Dear colleagues,

On the BP3 project ([https://bp3.tech](https://bp3.tech)) we are using the Csound 6.18 console in 3 environments: MacOS, Windows and Linux. No problem with MacOS and Linux, but in Linux our default orchestra file is rejected with an error  
“syntax error, unexpected STRING\_TOKEN (token “””)  
e[m from file …/csound\_resources/0-default.orc (1),e[m line 47"  
which points at the first “connect” instruction. Below is the faulty “0-default.orc” file. Can you explain this error and how to correct it for compatibility with all environments?  
I have already replaced all tabs with 4 spaces, as advised by ChatGPT 😉

; New Csound instruments for BP3’s default Csound score output.  
; They follow the specifications handled by BP3 version 3.0.0 and above.

; Instruments:  
; 1 Plucked string (outputs to StereoDelay)  
; 2 Plucked string (outputs to StereoChorus)  
; 3 Synth brass (outputs to GlobalReverb)  
; 10 Sine wave (outputs to GlobalReverb)  
;  
; Effects:  
; StereoDelay (outputs to GlobalReverb)  
; StereoChorus (outputs to GlobalReverb)  
; GlobalReverb (outputs to file/speakers)

; Default instrument parameters used by BP3:  
; p2 start time  
; p3 duration  
; p4 pitch in either octave point pitch-class or cps format  
;  
; Volume (range 0-127) is supplied by performance control \_volume() as  
; p5,p6 beginning & end volumes  
; p7 a table number containing the volume function (or 0)  
; When p7 is positive, the table is used instead of the beginning & end values  
;  
; Pitchbend is supplied in cents as  
; p8,p9 beginning & end pitchbend values  
; p10 a table number containing the pitchbend function (or 0)  
; When p10 is positive, the table is used instead of the beginning & end values

; This file looks best with a tab size = 4 spaces.

Hi!

You are using some non standard quotes ” Replace them with normal ASCII quotes "  
Linux is picky in such regard.

Hope it helps!

On this forum, the quotes look non-standard. However, I have checked the “orc” file and can see that the 160 quotes it contains are standard.
