In the last article, I had shared my views on why programmers should learn Prolog, preferably as the first language. What language should one learn next? I strongly pitch for Lisp, to be precise, “Common Lisp”. Lisp happens to be the second oldest (1958) programming language, only after Fortran (1957)! Initially there were several dialects […]
L-system is a powerful string rewriting system. Opusmodus supports an implementation of this system (inspired by and based on this implementation). It is possible to use the L-system to generate anything that can be described in terms of an alphabet and a set of rewriting rules. Let us start with a simple example: As you can see, there are […]
The recently concluded Black Friday sale by UVI was an irresistible temptation for me and I ended up investing in Falcon 2 and a few other instruments. Although I have the latest versions of Ableton Live, Propellerheads Reason, Renoise, and Reaper, I felt Falcon 2 would be a good addition to my existing collection, mainly because […]
I have recently started implementing a library for algorithmic music composition. It provides higher-level algorithms and abstractions for composing multi-track music, and works with Opusmodus software. Opusmodus is a great platform for music composition and has excellent support for MIDI-based music. My library is an attempt to enrich the Opusmodus platform with features that facilitate easier […]
In mathematics, the simplest example of Random Walk is a random process along a one-dimensional plane of integers, starting at 0 and moving in the positive or negative direction in steps of +1 or -1, with equal probability. The Random Walk theory has been applied in many domains including Physics and even the Stock Market. Here is a […]
I am a great fan of Opusmodus software. I have written many articles about it in the past. Owing to my several other commitments, I am not able to spend much time on it these days, but I keep checking the features in new releases regularly. The software has evolved substantially since its first release a […]
In the previous two posts on this topic, I explained some of the basic pattern matching facilities of Optima library. There are many more advanced features in the library and I will try to discuss them in future posts. In today’s post, I will outline a straightforward application of the library for processing scores in Opusmodus. In […]
Sometimes it can be interesting to take a MIDI file and transform the score it represents. For example, you can change the tempo, alter the instruments, or even modify the pitches and rhythm. To do something like this, it is helpful to build a convenient framework. In today’s post, I am outlining one approach that […]
One of the creative approaches to synthesizing music is to start with a short melodic motif and then apply various transformations on it. The motif is usually (but not necessarily) of 1 bar duration. What are some possible transformations? This depends on one’s creativity, but here is a simple list: 1) Identity transformation: Do nothing […]
In my last post, I explained how we can use Cellular Automata (CA) in Opusmodus to create music. For today’s post, I wanted to build a simple UI to control the parameters used in the CA example. This posed a practical difficulty. Opusmodus does not yet provide a GUI library. Even Clozure CL, on which Opusmodus […]
