The Sequencer Module allows you to create patterns of notes, which will trigger your synthesizers.
The Sequencer Module can be controlled by the Sequence Editor, and by Midi.
Working with the Sequencer Module
Creating a Sequencer Module
Switch to Module Mode, and drag a sequencer module from the module pane into the project view. When you release the mouse button, a new sequencer will be created under the cursor.
Prior to creating the module, you should ensure that the voices textbox in the module pane is set to the amount of notes that you want to be able to play simultaneously. The voice control system applies to AudioGL's internal synthesizer, and will not affect the polyphony of VST instruments.
Connecting a Sequencer Module
The procedure for connecting modules is described in the Module Mode article.
The sequencer module's output will only transmit raw notes, which are gated at the end of the note.
Gating is a method of controlling the volume of a note over time. In some instances, you will want the volume of a note to slowly decay after the note has been released. To achieve this effect, you must send the sequencer's output through an Envelope Module. The envelope will re-gate the sequencer signal, and cause it to release slowly.
Using Midi to control a Sequencer Module
Ensure that you have enabled a Midi Device in the Preferences Menu.
In Instrument Mode, simply click on an instrument. If the instrument contains a sequencer module, then it will be enabled for Midi control. If the instrument contains multiple sequencers, then AudioGL will select the sequencer which was created first. Eventually the software will be upgraded to allow the selection of a default sequencer for each instrument.
In Module Mode and Parameter Mode, click directly on the sequencer module that you want to control. A green dot will appear on top of the module. This dot denotes that the module is enabled for Midi control.
After enabling the module, press a few keys on your Midi Keyboard, and the sequencer module will play.
Recording Midi into a Sequencer Module
Enable the Sequencer that you want to use, using the procedure above.
To record Midi into the Sequencer, press the Record Enable button (keybinding: F5) on the Ribbon Bar. Then, press the Play button (keybinding: Spacebar) and press down some notes on your Midi keyboard.
You can also record notes by clicking on the keyboard to the left of the pianoroll.
Working with the Sequence Editor
Opening the Sequence Editor
There are two methods for opening the sequence editor:
In Instrument Mode, double-click on the instrument that contains the sequencer that you want to edit. The editor will appear. If the instrument contains multiple sequencer, then AudioGL will select the sequencer which was created first.
The Sequence Editor is also available in EditPage Mode. Each EditPage has it's own Sequence Editor loaded into it.
Closing the Sequence Editor
Click outside of the editor, and it will disappear.
Enabling/Disabling Note Preview
Sometimes you want to hear the pitch of a note while you are editing it. When Note Preview is enabled, notes will sound when you click on them, or when you move them up and down in the piano roll.
To disable this feature, click on the brown button as shown in Fig 2.0.
Zooming In and Out of the piano roll
To zoom in or out in the vertical direction, click the plus / minus button on the left of the editor and drag the mouse up or down.
To zoom in or out in the time direction, see the Timeline article.
Enabling/Disabling the Z and Y Snaps
To enable the Z snap, click on the Z button on the left of the editor. Your notes will now be snapped in the Z (time) direction when you create or move them. To move notes more freely, disable the snap.
To enable the Y snap, click on the Y button on the left of the editor. Your notes will now be snapped to the piano roll grid. To make notes that are out of tune, disable this snap.
Scrolling Up and Down in the Editor
You can use the ScrollBar to the right, or the Mousewheel to scroll up and down.
Creating a New Note
There two ways to create a new note.
1. Select the pencil tool in the ribbon bar (Fig 3.0). Alternatively, you can select this tool by pressing the 'x' key. Click on the piano roll and drag the mouse to create a new note.
2. Hold the 'ctrl' key, click the left mouse button on the the piano roll and drag to create a new note.
Notes can move between different pitch values. To make a note which slides from one pitch to another, simply move the mouse up or down while creating the note.
Deleting a Note
There are three ways to delete a note.
1. Select the note(s). Click the delete key on your keyboard.
2. Select the eraser tool in the ribbon bar (Fig 3.0). Alternatively, you can select this tool by pressing the 'c' key. Click on the notes you want to delete.
3. Hold down the 'ctrl' and 'alt' keys. Click on the notes you want to delete. If you have selected a variety of notes, they will all be deleted.
To select a single note, click on it.
To select multiple notes, click on them while holding the 'shift' key. Also, you can hold down the left mouse button, and drag the mouse to select notes using a bounding box.
Click on the middle of a note and drag to move the note around. Click on the left handle of a note to move the starting handle around. Click on the right handle of a note to move it around. If a variety of notes are selected, they will be modified as well.
Working with Multiple Sequencers in one Editor
When working in EditPage Mode, it is possible to load multiple sequencers in to a single editor. The different sequencers will be listed on the left side of the editor.
When editing the sequencers, you will have to select which one you want to activate. To do this, you can click on the sequencer list to the left. Another way to activate a sequencer is by double-clicking on one of it's notes in the piano roll editor.
Advanced Editing of Notes
You can use the advanced editor to create a wide range of different sounds, from vibrato, to portamento, to kick and snare drums. The advanced editor achieves this by allowing you to break each note into a series of points with different pitch values.
To open up the advanced editor, start by de-selecting all the notes in the editor. Next, double click on the note you want to edit.
The advanced note editor is very similar to the automation editor. Read the Automation Editing article for details.
Exiting the Advanced Editor
Click on the blue 'X' which is overlaid on top of the piano roll. The advanced editor will close.
