i was testing with simple sketch for synth to make monophonic synth using this sketch
from above code i playing keyboard with serial communication. getting succesfully note_on on Particular key press & Note_off on Key release.
first ... please check below
am I using correct code in "void loop() " for Note_on & Note_off event ????
Because i am feeling a little latency in Fast fingering.
if No , Please describe here correct way...
and Second Main thing to ask:---
please try to understand what i want to ask. I do not know what word is used for event of synth process inwhich " in mono mode , if any new key is released after holded a old key , old key should begin sound.
i want my synth behave like below.
for example in sequence :- suppose : [Note1 for Key1 , Note2 for Key2 , Note3 for Key3
step1:- i press and hold key1 >>Note1 will sound on ,
step2:- i press and hold key2 without release key 1 >>> Note1 will sound off and Note2 will sound on.
step3:-i press and hold key3 without release Key1 & Key2 >> Note2 will sound off Note3 will sound on.
step4:-now if i will release Key3 without release Key1 & Key2 >> Note3 will sound off and Note2 should be sound on.because of key2 was holded before presses key3
step5:- now if i will release Key2 without release key1 >>> Note1 should be sound on because of already hold of Key1
just like Professional Synthesizor Keyboard in Mono Mode Patches.
I am sorry i you did not understand my wording.
if anyone my senior understand above event of NoteOn/NoteOFF, please describe How to write it in code
