Musansävellysohjelma

Post by DJ-Filbe »

Tällainen olisi projektina. Eli kirjoitat biisin nimen ja ohjelma säveltää "kauniin" kappaleen MD5-hashin perusteella (ideaa ei ole lainattu Ohjelmointiputkan kisasta :roll: ). Ohjelmaan lisään bassokuviot, rummut ja lisää sointukuvioita. Nyt tuo kuulostaa kököltä, koska rytmi katoaa, käytetään siniaaltoa jne...
Siitä se lähtee. Jos joku haluaa mukaan tekemään, voi laittaa YV:tä (mutta tunnetusti diizei nöödin projektit kaatuvat, joten älä ihmeessä tule "tiimiin" mukaan).

Ihan mielenkiintoinen idea, vaikkei tämä yllä useimpien putkassa julkaistujen tasolle. Biisissä voisi olla enemmänkin järkeä kuin vain randomit piippaukset. Ainakin soinnut olisi hyvä lisä ja jonkinsortin vaihtelua tuohon rumpu joka iskulla-systeemiin. Ei tätä vielä ilokseen kuuntele :d
Niin ja semmoinen vielä, miksi tuo koodi pitää olla kahdessa osassa?
Jos tämä viesti on kirjoitettu alle 5 min. sitten, päivitä sivu. Se on saattanut jo muuttua :roll:

Piippaukset eivät ole täysin randomeita - sointukuvioita on ennalta määritelty. Tosin ne eivät ole täysin yhteensopivia keskenään :D
Soinnut paljastuvat kun lisään basson - ominaisuus on jo valmis ja tuossa yötä vasten ajattelinkin laittaa sen version tänne.
Rummut? No joo. Sinifunktio kusee kun vaihdetaan nuottia, se hyppää monta arvoa alaspäin :/ tähän olisi kiva saada helppiä.

Tulossa kanttiaalto, saha-aalto ja yhdistelmäaaltoja, sekä bassoääni taustalle. Julkaisen enemmän sitten kun on ainakin kolme kertaa enemmän näytettävää :D

Päivitystä. Jonkinlainen metronomi, muutama äänivaihtoehto ja yksinkertainen basso taustalle.
