More Information


PROSONIC'S new MIDI PROGRESSION SERIES went GOLD on May 1st 2007 and it's going to blow our creative possibilities wide OPEN!

This isn't like one of those old "chord dictionaries" in a paper book... It's a full-blown MIDI library that's over-flowing with thousands of professional, four-bar chord progressions in multiple time signatures!

You'd have to purchase hundreds of "chord dictionary" books to even come close to the content on this CD, and since they're all in MIDI, you can hear the progression instantly with any MIDI instrument you have. No paper book could ever do that!

This CD is like having a WHOLE LIBRARY of "chord dictionaries" and you can use the chord progressions in your own music royalty-free!

Each progression is carefully crafted to follow correct harmony & voice leading rules and the result is amazing! Every inversion is included and each chord is notated with MIDI marker events so that you know exactly what harmony is voiced at each spot in the sequence! (see images below)

I've experienced instant inspiration and song writing has never been easier. Each MIDI progression is like a creative launch-pad for your melodic ideas and the 'next part' in the song just leaps out at you! Begging you to take it to the next section!

If you perform an instrument these progressions are an invaluable tool for perfecting your improvisation skills. I play guitar and these have instantly made me a better player.

Just randomly select a progression and loop it over one of the PROSONIC MIDI DRUM BEATS! If you get stuck on a chord and can't seem to find the right notes... just look at the MIDI marker and you'll know exactly what chord it is!

I've found the progressions incredibly useful for honing my bass and vocal phrasing too. I can put up a progression and score a bass line to it. It's really amazing what happens when you have a simple harmonic structure to work from. This is going to revolutionize our craft and I'm extremely pleased to share it with you.

"Triads in Simple Rhythm & Common Time Signatures" is the first library in the MIDI PROGRESSION SERIES. These progressions can be used in any style and are perfect for a base layer to build your song up from!

There are over 160,000 four-bar diatonic and non-diatonic progressions in this library [and they all sound as good as (or better than) the demos] so be ready to stretch your sonic imagination beyond the limits!

Midi File Organization / Folder Structure

1. ROOT:

The first folder is the ROOT folder. It contains all of the MIDI Chord Progressions. It is named Midi-Progression-Library and is selected (highlighted blue).

root midi chord folder


Inside the ROOT folder are the TIME SIGNATURE folders. In the Simple Rhythms & Common Time Signatures Library there is 2/4, 3/4, 4/4, 6/8, 9/8, and 12/8 and in the Simple Rhythms & Complex Time Signatures Library there is 5/4, 6/4, 7/4, 5/8, and 7/8. We currently have the 4/4 folder selected.

time signature folder


Each TIME SIGNATURE folder contains the TONIC QUALITY folders. In this case Major and Minor. Chord progressions in Major Key are found in the Major folder and progressions in Minor Key are found in the Minor folder. We currently have the Major folder selected.

tonic quality folder


Inside the TONIC QUALITY folders are the CHORD TYPE folders. We currently have the Triads folder selected.

chord type folder


Inside the CHORD TYPE folders are the PROGRESSION START folders. These folders contain chord progressions that start on each scale degree in the key. We currently have the "Start at I" (tonic in major) folder selected.

chord progression start folder


Inside the PROGRESSION START folders are the CHORD STOP COUNT folders. In this case we have "4 Chords" and "8 Chords". In the "4 Chords" folder there are progressions that have four chord "stops" or "pulses" and the same for "8 Chords". (Except there are eight chord stops in each progression.)

chord stop count folder


Inside the CHORD STOP COUNT folders are the PHRASE TYPE folders. The "Phrase Type" indicates how the second two measures are treated in the progression. In "NoRepeat" the second two measures are different than the first two. In "QuestionAnswer" the first two measures are the "question" and the second two measures are the "answer". In "Repeat" the second two measures are a repeat of the first two but played a little differently. We currently have the NoRepeat folder selected.

midi chords phrase type folder


Inside the PHRASE TYPE folders are the actual PROGRESSION folders. Each folder is named according to what progression it contains. The image below was taken in the "8 Chord" folder so that you can see it too. Notice that there are eight chord stops in each progression.

midi chord progression folder


Finally we are at the actual MIDI files. (Examine the file name in the above image.) The file name contains more information about the progression. At the beginning of the file (up to the '_') is the Rhythmic Pulse. So, for example, the first file (starting with "Beat1And2") has chords that sound on the 1st and 2nd beats of the measure.

The second part of the file name (the part after the '_') is the Beat Grouping. [This is only included in complex time signatures like 7/8.] Each digit represents the eighth note count in each beat. So, in the first file shown above, the Beat Grouping is 223. So there are 2 eighth notes in the first beat, 2 eighth notes in the second beat, and 3 eighth notes in the third beat.

