S2400 Initial Thoughts // Damn It Sounds Good.. With A Catch

video upload by Ricky Tinez

"The Isla Instruments S2400 is an incredible sampler with tons of features original SP1200 owners' wouldn't have even been able to dream of. But should Isla have gone a bit further, or was the design process as refined as it should have been? At times while using this sampler I found myself scratching my head, and other times I found myself applauding its speed and workflow shortcuts. I'm sure the S2400 will be apart of my workflow for a month or more but i'm not sure how long it'll last until i switch it out for another sampler, or... simpler (get it?)"

ALLINAIRE - Mandelbrot vs Buchla 259e

video upload by Allinaire

"In this piece the Mandelbrot set ‘plays’ a Buchla 259e and friends (including various Max-for-Live devices). The 259e is my favourite Buchla oscillator as it contains a wealth of tones varying from a simple sine wave to chaotic digital noise - which kind of represents what happens to the points within and around the Mandelbrot set. With a 259e you can make a ton of sounds ranging from pure and harmonic, melodic to percussive, so it is perfect for this experiment.

OK, so this is the first of my explorations into the ‘sound’ of the Mandelbrot set. I’ve been thinking about and working on the idea of ‘sound and fractals’ & order and chaos for some time now. Some of my earlier work is based on these ideas and I intend to release more material exploring the many aspects of these fascinating mathematical constructs and the relationship to sound and rhythm.

This first track and video is relatively simple – I basically look at various points, being real and imaginary numbers, in and around the Mandelbrot set. Depending on where a point starts there is a pattern, or orbit, related to the formula z = z2 + c where ‘c’ is the point of examination. The equation is repeated, and a pattern emerges which you can see by the lines emerging from each point. If the pattern stays within the black area then it is said to be part of the Mandelbrot set and tends to produce a pure or harmonic set of tones. Stable orbiting patterns within the set can also have different periods from 2, 3, 4, 5 and so on, as you can see in the video, these points derive from the ‘bulbs’ off the main set. These periods create the harmonic series tones. Points that are outside of the Mandelbrot set quicky become noisy and chaotic and disappear to infinity.

For this sonic experiment the movement of the original point ‘c’ and the patterns each point creates forms the origin of the notes and gates. The starting point being the fundamental frequency, and the patterns with stable orbits become harmonic ‘chords’. These are converted to midi note data. Changes in the position of the point are registered as a midi note on and off which generates gates and triggers used for the percussive tones. I convert the midi data to cv (control voltages) to drive the Buchla modular synthesiser as well as using the midi within various Max devices. The sounds on the video are derived wholly from the midi / cv data created by the movement of the original point on the Mandelbrot, there is nothing added. The ‘artistic’ aspect of the piece is derived from where I choose to sweep the points and the sounds and percussion allocated to the midi / cv data. I have more in the works exploring Mandelbrot and Fractals! I want to acknowledge that I’m certainly not the first person to do this. There are many many examples to be found on-line and in some instruments. My version is based on this original concept and application code by CodeParade found here:"

"Try it out now! Making music and sound effects directly from common fractals was an idea I though of one night, so I just had to try it out to see what it would be like. The results were really interesting and actually helped me understand even more about fractals and chaos.

"Freshly built, calibrated, and ready for action!

Here is an overview of the unit from JSI :
PROGUE is a monophonic analog DIY synthesizer inspired by the two well-known vintage synthesizers: ROGUE and PRODIGY. While both of them had their pros and cons, the goal with the PROGUE was to combine their best qualities into a single portable tabletop synthesizer.

The prime focus was maintaining those specific sound characteristics that still makes them desirable today and to add some of the features we always thought they lacked.

From independently modulated PWM and Oscillator Gate Sync to passive High-Pass Filter and precise Fine-tuning of the Oscillators, PROGUE delivers it all without forgetting the modern self-evident functionalities like Polychain via MIDI.

This unit was built using the pre-populated SMD PCB, so surface mount components (99% of the synth other than pots, jacks and switches) are all very clean.

Includes brand new Triad power supply"

Elta SOLAR50 + OTO Bim & Bam // HUGE sounding pocketable ORGAN

video upload by Dexba

"I've recently fallen into the pedals craze and yeah, I couldn't resist both the design and the vintage crunchiness of the OTO line, so when I got a good deal on the pair I went for it!
Both are amazing, even though you have to dive a little deeper in order to get exactly the sound and feel you're looking for.
BAM was a refreshing acquisition after years of BigSky. Natural sounding reverbs with a touch of dirt (comparison with the CXM1978 coming soon 🔥).
BIM is simply the perfect delay for me. Can go from a very simple, nice-sounding delay, to a filthy lo-fi stereo grungy mess, and the modulation came really handy with the Solar50 (that's what I am fiddling with during the jam).
Solar50 was the perfect companion for these pedals, since its raw sound (not passing even through the filter, since I was using the dry stereo output).
BIM provided dimension and modulation, while BAM gave the space and that little smudging effect needed for cutting some of the harshnesses.
All in all a GREAT combo! Can't wait to get my hands on an OTO BOUM, even though I am undecided between that and the Elektron Heat mk2. We'll see!
Enjoy ✨"

video upload by MrDataline

"Download at:

This Dataline Sound Pack (DSP) features 128 Acidic BassLine Loops + 16 Classic Drum Samples. These 'Acidic BassLine' patterns were crafted on the Mssiah Bassline, a 303 Clone app for the Commodore64. Then sampled via the Octatrack. Each BassLine loop is 4 bars, with altered filter modulation for each bar.
To celebrate these samples, I have made exclusive patterns to some good old machines - which are featured in the audio & video examples and bundled with the DSP: Commodore303!

DSP: Commodore303 includes,

- Royalty Free 128 Bassline loops + 16 Drum Samples at 24Bit 44.1Khz
- Ableton Project + 8 Pattern Projects for Polyend Tracker, Digitakt, Analog Rytm & Octatrack. These projects come along with premade Patterns, Kits, Scenes and Performance modes.
- Last but not least: Source Files for the Mssiah Bassline patterns. If you happen to have a working C64 and a Mssiah cartridge, you can load up 64 patterns used in this DSP creation!
