Stop guessing which track to play next. KeyBridge is the key reference tool built for DJs who want their sets to sound more polished - without memorizing music theory. Here's what the smoothest DJ sets have in common: the tracks share compatible keys. When the next track flows musically from the last one, every transition feels right. When it doesn't, something feels off - even if you can't explain why. KeyBridge gives you the rule in one tap. --- HOW IT WORKS --- Pick the key of your current track. KeyBridge instantly shows you three ways to go next: ENERGY BOOST - Lift the crowd. Same energy family, step up. MAJ / MIN - Switch the mood. Same root, flip the feel. CALM DOWN - Bring it down. Same energy family, step down. Tap any suggestion to jump there. Chain transitions. Plan your whole set in minutes. --- WHY DJs LOVE IT --- - Works 100% offline - no signal, no lag on stage - Zero learning curve - tap and go, even mid-set - Full 24-key wheel (12 major + 12 minor) - Built for speed - 15-second auto-return keeps you focused - Haptic feedback - feel the response in your palm - Designed to disappear in the booth - dark interface keeps your eyes adjusted and the atmosphere intact - Retro DJ-hardware aesthetic that looks right next to your gear - iPhone and iPad - use it in the booth, the bedroom, or the bus --- WHO IT'S FOR --- Beginners: Finally understand why some transitions work and others don't. Build your first key-matched set with confidence. Intermediate DJs: Stop relying on memory during live sets. Read the crowd, not your notes. Producers & Remixers: Find compatible keys for mashups, bootlegs, and edits in seconds. --- FREE AND PRO --- KeyBridge is free to download. Free includes the full 24-key wheel, the three core moves (Energy Boost, Relative, Calm Down), the Spectrum Drive theme and Keep Screen Awake. KeyBridge Pro is a one-time purchase that adds the advanced moves (Diagonal -1 / +1, +5, +7), all three colour themes and every auto-return option. No subscription. --- THE PROMISE --- Follow KeyBridge's suggestions for one set. You'll hear the difference immediately. Your transitions will feel tighter, your energy arcs will land, and the dancefloor will stay with you longer. This isn't a theory app. It's a live-performance companion. --- Built by a working DJ for working DJs. No ads. No subscriptions. No data collection. Ever.

Read full description

EverSpace is an algorithmic reverb designed for creating enormous spaces, evolving ambience and richly modulated echoes. Built upon the CloudSeed engine by Ghost Note Audio, its architecture draws inspiration from the algorithmic studio reverbs of the 1980s, where networks of delays and diffusion were used to create spaces that extended far beyond the limits of the physical world. Rather than attempting to recreate a particular room, hall or vintage hardware unit, EverSpace embraces the more creative possibilities of algorithmic reverb. Dense diffusion, multiple delay stages and extensive modulation allow sounds to bloom into vast, constantly moving environments — from spacious reflections and drifting echoes to seemingly endless atmospheric tails. At more extreme settings, EverSpace becomes much more than a conventional reverb. Simple sounds can be transformed into thick evolving pads, shimmering textures and expansive ambient soundscapes, with subtle variations within the reverb network ensuring that the resulting space remains alive and in motion. EverSpace can be used as a traditional send or insert effect, but it is at its best when treated as a creative sound-design tool where the reverb itself becomes part of the sound. Features ○ CloudSeed algorithmic reverb engine — a sophisticated multi-stage architecture inspired by classic algorithmic studio reverbs. ○ Early reflection and diffusion network — control density, delay, modulation and feedback to shape the initial character of the space. ○ Extensive late-reverb section — create everything from diffuse ambience to enormous, slowly evolving reverb tails. ○ Deep modulation — independently shape the movement of diffusion and delay stages for lush, animated spaces. ○ Multi-tap delay stage — adds rhythmic reflections, echoes and additional complexity before the main reverb network. ○ Integrated equalisation — low and high frequency shaping plus filtering to sculpt the colour and decay of the reverb. ○ Seed controls — regenerate the internal delay and diffusion structures to produce different variations from the same settings. ○ Interpolation modes — alter the behaviour and character of the internal delay network. ○ Real-time visualisation — waveform and frequency displays provide visual feedback as sounds enter and evolve through EverSpace.