The third part of the file name (the part after the second '_') is the Chord Inversion indication. 0 = Root position, 1 = First inversion, and 2 = Second inversion. Each position applies to each chord sequentially.


Inside each MIDI progression file are the MIDI CHORD MARKERS. Each chord stop and its chord symbol are provided. So, looking at the image below, each chord has its chord symbol (and its inversion) marked above it. So the first chord is the tonic major in second inversion, and the second chord is a minor second chord in first inversion, etc.

MIDI Chord Progressions FAQ

Is the download version different than the shipped vesrion?

No, they are exactly the same. The download version contains exactly the same files as the DVD except you can start using them now!

What is a MIDI File?

The word "MIDI" is used to describe a few different things. A "MIDI file" can be thought of as "Sheet Music in Digital". (Sheet music that computers can read and play.)

Why use Prosonic Patterns instead of audio loops?

MIDI is a superior method of music composition for a number of reasons.

If you've ever used audio loops to write music you know how frustrating it can be to get them to fit just right in your song. You might find a great drum loop but how can you develop it while keeping the same drum sounds? You can only make variations on the timbre of the sound itself and that's it.

With Prosonic Patterns you have total control over every aspect of each note. Need to bring the hi-hats up in the mix? Easy! Need to change that note and make it sweeter? Just move it where you want it! Don't like a note... delete it!

You can also use a Prosonic Pattern for any instrument. So you can use a drum loop on any instrument (flute or violin for example) and come up with very unique and creative musical ideas!

You can even change the tempo of a Prosonic Pattern and the sound of the drums will be exactly as you sampled it.


We use the term "MIDI CHORD PROGRESSION" to mean: a 4, 8, or 16-bar musical chord progression (in MIDI) that is crafted to follow correct harmonic and voice leading rules.

What software can I use Prosonic Patterns in?

Every Prosonic Pattern is compatible with, and can be loaded into, any MIDI compatible software or hardware device (ie: your favorite sequencer).

Loading them into Propellerhead's Reason™ and Twelve Tone's Sonar™ has been especially rewarding. They are perfect for Cakewalk Project5, Battery 3, Cubase, Garageband, Pro Tools, Motif ES, Fruity Loops, EZdrummer, DFH, Sony's ACID® Pro, Ableton Live, and many more!

This is a fantastic product. I use these patterns frequently in Sonar to create tracks for synths. So easy to use, just drag the midi on to your midi track and you're ready to go!

They truly inspire ideas for compositions and songs. These are also great for jamming to. I have had many flashes of inspiration just listening to the progressions in Sonar. Its so easy to lay out a progression and hook up a synth for jamming.

Definitely glad I found Prosonic!

I used ProSonic's triads and chord progressions to help me in my compositions of electronic music. They were so much fun to put into my soft synths and get my creative juices going. These libraries were some of my "go-tos" when I got into a creative funk. I was amazed by the depth and breadth of the libraries. I would highly recommend them to anyone who is interested in coming up with some unique ideas or who would like to explore some new or interesting melodic or rhythmic ideas. -Keats Handwriting

So far, I've purchased two libraries from Prosonic, one of chords progressions and one arpeggio package, and I'm amazed at both the quality and quantity of the patterns here.

Whether you're looking for some ideas for chord progressions or want to build an entire song from scratch, these libraries have you covered.

The price is also pretty nice, considering that it would only buy you a fraction of this number of patterns on many similar sites. I've hardly scratched the surface of my first two but I can't wait to get my next library!

A massive quantity and variety of clips

These progressions were assembled with both talent and mathematical precision. Laid out in logical sequences, it's a snap to find what you are looking for. They are arranged in small enough chunks to fit easily into my Yamaha's annoyingly arcane file system.

With such a massive quantity and variety of clips you should always be able to find sounds with precisely the mood and nuance you seek.

As a teaching tool they are invaluable. You can hear the subtle effects that small (or large) changes have on perception and use these in subsequent efforts.

This is one of those rare times when a product that I didn't even know existed has instantly gained a prominent position in my musical toolbox. Thanks Prosonic!

I have really enjoyed the midi libraries I have purchased from prosonic studio. The MIDI files are very natural sounding and also greatly arranged. It is easy to navigate through the files to find what you're looking for because everything is labeled by the cord and/or note. I have purchased a lot of midi libraries and content online and often felt like I did not get my money's worth because the MIDI files we're basic and didn't sound very natural and we're not things that I didn't feel like I could have done on my own as to where prosonicstudio on the other hand gives you an edge moving into your production!

