Have you ever found yourself in the middle of a synth session, wanting your patch to sound "warmer", "denser", or "more like vintage analogue tape", but ended up hunting through MIDI CC charts or menu dives trying to remember which knob controls envelope decay versus filter resonance?
Translating musical emotions and sonic ideas into raw parameter numbers (like setting CC #74 to 42 while boosting CC #71 to 85) is one of the biggest creative speed bumps in hardware music production.
Today, we are excited to release the AI Sound Designer Assistant directly inside closeby.1! Powered by Google Gemini and deep Web MIDI hardware integration, the AI Sound Designer translates natural language prompts—and one-tap studio macros—into instant, real-time MIDI parameter tweaks for your physical hardware synthesizers.
What is the AI Sound Designer Assistant?
The AI Sound Designer Assistant is an intelligent slide-over drawer built directly into closeby.1's instrument interface. It understands the exact MIDI CC matrix and hardware capabilities of your connected synths—whether you're tweaking an Arturia MicroFreak, Behringer Pro-800, Novation Bass Station II, or custom gear profile.
Instead of manually turning knobs or searching for parameter numbers, you simply describe the sound transformation you want in plain English (or tap one of our curated Studio Quick Macros). The assistant computes the optimal parameter adjustments and streams the CC changes directly to your synth over Web MIDI, providing a concise 1-2 sentence musician-focused breakdown of what changed and why.
Key Features at a Glance:
- Natural Language Sound Sculpting: Type intuitive prompts like "make the bass thicker and punchier", "roll off high frequencies for a cozy pad", or "add subtle pitch modulation for a lofi vibe".
- Instant Web MIDI Hardware Execution: Parameter tweaks are sent to your hardware synth in real time via Web MIDI, updating physical or internal controls instantaneously.
- Studio Quick Macros Panel: Eight curated one-tap macro cards (Warmer 🔥, Lofi 📻, Cozy ☕, Dreamy ☁️, Aggressive ⚡, Brighter ✨, Thicker 🏋️, Plucked 🪕) for rapid live tweaks during jams.
- Transparent Modification Readout: Every response displays a detailed breakdown card listing each modified MIDI CC number, parameter name, and exact numerical value sent.
- Secure Cloud Trial & Custom Key Support: Enjoy 5 free trial requests on your account (synced securely to your cloud profile), or plug in your own free Google AI Studio API key for unlimited sound design sessions.
Step-by-Step Workflow: Sculpting Sounds in Practice
Sculpting hardware patches with the AI Sound Designer is seamless and non-destructive:
- Connect Your Hardware Synth: Select your active synthesizer profile in closeby.1 and ensure Web MIDI is connected to your hardware unit.
- Open the AI Sound Designer: Click the "✨ Sound Designer" button on the synth header bar to reveal the slide-over AI drawer.
- Type a Prompt or Tap a Studio Macro:
- Tap "Dreamy / Ambient ☁️" to instantly open envelope attack times and soften filter cutoffs.
- Or type a custom prompt in the input bar, such as "give this lead a sharp percussive transient with high resonance".
- Listen to the Transformation: Watch as the new MIDI CC values update your synth in real time. The readout card confirms every parameter modified, letting you audit changes or refine your patch further.
3 Creative Applications for Music Producers
1. Instant Patch Evolution During Live Jams
Rather than stopping your performance to dive into hardware menus, tap macro cards like "Warmer 🔥" or "Brighter ✨" to dynamically transition your synth timbre between song sections without interrupting the groove.
2. Learning Hardware Synth Architecture
If you are new to complex subtractive, FM, or wavetable synths, the AI Sound Designer acts as an interactive tutor. By reading the assistant's clear explanations (e.g. "Lowered cutoff CC #74 to 45 and increased decay CC #75 to 90 for a smoother tail"), you learn exactly how individual CC parameters alter tone.
3. Rapid Genre-Shifting
Easily transform a clean digital lead into a dusty Lofi tape sound with a single prompt. The AI adjusts envelope response, LFO pitch depth, and filter brightness all at once, saving minutes of trial-and-error tweaking.
