2 -qadam: dasturiy ta'minotni o'rnatish

  1. Manba kodini yuklab oling va uni chiqarib oling.

    Https://github.com/risgk/digital-synth-vra8-p/tree/vra8-px-v2 saytidan

  2. Tuksiz MIDISerial ko'prigini yuklab oling va uni chiqarib oling.

    Http://projectgus.github.io/hairless-midiserial/ saytidan

  3. LoopMIDI -ni yuklab oling va o'rnating.

    Http://www.tobias-erichsen.de/software/loopmidi.html saytidan

3 -qadam: Sintezatorni ishga tushiring

Sintezatorni ishga tushiring

Windows uchun tushuntirish

  1. DigitalSynthVRA8Px.ino -ni Arduino Uno -ga yozing va Arduino IDE -dan chiqing.

    Diqqat: Arduino IDE 1.8.1 yoki undan keyingi versiyasidan foydalaning

  2. LoopMIDI -ni ishga tushiring.

  3. Sochsiz-midiserial.exe dasturini ishga tushiring (Tuksiz MIDISerial ko'prigi).

    • [Fayl]> [Tanlovlar]> [Baud tezligi] ni 38400 bps ga o'rnating.
    • Seriya portida Arduino Uno (COM*) -ni tanlang.
    • MIDI In -da loopMIDI portini tanlang.

  4. Google Chrome bilan vra8-px-ctrl.html (VRA8-Px CTRL) ni oching.

    • MIDI OUT -da loopMIDI portini tanlang.
    • MIDI IN -da MIDI boshqaruvchisini tanlang (agar u bo'lsa).
  5. Dastur klaviaturasini bosing (yoki bosing) va siz ovozni eshitasiz.

OGOHLANTIRISH

  • Ovozni kuchaytirgichga/karnayga ulaganingizda yoki taxtani qayta o'rnatganingizda, bosish tovushlari paydo bo'lishi mumkin
  • Tekshirish moslamalarini o'zgartirganda (ayniqsa AMP EG va FILTER CUTOFF) bosish tovushlari paydo bo'lishi mumkin.
  • FILTER RESOsi past bo'lgan FILTRE CUTOFF karnaylarga zarar etkazishi mumkin

  • Arduino PWM audio chiqishi bir qutbli LINE OUT

    Iltimos, buni quvvat kuchaytirgichiga/naushnik kuchaytirgichiga ulang (to'g'ridan -to'g'ri karnayga/naushnikga emas)
