	Hello, I am trying to port a group of applications (the Sugar TamTam activities) to csound 6 using the python bindings. This is needed because csound 5 is not longer supported in new Linux distributions (Fedora > 20, and new versions of Ubuntu). I am trying to do all the port using python, the old version used a c wrapper but was complicated distribute in environments with different architectures. I can make the basic examples work (from [1] and [2]) but I couldn't find a way to use the instruments data files in Tamtam work. I created a minimal test case, are 3 files that can be downloaded from http://dev.laptop.org/~gonzalo/csound/ When I run it on Fedora 21, I get: $ python csound6_test.py 0dBFS level = 32768.0 Csound version 6.03.2 (double samples) Sep 30 2014 libsndfile-1.0.25 rtaudio: ALSA module enabled rtmidi: ALSA Raw MIDI module enabled --Csound version 6.03.2 (double samples) Sep 30 2014 graphics suppressed, ascii substituted 0dBFS level = 32768.0 orch now loaded audio buffered in 256 sample-frame blocks ALSA output: total buffer size: 1024, period size: 256 writing 256 sample blks of 64-bit floats to dac SECTION 1: ERROR:root:load_instrument message "f5001 0 0 -1 /home/gonzalo/sugar-devel/honey/musickeyboard/music-keyboard-activity/test/piano 0 0 0" Traceback (most recent call last): File "csound6_test.py", line 47, in <module> c.load_instrument('piano') File "csound6_test.py", line 39, in load_instrument self.perf.inputMessage(message) File "/usr/lib64/python2.7/site-packages/csnd6.py", line 3036, in <lambda> __getattr__ = lambda self, name: _swig_getattr(self, CsoundPerformanceThread, name) File "/usr/lib64/python2.7/site-packages/csnd6.py", line 57, in _swig_getattr raise AttributeError(name) AttributeError: inputMessage inactive allocs returned to freespace end of score. overall amps: 0.0 overall samples out of range: 0 0 errors in performance Csound tidy up: Segmentation fault On Fedora 22 is a little different but crash anyway: $ python csound6_test.py 0dBFS level = 32768.0 Csound version 6.03.2 (double samples) Jan 27 2015 libsndfile-1.0.25 UnifiedCSD: /home/gonzalo/sugar-devel/honey/musickeyboard/music-keyboard-activity/test/tamtamorc.csd STARTING FILE Creating options Creating orchestra Creating score rtaudio: ALSA module enabled rtmidi: ALSA Raw MIDI module enabled sorting score ... ... done --Csound version 6.03.2 (double samples) Jan 27 2015 displays suppressed 0dBFS level = 32768.0 orch now loaded audio buffered in 256 sample-frame blocks writing 512 sample blks of 64-bit floats to dac ERROR:root:load_instrument message "f5000 0 0 -1 "piano" 0 0 0" Traceback (most recent call last): File "csound6_test.py", line 52, in <module> c.load_instrument('piano') File "csound6_test.py", line 37, in load_instrument self.cs.inputMessage(message) File "/usr/lib64/python2.7/site-packages/csnd6.py", line 1915, in <lambda> __getattr__ = lambda self, name: _swig_getattr(self, Csound, name) File "/usr/lib64/python2.7/site-packages/csnd6.py", line 57, in _swig_getattr raise AttributeError(name) AttributeError: inputMessage removed instance of instr 0 inactive allocs returned to freespace end of score. overall amps: 0.0 0.0 overall samples out of range: 0 0 0 errors in performance 0 512 sample blks of 64-bit floats written to dac signalflowgraph: csoundModuleDestroy(0x155c910) Any help is welcomed, I am stuck :/ Thanks in advance, [1] https://github.com/csound/csound [2] https://github.com/csound/csoundAPI_examples -- Gonzalo Odiard SugarLabs - Software for children learning

	There is a logging.error() that seems to be printing the ERROR message. I think the method is InputMessage and that is why the Attribute Error is raised. Capital "I" .

	Thanks! I fix that and other error I found (and uploaded a fixed version) and now do not have errors but no audio is played. I use InputMessage() to play the instrument too. My code do SetOption('-odac') and I have tested doing that with the examples in csound_API_examples and the output go to the audio device without problems. I also tried do not load the csd file at all, but the result is the same.

	Possibly to do with the realtime audio module? Which one do you use? alsa, portaudio, jack, pulseaudio? Csound messages should indicate which.

