US Market. No publisher influence. > **Key Insight:** midi-sink is a music app by Vibetuned. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Music | | **Developer** | Vibetuned | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 18d | ## Metadata & Market Performance - **Publisher:** Vibetuned - **Category:** Music - **Target Audience:** Professional musicians and sound designers using MPE hardware controllers who require a visualizer or a touch-based MIDI input surface. - **Platforms:** iOS - **Version Reviewed:** 2.0 - **Report Date:** 2026-10-27 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 6810793641 - **Bundle ID:** com.vibetuned.midi-sink - **Data Window:** Analysis based on signals collected up to 2026-10-27 ## Executive Snapshot **What it is:** midi-sink is a specialized MPE controller and visualizer for iPad that maps touch gestures to MIDI data and mathematical ink-marbling effects. **Why users hire it:** It removes the friction of mapping complex MPE hardware gestures to visual feedback, providing a consistent, high-fidelity interface for professional sound designers. ## App DNA (Features & Intent) - **[Differentiator] Mathematical Marbling Engine:** Models a tray of water with ink using area-preserving transformations to maintain crisp rings during gestures. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Differentiator] MPE Instrument Controller:** Translates touch gestures into MPE master channel data including pitch, pressure, and sustain pedal control. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Standard] Decent Sampler Integration:** Loads external sample libraries to provide custom sound generation within the app. * *User Intent:* Users value self-expression and personalized experiences. ## Market Position {#market-position} midi-sink occupies a specialized niche in the Music category, serving as a professional-grade MPE input surface rather than a consumer-facing instrument. Its open-source model differentiates it from proprietary visualizers that typically gate advanced MIDI routing behind paid tiers. ## Monetization Strategy - **Model:** Free - **Tiers:** Free software (AGPL-3.0) - **Analysis:** The app is distributed as free, open-source software with no visible monetization or paid tiers. ## SWOT Analysis {#swot} **Core Strengths:** - Mathematical marbling engine ensures area-preserving transformations that maintain visual crispness during high-velocity gestures. - MPE master channel integration allows precise control over pitch, pressure, and sustain, mapping directly to professional hardware workflows. - Open-source distribution (AGPL-3.0) eliminates the cost barrier for sound designers experimenting with MPE input surfaces. **Growth Levers:** - Expanding the Decent Sampler integration to include pre-mapped instrument patches could lower the barrier to entry for non-professional users. - Developing a dedicated community gallery for sharing performance replays could build a network effect around the visual output. ## What's New - **Latest (v2.0, 5 days ago):** Version 2.0 introduces a Decent Sampler engine, the Anod electric discharge medium, five new instrument layouts, session replay, and 8K-capable print exports. ## App Momentum (Maintenance) {#momentum} - Shipped Decent Sampler engine integration. - Introduced Anod electric discharge visual effects. - Added five new instrument layouts. > **Cadence:** 2 total versions · 1 majors in last 6 months · 5 days since last update · 37 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} midi-sink is a music app that is completely free. > **Bottom Line:** midi-sink provides a high-fidelity MPE input surface that serves professional workflows, but its reliance on external sound generation limits its reach. Integrating pre-mapped sample patches would unlock the app for a broader audience of sound designers. **Best for:** Professional musicians and sound designers using MPE hardware controllers who require a visualizer or a touch-based MIDI input surface. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship pre-mapped Decent Sampler patches because the lack of internal sound generation is a primary barrier to entry → increase user retention. ### Outlook: Stable The market for MPE-compatible tools is consolidating around professional hardware, and midi-sink is well-positioned as a lightweight, open-source utility. Continued investment in sampler integration will be necessary to maintain relevance against proprietary software bundled with high-end controllers. - 🟢 The latest release (v2.0) introduces a sampler engine, signaling active feature investment rather than maintenance-mode stagnation. - ⚪ The app's reliance on external MIDI routing means its growth is tethered to the adoption of MPE hardware controllers in the broader market. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **midi-sink** (this app) | N/A/5 | N/A | Vibetuned | | [SyncTimer - Ensemble Stopwatch](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) | 5.0/5 | Thrilled | Sebastian Suarez-Solis | | [ヨルシカ](https://marlvel.ai/apps/com-yorushika-sp) | 4.8/5 | N/A | Fanplus, Inc. | | [あいみょん](https://marlvel.ai/apps/net-aimyong-sp) | 4.5/5 | N/A | Fanplus, Inc. | | [イントリズム](https://marlvel.ai/apps/jp-rc-into-rhythm) | 3.5/5 | N/A | RedinC | | [クリープハイプ](https://marlvel.ai/apps/creephyp-sp-browsingapp) | N/A/5 | N/A | Fanplus, Inc. | ## Company Profile - **Developer:** Vibetuned ## Data Sources & Links - **App Store ID:** 6810793641 - **Sources:** App store metadata. ## Related Intel Reports - [*SyncTimer - Ensemble Stopwatch*](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) (Sebastian Suarez-Solis) · 5.0/5 Rating | Excellent Sentiment - [*ヨルシカ*](https://marlvel.ai/apps/com-yorushika-sp) (Fanplus, Inc.) · 4.8/5 Rating - [*あいみょん*](https://marlvel.ai/apps/net-aimyong-sp) (Fanplus, Inc.) · 4.5/5 Rating - [*イントリズム*](https://marlvel.ai/apps/jp-rc-into-rhythm) (RedinC) · 3.5/5 Rating - [*クリープハイプ*](https://marlvel.ai/apps/creephyp-sp-browsingapp) (Fanplus, Inc.) · N/A Rating - [*マカロニえんぴつ*](https://marlvel.ai/apps/com-macaroniempitsu-fc) (Fanplus, Inc.) · 3.1/5 Rating - [*¼ learn sight read music tutor*](https://marlvel.ai/apps/learn-sight-read-music-tutor) (Alain Kong) · 4.5/5 Rating - [*100.1 Jack FM*](https://marlvel.ai/apps/100-1-jack-fm) (NRG Media) · 1.0/5 Rating - [*100.1 WJRZ*](https://marlvel.ai/apps/100-1-wjrz) (Beasley Broadcast Group) · 4.8/5 Rating | Excellent Sentiment - [*100.3 The Wolf*](https://marlvel.ai/apps/100-3-the-wolf) (SummitMedia, LLC) · 4.1/5 Rating ## Frequently Asked Questions {#faq} ### Is midi-sink a standalone synthesizer?
