Mitola is a new quark I made to experiment with microtonal music. It is close in spirit to Panola, a quark for more traditional music composition.
Pretty much like in Panola, you write a score (but using integer scale degrees instead of notenames) and you can attach all kinds of properties to the notes (a pitch modifier (think: accidental), an equave (think: octave), a duration, and basically any property you can think of like “amp” or “legato” or whatever you fancy - all these properties end up in the Pbind pattern that is derived from the score.
When it’s time to realize the score as a pattern, you need to pass in a tuning (i.e. the contents of a scala file, or a filename pointing to a valid .scl file) and a root frequency (since that is not part of the scala definition). Mitola comes with a RootFrequencyCalculator utility which calculates the root frequency to pin a given mitola note in a given equave (possibly with pitch modifier) to any desired frequency.
Here’s a wacky chip tune I quickly gobbled together using Mitola and some tuning dividing the octave in 10 steps I took from the scl tuning archive (code in the mitola examples): Vocaroo | Online voice recorder
The Mitola quark has documentation and some examples for you to play with.
but sclang returns the following error (I sucssesfully installed Panola and Scparco):

RECEIVER: Microtonal counterpart to Panola
You are right, there was a missing comma in the .quark file. I fixed it now (and tried it out ). I’m sorry for the inconvencience (oh, and you don’t need Panola for Mitola to work - both look and feel very similar but as it stands they don’t share any code.)
Aaarrgh I changed something last night without testing because I fell asleep
Please remove the downloaded quarks and try again. It should work now.
Note that upgrading will not work because of a bug in the quarks system where the “master” branch name is hardcoded, whereas github nowadays uses “main” as default branch name. (It’s logged as bug #6071 already).
Hi, you were right, the brackets were wrong.
I just cannot understand why I didn’t get any errors…
Anyway, it should be really fixed now.
Thanks for the bug report!
