WORLD OF MUSIC ; PORTABLE KEYBOARD - Latest Portable Music Keyboards, Synthesizers and Music News

Green Noise has introduced Saucillator, a free app for iOS and Android that lets you create and play your own custom synthesizers and instruments.

What they have to say about it:

“Inspired by the Korg Kaossilator and Moog synthesizers, Saucillator transforms mobile devices into a platform for creating and playing digital synthesizers. Users use the touchscreen to manipulate oscillators and effects, and can also do live-looping and recording. Our goal is to be beginner friendly while at the same time offering all the deep, complex features traditional synth users love.

Users are able to play custom synthesizers using the x-y axes of the touchscreen. The x-axis corresponds to amplitude (volume) and the y-axis corresponds to frequency (pitch). Playback can also be looped, recorded, and EQed using a Parametric EQ.

On top of performing, users are able to create their own custom synthesizers, which consist of a custom timbre and user-defined effects. A variety of timbres are included: Sine, Square, Saw, Pulse, Noise, Theremin, “Singing Saw”, “Electric Eel”, and “Starslide.” These, as well as any user-created synths, can be mixed and matched at different harmonics, amplitudes, and phases to create custom sounds.

Each synth has customizable fx parameters as well, including Envelope (ADSR – attack & release), Vibrato LFO (rate & depth), Tremolo, Delay, Distortion, Parametric EQ, and Note Lag (Portamento).”

You can also export your designs to share with others.

Saucillator is available now, for iOS & Android, as a free download.

UJAM let us know that Finisher RETRO, a comprehensive collection of vintage-inspired effects, is available as a free download from September 25 through December 7, 2025.

Finisher RETRO combines analog filters, delays, reverbs, tube drive, legendary choruses, phasers, and tape saturation.

“Vintage hardware gear is hard to come by and harder to use. There are software emulations, but they can be pricey,” says UJAM COO Wolfram Knelangen. “So, for a limited time, we‘re giving musicians an opportunity to explore vintage sounds with this gift that sounds amazing, with virtually zero learning curve, and a chance to get to know UJAM along the way”.

Features:

• Tape Aesthetics — saturation, wow & flutter, hiss, dropouts, echo
• Vinyl Character — crackle, rumble, stylus noise, lo-fi instability
• Analog Gear Coloration — tube saturation, spring & plate reverb, analog delay
• Early Digital Artifacts — bitcrushing, sample rate reduction, early digital chorus/reverb
• Classic Modulation — phasing, flanging, tremolo, vibrato, rotary speaker effects
• Noise & Degradation — noise layers, ambient hum, environmental patina

Finisher RETRO is available now in VST 3, AU 2, and AAX formats for Mac and PC, with native support for Apple Silicon. The plugin is free to download from September 25 through December 7, 2025.

Boochow Instruments has introduced a new web app that lets you create custom user units (oscillators, modulation FX, delay FX, reverb FX) for the Korg NTS-1 mkII using Pure Data.

Pure Data to NTS-1 mkII is a free Web-based application. It assumes that you know Pure Data, which is a free, open source visual development environment for making multimedia patches. To use, you just drag your patch to the converter.

Features:

• Convert .pd patches into ready-to-use KORG NTS-1 mkII user units
• Supports not only oscillators but also modulation, delay, and reverb effects
• No need to install any software — runs entirely in your browser
• Supports key parameters such as pitch, shape, and effect controls

Pure Data to NTS-1 mkII is available now as a free Web-based application.
