However, it is not straightforward to achieve the necessary simplicity of a first language in a music live coding setting, for reasons largely related to the manipulation of time. The original version of Sonic Pi used a `sleep' function for managing time, blocking computation for a specified time period. However, while this approach was conceptually simple, it resulted in badly timed music, especially when multiple musical threads were executing concurrently. This paper describes an alternative programming approach for timing (implemented in Sonic Pi v2.0) which maintains syntactic compatibility with v1.0, yet provides accurate timing via interaction between real time and a \"virtual time''. We provide a formal specification of the temporal behaviour of Sonic Pi, motivated in relation to other recent approaches to the semantics of time in live coding and general computation. We then define a monadic model of the Sonic Pi temporal semantics which is sound with respect to this specification, using Haskell as a metalanguage.","PeriodicalId":88474,"journal":{"name":"El Farmaceutico","volume":"43 1","pages":"37-47"},"PeriodicalIF":0.0,"publicationDate":"2014-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79925747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building on previous work on functional modelling of musical harmony, FComp first creates a foundational harmony by generating random (but user-guided) values of a datatype that encodes the rules of tonal harmony. Then, a melody that fits to the harmony is generated in a compositional sequence: generate all \"possible\" melodies, filter them to remove obvious bad choices, pick one candidate note per chord, and then embellish the resulting melodic line.\u0000 At this very early stage, we aim to define a solid system as a foundation that can be used to further improve upon. We care especially about modularity, so that each individual part of the pipeline can be easily improved, and ease of adaptation, so that users can quickly adapt the generated music to their liking. The resulting system generates simple but harmonious music, and serves as a good case study on how functional programming enables quick and clean prototyping of new ideas, even in the realm of automatic music composition.","PeriodicalId":88474,"journal":{"name":"El Farmaceutico","volume":"63 1","pages":"11-21"},"PeriodicalIF":0.0,"publicationDate":"2014-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82690883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kristensen","doi":"10.1145/2633638.2633646","DOIUrl":"https://doi.org/10.1145/2633638.2633646","url":null,"abstract":"This paper introduces Composer, a system offering composition capabilities for live performance, requiring no prior experience with composition and programming. Current research in computer assisted composition is focused on offline composition. A composer is seen as a person that composes pieces of music which are then performed at a later date, either by the composer or an artist. There has been work done in computer assisted live performance, but the focus in that field has mainly been on the live generation of synthesizers and novel, virtual instruments and musical interfaces. Unlike existing systems, Composer is intended to be used in a live context for the composition of novel melodies. The system makes no assumptions about the user's existing experience as a composer or a programmer. Instead of giving the user unbounded freedom, the system only allows the user to manipulate key properties of the desired melodies. The constraints the user can put on the melodies are the scale or mode in which the melody is set; the tonic note of the scale or mode; the cadence of the melody; the tempo of the melody; and the relative gap-size between notes in the melody. These rules are modelled using a declarative programming model that also supports automatic enumeration of the space of valid melodies. As complete enumeration of this search space is infeasible in a live context, experiments have been performed and their results are presented, to limit the size of the enumerated space while still yielding sufficient variation in the composed pieces. Furthermore, the general system design is presented and it is discussed how choices concerning the inter-communication between components in the system helps the system to be responsive and usable in a live composition context.","PeriodicalId":88474,"journal":{"name":"El Farmaceutico","volume":"1 1","pages":"25-31"},"PeriodicalIF":0.0,"publicationDate":"2014-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86498917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each approach has its particular theoretical and practical merits and target audience. The programming language Sig has been designed to unify the underlying paradigms in a novel way. The natural expressivity of visual approaches is combined with the support for concise pattern-based symbolic computation of functional programming, and the rigorous, elementary semantical foundation of synchronous approaches. Here we demonstrate the current state of implementation of the Sig system by means of example programs that realize typical components of digital sound synthesis.","PeriodicalId":88474,"journal":{"name":"El Farmaceutico","volume":"33 13 1","pages":"35-36"},"PeriodicalIF":0.0,"publicationDate":"2014-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90150741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
