STRÄNG | A single oscillator passed through a convolution filter in real time as you play, so the filter is part of the voice, not the sample that is activated. The filter changes depending on the note, so repeated notes sound different rather than identical.
STRÄNG A living classic of subtractive synthesis
It all started with a single oscillator and a year of trying to create something more organic than a traditional subtractive synthesizer. What pushed me to this point was the use of real-time convolution for each voice. This gave the sound volume, making it part of the sound itself, rather than a sample triggered on command.
Now the oscillator has company: a shadow layer, a subwoofer, a string model, and SPARKLE. I added components to get closer to the sound I was hearing in my head, and they all feed into the same chassis.
A new look. And sympathetic resonance
Skins change the entire appearance: the background, controls, frames, and backlighting. And SYMPATHY adds sympathetic resonance: notes you hold sound with each new note, like a piano with the pedal pressed.
