Spot the illusion.
"Vintage Roland System 100 101 keyboard. Owned this for years (I own 2). Originally bought from Japan. Due to its age (50) the paint is showing some age which is unfortunately very common with this particular model of Roland Synths. This is an excellent mono synth, and very powerful. This is the building block of the Roland System 100 series which includes the 101,102,103,104 and the 109 speakers."

Novation Nova 2025 Review 👉 The Better JP-8000? | A Hardware Perspective | The DoubleSaw
video upload by Kosmokatze
"The Novation Nova Desktop is over 25 years old — yet it’s still used, discussed, and loved by many electronic musicians.
In this video, I take an honest and critical look at the Nova from today’s perspective:
its sound engine, workflow, modulation depth, strengths, limitations, and how it compares to other late-90s virtual analog classics like the JP-8000 and Access Virus.
This is a pure hardware-focused review.
There are no VST comparisons, no modern software emulations, and no plug-ins involved.
The goal is to evaluate the Nova as what it is: a standalone hardware synthesizer with its own character.
Whether you’re into trance, techno, ambient, or classic electronic sounds — this review looks at why the Nova still matters in 2025.

This Pine Tree Doesn’t Follow Time — It Shapes It (Deep Meditation Experiment)
video upload by Bio Music Vibrations
"The signals of a plant are difficult to interpret — especially when their sound is not naturally tuned to the human ear.
What you hear at first may feel raw, almost chaotic.
Not music as we usually understand it, but movement… pulses… living electricity searching for a voice.
In this experiment, I connected a pine tree to a modular synthesizer and did something unusual: instead of forcing harmony, I limited the system to just a few notes and allowed the tree to influence the tempo itself.
The result was surprising.
The BPM was not fixed.
It expanded and contracted organically — breathing rather than following a grid.
This reflects a simple but profound idea once described by Einstein:
time is not absolute.
Here, time is not dictated by a machine, but shaped by a living organism responding to the present moment.
The graph linked below shows the smoothed bioelectrical readings of the pine tree over time, revealing natural fluctuations and distinct states.
Because life is never perfectly stable.
It flows.
With the addition of subtle textures and gentle binaural beats, the sound opens a space for deep meditation, where the mind slows down enough to listen — not with the ears, but with attention.
This feels especially meaningful during the Christmas season.
Pine trees have long symbolized continuity, resilience, and life through darkness.
And yet, millions are cut down each year — used briefly, then forgotten.
This music is not a loud protest.
It is a quiet reminder.
A reminder that forests are not resources —
they are relationships.
Living systems that regulate climate, hold memory, and support all life, including ours.
As the sound unfolds, thoughts soften.
There is no past to revisit.
No future to fix.
Only this vibration.
This breath of time shaped by a tree.
Peace is not something we create.
It is something we remember.

I like the sound of the K1. It's got some cool samples and nice choirs, strings, bells, flutes and experimental sounds. It's a bit flat and lifeless, and not very dynamic. Maybe a poor man's Roland JD-800, but with a joystick which increases its cool factor.
On the display you can see all the patches used in each track.
