Well, I've been working for about 2 months now on an AY38910 based synth-step sequencer using an arduino.
Basically my goal was to learn a bit of arduino, learn electronics, have fun working on this and of course have my I-made-my-self-music-instrument a la carte, with all the buttons and leds I want, where I want, and that do exactly what I decide... or sort of .
The idea is to built a 6 voice (2xAY) 16-step sequencer synth, with midi support and lots of flashy leds weeeeeeeeeeeeeeee .
Last week I finished 2 boards with all the components to control the basic stuff of the step (buttons and leds) a mixer with op-amp and the control of the 2 AY, all of this controlled by an arduino mega.
this is the arduino wiki page I created with all kick start info how I controlled the PSGs
On my last uploaded vid I show what I currently have
The current working controls:
16 buttons step sequencer
6 buttons voice selector
6 volumen knobs for mixer
feats Ill be working on:
add rotary encoder with pushbutton for various functions (envelope changing, mode ostinato, arpegiator)
2 bit sub-step editor (for a total of 64 notes instead of 16)
program behaviour for loop launching mode (using the 16 step buttons)
add midi in for easy note input...
Well and any other thing ill come up ... still a lot of work in progress, but hey I its a good way to "waste" my time here . I hope to get some ideas/feedback from you or inspire others into a similar journey
