume
level of the recorded trumpet melody is lowered, the notes will
be softer but the tone quality will not change. For this reason,
the editing of dynamics through velocity values is usually used
to control the dynamics of individual notes in a track; the editing
of dynamics through MIDI volume is usually used to adjust the balance
of one sequencer track with other tracks.
