Hi Csound

I'm trying to play a standard MIDI file using Csound, 

but found no ways to eliminate the clicks, which according to some tutorials are caused by missing envelope. However, after applying the opcode linenr and tweaking its arguments along with the i-time amplitude, I still hear the clicks. 

I had thought that maybe the durations of the notes vary and a single fixed envelope could fail to cover all of them. But no matter how small (like 0.01) the rise-time and decay-time I feed linenr, the clicks are still there.

Did I miss anything else?

My command for generating the output WAVE file from the MIDI:

csound -W -Fdeb_clai.mid -omidiout.wav midi.orc midi.sco

Here is my .orc, and .sco (the MIDI file that i was using is also attached): 

; midi.orc

sr = 44100

ksmps = 10

nchnls = 1

0dbfs = 1

instr 1 ; With envelope

ifrq cpsmidi

iamp ampmidi 0.5

kamp linenr iamp, .05, .5, .01 ; amp, riseTime, decTime, expDecFactor

a1 oscil iamp, ifrq, 1

out a1

endin

; midi.sco

f1 0 4096 10 1

f0 30

Thanks,

Beinan

You need to apply the envelope to your output by sending to the amp input of your oscillator:

instr 1 ; With envelope

ifrq cpsmidi

iamp ampmidi 0.5

kamp linenr iamp, .05, .5, .01 ; amp, riseTime, decTime, expDecFactor

a1 oscil kamp, ifrq, 1

out a1

endin

You were creating the envelope, but not using it :)

and if you want a really *beautiful* oscillator sound, use poscil
instead of oscil.
(this is a tip of luis jure, if i recall correctly ...)
