PhatOne - New DIY Programmable Mono Rack Synth Based on AS33xx and Arduino
DIY Synthesizer - PhatOne Demo (AS33xx and Arduino based) Published on Apr 28, 2019 Krzychu1995
English description below
==========================
Mam przyjemność zaprezentować instrument PhatOne - monofoniczny, programowalny syntezator w formacie rack 19" 1U. Sterowanie odbywa się za pomocą kilku przycisków na panelu wraz z 2 enkoderami (konfiguracja, edycja presetów i ich zapis). Moduł zbudowany jest w oparciu o układy serii AS33xx firmy Alfa z Łotwy, w części cyfrowej znajdują się dwa układy ATmega 328P-PU zaprogramowane w środowisku Arduino (łącznie ok 2000 linii kodu). Zastosowanie mikrokontrolerów umożliwiło ponadto pozbycie się sprzętowych generatorów modulacji (ADSR i LFO), co znacząco wpłynęło na koszt instrumentu.
Parametry:
-2x 3340 VCO TRIANGLE, SAW, PULSE/SQUARE
-1X 3320 VCF (OPARTY NA OBWODZIE Z PROPHETA 5)
-2X ADSR (ZREALIZOWANE W SOFTWARE)
-2X LFO (ZREALIZOWANE W SOFTWARE)
-MATRYCA MODULACJI 4 SLOTY (SOFTWARE)
-MODULACJA FM VCO1 - VCO2
-128 MIEJSC W PAMIĘCI
==========================
I am pleased to present PhatOne instrument - monophonic, programmable synthesizer in rack 19" 1U format. For steering purposes there are several buttons on panel and 2 encoders (configuration, preset edit and saving). Module is basen on AS33xx IC produced by Alfa in Latvia, in digital part there are two ATmega328P-PU chips programmed in Arduino environment (around 2000 lines of code). Employment of microcontrollers made possible to get rid of hardware modulation sources (ADSR, LFO). Thanks to this costs are lower.
Parameters:
-2x 3340 VCO TRIANGLE, SAW, PULSE/SQUARE
-1X 3320 VCF (BASED ON PROPHET 5)
-2X ADSR (MADE IN SOFTWARE)
-2X LFO (MADE IN SOFTWARE)
-MODULATION MATRIX 4 SLOTS (SOFTWARE)
-FM MODULATION VCO1 - VCO2
-128 MEMORY LOCATIONS

"For the end of year - short demo of my DIY synth. It played bassline and lead. Rest of arrangement done on Arturia Minimoog and Microbrute."
