--- Do you have a comprehensive description of the language aside from the implementation? Particularly, I'd like to see a list of what each instruction does. I just looked at an interactive tutorial on Petri Nets, and don't see how this could correspond to a deterministic language; in the tutorial, any transition which has all prerequites satisfied can be taken, and I was able to select which transition happened next. Differently, in a programming language, one wants there to be always one next step to occur, so that a program is deterministic. Here's the interactive tutorial that I used: https://www.informatik.uni-hamburg.de/TGI/PetriNets/introductions/aalst/ TanScript seems to be the same basic idea, in that there is a graph of instructions, and there are 'heads' that walk along it. In TanScript, there can only be one head on any program. When TanScript is used only to encode music, it is very simple, each instruction simply playing a sound, or branching. Re-usable function/action definitions allow for more interesting compositions. Recursion is also an option. Aside from music, TanScript is also a fairly general-purpose language used for manipulating graph-structured data. A stack frame of a TanScript program has three references: one to the head, and two more to nodes of data that the program executes upon. The primitive instructions cause these latter two references to 'walk' around on the data, modifying and conditioning on it as they go. Musical instructions can be combined with non-musical programs in order to sonify them, making blindfolded debugging feasible. --- Do you know of any other languages similar to Daisy Chain and Tanscript? --- What dialect of Lisp did you implement Daisy Chain in, and how do you recommend making sure the notes play at the right time, with no delay between timer events and audio? Me and a friend are about to re-implement TanScript in Pharo (a Smalltalk development environment). (Letting you know in case you have any advice, having already done something similar in Lisp.) --- Perhaps you'd like to have a real-time meeting via video to discuss where we can take these ideas further? --- Best, and thank you for your feedback, - Justin On Sun, Sep 27, 2015 at 6:14 AM, David Griffiths <dave_at_pawfal.org> wrote: > On 27/09/15 09:50, alex wrote: > > On 27 September 2015 at 09:11, Justin Northrop <justinorthrop_at_gmail.com> > wrote: > >> I can't find a video of Daisy Chain.
