Diy midi controller, Loop Daft Punk - Harder Better FASTEST Stronger


YouTube via Jimmy333x2
"one of the first test about midi loop.
I'm playing a midi base on cubase in a loop, it's not the same as the original one...
it's just to show recently added functions, as improved ADSR, Filters, delay...

at least my project has reached a better structure, now I can develop new features in a easier way.

New features:
startup memory control(EEPROM) just 2 blocks: 256kb , up to 1MB
Nokia(3310) display BMP images available.
more analog input enabled (3 MUX-8channel =24 IN) [it reamains just the last one to solder for 32 total IN]
Encoder enabled for menu selection.

Nowadays works:
complete menu implementation,
dual encoder
memory mapping for Sequences , BMP, Presets, other kinds of file..."

MIDI controller box (step 1)

"Underlying the project is a PIC18F452, I programmed using the CCS C compiler for PIC
Starting from a crystal oscillator and having from 10MHz internal PLL enabled (which multiplies the frequency x4) CIP process the code at a frequency of 40MHz, providing excellent uptime.
In the code I used for dynamic allocations, readings via analog MUX, management of double alphanumeric LCD display and LCD display (that of the Nokia 3310)

midibox receives the keys pressed on the keyboard via MIDI (note.on and note.off) and saves them on a buffer-based software dynamic lists.
the buffer is read and emptied at each interrupt caused by Timer1.
Meanwhile, the analog port multiplexers read and scroll through the various slider (16 hours), each of them has an associated MIDI Control Change command.
displays the values associated with each slider, the middle displays the bar charts."
