Stereo Pan

Intro

Set stereo pan positions for each part for a more immersive experience...

You can use this to place individual instruments in different locations to get a more immersive experience. For instance in a string quartet, the violin is to left, then second violin, then viola then cello in that order.

See also #Standard orchestral layout below.

How to show this window

Ways to show this window include: the Pan button in many of the main window tasks, or Parts | More | Stereo Pan...

Keyboard shortcut Ctrl + 9 or Ctrl + Pan

How to use this window

Highlight the part you want to pan. Then set a value in the text box below the Value column.

You can also use one of the presets. Set the number for:

Number of parts to set for the left right buttons

to a number higher than 1, and some buttons will appear with presets left right, all to centre and (if number of parts to pan is more than 2) first part to centre)

To pan hard left, use 0 and to pan hard right set the number to 127. Often even when a note is panned hard left, you may hear a bit of the note in the right speaker. This is more natural sounding, because if you listened to a performance with the instrumentalist far left, you would hear some sound in your right ear. Other synths will give no sound at all in the right speaker when the sound is panned hard left. If you find the separation of the parts too harsh, you may feel the recording is more realistic sounding if you make the range just a touch less, say 10 to 117 or some such.

For this reason the presets pan from 10 to 117 instead of 0 to 127. You can change this by varying the the Range for buttons to set pan.

Another way to vary the pan automatically is to use auto pan.

auto pan options

The auto pan option to pan by part pans automatically so that the first part is to the left, and the last part is to the right, which makes the music more immersive if the parts haven't been given pan positions individually.

The options to pan by the position in the chord, and by position in scale are sometimes of interest - they create an effect where the notes move about in position within a single phrase or chord. Keyboard music sounds like this from the point of view of the player or a listener in a suitable position close to the keyboard - the notes are spread out spatially with the low notes to the left and the high notes to the right.

Composers sometimes use panning effects like this, creating an aural impression of a performer floating about in space.

It's also useful if you want to distinguish notes of a chord by their spatial postion. The Lissajous patterns for two note chords correspond to the patterns you get if you have hard panning, and the sounds for the left and right speakers are used for the two axes of the Lissajous curve.

Orchestral layout

In a standard orchestral layout, the strings follow a similar layout to a string quartet. Then, percussion, horns, clarinets, piccolo, flutes are mid left, trombones, trumpets, bassoons, oboes and cor anglais are mid right, tuba and double bass are far right.

The layout varies, and has also changed historically.

Part

Select the part you want to highlight

The part number can be used in many places in Tune Smithy, and is the equivalent of a Midi Out channel in FTS. You can't use Midi channels directly as the notes for a single part often have to be relayed to many different channels for retuning purposes.

To make sure that FTS does the channel mapping optimally for your current out device(s), run the Out Devices Capabilities Wizard in the Out menu. If you want to customise which channels are used in detail, use Midi Output Channels for Parts and Polyphony (Ctrl + 60)

What is a part

In a program without instant pitch bend retuning, this window would just show the midi out channels. However when you use pitch bends to change the tuning of the scale, it is the software that deals with the midi out channels rather than the user. The user doesn't work at that level at all (normally). So we need another way of working with instruments, volumes etc, so we need the Parts to take the place of channels.

Why are parts needed

This is why: To play a chord, say the just intonation major chord 1/1 5/4 3/2, using midi pitch bends, you have to play the notes on different output channels - for instance the 1/1 may be played on channel 1, the 5/4 on channel 2 and the 3/2 on channel 3. That's because the pitch bend is set for a channel as a whole in MIDI (normally anyway). This happens automatically in FTS, notes change channel frequently to let them be retuned correctly and smoothly. So notes of a single chord or melodic phrase will often be spread out over several midi channels. This sort of thing is something software can be programmed to keep track of in a routine (though complicated) fashion, but is mind boggling for a user of the software.

So as a user of the software, you need something else to work with rather than Midi out channels, and that's where the Parts come in. You just set up a part much as you would do for a channel in twelve equal type Midi work. You set it up with a midi instrument, controllers, pan position etc. You don't need to worry about the techy details of which midi out channels to send all the pitch bends and other messages to. FTS keeps track of all those details for you. The software will send the notes on whatever channel is appropriate, depending on its records of which notes have been sent on them previously - and it will also set the pitch bends accordingly for each channel, and also send any controllers and other messages to the correct channels as well.

