	FWIW, I've tested this issue with Sugar 0.88 (SoaS Mirabelle - more recent) and gotten identical results. I also substituted this last line: def choose(self, widget): chooser = ObjectChooser(self, what_filter=mime.GENERIC_TYPE_AUDIO) result = chooser.run() if result == gtk.RESPONSE_ACCEPT: jobject = chooser.get_selected_object() if jobject and jobject.file_path: filename1 = jobject.file_path print 'FileName = ', filename1 self.w.set_filechannel("filename1", filename1) set_filechannel is a method from csndsugui; it too returns identical results. I wonder if I need to find some other way of passing a filename to Csound? (Are there any other options?)

Subject	Re: [Cs-dev] Fw: Csound API Question?
	I tested here now, just to make sure, and string channels work fine. I have had trouble with string channels sometime during the last year, but now it seems all ok. Sorry for the noise there. An alternative way to send Csound a string (Art) is by using a string p-field in a score statement. best Oeyvind 2010/10/12 Art Hunkins : > FWIW, I've tested this issue with Sugar 0.88 (SoaS Mirabelle - more recent) > and gotten identical results. > > I also substituted this last line: > def choose(self, widget): > chooser = ObjectChooser(self, what_filter=mime.GENERIC_TYPE_AUDIO) > result = chooser.run() > if result == gtk.RESPONSE_ACCEPT: > jobject = chooser.get_selected_object() > if jobject and jobject.file_path: > filename1 = jobject.file_path > print 'FileName = ', filename1 > self.w.set_filechannel("filename1", filename1) > > set_filechannel is a method from csndsugui; it too returns identical > results. > > I wonder if I need to find some other way of passing a filename to Csound? > (Are there any other options?) > > Art Hunkins > > > ----- Original Message ----- > From: "Victor Lazzarini" > To: "Developer discussions" > Sent: Monday, October 11, 2010 5:11 AM > Subject: Re: [Cs-dev] Fw: Csound API Question? > > >>I have tested the string channels in the latest Csound and there is >> nothing wrong with them.

Subject	Re: [Cs-dev] Fw: Csound API Question?
	another idea would be to use the --strset option, for instance: --strset1=/Users/jh/Desktop/Ganze4_96k.aiff instr 1 Sfile strget 1 aout diskin2 Sfile, 1 out aout endin i 1 0 5 i found this useful in several situations. unfortunately it is not possible to write --strset1="/Users/jh/Desktop/Ganze4_96k.aiff", so it is necessary to have a file path without spaces. joachim Am 12.10.2010 um 08:46 schrieb Oeyvind Brandtsegg: > I tested here now, just to make sure, and string channels work fine. > I have had trouble with string channels sometime during the last year, > but now it seems all ok. > Sorry for the noise there. > > An alternative way to send Csound a string (Art) is by using a string > p-field in a score statement. > > best > Oeyvind > > > 2010/10/12 Art Hunkins : >> FWIW, I've tested this issue with Sugar 0.88 (SoaS Mirabelle - more >> recent) >> and gotten identical results. >> >> I also substituted this last line: >> def choose(self, widget): >> chooser = ObjectChooser(self, what_filter=mime.GENERIC_TYPE_AUDIO) >> result = chooser.run() >> if result == gtk.RESPONSE_ACCEPT: >> jobject = chooser.get_selected_object() >> if jobject and jobject.file_path: >> filename1 = jobject.file_path >> print 'FileName = ', filename1 >> self.w.set_filechannel("filename1", filename1) >> >> set_filechannel is a method from csndsugui; it too returns identical >> results. >> >> I wonder if I need to find some other way of passing a filename to >> Csound? >> (Are there any other options?) >> >> Art Hunkins >> >> >> ----- Original Message ----- >> From: "Victor Lazzarini" >> To: "Developer discussions" >> Sent: Monday, October 11, 2010 5:11 AM >> Subject: Re: [Cs-dev] Fw: Csound API Question? >> >> >>> I have tested the string channels in the latest Csound and there is >>> nothing wrong with them.