A fantastic value for the money! Well organized and complete, my library was super easy to install. After browsing just a few progressions, I was hit with the inspiration bug and started working on a new song right away!

I find the library is easy to navigate, making it very simple to find just the right progression for the song I am writing. Once I find the pattern I need, I love being able to just quickly drag the file right into my Logic Pro X. This has considerably sped up my workflow!

I find these patterns extremely invaluable. I have been poking around Loop Pack sites and subscription services for the ideal midi patterns for ages and always had to shell out lots of money just to get some that 'will do for now'.

Tony has taken on a gargantuan task, a labor of love coming up with sequences that work very well together and that will fit in admirably with anyone's music producing needs.

They also help a lot when you have music writer's block. It's a great starting point to what could be your next masterpiece or hit. Well done Tony!

Prosonics libraries are very very good value for the money, First of all, they are arranged/organized sensibly so finding what you want is a breeze. They are very broad in scope and cover a lot of ground so it's very likely you will get what you are after. Simply find a style, select a key, then choose from the many variants available. I get particularly happy results using the chord progressions for feeding any arpeggiator. They work great for me especially since my keyboard and music theory skills are not strong. Hands down, a good buy. Do not miss this addition to your music tool box.

I have been using Prosonic midi libaries for a couple of years and find them invaluable. I will often start with one of the Prosonic templates as a base and build a song from there. I have used in Ableton, Pro Tools and Native Instruments Maschine Studio.

I will also say the drum patterns were extremely useful as a learning tool when first getting my head around creating realistic drums for my computer based music. I had never played the drums before and other midi patterns I picked up elsewhere were very basic and did not provide much variety.

They provide the "get me started" building blocks

I do not consider myself an especially creative person. But with the Prosonic libraries I can still make music!

They provide the "get me started" building blocks that I use with my Digital Audio Workstation midi software to expand into full pieces. Transpose, copy 'n' paste, edit here and there, assign instruments to the tracks, and there I am - a complete work! With assurance that "the notes go together", which is an important benefit for someone like me who has only limited music theory. Don't let that hold you back!

I especially like the drum beats, though. And the syncopation options Prosonic provides give me plenty of opportunity to "mix it up" and avoid falling into a simple, boring 4-4 beat.

Thank you Prosonic Studios!

As a singer, songwriter, and producer who has lots of great ideas, but NOT the greatest foundation in music theory, I have found these libraries to be INVALUABLE in my production. If I have an idea I am toying with, I can always count on these libraries to have a progression that fits.

1. I needed some MIDI files for music production in my DAWs (Ableton Live, FL Studio and Studio One), and

2. I wanted to learn how to play some of these progressions on keyboards as I am a trained percussionist and not a keyboard player.

What I did not expect was the huge number of MIDI files in the pack, I have not even listened to 10% of them!

I will go back to this library over and over again for inspiration and practice.

I just love this collection!

They're an infinite pallette of musical capability...

Prosonic libraries are the most detailed, musical, and comprehensive midi packages in the world.

You cannot find midi samples of this kind of quality and in such large quantity per package anywhere.

Since buying prosonic I have never needed another midi pack and have enough material to feed my vsts for life.

Can't thank you enough Tony, you have eliminated all writers block and given me an infinite pallette of musical capability for years to come.

Helping me find ideas for new compositions

I was having real problems creating new music. In a real slump. I discovered the chord progression packs and bought a few.

At first I was completely overwhelmed by the sheer size of the collections. I called Prosonic and Tony answered. He was incredibly supportive and helped me get a handle on how to navigate the collections and, more importantly, how to use them.

The progressions are really helping me find ideas for new compositions.

I'm out of my slump and enjoying the creative process again.

For me it's like a secret weapon...

I often use the "4-Voice MIDI Chord Progressions" as an Inspiration or as a starting point. It is also useful for me to practice Improvisation.

I'm really impressed about the large amount of Chord Progressions. It's great to use them with Instruments which can play Arpeggios from Chords.

I also like the "Major & Minor Arpeggios" which I often use in my Vienna Instruments Pro Midi Sequencer (you can import Midi-Files...).

I also like that all future versions are free for Life.

It took some time to find something like this. I dont't use it every time, but for me it's like a secret weapon.

Its a good package and all at a decent price

With a little effort you can build some good progressions. I usually use the midi within EZ Keys then send the signal to other virtual instruments, lounge lizard, classic organs, pianos etc...

You can even use the midi progressions to send to orchestral vst instruments. All depends on how creative you are using the midi.

All the chord progressions are organized very well, so its easy to lay something down quick. All in all i think its a good package and all at a decent price.

"I use these chord progressions every time I practice. I even used a few on my new album Intergalactic Highway."
