Custom White Roland Juno-106 61-Key Programmable Polyphonic Synthesizer

via this Reverb listing
"Custom Roland Juno 106 serviced, painted, and modded by the synth spa in late 2017. This Juno 106 is super clean, works perfect perfectly, and is one of a kind. The color is cream and all the graphics, program lights, and mod wheel are all custom. Synth spa also socketed the main processor so it’s easily removed if you should ever decide to do the kiwi. The sides are Custom too but kind of wish I would’ve gone with a matte/satin finish because they’re a little overly glossy(see pictures,) but still nice. This synth is in great shape and playsas it should. If you’re familiar with this synthesizer, it’s the voice chips that can go bad but these were fully restored when this synth was customized and should continue to stay strong for a long time."

"Simple Touch is an expandable synthesizer with swappable faceplates. In this deep-dive video I'm going through all features, including hidden gems and performance techniques.
Touch 2 is an instrument designed for tactile interaction and hands-on control. It can be a thick bass, a distorting string, a delay, reverb, distortion, and pretty much anything in between. And, front panels are swappable!

🎹 Introducing the Kontrast Expressive Suite
A new collaboration between Expressive E and Dawesome — bringing Kontrast's radical image-based synthesis engine to life with 250 new MPE presets crafted by Expressive E's sound design team.
✨ Three distinctive sound worlds:
VOID — ambient, sci-fi, frozen textures
EDGES — rhythmic motion and digital kinetics
BINARY — raw 8-bit sharpness
From icy atmospheres to kinetic digital textures, each preset explores Kontrast's most radical territories and responds fully to per-note gestures: pressure, bends, vibrato, and aftertouch.
Designed for Osmose and compatible with all MPE controllers (ROLI Seaboard, Ableton Push 3, etc.), the Kontrast Expressive Suite delivers immediate, nuanced expression through image-driven sound generation.
