How to use these kinds of files in your keyboard and/or standalone midi sequencers.

What is a MIDI file?
MIDI is a means of communicating music information among synthesizers, keyboards, computers and other electronic sound equipment through digital messages. Unlike wave files, MIDI files do not contain any sound. Instead they contain commands that tell the receiving unit exactly what note to play, what sound it should be played with, how loud it is, and how long to hold the note on.

What this means is that when you get a MIDI file, you are getting a file that contains what the composer did on his keyboard. The file is fairly small because it contains no actual sounds or voice information. To play back this file you need either a keyboard with both a MIDI interface and a floppy drive or a computer with MIDI capable sound card.

Playing back a MIDI file.
Playing back a MIDI file is fairly simple to do. In most cases it is a matter of putting a disk that contains a MIDI file into the floppy drive of your keyboard, selecting the file to be played and playing it. Since MIDI is such a common standard, it truly is this easy.

Playing MIDI files is extremely simple, but getting the most out of the play back can take a little more work. Consider, for example, playing your MIDI file back on a PC with a standard sound card. You will quickly find that the sounds coming from your computer may be a little flat or lifeless compared when the same piece is played on a keyboard.

The reason for this is found in how sound cards work. Sound cards have a wave table IC that contains the sampled sound of many instruments. Due to the expense and work involved in sampling these sounds few standard sound cards contain sampled sounds that are even close to the quality found in most keyboards or sound modules.

A keyboard has been designed to reproduce high quality sounds. A sound card has been designed to produce sound, not necessarily “high quality”. So what can you do about this? The answer is simple, connect the MIDI output of your sound card, to the MIDI input on your keyboard, and set your computer to play the MIDI file out to the keyboard. Now when you play back the same musical piece, the keyboard will play it with its full sound compliment instead of using your low quality sound card sounds.

Also worth noting… there are available now, high quality sound cards with “synth” engines built into them. These cards are typically much more expensive than your average generic sound card though. Consult your local music store for more information about this.

How do I connect MIDI devices?
Connecting MIDI devices is a fairly simple task. The standard cable for MIDI is a 5-pin cable with a small round connector. This cable carries the digital commands from one unit to another.

To connect the MIDI devices start with the master unit. All MIDI units will have jacks labeled as IN, OUT and most have a THROUGH. Take a suitably sized MIDI cable and go from the OUT of the main unit to the IN on the slave unit. Then take a second MIDI cable and go from the IN of the first unit to the OUT on the slave unit. (Note: the Out from one unit cannot connect to the OUT of the other. This will not work. An OUT must always connect to an IN).

Now that the digital command links have been established you can begin to establish the audio connections. Start with the slave device and run a patch cable from the audio out to the audio input on your mixer or amp.

These simple connections are all that are required. Now you can use the main unit to cause any of the other unit(s) to play music as you see fit. Remember the shorter the cable run the better the signal quality will be. And it is not recommend to run more than 4 or 5 units in a MIDI chain as the signal can become weak and unstable.

Further details.
The exact details for playing back MIDI files on your keyboard, sequencer or drum machine will vary with different models. While the basic steps are usually the same, the best source of instruction is yours owners manual.

If your instrument has a disk drive, normally you would start by saving a MIDI file on a standard DOS formatted disk. After the file is saved, you insert the disk into the floppy drive on your digital instrument. Use the built in floppy drive controls to select the MIDI file on the disk and then select play.

Playing back a MIDI file on your PC may be slightly more complicated but still is very simple. The first step is to ensure that the MIDI drivers for your sound card or MIDI ports are installed and enabled. The information that came with your sound card will tell you how to this properly.

On a PC it is very common to use some sort of music editing software to play back or modify a MIDI file. Follow the manufacturer’s directions to install your music editing software and ensure that it works with your sound card.

Once the software and hardware are ready you can begin having fun. Insert the disk with the MIDI file into your PC’s floppy drive and open the file with your music editing software. The software will allow you to play or change the file as needed.

As you can see, thanks to industry standards, using MIDI files is fairly simple to do. You will be amazed with the possibilities that are opened up once you begin working with MIDI files.

Cool ways to use these MIDI drums for fun.

Music Fun
Music Fun

Forget work, huge recording studios, expensive gear, towering effects racks, and sequencing learning curves. Let’s talk about how to use these MIDI Drum Files just for fun.

Out of the 10,000 or so people that have accessed our drum files recently, a large percentage of them use the files to back up original music tracks. Another block of people download them specifically as cell phone ringtones (more about how to do that in a later email). But hidden in there somewhere is a group of people that come up with creative uses for these files just for fun. I thought you might like to hear some of the stories and get some creative ideas for yourself.

Take Mary (San Francisco, Ca), for example. After getting our complete set of MIDI Drum Files, she selected about 35 and proceeded to chain them all together using Cakewalk’s Sonar 3. She added some strings over the top of the beats and converted them into one long MP3. Now they can be heard almost every day in the lobby of her ‘modern dance’ studio in Southern San Francisco. Thanks Mary.

