Sequencer
Controller View
The Controller View, in this sequencer, shows
lines for a particular sort of event or controller
as you go measure by measure through the song,
for a particular track, where the height of each line
indicates the value used.
The number of lines shown side by side, the density as it were,
can be set whenever one wants to change it.
Here it's at about 20-25 controllers/beat.
It can be a lot more dense than that (and of course, this
controller window can be maximized to be much larger, too).
A controller like pitch bend can go from -8000 or so
(actually, it's 8191, to be precise),
to +8000, where most others are just single byte (even just 7 bit)
values which cover only 0-127.
The value at the cursor, that little pencil looking thing,
is shown at the bottom, as you can see.
It's about midway between the 2nd and 3rd beat of measure 6, timebase
here of 120, up at about 4000.
Now that 4000 or so could mean anything.
Typically, though, it'll be a half-step, and 8000, a whole step.
So ~8000 at the bottom, to ~8000 at the top, is two whole notes.
If you want more, most synthesizers can give you more,
by making the scale larger, and the resolution more coarse.
Instead of 8000 being a whole note for the pitch bend, you
can use SysEx or RPN to set it to three semi-tones, or two whole notes,
or five semitones, three, four, five whole notes, whatever the
synthesizer will recognize; in which case the spread from minus ~8000 to plus
would exceed an octave, which is a lot of pitch bend.
The actual display, here, is pretty typical for pitch bend,
with a quick ramp up, a brief hold, and quick fall off, with
smaller 'bumps' for vibrato.
I just drew straight lines with the mouse.
And I used a curve to bend up, ramp up, to the first bit, leading
into the second beat of bar 6.
Now assuming there's actually a note starting a little before the
second beat, playing out the same channel as the
pitch bends (this sequencer probably should show the channel
used by the events as well, in this view), then it
will slide up, and then sort of ratchet down.
Maybe one would prefer a slower bend down a full note.
Just draw another curve:
Release:
And viola! There it is.
A whole sequence of pitch bends reshaped in just a few seconds, made
to order.
You can show most anything in this view, with these vertical
lines.
You can check out the modulation controllers, say:
Where this is pretty typically what you'd see for mod controllers,
which run from 0 at the bottom to 127 at the top;
a staggered step up and down, giving something like the vibrato
effect, noted above, using the pitch bend.
Or you can just show the velocity of the notes on a track:
And this can be really handy for a final production and
mix, as you play the song, and just sort of move up or down a bit
the note 'volume', or velocities, track by track,
so that ultimately the instruments kind of all
fit together just right.
You literally can just draw a curve to reshape the velocities
for a whole run of notes, in a second.
It makes it very easy.
