For the last couple months I have been learning Common Lisp by prototyping a tracker-influenced MIDI sequencer. It's been a lot of fun! The UI is still much too barebones but the dream (& reason for the lofi look) is to keep prototyping until I have something that would work in a hardware form-factor. Here is a short demo of it hooked up to Waves Audio Electric88.

A few ideas I'm playing around with:

• Looping on different track lengths creates evolving rhythmic textures
• Euclidean sequencing (track-set-euclidean) is a fun & quick way to generate ideas
• Side-by-side display of tracks with different ticks-per-bar
• UI is still keyboard* driven ala Trackers (* & in the future hopefully knob-driven)

"Can you clarify how classes (and really hashes) can more efficiently use keys when the initialization definition is established?"

This a great question and a fairly deep topic to be diving into if you're early in your coursework. Which will make it extra fun to try answering! However I would caution that it may not be important to know at this phase, as a fair amount of modern programming consists in trusting that the little black boxes work the way they say they do & moving on to the larger task at hand. Performance and efficiency concerns are precisely where that approach can break down & it's very valuable to be willing to open up every box, so let's attempt it. This whole topic can best be addressed by a course or a good book on data structures & algorithms. Since I've never taken a formal course I'll share the intuitions that have helped me despite that.

Let's start with what makes hashes and classes represented as hashes efficient to begin with and then mov

Phase 1: Visualize the existing Server structure

• http://js.cytoscape.org/ to visualize it
• Server Command Reference
• An OSC lib: https://github.com/colinbdclark/osc.js/ or https://github.com/MylesBorins/node-osc OR:
• Use https://github.com/crucialfelix/supercolliderjs ? Looks kinda dead, could also use raw OSC
• Project on SC board: supercollider/supercollider#283

Phase 2: Manipulate the graph!

• http://jsonpatch.com/ for manipulating the structure? would need an intermediary layer which maps the patch to the appropriate Server Command
