Glissandi and other slides when using microtonal software?

I was wondering if slides and glissandi are possible [in a midi
sequence] while concurrently using FTS or other relay programs that
utilize pitchn bend info.

On a side note what is the best way to sequence glissandi, pizzicato,
marccato, and tremelo in a sequencer (logic or cakewalk). I haven't
found a method to my liking. Sibelius has that stuff but doesn't play
it back for some reason.

***Hi Todd,

Sibelius can't play back any glissandos that go over a bar line.
It's a bug. They don't know if they can fix it without disturbing
other significant features, so we'll see if it ever gets corrected...

Hi Todd,

There are two main ways to add glissandi.

One way is to add a portamento controller with the amount of the
slide you want.

In FTS you can make an entire part portamento from Parts | More |
Portamento and Legato for parts.

If you want to do it for a single note, you need to set the controllers
in your sequencer and send it to FTS. You'll see them change in
FTS as they are sent - show the portamento / legato window
again to watch the values as they change.

The midi controller numbers are:

Portamento on / off 65
Portamento slide value 5

The on /off controller follows the Midi convention that any value
of 64 or greater is on, so to switch portamento on you send
midi controller 65 with value 127 say (or 64 often used)
and to switch it off, send any value less than 64, e.g. 0, say.

The amount of the slide controls how quickly each note slides to the next.

The thing to watch out there is that you need to switch portamento on
to use it - if you just set the slide time without switching it on as well,
it will probably have no effect.

Your synths / soundcards also needs to support portamento - some don't have it.

Also you'll need to set that part to Mono mode, either by a midi controller
message again (controller 126 to change to mono mode and 127 to go back
to poly mode) or do it in fts from the portamento / legato
dialog - that's because the portamento slide is done from the previously
played note in the channel so if it has several notes played at once, or if
they get retuned to other channels, the portamento effect gets confused
- you still get the slides but probably not from the intended note
- especially in FTS when you are also remapping the notes to other channels
as well..

Alternatively, your sequencer may generate a glissando using pitch bends - if so
FTS will relay that too, but when done that way you are limited to a slide
of at most two tones if you are using the default pitch bend range of
+- one tone, otherwise the note will need to be resounded in the middle of
the note. You'd do a two note slide by playing a note in the middle of
the range and doing a linear sweep of the pitchfrom one tone below it to
one tone above.

I've no idea how it's done in Sibelius so you'll need to find out.
In NoteWorthy Composer, which I use, you can set a portamento
controller or a linear sweep pitch bend, and both work fine.

Tremulo is also a midi effect, so that could be played just by setting the
controller again.

Parts | More | Modulation and Tremulo in FTS, and controller number 92 in your
sequencer. Modulation is vibrato which can be a pitch bend vibrato, but
can sometimes be a tremulo type vibrato too - vibrato on the flute is a tremulo
effect usually, so ones flute voice may be set up to play a tremulo for
modulation.

If you want marcatto and pizzicato, then you need a Midi sound bank with
pizzicato or marcatto voices, and to switch the voice when you get to that
point.

The Dan Dean solo strings for Giga use an ingenious method where you
can play the strings within the range of the instrument normally,
and change the style by playing a note below the natural range of the
instrument, which lets one change the style without changing the
patch. I used this in the last movement of my string quartet
near the end to do a pizzicato section.

I've just been trying to show it
and keep getting an error message. Not just for that one
but for all the mp3s at mp3.com. Anyone else been
getting this?

I gather they are in the middle of a lawsuit? anyone know
anything about it?
