"This breakdown is excellent and perfectly captures the scope. I would like for you to source the assets yourself whenever possible from those recommended collections. However, I can supply them if absolutely necessary. Be sure to keep the metadata about the source, license, filenames, etc. so that we can provide the appropriate attribution in our credits. Let's execute this in the following order to keep the build stable: **1. Dependencies & Session Management:** Add LinkKit via Swift Package Manager (please avoid CocoaPods if possible). Then, implement the AVAudioSession lifecycle management and external display multi-window routing. **2. The AKWF Waveforms (Automated):** use curl or git sparse-checkout to download a curated subset of the single-cycle waveforms (e.g., AKWF_moog, AKWF_juno, AKWF_epiano) from the official GitHub repository into our project's asset directory. **3. Core Audio Engine & Sequencer:** Build the new voice protocols, the AppleSequencer implementation, and the SampleVoice drum engine. Download the CC0 808/909 samples. **4. Visualizations:** Once the audio engine is compiling and the placeholders are set, build the Metal/Canvas per-voice NodeTap oscilloscope.
