Physical Modelling

Another experiment in using physical modelling sound synthesis. This time the model used is a system of 4 inter-connected plates. The plates are excited using variable length sequences of pre-filtered digital impulses. The frequency of the impulses is set equal to one of the first twelve mode frequencies of the first two plates. These sounds are then layered to create chords and hence the harmonic structure of the piece is derived entirely from the spectral content of the first two plates.

All sound synthesis done in SuperCollider, all numerical math done with the help of Python (using Numpy and Scipy). This is a stereo reduction of the original 24-channel version.

Extase 1

Made With SuperCollider, Python and a little help from Audacity

Extase 4 (Version)

Made with SuperCollider, Python and a little help from Audacity.

Extase 3 (Version)

Another piece (stereo version) made with a self-build physical modelling library for SuperCollider and Python. The model used for the sounds consists of two plates which are connected to each other through 6 stiff strings of different physical proportions. 

The different spectral content throughout the piece is achieved by exciting different strings and plates and, by picking up the response of all individual objects at different locations along their surface.

The excitation signals are made up from different types of filtered noise and impulses (FOF synthesis) and an attempt has been made to model / compose different types of environmental sound scenes purely using sound synthesis methods.

All sound synthesis and sequencing done in SuperCollider using Unit Lib and my custom physical modelling lib.

Beta 2 has been mastering the art of production for years, blending jazzy elements with cinematic depth to create truly immersive Drum & Bass. He’s long been one of the most exciting artists on Metalheadz, so it’s a real treat to see him back with a fresh three-tracker, ‘White Dahlia’.

The title track takes a different approach, stripping things back with organic, live instrument-driven sounds rather than the usual synth-heavy style—it’s a real breath of fresh air.

On the flip of a limited edition white 10” lathe cut, ‘Kerb Kruncher’ throws it back to the early 2000s with raw energy and gritty textures, delivering some proper nostalgia.

Closing things out, ‘Carter’ is classic Beta 2—deep, moody, and dripping in atmosphere, with those signature noir vibes and rich double bass tones.

DROOGS017 makes its return with a 12" courtesy of Quartz in the form of a razor-sharp two-tracker, showcasing his trademark precision and stripped-back engineering.

The A-side, “Duplicity,” is a masterclass in minimalism cold, skeletal, and immersive, driven by tight basslines and subtle rhythmic shifts. Quartz proves that less truly can hit harder.

On the flip, “Black Prism” a collaboration with Overlook dives into raw ’90s techstep territory. Choppy breaks and haunting stabs build relentless pressure before giving way to a surprisingly blissful finale.

Quartz continues to cement his reputation as one of drum & bass’s most distinctive modern voices.

Here we go... FINALLY!!! This mixtape has been around the globe many times & now here you have it, a copy of thee actual master. Armando Gallop aka Land Of Confusion Live on 102.7 FM WBMX, Chicago. Big upz 2 my GodFather, Farley "JackMaster" Funk 4 introducing the Chicago airwaves 2 Armando. Farley has done a lot in mentoring other DJ'z who became HUGE DJs/Producers/Remixers, 1 being Steve 'Silk' Hurley.
I also want 2 give BIG prop'z 2 the man who recorded this mixtape, Mario Luna, The man behind the series of books 'Beyond Heaven'. If you're a TRUE CHICAGO HOUSE HEAD, these books r a MUST HAVE!!! I also want 2 give BIG PROPZ 2 Bill Schmilke of Unscene Records, Chicago.
This truly is a master class mixtape of the legendary Armando. I would have 2 say he was & still is the Prince of Chicago Acid House right behind Phuture.
Now I know you're going 2 dig this!!! As alwayz, downloadable... Why??? Cuz I can't take all these tapez with me 2 Heaven... & this is my way of giving back 2 my studentz & simply 2 those that didn't live it like I did.

God Bless,

All The Game EP

All The Game

All The Game [V Recordings]

This track demonstrates an SC based environment for modelling coupled string vibration using a hybrid finite difference/modal approach. In SC you can specify the setup of the string network, i.e. how many strings you want to include, their physical parameters and boundary conditions and their inter-connection location. This information will then be send on to Python, which translates this in a suitable finite difference formulation in state space form. This means the complete system can be put into one giant matrix, which can be diagonalized to find the eigenvalues and eigenvectors of the system. From the eigenvalues the modes and damping constants of the complete system may be determined easily. This information is send back to SuperCollider and is used to provide the filter coefficients of a parallel bank of second-order resonators which when excited will generate the sound output.

The advantage of the finite difference formulation is that one has a lot of freedom in assembling the network of inter-connected objects and determining the inter-connection locations in that it is a very general approach. The downside is that the computational complexity of finite difference based models is usually rather large, making it unsuitable for real-time applications. This is where the diagonalisation to modal coordinates proves to be very valuable, since you end up with a large array of filter coefficients representing the modes of the complete system. One can then discard all modes which have a minor contribution (i.e. by excluding all modes below a certain threshold amplitude) and hence end up with a hugely more efficient model. Another nice feature of having your system expressed in modal coordinates is that it becomes possible to use simple second-order resonators readily available in SuperCollider (or any other audio environment for that matter) to simulate the system. The limitation of the modal formulation is that it is only possible to simulate linear systems though. Python was used because it has an excellent library (Numpy and Scipy) for doing more complex numerical computations (i.e. support for sparse matrices, diagonalising matrices, solving large linear systems efficiently), which are not possible to do (efficiently at least) with SuperCollider.

For this composition the environment was used to model two inter-connected strings. The strings are fixed at one side and free and inter-connected at the other side. The physical parameters of the string system are tuned so that the sound output sounds (pleasantly) harmonic, which was a long trial and error process. The string network is excited using various synthetically generated excitation signals.

All sound synthesis/design and sequencing was done entirely in SuperCollider. The overall structure of the composition is fixed, although micro-fluctuations will occur everytime the piece is played making every listening experience a little unique (at least that is the idea).