	Hi, IIRC, the c code in TamTam was there to bypass the audio driver and talk directly to the soundcard... That was the only way to get decent performance out of the system! Maybe that can be removed now... Olivier On Wed, Jun 10, 2015 at 5:06 PM, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote: Possibly to do with the realtime audio module?

	How should I use it in a context where I need interaction with the user: * The user can select a instrument * The user play keys (in the physical keyboard in the computer or in a keyboard draw in the screen) and the notes are played. That is my final objective. I don't know if is relevant, but the application is using Gtk.

	I'm very happy to hear that things are being updated for the XO. I think there is great potential now to use som of the new features in Csound6 like dynamic instrument definitions, which could greatly simplify things (and allow more complex and interesting things). Also I think that performance should be sufficient using the perfThread and alsa output (as you can do in the Raspberri Pi). I'd be happy to test things out on my XO-1 if you let me know how I can try these latest things.

Attachments	None None
	Thanks Andres! I should say I am deeply ignorant about csound in general, and new features in particular. The csound part on the TamTam activities was like a black box for us. But I developed a piano activity using that black box, to make use of the touch screen in the last XO models (XO-4) You can try the activity here: http://activities.sugarlabs.org/en-US/sugar/addon/4654 Moving forward, csound 5 is not longer included in modern linux distributions, then I need start the many times postponed port to csound6. That is the reason I am trying to understand what is needed to play a note, with a instrument in csound 6. Gonzalo On Wed, Jun 10, 2015 at 7:09 PM, Andres Cabrera <mantaraya36@gmail.com> wrote: I'm very happy to hear that things are being updated for the XO. I think there is great potential now to use som of the new features in Csound6 like dynamic instrument definitions, which could greatly simplify things (and allow more complex and interesting things). Also I think that performance should be sufficient using the perfThread and alsa output (as you can do in the Raspberri Pi). I'd be happy to test things out on my XO-1 if you let me know how I can try these latest things.

	I'd be happy to test it out me too! I really think the problem is with bad calls to the API or with the audio driver. Csound5 csd files should run as is with Csound6.

	No. I have tried adding f0 36000 to the CsScore section of the CSD file. I also tried remove all and make the csd file only: <CsoundSynthesizer> <CsScore> f0 36000 </CsScore> </CsoundSynthesizer>. but do not change the result. I was looking for python examples for my use case, but didn't found nothing yet.

	I try to load one using InputMessage("F5000 0 0 -1 filename 0 0 0") The filename is piano and that file is http://dev.laptop.org/~gonzalo/csound/piano the same instrument file used in csound5 The original csd file is huge http://dev.laptop.org/~gonzalo/csound/tamtamorc.csd I don't know what is really needed and what not, then I am testing with different parts.

	yes, but that is just a table containing the piano waveform. You actually need an instrument to play it. Maybe you can have a quick scan of the Csound FLOSS manual to have an idea of what you need. If you google it, you'll get the address.

Subject	Re: [Cs-dev] Porting python program from csound 5.2 to csound 6
Attachments	None None
	Some improvements: I mixed the example from the f command http://www.csounds.com/manualOLPC/GEN01.html with a example using python to play a sound pressing a button https://github.com/csound/csoundAPI_examples/blob/master/python/example11.py And implemented it using Gtk instead of Tk (needs download the audio file http://www.csounds.com/manualOLPC/examples/beats.wav) from gi.repository import Gtk import csnd6 orc = """ sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 kamp = 30000 kcps = 1 ifn = 1 ibas = 1 ; Play the audio sample stored in Table #1. a1 loscil kamp, kcps, ifn, ibas out a1 endin""" c = csnd6.Csound() c.SetOption("-odac") c.CompileOrc(orc) c.Start() c.InputMessage('f 1 0 131072 1 "beats.wav" 0 4 0') perfThread = csnd6.CsoundPerformanceThread(c) perfThread.Play() def clicked_cb(button, perf): perf.InputMessage("i 1 0 2") win = Gtk.Window() btn = Gtk.Button('Play') btn.connect('clicked', clicked_cb, perfThread) win.add(btn) win.show_all() win.connect("destroy", Gtk.main_quit) Gtk.main() This works. If is useful for others I can send a pull request to add it to the examples.

Maybe you can have a quick scan of the Csound FLOSS manual to have an idea of what you need. If you google it, you'll get the address.
