«Step Sequencer with Midi/Scales/Tuning capabilities» by rukano
on 16 Dec'11 09:52 inVery old code I made in my first SuperCollider years. Changed some stuff to not use environment variables. Still works... but, yeah... spaghetti code ALL the way.

Wow, I'm just starting out and I had it in mind to build something like this as a first project - looks like I'll be picking your code apart first!
It's not the best coded script, but I'm glad it can help you on your way :)
Although I'm sure you could write it more elegantly now, the fact that it's laid out logically and in "longhand" is actually helpful for me because I'm not aware of all the shortcuts yet :)
