View source for 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 <source inline>scale</source> has been renamed to [[range]]
* [[scale]] is now used to specify musical scale
* <source inline>protate</source> and 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 [https://github.com/bgold-cosmos/ bgold])
* New function [[smooth]] for turning a discrete/digital numerical pattern into a continuous/analog one, by interpolating between the values (thanks [https://github.com/bgold-cosmos/ bgold])
* Chord names can now be put into numerical patterns, e.g. <source inline>n "c'maj e'min"</source>. The old <source inline>chordP</source> has been removed.
* <source inline>discretise</source> is now known as [[segment]] 
* <source inline>e</source> is now known as [[euclid]]
* <source inline>breakOut</source> is 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 [https://github.com/msp/ 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]]
* New [[arp]] function for arpeggiation
* Easy ways to send [[Custom OSC]] to systems other than superdirt
* The meaning of [[stut]] and [[stutWith]] parameters have changed to match each other.

= Interaction =

* [[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 =
https://talk.lurk.org/channel/tidal
* 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 <source inline>n</source> control, e.g. <source inline>(s "bd" # n "1 2") + 3</source> will 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 =

* Documentation has moved to the wiki you're looking at right now (thanks to many, including [http://github.com/kindohm kindohm])
* What we used to call a 'param pattern' is now called a 'control pattern'

= Tempo and scheduling changes =

* [[Interaction#Changing_tempo_with_setcps|setcps]] is now used to set a fixed tempo
* Tempo can now be patterned, using [[cps]] as a control pattern

= Pattern structure =

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 <source inline>|+|</source>, <source inline>|*|</source> has changed.
* <source inline>#</source> works the same as before, but is now an alias for <source inline>>|</source>, rather than <source inline>|=|</source> (which no longer exists).

= Regressions =

* 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)

See [[Combining pattern structure]] for full info.

= Internal and dev changes =

* Switched to system.random for random number generation (thanks [https://github.com/d0kt0r0/ d0kt0r0]
* MiniTidal moved into core tidal repo (thanks [https://github.com/d0kt0r0/ d0kt0r0])
* Started on a unit test suite (thanks [https://github.com/vivid-synth vivid-synth], [https://github.com/msp/ msp], [https://github.com/nini-faroux 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 [https://github.com/tonyday567 tonyday567])
* Fleshed out datatype structure (thanks [https://github.com/tonyday567 tonyday567])
* Tidyier travis builds with more haskell versions tested (thanks [https://github.com/tonyday567 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.
