It translates the gestures of a performer to the standard communication protocol of MIDI, allowing for flexible mappings of performance data to sonic parameters. When used in conjunction with a realtime signal processing environment, the Accordiatron becomes an expressive, versatile musical instrument. A combination of sensory outputs providing both discrete and continuous data gives the subtle expressiveness and control necessary for interactive music.","authors_text":"Michael Gurevich, Stephan von Muehlen","cross_cats":["cs.SD","eess.AS"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.HC","submitted_at":"2020-10-04T12:57:08Z","title":"The Accordiatron: A MIDI Controller For Interactive Music"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2010.01574","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9ef6dffb9a58fb2497458ae217271ca8126a8e561e0d12e69cb4255f675187fa","target":"record","created_at":"2026-07-05T01:40:06Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c7aedd90aae8b7b7aa988b408d6db3e3abda429f45fc9a13a059b2df82a6d452","cross_cats_sorted":["cs.SD","eess.AS"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.HC","submitted_at":"2020-10-04T12:57:08Z","title_canon_sha256":"e1914703c973b9e3b24b7d5d62167dc5a4389e0d4c66806c0c0e21e866294d72"},"schema_version":"1.0","source":{"id":"2010.01574","kind":"arxiv","version":1}},"canonical_sha256":"6ba901126131c86ba0dfeb0ba89f0dedf93c923b067e4f1959e967792a49decd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6ba901126131c86ba0dfeb0ba89f0dedf93c923b067e4f1959e967792a49decd","first_computed_at":"2026-07-05T01:40:06.986011Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:40:06.986011Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"J1YTF++qMVKS4GzRr6NhCIWxJ5sqeUGV/u4QyC7P5HW6KNvi4AJmL9PnwsF0oFDKCkabbM5nPmAhplBZiBkwCw==","signature_status":"signed_v1","signed_at":"2026-07-05T01:40:06.986364Z","signed_message":"canonical_sha256_bytes"},"source_id":"2010.01574","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9ef6dffb9a58fb2497458ae217271ca8126a8e561e0d12e69cb4255f675187fa","sha256:f53f1d30d2c32bafa177a3cf884ee964038162dc9031efe3586bc260fab6d15c"],"state_sha256":"90cddfc1ab7139afc8b0c989552fb3d073cda47a79456db534e675e526b927e2"}
