  1. A ring-modulating instrument. This CLM instrument will apply ring modulation to a sound file with a specified sinewave. Ring modulation is a fancy name for multiplying the two signals together. When you multiply the two sounds together in the time domain, you get the sum and difference tones in the frequency domain.

    CLM Installation

    Contents CLM Installation Command Line Tools Load and Compile Instruments CLM Installation Common Lisp Music, by William Schottstaedt is a powerful sound synthesis language implemented in Lisp and C. CLM is essentially a toolbox for instrument building. Although it comes with a number of instruments ready to use, most composers use CLM to define their own instruments. For those of you that wish to dive into CLM sound synthesis system, I advise everyone to read this document carefully first. Command Line Tools First you need to find out if "command line tools" are installed in your system. The C compiler is essential at the instrument compile and load time. Launch the Terminal, found in /Applications/Utilities/ To check if command line tools are installed run: xcode-select --version if installed you will see the below with the version found in your system, something like that: xcode-select version 1234 If command line tools are not installed run: xcode-select --install A software update popup window will appear that asks: “The xcode-select command requires the command line developer tools. Would you like to install the tools now?” choose to confirm this by clicking “Install”, then agree to the Terms of Service when requested. Wait for the Command Line Tools package download to complete, it’ll be about 130MB and installs fairly quickly depending on your connection speed. The installer goes away on its own when complete. Enjoy your new unix command line toolkit! Load and Compile Instruments CLM system comes with a number of instruments which are a great starting point to see and hear CLM in action. Some of them are simple others are complex. Before you can run any of the instruments you must compile them first. To do that you need to open and evaluate a file “Load CLM Instrument.lisp”, you will find the file in the CLM directory. This process will take a minute or so and it will create binary and dynamic library files for each of the instruments. The binary files will be saved in the bin directory and the library files will be saved in the libclm directory. After this process is completed you are ready to run the CLM Examples. If you wish to load the instruments at the startup of the app move the "Load CLM Instrument.lisp" file into the “~/Opusmodus/Extensions/“ directory. Thats all you need to do to make CLM system work in Opusmodus. Next page fm-bell-synth

  17. I might add this function to the system, well done
  18. – New function: CHORD-PROGRESSION - sorts a sequence of chords and pitches to the lowest or highest chord note. – Update: AMBITUS function allows range smaller than 6 semitones. – Fixed: Quick Start - Lesson 1 - OMN – Documentation updates. CHORD-PROGRESSION This function will sort a sequence of chords and pitches to the lowest or highest chord note. Sorting to lowest chord note: (chord-progression '(g2g3 a2a4 a2a3 g2d4 g2g4 a2e4)) => (g2g3 g2d4 g2g4 a2a3 a2e4 a2a4) Sorting to highest chord note: (chord-progression '(g2g3 a2a4 a2a3 g2d4 g2g4 a2e4) :sort 'high) => (g2g3 a2a3 g2d4 a2e4 g2g4 a2a4) Examples: (setf omn '((q d4a4g5 fs4eb5bb5 eb4fs5d5 bb4g5a5 fs4eb5d6 bb4a5g6) (q g4d4a4 bb4fs4eb4 a4g5d6 eb5bb5fs6 bb4a5g5 eb5d5fs5))) (chord-progression omn) (chord-progression omn :sort 'high) (chord-progression omn :sort '(high low) :reverse '(nil t)) Best wishes, Janusz
  19. Here it is: (chord-progression '(g2g3 a2a4 a2a3 g2d4 g2g4 a2e4)) => (g2g3 g2d4 g2g4 a2a3 a2e4 a2a4) (chord-progression '(g2g3 a2a4 a2a3 g2d4 g2g4 a2e4) :sort 'high) => (g2g3 a2a3 g2d4 a2e4 g2g4 a2a4) The CHORD-PROGRESSION function will be part of the next release.
  20. What would be the result here: '(a2a3 a2a4 a2e4 c3f4 f4cs4 d4e4) Please make a few examples with the input and the output you are looking for.
  21. Do you mean number attributes? '(e c4 num0 cs4 num1 d4 num2 ds4 num3 e4 num4 f4 num5 fs4 num6 g4 num7 gs4 num8 a4 num9 as4 num10 b4 num11) You can extend the list of attributes with: ADD-TEXT-ATTRIBUTES function: (add-text-attributes '(v-ah "ah") '(v-ee "ee") '(v-eh "eh") '(v-ei "ei") '(v-ih "ih") '(v-mm "mm") '(v-oh "oh") '(v-oo "oo") ) The list of new functionality in version 1.3 is quite big, the workflow improved considerably as well not to mention the bug fixes.
  22. Short improvisation with three patterns, UNFOLD, PS, function Live Coding Instrument and VSL instruments: alto flute, clarinet, bass clarinet, viennese horn and cello.
  23. – Fixed: Removed AllNotesOff in Live Coding Instrument sequence-loop. – Documentation updates. Finally the Live Coding Instrument is working as it should, no more notes off while waiting. Best wishes, Janusz
