SndBuf Passing args to running functions
by herman verbaeten 24 Feb '20

24 Feb '20

Hi, I'm in big trouble. I'v been trying for a long time now to change an argument in a running function. As you can see in my script i set a certain central pos ("70000")to buf.pos as a central position in my soundbuffer and i let my function LFOtoPOS circle around it. Once the "spork" instruction has started the process i can't figure out how to addresss the argument "centralpos" to change it on the fly or by another function or parameter. Some help please ... Kind regards, Herman ---------------------------------------------------------------------------------------------- me.sourceDir() + "sound.wav" => string filename; if( me.args() ) me.arg(0) => filename; SndBuf buf => dac; filename => buf.read; 1 => buf.pos; .5 => buf.gain; spork ~ LFOtoPOS(70000); fun void LFOtoPOS(int centralpos) { TriOsc lfo => blackhole; 1 => lfo.freq; centralpos => buf.pos; while (true) { 1::samp => now; (10000*lfo.last())$ int => buf.pos; } } // time loop while( true ) { 1000::ms => now; }

additional.info needed => LiSa
by herman verbaeten 23 Feb '20

Hi chucklist, Although the Ugen LiSa looks promising, it raises a lot of questions. First puzzling member: .record. Does this create a second buffer? And what’s the difference between .playpos and .valueAt? What’s the use of setting (or recording?) rampDown if this changes after changing the playback rate? What’s the difference between recRamp and rampDown? This is only a fraction of the many questions I have about LiSa. Kind regards, Herman

While loop with condition =>NOW
by herman verbaeten 22 Feb '20

22 Feb '20

Hi, In the flossmanuals i found this exemple of modulation of the freq of a SinOsc. Normally in the while() loop, between the brackets is the condition to keep the loop running. In the example it is a time. Complete confusion! Kind regards Herman SinOsc s => dac; SinOsc lfo; 5 => lfo.freq; while (20::ms => now) { ( lfo.last() * 10 ) + 440 => s.freq; }

ADSR AttackRate, decayRate, sustainRate
by herman verbaeten 18 Feb '20

18 Feb '20

Hi, I was wondering what the function is of AttackRate, decayRate, sustainRate in ADSR. Normally when using an ADSR, attack only uses time. Same for decay and sustain. Also the declaration at the end of de memeber description is not very clear to me: The \e state = ADSR::DONE after the envelope value reaches 0.0 in the ADSR::RELEASE state. Thanks in advance for your assistance. Kind regards, Herman

PhD position in Sound and Music Computing, KTH, Stockholm, Sweden
by Andre Holzapfel 17 Feb '20

17 Feb '20

Doctoral student in Sound and Music Computing KTH Royal Institute of Technology Stockholm, Sweden Project description Third-cycle subject: Media Technology The project you will work in is funded by the Swedish agency Vetenskapsrådet, and is titled “Historically informed design of sound synthesis”. Based on a forgotten treasure, the Elektronmusikstudion (EMS) collection of historical analog synthesizers from the 60ies and 70ies, we aim to create a series of digital electronic music instruments enabling different expressions and instrumental forms. Your task will be to explore the collection, to implement digital emulations of some of the instruments, and to develop user interfaces for them. You will then collaborate with artists at the royal college of music (KMH) to use these instruments within new compositions, and conduct user tests with online communities.Your work will take place at the Division of Media Technology and Interaction design (MID), in the Sound and Music Computing (SMC) team. You will collaborate with the Royal College of Music and with the organization hosting the synthesizer collection (Musikverket). In addition, you will be able to apply for short term scientific missions to visit partners in the Nordic SMC network during your studies. Supervision: The doctoral student will be supervised by: Andre Holzapfel (main supervisor), Sandra Pauletto (co-supervisor, KTH), Henrik Frisk, (co-supervisor, KMH), Dan Lundberg (co-supervisor, Musikverket).