Then there’s Toby (Springfield Mo.)… Junior High camp director. He bought these files for a 2003 summer camp he was involved with in Missouri. Selecting out the Rap and Rave, beats he gave the students one week to come up with the best rap about their counselors. The kids were able to pick the beat they wanted and could perform it in front of everybody. The show was a screaming success and the performers had their friends rolling on the floor with laughter. Thanks Toby.

OK, its Halloween night, the lights are dark, the spider webs are hung above the entry way. Who better to greet unsuspecting trick-or-treeters than Snoop Doggy Dog Himself…. Or at least Mark H. of Houston TX. made up to look like ‘The Dog’. The drum files play all around his house to make it sound like one of his rap song drum beats. He greets the kids who stop by. Most of them ask if he really is Snoop. Thanks for the creativity Mark.

These are some stories that have come from creative people over the years who not only get good use out of our MIDI Drum Files, but also have fun with them in the process. If you have any stories like these of creative ways to use our drum files… Please let us know about it.

MIDI Ringtones for Cell Phones

MIDI Ring Tones
MIDI Ring Tones

Are you tired of having the same ring on your phone as everyone else? Would you like a specific riff as a ring tone but can not find it or do not wish to pay high user fees to get it? Well the good news is now you can with the aid of your MIDI instruments.

Custom ring tones have been popular ever since cells phones allowed users to change the ring. A new industry has sprung up to meet the demand for custom ring tones. As part of this industry a new type of MIDI file has been introduced called SP-MIDI.

MIDI began as a way for electronic instruments to interact with each other, and any computer can play MIDI files. Recently a group of interested parties came together, including Beatnik, Nokia and the MIDI Manufacturers Association, to create an adaptation of MIDI to work in handheld devices such as cell phones and PDAs. SP-MIDI provides the flexibility to both the user and the mobile terminal manufacturer to address differing customer needs.

Generally speaking, these new phones come with 8 notes but higher priced models have up to 32 notes. As you would expect with MIDI, the same SP-MIDI file can be played on any phone that supports it regardless of the make or the number of tones available. This is a huge advantage for people who switch phones periodically as now they only have to get their custom tones once. From there they can transfer the files to their new device.

Here are steps in the process of making a MIDI file SP-MIDI compliant.

1. Create the MIDI file.

As I am sure you have surmised, the first step is to either select a MIDI file on your PC or to record a MIDI file on your PC.

There are many software packages available, some for free. Nokia Audio Suite allows you to use MIDI sequencer programs such as Cakewalk to create SP-MIDI files.

Anvil Studio is an excellent choice for general MIDI work if you do not already have software. Anvil Studio offers plug-ins that makes the creation of SP-MIDI files fast and easy.

2. Streamline the file.

Now comes the musical and picky part. After recording a piece or opening a MIDI file you need to ensure that there are no more than 4 voices and limit the sound volume. You will wish to limit the number of voices to 4 as that is the default setting for portable devices and limit the maximum volume of the piece so that it can be played even with a low battery or if there is high processor usage.

Limiting the number of voices means reducing the number of voices present. With pre-made MIDI files this can be a little difficult. Some MIDI files download from the web can contain as many as 23 voices, so it is a matter of deciding what voices are not important to the integrity of the piece. For example you may be able to eliminate the soft flute voice in the background of the piece.

With the MIDI file complete it is time to audition the MIDI file with limited voices. For this Beatnik is an excellent software package that can be tried for 14 days for free.

Nokia licenses beatnik so you will be able to hear the piece exactly as it will sound on your phone. While playing back the piece ensure there aren’t any extra voices, swells in volume and that it sounds good.

3. Convert the file to SP-MIDI

Now things get a little tricky, as we need to generate MIP data to make the MIDI file SP-MIDI compatible. MIP data insures that the device will know which tracks are the most important. According to the Beatnik SP-MIDI Best Practices Guide “Each channel used in a SP-MIDI file requires a MIP value.”

The MIP values, which are entered in hexadecimal and added to the start of the file, can be figured out manually according to the standards, but it is best if your software does this automatically. The process used to determine the values for the MIP table can be found in the links provided below.

Once you or your software package have added the MIP data to the MIDI file all that remains is to convert it to SP-MIDI by saving the file as SMF format 0. Depending upon the software you are using this can be done by selecting ‘save as’ from the file menu or changing the options for format. Exact details can be found in the instructions that came with the software.

4. Upload the file

Now that you have created your custom ring tones it is simply a matter of loading them into your phone. Each phone is a little different so you will have to refer to the manual that came with your phone for exact instructions. With some phones the rings can be loaded directly from your PC into the phone. For other phones you will need to use WAP. With WAP you dial a certain phone number to connect to the service provides or manufacturers network and select the file to load. Often you must pay for this service but there are a number of free options.

With all that work done you now have your own custom ring tones that you can change any time you like. Have a little fun and create your own theme music that changes depending upon your mood if you like. The possibilities are limitless.
