Umarnin Amfani da samfur

1. Haɗa PICO MIDI SysEx Patcher tsakanin mai sarrafa ku da vintage synthesizer da kake son ƙirƙirar faci don.
2. Kunna mai sarrafawa da vintage synthesizer.
3. Yi amfani da maƙallan rotary guda biyu don kewayawa da canza sigogi a cikin ainihin lokacin yayin kunna jeri.
4. Yi amfani da maɓallin turawa don canja wurin duk wani saƙon MIDI daga babban mai sarrafa zuwa synth manufa.
5. Koma zuwa littafin mai amfani don ƙarin cikakkun bayanai kan yadda ake amfani da nuni da yadda ake haɗa sigogi a matakin software.
   Lura: Tabbatar cewa vin kutage synth yana samun goyan bayan PICO MIDI SysEx Patcher kafin amfani da shi. Hakanan, koma zuwa sashin bayanin kayan masarufi na littafin mai amfani don bayani akan abubuwan da ake buƙata da yadda ake haɗa su.

GAME DA KYAUTA

• Ina da wuri mai laushi don vintage synthesizers. Yanayin samar da kiɗan na yanzu yana da ban sha'awa, kar a same ni ba daidai ba, amma ni kaina na fi yin wasa da maɓallan madannai na “marasa amfani”.
• Ɗayan koma baya tare da kayan aiki daga tsakiyar 80's shine wani lokacin rashin shirye-shirye. Shirye-shiryen wasu daga cikinsu na iya zama m, kuma gaskiyar cewa software na ɓangare na uku sau da yawa ba sa goyon bayan yarjejeniyar SysEx ba ta taimaka ba.
• Akwai hanyoyi guda biyu don fuskantar wannan matsala ta wata hanya: software (wanda ya ce Ctrlr?) da hardware.
• Ba lallai ba ne a faɗi, muna ma'amala da maganin kayan masarufi anan.
• Ina da (Ina tsammanin) ya riga ya haɓaka shirye-shiryen wasu kayan aiki masu mahimmanci daga zamanin zinare kamar Roland a-Juno, Oberheim Matrix 6, Korg DW8000, SCI Multitrack da sauransu tare da mai shirya shirye-shiryen SysEx da masu tsarawa bisa arduino MEGA. Abin da na yi kwanan nan ga hukumar microcontroller Rasberi Pi Pico ya sa na yi tunanin baya kan yadda zan magance matsalar.
• Rasberi Pi Pico mai arha ne kuma mai ƙarfi microcontroller kuma zaɓi ne na fi so, kwanan nan. Ina amfani da shi don sababbin ayyuka, amma kuma don sake duba wani tsohon aikina.
• Tare da iyakokin ƙwaƙwalwar ajiya na IC sun ɓace (amma iyakataccen adadin GPIOs) Na ƙare tare da wani abu tare da keɓancewa daban-daban da aiki: ow dangane da aikin da ya gabata.
