Changes in Tidal 1.0.x
Under the hood, Tidal 1.0.0 is a major rewrite. If you're used to previous versions, this will mostly be evident in terms of new functionality. But there are some breaking changes too.
Below is a growing list of changes and additions. I (User:Yaxu) have tried to thank people who have done/contributed towards things, apologies to those I've missed. Things not marked are probably entirely my fault.
Name changes, new functions, changed behaviour
- The old
scalehas been renamed to range
- scale is now used to specify musical scale
protateand friends has been replaced with rot
- New function fix for manipulating control patterns with matching control values
- New function mono for making a pattern monophonic (thanks bgold)
- New function smooth for turning a discrete/digital numerical pattern into a continuous/analog one, by interpolating between the values (thanks bgold)
- Chord names can now be put into numerical patterns, e.g.
n "c'maj e'min". The old
chordPhas been removed.
discretiseis now known as segment
eis now known as euclid
breakOutis now known as arpeggiate
- Functions generally standardised into being 'slow', e.g. scan n will work over n cycles, not squeeze the whole buildup into a single cycle.
- Functions that only worked on one numerical type generalised to work on any where it makes sense, e.g. rand can now be used as a pattern of time/rational values as well as double/floating point values (thanks msp)
- select functions for choosing between patterns with a pattern of floats
- wchoose weights no longer have to add up to 1
- weave' is now known as weaveWith
- solo now does a 'true' solo. I.e. there is now also unsolo.
- You can now run a cycle immediately, once, with once
- Experimental transition interpolate for merging between new and old values
Other new features
- Tidal now takes input from OSC and MIDI - see Controller Input
- This means you can send numbers and strings into tidal to be used as control values, function parameters, or parsed sequences
- 'Show' instance for patterns (and control patterns) is now more readable
- If you treat a control pattern as a number, you'll be manipulating the
(s "bd" # n "1 2") + 3will add 3 to both 1 and 2.
- More parameters are patternable, e.g. sometimesBy
- The parser can now produce binary (boolean) patterns where euclidean rhythms produce true and false values not, true and silence. Useful for use with e.g. sew and struct
- Configuration is done via a boot script and not environment variables
- Documentation has moved to the wiki you're looking at right now (thanks to many, including kindohm)
- What we used to call a 'param pattern' is now called a 'control pattern'
Tempo and scheduling changes
The way patterns are combined has been reworked:
- The old 'structure comes from the left' adage no longer applies - you can now control where structure comes from
- The behaviour of
#works the same as before, but is now an alias for
>|, rather than
|=|(which no longer exists).
- tidal-midi is not currently working (but midi is still working great via superdirt)
- tidalink is not currently working (should be fixed soon)
- classic dirt is not currently supported (should also be fixed soon)

Internal and dev changes
- Switched to system.random for random number generation (thanks d0kt0r0
- MiniTidal moved into core tidal repo (thanks d0kt0r0)
- Started on a unit test suite (thanks vivid-synth, msp, nini-faroux and co)
- More lawful Applicative and Monad instances for Pattern
- Definition of <* and *>, that work like <*> but using the structure on the left or right
- <*> now uses structure on both sides
- innerJoin and outerJoin for 'flattening' patterns of patterns - works like join but taking structure from the inner or outer pattern respectively.
- Patterns are now flagged as either analog or digital
- Tidal is generally a single process, multithreaded thing, rather than multi-process as before
- The websocket tempo protocol has been replaced with an OSC based one
- The modules have been extensively reorganised, e.g. Strategies no longer exists, but Pattern, Core, Control and UI do.
- Compiles without warnings
- Better stack support (thanks tonyday567)
- Fleshed out datatype structure (thanks tonyday567)
- Tidyier travis builds with more haskell versions tested (thanks tonyday567)
- New function inv for inverting a binary (boolean) pattern
- Calculation is done based on hZ rather than calculations/cycle. By default it tidal runs at 20 calculations per second.
