Project description:
"Title: JUCE Audio Developer – Potential Upcoming Project (ToneSteer MVP)

⸻

Description:

We are seeking an experienced JUCE C++ developer for a potential upcoming project to build the MVP of ToneSteer, a Windows 10+ desktop music app.

The app combines:
• A monophonic step sequencer (up to 4096 steps)
• Real-time vocal pitch tracking overlay
• WAV export of mic input
• Lemon Squeezy license validation

We already have a full technical spec + pseudo-code ready (attached PDF). The selected developer will be able to work directly from this document — no need to design features from scratch.

⸻

Core Requirements
1. Step Sequencer
• Click-to-place and drag-to-resize notes
• Vertical pitch lanes: continuous chromatic scale (C3, C#3, etc.)
• BPM adjustable, save/load melody, MIDI export optional
• Guide tone playback with selectable instrument sound
2. Pitch Tracking
• Single-screen layout (sequencer + pitch overlay together)
• Mic input pitch detection with ≤150 ms end-to-end latency (MVP target; possible optimization later)
• Color-coded overlay: Green (±threshold cents), Yellow (flat), Red (sharp)
• Accuracy threshold adjustable 0.05–0.25 semitone
3. WAV Export
• Records mic to 44.1 kHz / 24-bit mono WAV
• Saves to user-chosen location
4. Licensing
• License key prompt at first launch
• Lemon Squeezy API validation
• 7-day offline cache for valid keys

⸻

Deliverables:
• Compiled Windows installer (.exe)
• Full JUCE source code with comments
• Build instructions + quick start PDF
• Passes acceptance tests in the attached spec

⸻

Skills Required:
• JUCE framework (expert level)
• C++17 or later
• Step sequencer or piano-roll UI experience
• Pitch detection (YIN, autocorrelation, or similar)
• Audio file export (WAV)
• REST API integration

⸻

Budget: $1,200–$1,850 USD (fixed price)
Timeline: 3–4 weeks from start

⸻

To Apply, Please Include:
1. Examples of JUCE audio apps you’ve built.
2. Step sequencer or pitch detection projects you’ve completed.
3. Confirmation you can deliver all features in the attached spec within budget and timeline.
