AA 1 Sem 2 week 11

This weeks exercise was create sounds via the spectral bidules in Plogue. The above screenshot of the patch shows what I first used to create the samples in the mp3 at the bottom of this blog, (all were made from an oscillator with its wave type set to noise).

In the next patch, pictured below I tried running a loop of the mp3 sample (below) as well as a version of the same sample reversed and looped. One problem I found with this set up where the magnitudes and frequencies of both samples were multiplied and the merged was that the output of the signal clipped immediately, so much so I had to add a gain bidule in which I cut the amplitude by an absurd amount. While at home and pondering this patch, (Icould work on it at home as the trial period had lapsed) I have come up with an approach that I will try out but wont be in time for this blog. The plan is to have white noise in one babooche player, whilst the other will have a sample consisting of a number of sine waves, (possibly configured similar to the harmonic series), the sign wave samples will then be subtracted from the noise sample. Other aspects to this could include the use of magnitude and frequencies gates as well as bringing in samples from Spear which have been manipulated.

CC 1 Sem 2 week 10b

This week’s exercise in CC1 was to elaborate on last weeks samples. This week, working with Fred May, in addition to running the guitar through the Mbox and adding effects, we linked the modulation of an oscillator running into a parameter modulator (abs) to both the pan of one of the channels in the mixer as well as to the wet/dry of the phase bidule. Two recorders were also attached; the first was a direct line out from the Mbox bidule which we used to record samples that were played back into the system using a Rewire of Live Bidule. The second recorder was used to record the entire performance. Above is a picture of the bidule patch we used whilst below is a screenshot of the Live window.

AA 1 Sem 2 week 10

This weeks exercise was to make up an Additive synth in Plogue's Bidule. After doing the readings I made up the synth above which had six oscillators with the settings for phase, amplitude and which harmonic being adjustable. I had intended to include an ADSR on each of the oscillators but didn't quite know how to attach it as it doesn't have a simple input and output, instead it has triggers and gates which was a little confusing. (I am planning on going over the tutorial on building the Juno synth done earlier this year, hopefully this will show how to add an ADSR). The first the sound examples are using the patch above whilst the last was using the patch below which was suggested by Tristan Louth-Robins.

CC 1 Sem 2 week 9

This weeks exercise was to work with a partner and to route an instrument through Plogue's Bidule via the Mbox. My partner was Darren Slynn and we ended up downloading the bidule patch and playing around with it. We ended up keeping the Mono ITU Mixer, which was configured for surround sound and just routed each channel into a stereo recorder. We also played around with different effects. The sample mp3 below has a delay, two different phasers, a reverb and a pitch shift connected. During the performance, approx. two thirds of the way in tone of the phasers was played around with to give the piece a little more variety.

AA 1 Sem 2 week 9

This week the class investigated FM synthesis using Plogue's Bidule. I found the Miranda reading to be the most helpful as the other reading just seemed to be going over formulas for calculating band width. Any way from just the basic FM synth patch shown to us in class I found a number of interesting sounds, the number of different settings is incredible when you take in to consideration all the possible combinations of merely just the wave patterns let alone the variable settings (freq. and amplitude).

The first three examples were done on the above FM synth while the last is on the synth below. Also see below the mp3 sample of the sounds.

Forum Sem 2 "The Insturment"

The instrument above is the final version of the instrument that we were required to make for the Forum. Originally I had only incorporated two of the three required aspects, these being tone generation and piezo driving, so in the trouble shooting class during the break the third was added (this being physical computing).

As can be seen above the Arduino board was used with the digital out sketch. This then could activate each of the six square wave generators that were made on the bread board using 2 4093 chips. Each oscillator also had a potentiometer and an LDR connected so as the pitch could be adjusted and the performance could be enhanced.

The signal ran out through a mono jack socket which was connected to a piezo driver which was glued to the bottom of a small cast iron fry pan. The second piezo (mic) was connected using a peg to a small metal bowl which could then be moved and adjusted to played around with the timbre.

Below is a screenshot of the Cubase MIDI piano roll which in which the sequence of notes, (which was looped) was kept simple for the purposes of this exercise. There is also an mp3 in which both myself and Tristan Louth-Robins are playing the instrument.

Unfortunately due to my files being lost when 'My Data Bus' stoped its free access, I've lost the the mp3 which had highlights of this instrument being played (we videoed it). As I cannot edit this video at home I've uploaded the entire video clip to Youtube. (approx. 5 mins duration)
