Re etsa synthesizer ka matsoho a rona

Lisebelisoa tse rekisoang mabenkeleng a khethehileng hangata li theko e boima haholo, 'me tse ngata tsa tsona li na le likarolo tse sa hlokeng bohle.

Haeba u batla ho boloka chelete 'me u rata lisebelisoa tsa elektronike, u ka leka ho iketsetsa ntlo maiketsetso ka matsoho a hao.

Mokhoa oa ho etsa synthesizer ka matsoho a hau

Ho na le merero e mengata ea tlhahiso motsoako oa synthesizer - ho tloha ho analoge e bonolo ho ea ho ea dijithale. Kajeno u tla ithuta ho etsa linotlolo tse 48 tsa polyphonic maiketsetso uena . Sesebelisoa, se tla tšohloa, se tla hahoa motheong oa 4060 CMOS logic chip. E tla u lumella ho bapala likhoele le lintlha ho 4 octave . Sena se ka finyelloa ka ho sebelisa lijenereithara tse 12 bakeng sa lithane tse 12 le lijenereithara tse 48 (e le 'ngoe bakeng sa linotlolo tse 48).
