How Do I Convert My MIDI Sequence to Audio?

MIDI (Musical Instrument Digital Interface) is an essential tool in modern music production, allowing musicians to create, edit, and play complex compositions. However, since MIDI files only contain performance data (such as which notes to play and how), they don’t produce actual sound on their own. To share or finalize your music, you often need to convert MIDI sequences into audio files like WAV or MP3. Here’s how to do it.

Why Convert MIDI to Audio?

Converting MIDI to audio is useful for several reasons:

  1. Playback Compatibility: MIDI files require a compatible instrument or software to generate sound, while audio files can be played on any device.
  2. Preserving Sound: Audio files capture the exact sound as it’s produced, including effects and instrument choices, ensuring consistent playback.
  3. Sharing and Distribution: Audio files are universally accessible, making them ideal for sharing your music on streaming platforms or social media.

Methods to Convert MIDI to Audio

There are multiple ways to convert MIDI sequences into audio files, depending on your setup and tools. Below are some common methods.

1. Using a Digital Audio Workstation (DAW)

Most DAWs allow you to export MIDI tracks as audio files. Here’s a general process:

Step 1: Load Your MIDI File

  • Open your DAW and import the MIDI file.
  • Assign virtual instruments to each MIDI track to generate sound.

Step 2: Add Effects and Adjustments

  • Customize the sound by adding effects like reverb, delay, or EQ.
  • Adjust volume and panning to balance your mix.

Step 3: Export as Audio

  • In your DAW’s export menu, choose your preferred audio format (e.g., WAV, MP3).
  • Render the MIDI performance as an audio file.

Popular DAWs:

  • Ableton Live
  • FL Studio
  • Logic Pro
  • GarageBand
  • Cubase

2. Using a Virtual Instrument or Synthesizer

If you’re using a standalone virtual instrument or synthesizer:

Step 1: Load the MIDI Sequence

  • Import your MIDI file into the software.

Step 2: Adjust Settings

  • Choose your desired instrument sound and apply effects if available.

Step 3: Record the Output

  • Use the software’s export function to save the audio, or record the output in a DAW.

3. Using MIDI to Audio Conversion Software

Some dedicated tools and online converters are designed for this purpose:

  • MIDI to WAV Converter: A lightweight program for direct conversion.
  • Online MIDI Converters: Websites that convert MIDI files to audio formats using built-in sound engines.

How It Works:

  • Upload your MIDI file.
  • Select your desired audio format.
  • Download the converted audio file.

4. Recording External MIDI Instruments

If you’re using a hardware MIDI instrument (e.g., a synthesizer or drum machine):

Step 1: Connect the Instrument

  • Use audio cables to connect your instrument’s output to your computer’s audio interface.

Step 2: Play the MIDI Sequence

  • Send the MIDI data from your DAW to the external instrument.
  • The instrument will generate sound based on the MIDI sequence.

Step 3: Record the Audio

  • Record the instrument’s audio output in your DAW or using an external recorder.
  • Save the recorded file as an audio format.

Tips for Better Results

  • Choose High-Quality Virtual Instruments: The quality of the final audio depends heavily on the instruments used. Use high-quality virtual instruments or sound libraries for the best results.
  • Optimize Your Mix: Before exporting, ensure that your mix is well-balanced. Adjust levels, add effects, and refine dynamics to achieve a professional sound.
  • Export in High Resolution: If possible, export your audio files in lossless formats (e.g., WAV or FLAC) for the highest quality. You can always convert these files to compressed formats like MP3 later if needed.

Conclusion

Converting MIDI sequences to audio files is an essential step in producing and sharing your music. Whether you’re working in a DAW, using standalone software, or recording hardware instruments, the process is straightforward and ensures your compositions sound their best on any platform. By following the steps outlined above, you’ll be able to turn your MIDI creations into polished audio tracks ready for release.

Sonic Producer – Create your own killer beats instantly

Along with providing a ton of MIDI Drum Files for people to download, I also like to search out and play around with new and different music software products.  Here’s one that I came across recently that I thought was pretty cool. It’s called “Sonic Producer” and it’s only about $30.

For those of you who like to make everything from scratch… Or those who like coming up with new musical style inspiration…  this one is for you. A powerful music/beat sequencer that has some amazing features. (and a very impressive price-point)

Basically, how it works is very simple.  As the software plays, you tap in the rhythms one track at a time. Then you can go back and add more and more instruments over the top of what you’ve already recorded making it as complex as you want. Very simple to use. And when you’re done you can export the finished product for use anywhere.

If you have every used the Re-Drum feature in Propellerhead’s Reason software… this is similar (except it doesn’t cost $500).

Watch the demo video …

Watch the Video above. Download it here.  Give it a shot.  Then come back here and let me know what you think about this attractive piece of music software. I would be very interested in your thoughts.

