It can be used to facilitate recording to a mobile device, computer, DSLR camera, or connected directly to a PA system. The input and output connections are located on the top, bottom, left, and right panels, with the top panel reserved for controls and meters. The interface has four combination XLR/1/4-in input jacks. The first two double-up as Hi-Z instrument inputs and the second two can act as line inputs. Two further line inputs are available on a 1/8-in mini stereo jack input and RCA ports. There are microphone preamplifiers included on all four XLR inputs, with phantom power that can be switched on/off for pairs of channels. There is also a mini-jack input and output for MIDI. The interface has a stereo line output on 1/8-in mini jack port (unbalanced), and left and right XLR outputs (balanced). It also has a miniDIN connector for connecting to external devices. A number of cables are supplied with purchase: lightning to mini-DIN, USB-C to mini-DIN, and USB-A to mini-DIN.

Because of its complexity, computer-aided orchestration remains a partially unsolved problem and several systems have been developed in the last twenty years. This article presents a practical overview of the recently introduced Orchidea framework for dynamic computer-aided target-based orchestration. Orchidea continues the line of tools dedicated to the subject (the so-called Orchid* family) originally developed at the Institut de Recherche et Coordination Acoustique/Musique in Paris. Unlike its predecessors, Orchidea uses a combination of optimization techniques that include stochastic matching pursuit, long short-term memory neural networks, and monoobjective evolutionary optimization, with a specifically designed cost function. Symbolic constraints can be integrated in the cost function, and temporally evolving sounds are handled by segmenting them into a set of static targets optimized jointly and then connected. Orchidea is deployed in three different ways: a standalone application, designed to streamline a simplified compositional workflow; a Max package, targeted at composers willing to connect target-based orchestration to the more general area of computer-aided composition; and a set of command-line tools, mostly intended for research purposes and batch processing. The main aim of this article is to present an overview of such software systems and show several instances of the Orchidea framework's application in recent musical productions, tracing the path for future research on the subject.","PeriodicalId":50639,"journal":{"name":"Computer Music Journal","volume":"45 4","pages":"40-56"},"PeriodicalIF":0.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43407719","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}

A major criterion was to understand “music studios” as cultural territories, as places for creation, collaboration, and exchange. We present a timeline highlighting the main trajectories of composers, institutions, and events, all related to the development of these studios. We interviewed composers and investigated a wide variety of documents, ranging from scholarly papers and journal articles through books, recordings, and websites. As a result, the timeline introduces the main spaces that have fostered electroacoustic music in Brazil, revealing the idea of gambiarra [make do, workaround], a sort of Brazilian DIY culture.","PeriodicalId":50639,"journal":{"name":"Computer Music Journal","volume":"46 1-2","pages":"94-107"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64509532","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}

To this end, the text discusses the notion of cultural anthropophagy, as formulated by Oswald de Andrade; discusses a brief history of the first initiatives in the field of electroacoustic music in Brazil; and focuses on the historical importance and the particularity of the Studio PANaroma, which substantially changed the development of electroacoustic music in the country.

Support for artistic activities has usually been postponed to solve urgent social problems. Despite that, the development in these countries of the electronic arts, in general, and electroacoustic and computer music, in particular, is astounding. Mauricio Kagel, Reginaldo Carvalho, Hilda Dianda, Juan Amenabar, Horacio Vaggione, Jorge Antunes, Jocy de Oliveira, José Vicente Asuar, and Juan Blanco are only some of the many names in the ocean of electroacoustic music creativity that has always been Latin America. Archiving and disseminating electronic art—and working on a revised version of its history—is crucial to comprehend the present and build our future. The Latin American Electroacoustic Music Collection, hosted by the Daniel Langlois Foundation for Art, Science, and Technology in Montreal, has over 1,700 digital recordings of compositions created between 1957 and 2007 by almost 400 composers. The Collection has recovered and made visible (and listenable) the creative work of many composers otherwise almost forgotten. It has defied the hegemony of the computer and electroacoustic music history narrative, helping to break barriers and widening the way their history is understood.","PeriodicalId":50639,"journal":{"name":"Computer Music Journal","volume":"46 1-2","pages":"8-24"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46664622","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}

Lumínico's proposal offers, as sound and audiovisual artists, an alternative to the experience of the traditional chamber music and electroacoustic concert, both to themselves and to the audience. In the field of music, it blurs the binary distinction between artistic work and audience by transferring the creation of the uninterrupted concert to the very moment of its execution and reception. This way, a Lumínico concert generates a unique, unrepeatable, and ephemeral event that emerges thanks to the characteristics of the scenic realization, starring the ensemble members and the audience.","PeriodicalId":50639,"journal":{"name":"Computer Music Journal","volume":"46 1-2","pages":"72-81"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45872595","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}
