February 2018 - TidalCycles

by Alex McLean

Hi all, Inspired by Jarm sharing his init script full of interesting tidal snippets and shorthands in the slack.. Do you have any useful functions/shorthands/synths/samples that could be good in the next tidal/superdirt releases? If so please reply and paste/link in your tranklements. - Meaning: small possessions, bits and pieces, paraphernalia, precious possessions. Cheers Alex

Sound.Tidal.Epic.Parse.DJ

by Jeffrey Brown

I added a feature over the weekend. This email duplicates the content of this markdown file[1]. It's probably easier to read on Github, since Github is markdown-aware and most email clients aren't. The "DJ" family of parsers provide a language for applying transformations to a collection of patterns. Here is an example: ``` pat1 = pe0 "*2 _bd _sn" pat2 = pe0 "_hc" aMap = M.fromList [("pat1",pat1),("pat2",pat2)] aPat = dj (pdjm " /3 @pat1 \ \ - [(g0.9),@pat1 | ea1%4,fa2,@pat2]") aMap v0 $ aPat ``` `pat1 = pe0 "*2 _bd _sn"` creates a pattern (called `pat1`) that plays the bass drum, then the snare drum. Ordinarily, since it's got two samples, that would take two cycles; the `*2` speeds it up to fit in a single cycle. `pat2 = pe0 "_hc"` creates a pattern (called `pat2`) that just plays the closed high hat once per cycle. `aMap = M.fromList [("pat1",pat1),("pat2",pat2)]` just defines a map (called `Map`) that maps the names "pat1" and "pat2" to `pat1` and `pat2`. That's kind of an annoying thing to type, but you don't have to: evaluating `mapNames "pat1 pat2"` in GHCI will copy `aMap = M.fromList [("pat1",pat1),("pat2",pat2)]` to your clipboard (assuming you've got xclip installed). ``` aPat = dj (pdjm " /3 @pat1 - [(g0.9,s1.5),@pat1 | ea1%4,fa2,@pat2]") aMap ``` uses the DJ language. It creates a pattern (called `aPat`) that first spends three cycles (`/3`) playing `pat1`. It then (`-`) spends a single cycle (between the `[` and `]` symbols) playing `pat1` at a gain value of 0.9 and a speed value of 1.5 (`g0.9,s1.5`) while simultaneously (`|`) playing `pat2` a quarter of a cycle early (`ea1%4`) and twice as fast (`fa2`). `pdjm` parses the pattern of instructions; `dj` applies that pattern to `aMap`. Finally, `v0 $ aPat` plays `aPat` through the voice `v0`. `pdjm` is specialized to apply to `ParamMap` patterns; it lets you change `ParamMap` values as in (`g0.9,s1.5`) above. There's also `pdj`, which does not let you do that, but which can be applied to more general kinds of patterns. The `dj` function can be applied to the output of either parsers.

Random pattern

by ben.w.grange＠gmail.com

How can I select a random pattern from a list? I've tried choose, as in the following expression: d2 $ sound (choose ["[cp ~]*12"::Pattern String, "[~ cp]*12"::Pattern String]), but I get the error: "Couldn't match type 'Pattern String' with 'Char'"

Sound.Tidal.Epic works pretty well now

by Jeffrey Brown

Sound.Tidal.Epic began with the simple intention of adding duration to patterns. Now it's got a bunch of other features. They are documented here[1]. To try them out, see the demo[2].

Control Ableton macros via CC

by zebrish＠hotmail.co.uk

Hi everyone, I've just started using Tidal. Yesterday I followed Kindohm's tutorial on how to set up Tidal with Ableton (on OS), so that each track in Ableton receives MIDI messages from a corresponding channel in Tidal. I can now play lots of samples I've put inside a drum rack and it sounds cool:) My question now is whether its possible to write a script that extends this logic - to control the macros of a specific sample? I'm not sure whether I should be tinkering with haskell scripts or ableton's Python MIDI remote scripts .... I think I could work out the programming given time, but I'm not sure where to get started really. If anyone has tried something like this it would be really helpful to hear your approach :0 !

