Subject	[Csnd] Best way to send Table values over OSC
	Hi, I am using Csound with Quartz Composer, I am linking the programs using OSC. I was just wondering if there is an easier way of sending a large amount of table values in one OSC message. I am aware that you can use the table opcode to read values and assign them variables that are passed to an OSCSend, but is there a better way of doing this with large tables? Thanks Ed

	Can you print the values of a table to a string? If so yes it should work.

	After some playing around I came up with something that works but not for very long, the OSC stops sending after a few seconds and if I try to restart QuteCsound it crashes. <CsoundSynthesizer> <CsOptions> </CsOptions> <CsInstruments> sr = 44100 ksmps = 128 nchnls = 2 0dbfs = 1 #define Tables #2# #define Widgets #3# instr Init, 1 turnon $Tables turnon $Widgets gk_Slider1 init 0 endin instr Tables, 2 gi_TableSize = 16 gi_WriteTable ftgen 100, 0, gi_TableSize, 7, 1, gi_TableSize, gi_TableSize gi_ExponentialTable ftgen 101, 0, gi_TableSize, 5, 1, 0, 0.0001, 0, 1, 16, 0.001 endin instr Widgets, 3 kvalue invalue "slider1" if kvalue != gk_Slider1 then gk_Slider1 = kvalue event "i", "TableEdit", 0, 1 endif endin instr TableEdit kndx = 0 loop: kres table kndx, gi_ExponentialTable tablew kres * gk_Slider1, kndx, gi_WriteTable loop_lt kndx, 1, gi_TableSize, loop event "i", "OSCSend", 0, 1 turnoff endin instr OSCSend S_Table = "" indx = 0 loop: ires table indx, gi_WriteTable Sout sprintf "%f ", ires S_Table strcat Sout, S_Table loop_lt indx, 1, gi_TableSize, loop OSCsend 0, "", 4444, "/csound", "s", S_Table endin </CsInstruments> <CsScore> i "Init" 0 10000 </CsScore> </CsoundSynthesizer> I'm using a slider widget and every time it moves it triggers an instrument which reads from a table, scales its values and then writes them to the table I want to send over OSC. This then triggers the OSCSend instrument which concatenates the table numbers to a string and sends them over OSC. Along with the crashing Csound also complains of buffer overflows if my table is too big, I'm using a size of 16 here, but it complains at 32. Any ideas?

	hello, this is not a solution, more for discussion: the osc library http://liblo.sourceforge.net/docs/group__liblo.html has declared a type blob - basically an array of binary data created with function lo_blob lo_blob_new (int32_t size, const void data) Create a new OSC blob type. I think it is not implemented in Csound and not sure if other programs support it eihter, but in such cases (to forward a lot of data) it could be the ideal solution. greetings, tarmo On Thursday 22 September 2011 10:12:59 Victor.Lazzarini@nuim.ie wrote: > Why are you sending numeric data as strings?

	I tested your code here and I am positive that using a slider like that is your source of trouble. There are simply too many OSC messages being sent. It's not what OSC is designed for. Use a button to trigger new messages and you will see no crashes.

	yes, I think it is a part of liblo. I wrote a very simple test program (also attached): -------- // to test, if sendosc blob type works // link with -llo flag #include #include #include #define LENGTH 5 int main() { lo_address target=lo_address_new("localhost", "8888"); int res; float data[LENGTH]={0.0,0.1,0.2,0.3,0.4}; lo_blob myblob=lo_blob_new(sizeof(data[0])LENGTH, data); if ((res=lo_send(target,"/blob/test","b",myblob))==-1) { printf("Error in sending blob\n"); return -1; } return 0; } --------- running oscdump in another terminal reported correctly: ~> oscdump 8888 /blob/test b [20 byte blob] The maximum length that one could send with floats is LENGTH 8184 (oscdump): /blob/test b [32736 byte blob] so it is quite a lot. Thus the maximum data sent at once can be 32768 bytes and a bit less ( I think there is some extra info in the blob, I don't know).

Subject	Re: [Csnd] Best way to send Table values over OSC
	Quartz composer has support for receiving arrays of floats over OSC, are these equivalent to OSC blobs? For example you can do an: OSCsend 0, "", 4444, "/csound", "ffff", k1, k2, k3, k4 And this will be interpreted as a size 4 array of OSC floats. I tried changing my widget instrument code so that it only fires the OSC messages when the position of the slider (0.0 - 1.0) multiplied by 10 is an integer. It still stops working after a few seconds though. Is using a button the only option? I am trying to visualize tables in real time using QC as QuteCsound can't do that at this time. The widget instrument is: instr Widgets, 3 kvalue invalue "slider1" kint = int (kvalue * 10) if kint != gk_Slider1 then gk_Slider1 = kint event "i", "TableEdit", 0, 1 endif endin On 22 September 2011 12:15, Tarmo Johannes <tarmo@otsakool.edu.ee> wrote: yes, I think it is a part of liblo.

	I changed the OSC instrument also to this: instr OSCSend gi_Count = gi_Count + 1 ; S_Table = "" ; indx = 0 ; loop: ; ires table indx, gi_WriteTable ; Sout sprintf "%f ", ires ; S_Table strcat Sout, S_Table ; ; loop_lt indx, 1, gi_TableSize, loop i1 table 0, gi_WriteTable i2 table 1, gi_WriteTable i3 table 2, gi_WriteTable i4 table 3, gi_WriteTable i5 table 4, gi_WriteTable i6 table 5, gi_WriteTable i7 table 6, gi_WriteTable i8 table 7, gi_WriteTable i9 table 8, gi_WriteTable i10 table 9, gi_WriteTable i11 table 10, gi_WriteTable i12 table 11, gi_WriteTable i13 table 12, gi_WriteTable i14 table 13, gi_WriteTable i15 table 14, gi_WriteTable i16 table 15, gi_WriteTable OSCsend 0, "", 4444, "/csound", "ffffffffffffffff", i1, i2, i3, i4, i5, i6, i7, i8, i9, i10, i11, i12, i13, i14, i15, i16 print gi_Count endin This instrument is called less often than I had before because I changed the code to send OSC messages every 1/10 the length of the slider I was using. I thought this way would work properly but strangely it stops working exactly after 242 calls of the OSCSend instrument, this also happens if I just send 8 values instead of 16. I found this error in the console when it stopped working: qutecsound-f[1022]: dnssd_clientstub deliver_request: socketpair failed 24 (Too many open files) QuteCsound also cannot save any changes to open files after this error.

Too many open files woriesme as I would not expect any files to be opened. Can you remind me which platform this is? I am fairly sure that the Csound/OSC code does not open files, so either liblo is or your code is.... ==John ff Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"

	I rewrote my code so a lot of the work is done by just one instrument. I don't know how the OSCSend works in Csound, but It seems that every time the instrument that sends the OSC messages is called it instantiates another OSC sender that is not removed when the instrument is turned off. When the amount of instantiated OSC senders reaches 242 it seems to run out of memory and just stops working.

	It looks as if there is no code to remove listeners. I think I was expecting people would have universal instruments for this. Staring at the code but not sure where to fix. Looks like the need for a destructor. ==John ff > I rewrote my code so a lot of the work is done by just one instrument.
