Hello everyone,

(my first question here, hopefully to the right address.. :D )

I have Csound 6.06 now installed to my 32-bit Ubuntu Studio laptop pc, and although I get sound from some Csound files, others produce no sound (but the GUI appears).  The only possible error I seem to get is this:

csound MonoPolySynthII.csd
virtual_keyboard real time MIDI plugin for Csound
WARNING: STK opodes not available: define environment variable RAWWAVE_PATH
(points to rawwaves directory) to use STK opcodes.

However, the audio-less Csound file doesn't require the stk opcodes.

Any suggestions appreciated! :)

Thanks!

brian

That is just an ignorable warning -- so ignore it!

Can we see an example that fails with fukl output?

It's a warning, just ignore it.

Hi guys,

thanks, I'll ignore it.

On another note, Mr. McCurdy made a very nice synth for me (attached here with a preset file to save presets), really powerful. However, I still get distorted "garbling" if I lengthen the filter and amp release times and play lots of notes. My hunch is that it's taking up lots of CPU (I see it in the cpu graph too).  --Is there a way to limit polyphony?  Perhaps in the CsOptions area?

I found the command "cpuprc". Perhaps this will work..?   What I'm looking for is a first-in-first-out polyphony limiter for realtime midi note input control.

hi -

you can limit the maximum number of instrument instances with maxalloc:
   maxalloc 2, 10
would only allow ten instances at the same time for instr 2.

Hi again!

ok, I tried maxalloc to 4 notes of polyphony for instruments 3 and 4 (polyphonic selector in GUI) and I still get the distortion if I lengthen amp and filter release and play a few notes fast. (audio demo included here)

It's as though my pc can't process all the data of the notes going in. (my pc isn't very old!)

I'll check back tomorrow!

Hi Brian,

For FIFO, I posted some demo code a while back on the old user's list.
You can find it here:

http://csound.1045644.n5.nabble.com/Realtime-midi-audio-and-polyphony-td1099266.html#a1099273

It's using a bit of an older coding style (it was pre-Csound6 times),
but could be useful as a starting point.

Hi Iain,

thanks for your tireless support! And I agree that FIFO is the best solution, rather than simply limiting notes. Hardware synths back the 80s had a fifo scheme, and I *think* that the oldest notes, when replaced, were cut off entirely. This makes sense, in fact, because if you play, let's say, a trill of C and D back and forth, just as a regular piano, the new note completely replaces the old note. Otherwise there would be a build-up of old-note releases. And I think this is precisely what is building up in this case, and causing an "oversignal" and therefore, garbling.

maxalloc will just prevent new notes from starting. I think that in RT performance it is more useful to stop the oldest notes whilst allowing them to complete there release stages thus preventing clicks. This is still pretty easy to implement:

-odac -M0 -+rtmidi=virtual

sr      =       44100  

ksmps   =       8

0dbfs   =       1

gkactive init 0         ; counts number of notes

giPolyLim init 2        ; polyphony limit

instr   1

 if active:k(p1,0,1)>giPolyLim then ; if poly limit exceeded...

  turnoff

 endif

 

 aSig   poscil  linsegr(0.1,0.3,0),cpsmidi()

        outs    aSig,aSig

endin

The distortion evident in your ogg is indeed caused by buffer under-running but it seems that something is eating up inordinate amounts of CPU when notes are released, maybe an '-r' opcode, perhaps transegr. I think that pinpointing this will solve the problem better than limiting polyphony - but a polyphony control is probably not a bad thing. I'll investigate these things and report back.

Iain
