1 -qadam: simlarni ulash

Kerakli apparat

• A1: Arduino Uno
• U1: 3,5 mm audio raz'em

• R1: 150 ohmli rezistor

  yoki 140 ~ 160 ohm qarshilik (masalan, 100 + 47, 100 + 27 + 27)

• R2: 100 ohmli rezistor
• C1: 100 nF kondansatör
• Simlar

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

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)
