Hi, For those who are interested, my sequencer plug-in for Audacity seq2test.ny is now ready for public testing - if you wish to test it, seq2test.ny is available from www.shellworld.net/~davidsky/seq2test.zip which contains seq2test.ny and seq2test.txt [help file]. Appears as "Audio Selection Sequencer 2 for public testing" under the effects menu. Brief description follows. If you have anyh problem using the sequencer, or think the instructions need some clarification, please let me know. After feedback and adjustments where needed, I will release seq2test.ny as seq2.ny. Thanks David * seq2.ny: Audio Selection Sequencer 2 Much improved over the sequencer I wrote in December 2004. Load or create a brief piece of audio into Audacity (a guitar pluck or bell sound, cat meow, someone saying "hello", any sound); select this audio, open Audio Selection Sequencer 2 in the effects menu, set different values such as tempo, beats per sequence, and semitone values of sequence, and seq2.ny will turn your audio selection into a (repeated) sequence of notes based on what you programmed. Comes with an 8-note default sequence already programmed in. Features: - you can set the volume for each generated note; - you can set the pan position for each generated note if it's stereo; - you can generate a series of transposed sequences; - you can have the sequencer randomize the order of the notes you programmed; - you can have the sequencer randomize the timing of generated notes; - up to 96 sequential notes (including rests) for a single sequence; - you can set when the sequence should start [starting offset]; - and more. -- David R.

Hello, at least two problems: 1. Instruments change register--below my drip generator has a low pass filter and there is a change of timbre for each note. You may have already considered reading the generating function for each note, or have filter options for an arbitrary sound. Converting each note to "full blast" default does not make sense. 2. Beware of Equal Temperment! Harmony books say that the third of a major chord should not be doubled. At the mid-range, playing it softly causes the frequency to drop by about a hertz; and toward the direction of Ptolemy tuning = 5/4 ratio. This does not happen if sounds are generated by the computer. This type of program has market potential but; as is, will not make a nickel. All the computer-generated music schemes have failed, the latest being Zel. Mathematical music is a rather different topic. The semitone distance from C is fine, for now. Nearly everything else is a distraction. To be of immediate use there should be a check or radio buttom for various tunings. -Pythagorrean Pitch: C C# D Eb E F F# G G# A A# B C Ratios: 1/1 2187/2048 9/8 32/27 81/64 4/3 729/512 3/2 128/81 27/16 16/9 243/128 2/1 Cents: 0 113.7 203.9 294.1 407.8 498 611.7 702 792.2 905.9 996.1 1109.8 1200 -Ptolomy -Werckmeister (J.S. Bach) -etc. These tunings can, of course, be used with random notes; but that is not why a person studies music for 20 years. I encourage you to create a version for real people. Will be delighted to send specifications, test, and create short MP3's.

Hi Paul, Paul: 1. Instruments change register--below my drip generator has a low pass filter and there is a change of timbre for each note. David: Thanks for posting your drip generator, I enjoy some of the "glassy" sounds it makes! Yes instruments change their timbre with pitch change. And I considered including code to change the timbre of each note depending on its pitch. At the moment I've chosen not to, for reasons I won't go into here. Paul: Converting each note to "full blast" default does not make sense. David: since the sequence gets normalized to 0.95, that's irrelevant. Plus the default amplitude is 1.0 only if the user leaves out the volume value for that particular note. Also, as stated in the help file, the user can enter numbers beyond 1.0 - again, the sequence gets normalized. Paul: 2. Beware of Equal Temperment! Harmony books say that the third of a major chord should not be doubled. At the mid-range, playing it softly causes the frequency to drop by about a hertz; and toward the direction of Ptolemy tuning = 5/4 ratio. This does not happen if sounds are generated by the computer. David: If you examine the code, you'll see that Nyquist (the computer) calculates the pitch change for each note, depending on what the user entered into the plug-in. I wrote the sequencer for my own enjoyment and that of the general public Audacity users. If you wish to modify it to your tastes, I'd be delighted to hear what you do with it! Paul: This type of program has market potential but; as is, will not make a nickel. David: Like Audacity, it's open source software, I don't expect to make money from it. My payback is learning, and enjoyment! Paul: All the computer-generated music schemes have failed, the latest being Zel. David: Then why are you on this list? Many Nyquist users use it to generate music. Paul: Mathematical music is a rather different topic. ... These tunings can, of course, be used with random notes; but that is not why a person studies music for 20 years. David: That's your choice. Paul: I encourage you to create a version for real people. David: Yes, I'm quite false, and intend to stay this way. David -- David R. Sky http://www.shellworld.net/~davidsky/ |
