Arduino based MIDI Drum Sequencer
video upload by akestromer
"This sequencer started as a Big Button Sequencer. When I looked into building a drum sequencer without internal sounds his was the only one that made sense. So I owe a great deal of gratitude to Look mum no computer. I've since learned a great deal and added and removed a lot of code, out of the about 800 lines of code there are still a few in there that come from him.
I used an atmega328p, some 74HC595s, a 74HC14 and some other stuff.
In this program the sequence currently running is in a 2d array of booleans. But to save space they're saved in the dynamic(?) memory (and the eeprom) as bytes. 2 per sequence. The 16 sequences are 16 steps long and each have 12 tracks.
I'll try to post a simple version of the code soon. It's kind of a mess.
"Sketch uses 8174 bytes (25%) of program storage space. Maximum is 32256 bytes. Global variables use 1125 bytes (54%) of dynamic memory, leaving 923 bytes for local variables. Maximum is 2048 bytes."
Anyway, I hope this helps someone."