Introductions + Random Question for Tidal Cyles w/ Ableton live 8 + Asking for tips for setting up live coding workshops

by Thomas Desai

Dear all, Hello! This is the first time that I have sent a message to this group so I just thought I would introduce myself a bit, my name is Tom, Paris-based, and I have been interested in Live Coding for a year or so, and have been using TidalCycles with ever increasing frequency for about six months. I intend to be as active as I can in this community, so I look forward to chatting with you all! I have started tinkering and experimenting with TidalCycles a bit more, and noticeably have been playing with it to control Ableton Synths over midi (using a neat midi server called loopMIDI). However I have noticed a problem which (maybe through stupidity) I can't resolve: Whilst in the last couple of versions of Ableton there is a very clean and clear way of setting different MIDI to different tracks, in Ableton live 8 (which I use) this doesn't seem to be the case; the result being that when I play for example m1 and m2 in TidalCycles, they will both simulatneously play on all armed MIDI tracks in Ableton live 8, rather then being able to discriminate m commands in TidalCycles to control different instruments in Ableton. I was wondering if anyone has come up against and successfully resolved this pernickety problem before? Any pointers would be great! Also, within the (to be honest quite small) Parisian 'creative code' community we are having some discussion about; 1. creating some kind of Live Coding workshops accesible to everyone; and 2. Organising Live Coding music/visual art "AlgoRave" events in some venues in Paris. Whilst the tech used would not be exclusively TidalCyles (Supercollider, Chuck, ianniX etc. welcome as well), we where wondering if anyone has any tips or input on how to successfully and harmoniously organising these types of events? Again, any input would be much appreciated. My best wishes all, Tom D

Troubleshooting 'pure now'... and another (possibly) related question.

by adam.casciaro＠icloud.com

Hello all! So, I recently posted about instantaneous clock resetting and sample launching, because at the start of a song I wanted to launch a series of long samples form the beginning, and I found my solution to that, but in the process I was recommended to try using 'pure now'... I have tried previously to use 'pure now' when trying out the 'seqP' function in the Tidal website reference guide, but I could not get it to work, and I have no idea how to work out what I'm doing wrong. I am literally copying and pasting the examples form the website: d1 $ seqP [ (0, 12, sound "bd bd*2"), (4, 12, sound "hh*2 [sn cp] cp future*4"), (8, 12, sound (samples "arpy*8" (run 16))) ] This one works fine, after I 'cps (-1)'... but then when I try this one: d1 $ (pure now) ~> seqP [ (0, 12, sound "bd bd*2"), (4, 12, sound "hh*2 [sn cp] cp future*4"), (8, 12, sound (samples "arpy*8" (run 16))) ] I cannot get it to begin playing... My secondary question is whether or not I could use this mid-performance to start a long sequence from the beginning without affecting all other sequences currently playing... if not, is there a workaround for this? Just to clarify what I actually mean by this: I want to start a few sequences of 1-cycle lengths, improvise for a bit, and then start another, longer, pre-written sequence with a length of maybe of maybe 2 or 4-cycles (using the 'slow' functions or '<>' brackets) without finding that it begins on the third cycle... I can think of a number of reasons why what I want may not be possible... but I'm hoping my intuitions are incorrect in this case. I know this is what I get for using Tidal basically like a text-version of Ableton Live, which I know it wasn't really intended for, but I prefer the text interface so much more than live GUI programs... so I am determined to persevere... Thanks in advance for you help!

Also, try this: getNow >>= \now -> d1 $ (pure now) ~> seqP [ (0, 12, sound "bd bd*2"), (4, 12, sound "hh*2 [sn cp] cp future*4"), (8, 12, sound (samples "arpy*8" (run 16))) ] On 13 Feb 2018 02:43, <adam.casciaro(a)icloud.com> wrote: Hello all!

Cycle clock resetting? ...I'm new... terminologies clearly inaccurate...

by adam.casciaro＠icloud.com

Hello! So, I have a question about using long samples... If I have, for example, four long-ish samples that I need to play in order, and I would like a way for the first one to always play first... So, kind a way to... force Tidal to take the cycle clock back to 0 when I launch the code? Does this make sense? Thanks in advance for any help on this...
