Boredom hit again, so last weekend i knocked up this, a basic duophonic synth 64 step sequencer
Built on the fly no diagrams, just used data sheets for IC pin locations.
It really is mad what one can do when boredom hits.
Duophonic playing two note's/Voices at same time.
one up from Monophonic = playing single note/voice
and not Polyphonic = playing three or more note's/Voices at same time
STM32F407, programmed within the Arduino IDE,
with 2 Sinple R-2R ladder DAC's, using 8bit shift register,
8x8 led matrix module,
tm1638 7seq display with 8 buttons
128x64 lcd.
Rotary encoder switch
My two basic 8bit DAC sound card's
My taty build
and here is a silly demo, of the old skool 8bit sounds, running through a 64 step sequence
