Sequitur makes use of filters to control the flow of MIDI data on your system. Take a look at all available MIDI devices and filters in your system by selecting Windows --> Filters. Through filters will be discussed later in this guide. Note that your filters window may vary from the picture below depending on what MIDI devices you have connected.
3. Creating Notes |
3.2. Using your primary mouse button (by default the left on two and three button mice), place a few notes down anywhere on the grid. If you have speakers connected to your sound card, you should hear the notes played as they are placed. Note the song window updates to display the new notes.
Sequitur includes four tools to edit MIDI data.

Pencil tool. Used to place notes in a track. Single clicking on a note with the pencil tool will select the note while clicking and dragging will move the note around in the track. |
![]() |
Select tool. Used to select notes in a track. Clicking and dragging will box an area to be selected. |

Eraser tool. Click and drag to erase notes. |
The track window contains its own set of transport controls. These controls only play the visible area of the track.
![]() |

Loop Mode. Toggle loop mode on or off. |
4. Add a Filter |
From the filters window, select the Echo filter and drag it to the final slot of the edit pipeline in the 'Be MIDI Synth - 1' track window. At this point, any notes you place down will have the Echo filter applied to them. Any number of filters may be placed in the pipeline, and will be applied to all new notes added to the track. Filters placed in the edit pipeline will apply only to that track. | ![]() |
Place down a few notes to see (and hear!) how they're affected by the Echo filter.
5. Change Instruments |
6. Add Drums |
6.2. Rename this track 'Drums' by single-clicking on the text 'Be MIDI Synth - 2' in the song window and entering a new name. Hit return to accept the change. Double-click to open up the track window for the Drums track as you did for the first track (3.1.)
6.3. Click on the first button (note duration) under the Quantize label, and select sixteenth notes (1680 ticks). Create a few sixteenth drum notes using the pencil tool. Click the Play Song button to hear both tracks together. | ![]() |
Notice that the notes for the previous track appear grey, giving you a frame of reference for the new notes in this track. The Saturation knob can be used to lighten or darken the notes of other tracks. | ![]() |
6.4. In the filters window, drag the icon for the Example filter to the first slot of the output pipeline of the 'Drums' track. This will apply the Example filter to all notes in the Drums track. From the song window, click the Rewind button, then the Play Song button to hear both your tracks, and note the effect added to Drums by the Example filter.
Click on the M (mute) to the right of 'Be MIDI Synth - 1' to mute the first track, and hear the Drums alone.
7. Record a New Phrase |
7.1. Find the track which has the MIDI input filter that will be receiving MIDI events. In this example, we're using the first MIDI Oxygen 44 track.
7.2. Enable the track for recording by pressing the R (record) button to the right of the track name.
7.3. Prepare the song for recording by pressing the Record button in the song's transport controls.
7.4. Click and drag the song position in the measure control, placing it where you want recording to being. Press the Play Song button to begin recording. The events will appear as you're playing. When Record mode is enabled, the song will not automatically stop. Press the Stop button when you're finished recording.
