midipiano_chung Files

midipiano_chung a program by NGUYEN.Chung (freeware 2012-2017)


brainpiano_chung version with neural network brain autochord (freeware 2017)

brainpiano2_chung version with custom neural network brainSONG music generator (freeware 2017)

note: you can save brainchord as FANN .dat training file to use with FANNtool to create a FANN .net neural network file
if the file "brainsave/mybrain.net" is found then this FANN network will be loaded as brainchord instead by brainpiano2_chung
 
  

to install, just unzip the zip file to c:/midipiano_chung folder

to uninstall , just delete unzipped folder


to run, double click on midipiano_chung.exe  or   brainpiano_chung.exe


you must have at least one midiinput port installed in your system.

the program takes the first selected one.



you can make multiple copies in different folders and rename midipiano_chung.exe program.



to connect to a midiplayer , you can install a program like "maple" the free version gives
you 4 out/in midi ports.

chooze the output of your midiplayer to "maple out1 port",and if midipiano is connected to 
"maple in1 port" , it will sound as midi data is played.


you can select the midi out port with a midiplayer like "midi_chung" you can find there

velocity curves (V key):

  velo0 => linear
  velo1 => curve1
  velo2 => curve2 -> preferred
  velo3 => curve3

automod (V key) : 0...100% automodulation rate

attack/decay (V key) : (A key)on/off


delay : you can add delay on noteoff (notes got longer) by 50...1000 ms
speed : sound speed (50..200)%

  leftmouse button  => point
  rightmouse button => line

  up to 200 undo/redo 


you can add your own user sounds ( i=10 to 14 ), they will be detected automatically.
add wav files "piano"+str(i)+"_"+str(octave)+".wav"  or .mp3 
octave=12,24,36,48,60,72,84,96,108  (60=middle C)

for example for i=9 add piano9_12.wav, piano9_24.wav, ..., piano9_108.wav   or .mp3
to the ./sounds/ folder.

use wav 16bits 44100Hz stereo  /  or mp3
