send comments and flames to @hugocristo


build 0004: 26oct 2011 - alpha version

almost ready to use. features:
+ play / edit mode (bt 1)
+ note load / save (bt 2 on edit mode)
+ note edit (potentiometer ranging from 21 to 108)
+ midi program change (bt 2 on play mode)
+ steps navigation left / right (bt 3/4)

there are some glitches caused by the breadboard, mainly push button debounces. i've started using two libraries: bounce and arduino midi lib for better event handling.

todo: finish case layout, add more tracks and start coding the pc midi editor in processing.


build 0003: 22oct 2011 - controlling a korg ag10 synth module

i've found very useful information about midi programming here and here. the sequencer has been rebuilt from scratch and now it features a led indicating playing/stopped modes and a push button to change current midi program (0-127).

i'm designing a case and a few panel layouts to make this easy to connect to other midi devices. more on this later...

a few pics of the third build are available on my flickr page.


build 0002: 16oct 2011 - arpeggiator + random sequence

added a software-generated arpeggio and editing capabilities. push button #1 enters edit mode. push button #2 changes current note frequency from B0 to D#8.

todo: add push button #3 to decrease current note frequency.


playing and editing some random sequences.


build 0001: 16oct 2011

lcd + piezo tone generator working.
