Audio and MIDI sequencer


Nowadays, we define sequencer , a program that can work on multiple tracks containing audio and MIDI. The operation is essentially what we have already described for any multitrack audio editing program.

We add that normally a sequencer relies on an external editor for editing of individual audio tracks. In the case of MIDI, however, the editor are usually even three, each of which permits to work at a different level. There is a score editor , which allows you to view your music in the form of notes on the musical staff.

There is an editor bar, also called ” a player piano roll “, in which the musical notes are represented in the form of colored bars with a length proportional to the length, and the position of which along the vertical axis represents the height of the sound.

And finally, there is a pure text editor, where the MIDI file is displayed as a simple sequence of data. It is evident that each editor works in a different level: the score is used to macroscopic changes of the composition, the one bar for details, while the ‘ text editor allows to programs to create musicintervene on the individual dato.È clear that the main purpose of a sequencer is music composition, but nothing prevents exploit its features to other kinds of audio editing. Most sequencer includes features audio capture and even CD burning.

To play the sounds, the part of the MIDI sequencer can exploit the sound generator sound card, an external device, or even a musical instrument virtual, usually in VST format (see box). Among the sequencer amateur level, the most widespread and popular is Cubasis VST, smaller version of the famous professional software Cubase by Steinberg .


Here’s what you need to do to add to your video a soundtrack composed of music, sound effects and voice-overs!


Now that you know everything there is to know about the various types of audio files, we see in practice how to add sound to our video.

We launch Pinnacle and reload our project.

First of all, we look at the situation: we had already mounted the sequence of scenes, add fades and titles. The video is pretty much already packed, but if we see it again we note that the audio “original”, that is what captured by the camera, leaves much to be desired.

Apart from the quality not excellent (the microphones of the camera do what they can; if you want to capture good audio environment, you have to use external microphones), the problem lies in the continuity, even in its absence: the assembly is in fact composed of clips were shot at different times, and then between a clip and the other there will be “jumps” in the sound. The best thing, if the audio was not recorded in a workmanlike manner , is lowering the level, and cover it with a soundtrack packed “ad hoc”. The original audio we can make him feel, alzandone the volume, only in those areas where it is important: for example, if seen as a bell sounds, the original audio will dominate the soundtrack added later. The same if a person speaks toward the goal: if you do not hear the voice, the effect is obtained goldfish …

Once you have chosen and enter the music, you can decide if it is the case to complete the sound with narration or voice-over (in English, “voice over”). In case you decide to add this last element, know that you’ll have to do some ‘of preparatory work: first of all, you’ll have to write the script, short text to be recorded.

Keep in mind that in a minute you read about 1500 characters, so do not get caught up too. As for the style, in Italy are all the rage style “Tourists by chance “, especially for travel videos, and” Responded “for all others. Both are not easy to reproduce, and require a decent effort in drafting the initial text. Among the possible alternatives, the style “Quark” (“We followed a specimen of this curious biped in the day that happens its transformation from a free homo homo married”).

Before recording, you do some reading test before the video to see if the times match (in the jargon, “dry run”). When everything is in place, recorded. For this operation are very comfortable headphones with built-in microphone, but if you can afford a real microphone “vocal “than those used by the singers, so much the better.

Remember that many microphones have a nasty habit of recording not only your voice, but also any ambient sounds; then choose to record a quiet and at night, otherwise you will be amazed, listening again to the recording, the amount of background noise. The fact is that we are used to these noises, and we do not notice it, but the microphone will capture the same. One final note: in these pages we show you how to add music and narration directly in Pinnacle, but if you want you can record it all with one of the programs that we have described in the preceding pages, apply various effects, adjust the volume, and the only end import the audio file obtained in the editing program, synchronizing it with the video.


To work on the sound Pinnacle, must first be in edit mode, then click on the speaker icon on the left; you will see that they will disappear from the album and video clips, and appear all music files available on the PC, divided into various folders. At any time, you can open the audio tools.
