Just a reminder about the new functions I added in the last few updates: respell find-chord find-root find-scale chromatic-scale filter-chromaticBest wishes, Janusz

Improved the RESPELL function and fixed the Opusmodus GPT display issue on macOS. RESPELL The RESPELL function is used to change the pitch names of chords to prevent the occurrence of identical note names and to avoid enharmonic duplication that could lead to notation display conflicts. This is especially useful in complex harmonic textures or clustered chord voicings, where multiple notes may share the same pitch class but require distinct enharmonic spellings for clarity. By adjusting the spelling of pitches (e.g., converting a cs4 to db4), the function ensures more readable and accurate notation.

After receiving some feedback on the new function, I decided to expand its functionality further. I hope it will become a useful tool in various contexts of your composition. Update 3.0.29556 split-chord (chord-span sequence &key lower-size upper-size lower-ambitus upper-ambitus lower-transposition upper-transposition lower-closest-path upper-closest-path rotation index) chord-span - Either a single integer or a list of integers specifying the maximum span (in semitones) for chord splitting:mSingle integer: Applies the same span to all chord-splitting events. List of integers: The function loops ove…

Opusmodus GPT has been integrated into the Assistant on Windows.

ChatGPT (Opusmodus GPT) can be opened directly in the Assistant window. This new functionality is available only on Mac, as LispWorks does not support browser plugins on Windows. For now, the "Opusmodus GPT" menu will open in the browser on Windows. Best wishes, Janusz

Added 24-bit support for the AIFF file format to the SPECTRAL-ANALYSIS function.

Opusmodus 3.0.29517 With the new SPECTRAL-ANALYSIS function, you can analyze audio files directly in Opusmodus. The SPEAR application is no longer required to generate spectral data. SPECTRAL-ANALYSIS spectral-analysis filename &key start end fft-size window-size hop-size frame-interval min-peak-diff min-amp-db under-peak-db window min-freq max-freq normalize sample-rate Arguments and Values: filename String.

Julio Herrlein Study and Practice in Composition with Opusmodus This is the second volume in the series of publications specifically dedicated to composing and analyzing music using the Opusmodus system. The primary purpose of this book is to provide a narrative of the compositional process in Opusmodus and demonstrate the interplay of functions in a typical daily workflow of practicing and studying composition. Simply having all the information scattered throughout the documentation is not enough to show how a composer connects ideas in the compositional process. Not everything in the composition can be reconstructed, due to the rapid flow of d…

New function: DIATONIC-CHORD The DIATONIC-CHORD function generates chord sequences based on diatonic chord symbols relative to a specified key. It allows for flexible chord progression creation in both major and minor keys by interpreting chord degrees (e.g., I, ii, V7) within the context of the given key signature. The function supports key signature specification, inversions, and drop voicings, enabling composers and music theorists to programmatically generate chords with varied harmonic textures and smoother voice leading. This function is ideal for composers and arrangers who wish to streamline the creation of chord progressions, allowing for …

Opusmodus version 3.0 is fully compatible with macOS 15 (Sequoia). Best wishes, Janusz

3.0.29376 – Fixed: When performing UNDO or REDO, the system wasn’t correctly computing the required colours. In revision 29376, we made adjustments to always trigger a re-colouring process after each UNDO or REDO. This should resolve the issue with incorrect colouring after an UNDO operation.

3.0.29389 In my latest update, I inadvertently introduced a bug into the QUANTIZE function. Please update to the current version. Best wishes, Janusz

3.0.29374 – Additions: The 'Display Commands List...' will display in all windows. Note that the commands can be in principle different between buffers, and the list is for a specific buffer. When the interface doesn't have an editor buffer, The 'Display Commands List..' finds the top workspace window and use it instead.

3.0.29368 When the search string matches a function, it goes to it immediately. The search history in Composer editor is independent for the Navigator search history. Best wishes, Janusz

Additions and improvement to DECHORD function: Extracts the root pitch from each chord by default: (dechord '(q c4 f4a4d5 e fs5)) => (q c4 mf f4 e fs5) Extracts the root pitch but returns it in normal-order (Pitch Class Set): (dechord '(q c4 f4a4d5 e fs5) :type 'pcs) => (q c4 mf d5 e fs5) Selects the 2nd pitch from each chord: (dechord '(q c4 f4a4d5 e fs5) :pitch 2) => (q c4 mf a4 e fs5) Selects the 2nd pitch and returns it in normal-order: (dechord '(q c4 f4a4d5 e fs5) :pitch 2 :type 'pcs) => (q c4 mf f4 e fs5) Applies the default pitch selection to a sequence of chords: …

Opusmodus has added Dark Mode support for Windows. Both systems allow customisation of Light and Dark modes separately. Best wishes, Janusz

COUNTERPOINT additional functionality: orchestra (Optional): Lists all instruments involved in the composition. This comprehensive list ensures that the counterpoint function can consider the full ensemble when applying transformations and generating output. instruments (Optional): Identifies a subset of instruments from the orchestra to which the counterpoint operations are specifically applied. This allows for targeted manipulation of particular voices or sections within the ensemble. Orchestra and Instruments The :orchestra and :instruments options are employed within the COUNTERPOINT function for orchestrating ensemble or orchestral compositions. These options e…

Additional DICTUM types: :grace-note and :previous Executes a specified function applied exclusively to grace note events. (:do (pitch-transpose 12 x) :grace-note t) Executes a specified function within the specified bar(s) exclusively to grace note events. (:do (pitch-transpose 12 x) :grace-note t :bar 2) This operation alters elements meeting certain predefined conditions from the preceding event, replacing them in the current event with a new element. Such conditional manipulation facilitates intricate, criteria-driven modifications. (:previous ff :do p) (:previous (h c4 f) :do (pp tr)) Example: …

To all users of the DICTUM function, please be advised that there have been changes to the DICTYM types. It is essential that you update these types within your scores if you are utilizing this function. This adjustment is necessary to ensure compatibility and functionality within your projects.

To streamline the process of importing SPEAR spectral data into the Opusmodus Library, the three-step procedure has been consolidated into a singular operation. Consequently, the IMPORT-SPECTRAL-SPEAR function has been deprecated and superseded by the newly introduced SPEAR-DATA-TO-LIBRARY function. This enhancement simplifies the importation of SPEAR data in the form of .txt files into Opusmodus, making it more straightforward. ----- SPEAR-DATA-TO-LIBRARY &key data name section index note This function processes and imports spectral data from the SPEAR (Sinusoidal Partial Editing Analysis and Resynthesis) application, developed by Michael Klingbe…

Very fun experience with OM spectral function! Have you ever heard a piano speaking?

Great video form Stephane Boussuge.
