[edit] Livecoding Narratives (Non-Fiction)

(things that I really did, reconstructed from memory)

[edit] "endless interesting claim generator"

• launched impromptu
• opened included speech example
• noted calls used to make speech play
• created a new text buffer
• added expression to speak the string "cats" immediately
• ran that expression a few times
• defined a loop duration (1 sec)
• created temporally recursive function using duration (loop)
• started recursion (stays running unless otherwise specified)

• modified loop to use "cats"-speaking expression
• changed "cats" to a random selection of "cats" "hats" and some other words
• defined two empty lists: subjects, modifiers
• added a few silly plural nouns to subjects list
• added a few silly prefixes to the modifers list
• modified speaking expression to concatenate a random element of modifiers, a hypen, and a random element of subjects
• extended loop duration a bit
• heard "mega-cats", "ultra-packets", "super-hackers" and others
• noted overly-repetitive sound
• noted some awkward pauses in speech for the hyphen
• added some adjectives to the modifiers list
• heard "alternative-pods", "fluffy-networks", "negated-cats" occasionally, subject to chance
• modified loop to use faster tempo but only initiate next utterance every 4 beats
• defined an empty drum part function
• added call to drum part every beat
• evaluated midi program change message to put two melodic drums on midi channels 1 and 2
• added expressions to drum part function to play both drums rhythmically, as a function of beat number mod 16
• created empty claims list
• added a few silly claims that could be made about the random items being named
• modified speech expression to say "[prefix]-[pnoun] are [claim]"
• heard "interesting-packets are controversial", "sly-waffles are desirable" and others in random rotation
• factored out speech part as a separate function
• modified loop to call speech part less often (to avoid excessive overlapping of utterances)
• added several new prefixes, nouns, and claims
• noticed that there was now a long time between adding a term to a list and hearing it in a random utterance
• created an empty function called low part
• registered calling of low part in the loop
• added expression to periodically low part of play a long, random note from a given scale
• evaluated expression to change midi program for channel used by low part to a string sound
• added a few higher, decorating notes to low part
• added more prefixes, nouns, and claims
• created an empty lead-in list
• added "and", "but", "however" to lead-ins
• modified speech expression to begin utterances with a lead in
• heard "and inquisitive-hackers are to be desired, but quasi-cats are unrelated" and others
• added new empty functions high part and interesting part
• registered these functions to be called in loop (with mask based on beat number)
• added playing of note with random pitch and duration selection to each function
• evaluated midi program change expressions to give each part a distinct voice
• added several more items to the lists used in utterance construction
• stopped main loop
• added checks for beat being greater than various specific values for all non-speech parts
• restarted loop
• heard a single utterance with no background music
• heard several utterances over low part
• heard several more utterances over low part and drum part
• (and so on)
• added a new melodic part called another part
• added several more pieces for utterance construction
• removed several silly terms, keeping the more intelligent sounding ones
• noticed that the utterances were more interesting if they seemed to express a personal belief
• added "i feel", "you shouln't believe", "i know" to lead-ins list
• heard "i feel random-constructions are unending"
• noticed utterances were particularly interesting when they seemdd to express a personal belief about the system itself
• added more references to words related to generative content, repetitiveness, randomness, and intelligent machines
• tweaked parameters for a few more hours
• stopped main loop
• fell asleep (the sun had risen a while ago)

[edit] "bilingual livecoding"

• launched impromptu
• opened included osc example

• created a new text buffer
• launched puredata
• opened included osc example
• created dumpOSC object connected to a routeOSC object
• added /pitch to router, connected to a number box for visualization
• created a sendOSC object, disconnected from the rest
• added several boxes to allow sending a random midi pitch value via the /pitch address to the rest of the program
• watched received number change in the number box
• added expressions back in impromptu to send more random pitches to the pd program
• added a sine oscillator controlled with frequency controlled with data from /pitch messages
• added a new address /bang to the router and used this to control a line generator
• instructed line generator to ramp from 1 to 0 over 125ms, used this as amp for the oscillator
• connected dsp chain to dac
• added expressions in impromptu to send the /bang message
• heard pulsing notes on demand
• added /decay and /slide patterns to router
• added logic so that values sent to /decay would adjust the length of the line triggered by /bang
• added logic so that values sent to /slude would adjust a new line used to slide the pitch of the main oscillator
• crashed pd (accidentally)
• recreated pd program from memory, cleaner this time
• created temporal recursion loop in impromptu
• started recursion
• added expressions to send /bang rhythmically
• heard regularly pulsing notes
• adjusted note length via /decay from impromptu
• added expressions to send numbers from a global list of pitches
• heard repetitive arpeggio
• added expressions to populate new pitch sequence from random notes from a random chord in a given key every 16 notes
• heard shifting arpeggio of interesting notes
• replaced sine oscillator in pd with more complex expression involving lfo-controlled phase shift and wrapping to create overtones
• added freeverb unit to dsp chain
• added short delay to right channel
• modified new sequency selection to happen on the 1st, 32nd, and 56th step of a 64 step pattern
• added bandpass vcf with sweep triggered by /bang and lengthened by /decay to dsp chain
• added /q pattern to router and used it to control resonance of filter
• added expressions in main loop in impromptu to periodically update /q
• added /kick and /snare patterns to router
• created simple kick drum by sweeping the freqency of a sine oscillator by the fourth power of a line generator (with 10Hz high-pass filter after)
• connected kick drum to dsp chain
• clicked it a few times, heard the drum
• tweaked line generator
• connected kick drum with /kick pattern messages
• added expressions in impromptu to send /kick message every 4 steps
• added expressions in impromptu to send /snare message rhythmically in a typical snare pattern
• created simple snare drum in pd by ramping the volume of filtered noise, triggered by /snare messages
• connected snare drum to dsp chain, immediately heard decent rhythm
• tweaked both drum rhythms in impromptu
• added masks to /pitch and /bang messages
• added occasional octave-up and octave-down notes
• adjusted overall tempo, exploring half and double speed
• commented out /kick messages and set /snare to fire every step
• heard snare roll
• set /kick to fire every step
• heard heavy drum roll
• set masks back to original rhythmic pattern, re-evaluated
• heard nice, sharp transition to main rhythm
• tweaked numbers in pd
• crashed pd (by attempting to save!)
• recreated entire patch from memory
• tweaked numbers in pd
• tweaked numbers in impromptu
• experimented with different oscillators and lfos in pd
• saved everything without crashing this time
• stopped main loop
• fell asleep (the sun had risen a while ago)

[edit] "music without sound"

no time to write this up right now, but, at a high level...

• created an impromptu program to send /kick /snare /bass and /lead osc events, with reasonable parameters and patterns
• created a processing program to visualize these events with lines, circles and boxes with exponentially decaying size from trigger time and position given by pitch
• did the above stuff in parallel between the two languages, using the processing visualization to tweak patterns and pitches in impromptu (without every listening to them)

[edit] "music without sound, with sound this time"

no time to write this up right now, but, at a high level...

• started teaching a friend how to use chuck
• found example of how to wait on osc events
• loaded the impromptu program from "music without sound"
• modified it to send osc events to friend's laptop
• coached friend in mapping osc events to reasonable synthesis methods
• heard decent music come from an event stream that was design only on the basis of how it looked (in terms of code and event visualization, but never sound)
