Creative Computing : Synthesisers and Definations(2)

Code : My code had got some serious errors.. I am working on it..Will update it very soon..

Understanding the arguments in Sine wave Oscillator, phase, mul, add)

freq = The frequency of the oscillator. The default is 440hertz.

phase = the offset time position where the wave hits a zero crossing. The default is 0,which means the wave starts immediately

mul (multiplication) = think of this argument as the Amplitude or Volume of the wave. The default is 1.The scale or range of the interpolation (whether the wave goes from -0.5 to +0.5, or -30 to +30)

add = The frequency position from which the wave oscillates. (used mainly for Control Rate oscillation).
"It is useful when you require the oscillator to interpolate between specific values. The default add value is zero, because an audio rate oscillation moves from -1 to +1. By changing the add value to 5,the wave would oscillate between 4 and 6 if the 'mul' value remained the default of 1".

Audio Arts :
First lesson after the break and I was 10mins late, sorry david I missed my tram cause it came a minute early(very annoying).When i reached , all the microphone placements had been done.We were recording one of the ensembles from the jazz department.I learned how to communicate from the recording space into the studio when there is no listening microphone and talk back facility.The rule is to be very informative through hand movements.However I suggest you setup the talk back facility in order to be absolutely explicit,restricting any possible frustration.I also suggest to get absolutely familiar with newer version of protools.Visit this link for an overview of updates for protools LE 7.3.x

Due to the time strains with studio bookings, my timings, band members availability I could not record another ensemble.However I am using the same recording and here is a rough mix of 'Perdido"by Monk played by "The Quintet of j0hn n j0sh"

Forum : Gender in Music Technology
I hate the words "male domain" or "feminism" which was repeated several times in that 1+ hour..Personally I hate dividing people into categories,now if that is culture , language , country or SEX, it does not matter.We all are one,children of one and the continuation of one.
One of the stratagies of few ruthless people is to 'divide and conquer', a big reason why India was ruled by the same people.I really dont like to write for people to read, cause I dont like to hurt anyone, anyway now I am doing it .
Look at this cable , its a male-male s-video cable..Look at it nicely, what does it say to you..?
Stephen started the forum with his thoughts about how big the issue is in the industry.on the topic..Besides the other things interesting things he said,something which striked me was to know a little more about John Cage .It obviously did not effect what I think about him and his music.I personally can not relate to the emotions of gay men.I think they play with the rules of nature.The science says two similar magnetic poles repel each other and opposites attract. Dont know why are two similar poles trying to charge one another.
Now consider the input - output theory.What will happen if you plug output of protools into output of your amp. You will only hear the world around you.Max/Msp does not even let you do that.It wont give you the option of plugging In in In or out to out.In SuperCollider you can but what will be the result,either No sound or feedback.
But YOu do get gay cablesnow ,like this one.
Why are there less women in the field of (M) Technology.It may vary from one country to another.The way they pursue things,restrictions on women and things which women like to do.For instance I see alot of women from china (and alike) in my Computer Science lecture than from any other country. One of my mates from banglore in India has complained me about not having (p?) women in his IT profession.Shine your light F e m a l eFs on "musIc tEch",what you doing ??
Todays Presenters:
Ben, I am sure you will qualify for a white collar job ,I can see u as a good communicative teacher...With a laptop in front I felt like a man..I really enjoyed it..
Amy convinced me that she loves Music Technology and thats why she is doing it.If she would have said it one less time, I would not have believed her..
Thanks for the videos jake. Message to all the women out there from Jake Morris - "listen to bjork and get inspired".
Why are the best chefs men ?? reply your answers to Douglas Loudon (I know some worst chefs in this planet and they are men.)
I can see its a new area and women are taking there time to get into it. Regardless there are some brilliant composers and performers who are women.
One of the figures in EMU is Poppi.Replacing her presence in the forum was a tiny robotic eLecTro feMale,may be her slave,sonically capturring the whole event..Not just her, Sonia wilkie, Jasmin ward and Silver Moon are more examples of women at EMU, with Amy and Laura starting their carrier.Another inspiring figure is Fleur Green, a great percussionist and a good friend of mine.Her recent collaborations with a theatre company compelled her to buy a laptop & ProTools and compose music for kids theatre.I am not sure how far as she gone, I guess she spends more time practising marimba and other percussions.She will, I am tempting her.
It's quite interesting how individual conditions effect.A lot may depend on the up bringing of a child. Why do girls in their childhood like to play with dolls and boys with cars, for instance.. Or is it just what they are given in their hands ...! They definately get attracted to things which appeal them. Any men out there, attracted to dolls when they were small or now.. ?? get back to me please.. cause I am too,, living dolls..
Is it actually gay for a men to wear pink t shirt, dont know, may be light pink with a white rose..!
Why am i discussing this, because I have been to Mars bar twice..Liz told me its quite a liberal place and plays different music.. Both the times with Bianka and the couple [Darren = Brad].

Creative Computing : Week 5 - Unit Generators

Task : Create a synthesiser code patch that demonstrates your understanding of unit generators. The code patches will need to select a form of synthesis (such as FM, AM,Additive etc) and integrate the base components of a synthesiser including pitch,amplitude and modulators.

Audio Arts : String Recording
String instruments represent a group of instruments whose sound is produced by a string vibrating in a resonant body, chamber or sound board. The physical structure and playing mechanisms vary significantly between violins, viola, cellos, guitars and pianos.The manner in which they are played varies and includes techniques like bowing, plucking, striking, scraping or a magnetic field.
One of the most important characteristics shared by all instruments in the string family is the wide range of tonal colours that different instruments are capable of producing. This is principally due to the individual qualities of the wood used in their construction, the details of their internal design and the skill and technique of the performer.
The best position for the microphone is far easier to understand than to know how the particular instrument works .However,in order to be highly succesful, learning the frequency spectrum of the instrument, where and how the sound is produced, how it radiates into the room will help you in making better decisions.

Recording Example : For my recording exercise I invited Ruth Saffir - Lecturer in Cello and Pedagogy at the Elder Conservatorium of Music and the President of the Dalcroze Society of South Australia.She is a cellist with many years' experience as a performer and teacher. Contact : (

I remember the first time I met Ruth was outside the Elder Office. My first day of uni and she took me to level 5 (EMU) and introduced me to christian. She was my Aural teacher last year , helping me train my ears. Thank you very much Ruth, for coming to the studio and helping me out.

Microphones Used :
Beta 52 : close miked to the f -hole , left of the player
AKG 414 : close miked to the f -hole , left of the player
Newman Kmi : little far as compared to AKG from the f -hole , right of the player.
U 87 : Room microphone, 3-4 metres infront of the player at ear level.

The most levels I have used in the mix is Beta 52 and U-89, whereas the other micophones are nearly half of their levels.It sounded too bright and detailed when close microphones were up.The scratch recording I initially did, ruth pointed out it be really "dry" but then room microphone levels were quite less and it was placed parallel to the instrument nearly 4-5 metres way.After changing its placement and giving it a little more gain , I tend to really like the warmness and space reverbrations.