How to convert YouTube videos to MP3 audio

It has come to my attention that many people out there are looking for instructions on how to convert YouTube Videos easily into MP3 files for your MP3 player.  I know this isn’t directly related to the MIDI topic, but it is one step further in my quest to find the perfect YouTube to MIDI converter.

So I looked at a bunch of different options.  Only two stood out to me as being good enough to mention. If you have any other suggestions, please mention them in the comments below. I would be very interested to hear your thoughts.

The runner up (not my first choice) would be the web site: www.video2mp3.net .  The Good: It’s very easy to use. Just copy the URL link from the desired YouTube video and paste it into the form field on the Video2MP3 website, then hit “convert”. The Bad: There are some annoying Ad screens to wade through and the first time I tried it I got several pop-up spam screens (never good). The second attempt however, was pop-up free. They have two quality settings, normal and high. If you choose the high quality option you may need to stand in line. They have a Que system and it could take a while to get to you.  However, if you need an MP3 made from a YouTube video and won’t be doing this type of conversion very often, this is a solid option.

YouTube MP3 ConvertNext, and a better solution for me, is the FireFox plugin.  (found here) . The Good: You simply find the YouTube video you want to download as MP3 and click the “Download as MP3” button. Extremely easy.  THE BAD: It only works in FireFox, And you have to install 3 plugins before you can use it. The plugins are…

  1. Grease Monkey Plugin: Download Here
  2. Grease Fire Plugin: Download Here (optional but recommended)
  3. YouTube to MP3 Plugin: Download Here

However, if you have access to FireFox…  it is so easy. Plus, if you do use FireFox on any regular basis, you’re going to want the GreaseMonkey and GreaseFire plugins anyway. They are incredible enhancements to the overall browsing experience.

So, using the information I just gave you, within just a few minutes you too can have MP3 versions of your favorite YouTube clips.

Have another MP3 from YouTube conversion tip? Let us know in the comments below.

Converting MIDI files into Wav. Files (or .mp3, etc.)

MIDI Cables

Converting MIDI into any other audio format is not a “one click and you’re done” type of procedure. We discussed in the last email installment that MIDI is not audio data, it’s a language that allows musical instruments to talk with each other. That being the case, in order to get MIDI onto an audio CD or .MP3, you will need to record the midi data in ‘real time’. This can be done in a couple of different ways.

  • Get a MIDI to .wav converter program. One I would suggest to you is made by “MIDI converter”. This program works with many file types including .wav and .mp3 files. Click Here to download this great program: http://www.widisoft.com/
  • Assuming you want some control of how the end product sounds… you can record it manually. You will need to record the sounds you hear (created by the midi files) onto a recording device (probably your computer). These are the steps you will need to take to do that.
    • Once you select the midi file(s) you are wanting to record, select the sound source (This is what actually plays the MIDI file). In most cases this will be your computers sound card, however often a musician will want to use the sounds from a higher quality source, like a keyboard, drum machine, or external keyboard sound module. In the latter case, you will need to attach the external sound source to the computer via a MIDI connection. (depending on the model, you may be able to play the MIDI files from a floppy disk inserted directly into the unit, bypassing the need for a MIDI connection.)
    • Make sure that the midi file actually plays when you hit the play button.
    • Set up the sound source so that the music can be recorded as an audio signal.
      • In the case of an external sound source, simply connect the audio outputs to the “line in” of your computer.
      • If you are using a computer sound card, you will need to connect a short cable from the sound card’s “speaker output” to the sound card’s “line in” input. (Warning: if you don’t turn off the “line-in monitoring” in your sound card’s software settings, you will get massive feedback, so do that first.)

        There are some differences between “Line” and “Mic” inputs that you should keep in mind. The line level input functions in stereo whereas the mic input is usually only mono. The line input requires a louder, slightly ‘amplified’ signal (known as “pre-amp”). Weaker signals have trouble being picked up by a line input. The mic input however, is set to automatically amplify the incoming signal and therefore requires a weaker input signal that comes from a microphone. So don’t plug any line level signals into the mic input of your computer. In most cases, the audio signal coming from a ‘pre-amp’ sound source is too loud for the mic input to handle and you will get distortion (or worse… damage can be done). So be sure you hook it up right.

  • Press record on your computer’s software and then play the MIDI file.
  • Save the audio recording in whatever file format you want. You’re done.

As far as converting .Wav or .MP3 files into MIDI, there are solutions for this as well. You will need a “pitch analyzer”. There are many of these converter programs on the market. One I would suggest is the intelliscore converter program. That can be found here: http://www.intelliscore.net/

Some of these converter programs boast even being able to notate multiple pitches at the same time. For example, strumming a guitar and have the software recognize all six of the notes being played, or notating all the notes played on the radio. In the early days of Wav to MIDI detection this was nearly impossible and even getting one line to notate correctly was difficult. But with the advancement of technology comes better programming. Give it a shot and see for yourself.
