What Our Fantastic Users Say

"I often use the Melody Generator combined with a chords track, to spark ideas when I have complete writer's block. And sometimes I use the Idea Tool to come up with a random chord progression. I always come up with something cool and useful, even after experimenting for only 5 minutes."

Chris Caulder (Tentative Plans, Seldom Family)
Musician, Composer, Music Teacher 

"RapidComposer is the best tool in the world for making masterpiece music in less than 10 minutes. Finally, I have my one tool for writing REAL music."

"I have been a registered user of RapidComposer for years and I can honestly say that Attila never rests on constantly improving and adding refinements that truly make RapidComposer one of a kind. Please, keep up your hard work Mr Mezei it is much appreciated."

Robert Wiegert 
Producer, Composer

"RapidComposer is the most powerful compositional tool that I have used in over 20 years of producing music. I am able to create faster and more importantly to a higher level than ever before. It is function over form. Not pretty, but a huge amount of power lies under it's skin. If you are patient it offers huge reward. The price is very competitive and the Support from the developer, Attila is the best I have ever known. Anybody who makes music of any kind would be wise to give it a fair trial."

secondstep from KVRAudio Forum

"Rapid Composer is such a deep and inspiring tool that it is hard to put into words the joyful emotional affect it causes as you create music in a manner that is unlike any other program or DAW. It is very well designed and improved continuously by it's totally dedicated developer. There is some brilliance in this program! It has allowed me to develop music that I would not be able to otherwise with my limited knowledge of music theory. I totally recommend this program."

Philip Chance

"... But after I've spent some time with (another product) recently, I came to appreciate again what a fantastic tool RapidComposer really is. It's as deep and complex as the user wants it to be. If you need just a quick inspiration via a generator it does that effortlessly, as well as letting you dive deep into complex progressions and variations seamlessly.

I can't praise it enough. With V3 it also made some serious steps forward, in my humble opinion. So all i can say really is thanks for your hard and humble work. It's seriously appreciated. "

Gregor Gräfe

"RapidComposer is a remarkable composition tool for musicians. It's often classified as a sequencer, which is technically accurate, but it's so much more! To quote another user, "The potential of this program is VAST." There are many cool built-in features and tricks designed to help musicians, producers, and songwriters compose songs. [...] Thank you MusicDevelopments for developing this fantastic creative environment."

"RapidComposer is a fundamental rethink of every important aspect of computer composition. Structure and surface are wonderfully entangled in RapidComposer, casting a tool that puts ideas, form and texture at the forefront as never before."

"RapidComposer is extremely efficient in workflow, as a composer I can sense the intuition behind the well thought layout and when I felt something was missing I discussed about it and some of my suggested features were implimented in hours !
Impeccable service is the cherry on top of the amazing software

Israel Roy

"To me, RC is a tool that is always ready to help you create and combine backtracks harmonies and inspirational melodies very quickly.
Simply, import harmonies, phrases, rhythms from midi files to build libraries to your taste
and combine them to create your own as you wish!"