What if I want to see which midi channels are used by the parts

However, if you are interested to see where the notes did get relayed to, just show the Out | Notes in Play - Midi Out (Ctrl + 47) window. In the More version of that window, you will see the notes currently in play for the part listed by output channel, with the pitch bends in cents for each channel.

You will find that notes that need the same pitch bend often share channels, for instance all the 5/4s may play on one channel, or notes a quarter tone sharp or flat or whatever may all get played on the same channel - as long as they have the same requirements in terms of other controllers such as pan position etc.

So for instance, notes in twenty four equal (quarter tone) only need two channels, one for the "standard" 12-et notes and one for all the notes a quarter tone sharp (or flat). Notes in any pentatonic scale only need five channels at most for the pitch bends, a seven note scale only needs seven channels at most, and a twelve note octave repeating scale needs only twelve channels to play all the notes (if the controllers and pan positions are the same) - less if there are any 12-et intervals in the scale.

Voice

Shows which instruments play which parts.

To change the instrument for a part, use the PARTS window. Then highlight the part to change, and select a new instrument from the Instruments menu, the Wave shape player, non melodic percussion, or the custom voices.

You can highlight more than one part - click on the first part in the Parts (Ctrl + 9), and then drag with the mouse to seelct more than one part. Or use Shift + click on the last part or Ctrl + click to add just one part to the highlight.

Then you will be able to change the instrument for all the highlighted parts at once. If you hold the SHIFT key down when you select an instrument, then you can select it, and the instruments that follow it in the menu into all the highlighted parts in the parts window - that's useful if you want to try out several instruments at once.

You can select non melodic percussion into any part. The non melodic percussion needs to be played on a General Midi synth or sound card - most sound cards are GM, but many specialist musicians synths are not. The non melodic percussion notes all get played on the Midi output channel 10 (normally).

You can select melodic instruments into part 10 as well, they will be relayed to other channels instead of channel 10 for a GM synth.

When you play notes from Midi IN, you would expect notes sent to FTS from channel 10 to play non melodic percussion. That's what happens if you have In | Options | Select Parts by Input Channel - then FTS will treat all notes from channel 10 as non melodic percussion instrument selections.

You can customise the way FTS deals with non melodic percussion using In | Options | More Midi In Options. (Ctrl + 92) and Out | Options | Out Devices Capabilities (Ctrl + 106).

A quick way to set up your Midi Out settings appropriately for your current midi Out device is to run the Out | Out Device Capabilities wizard.

Pos in arp

Pansleft to right in arpeggio position order, back to left at repeat

Pos in chord

Pans the notes in current chord left to right in order played...

As you play the notes of the chord move around so that at any time, the entire current chord gets panned from left to right in the order the notes were played.

When you play a single note it is panned to the centre. If you add a second note, the first note gets moved to the left and the second note is played to the right. Adding a third note moves the second note to the centre and the third note then goes to the right and so on.

The same happens when you release the notes, all the notes still in play are auto panned left to right in the order they were originally played.

Stand. Orch.

Auto pans any recognised instruments to the standard position in an orchestra...

This is done by the instrument name, so e.g. if the instrument is shown as a violin in the parts window it will pan hard left, if shown as a conatrabass, hard right. Any percussion is panned mid left with this layout. Unmapped instruments are panned left / right depending on the part number.

Orchestral layout

In a standard orchestral layout, the strings follow a similar layout to a string quartet. Then, percussion, horns, clarinets, piccolo, flutes are mid left, trombones, trumpets, bassoons, oboes and cor anglais are mid right, tuba and double bass are far right.

The layout varies, and has also changed historically.

In - Yes

When selected, Tune Smithy responds to midi in pan change messages...

Usually selected. A midi in pan change message will switch off auto pan.

You may need to switch this off to auto pan in some situations. For instance if you return a midi clip in the retuning midi player or retune the output from notation software then it may set pan positions for the instruments and you may need to set FTS to ignore those before it can auto pan the notes or parts.

To switch it off just when auto pan is switched on, select the No In for Auto Pan option - which shows up when any of the auto pan options is switched on.
