I am trying to run my csd with the superformula in CsoundQt-d-py-cs6, but it hangs.

The last thing csound reports is:

writing 1024 sample blks of 64-bit floats to dac1

SECTION 1:

ftable 1:

new alloc for instr 1:

Richard

Ok, here it is:

Please send the csd (or resend if it was in an earlier email).

Hi,

Thanks!

I get the same result. Seems, the problem is in function R. When I run the 
original version in terminal I get output:

new alloc for instr 10:

  --> Sample Rate: 48000.0, Control Rate: 480.0


  --> TableGet: 0.0, len:16384

__main__:7: RuntimeWarning: divide by zero encountered in double_scalars
B  0.000 ..  1.000 T  1.000 TT  1.000 M:  0.00000  0.00000
Score finished in csoundPerform().
inactive allocs returned to freespace
end of score.              overall amps:  0.00000  0.00000
           overall samples out of range:        0        0
0 errors in performance

Pay attention to the divide by zero warning that is caused probably by

r = np.abs(np.abs(np.cos(m * rho / 4.0)) / a) ** n2 + np.abs(np.abs(np.sin(m * 
rho / 4.0)) / b) ** n3

If I simplified the instrument for testing:
instr 1
  ; Use the cs python object
  pyruni {{
print("\\n  --> Sample Rate: {}, Control Rate: {}\\n".format(cs.sr(), 
cs.kr()))
l = cs.tableLength(1)
print("\\n  --> TableGet: {}, len:{}\\n".format(cs.tableGet(1,0), l))

i = 0

Thanks! I did not notice the divide by 0 warning. Now I can use the 
widgets to create nice sliders for input of the params.

I am now thinking of not using oscil and tables because that always 
produces one period, which is not so interesting.

When the superformula is used with changing arguments the sounds will 
become very interesting I guess.
So I am going to create a longer waveform in a table and play that with 
flooper or similar..

Still something strange is going on. I do not see where the divide by 
zero could come from with the variables I use.
I tried adding the 'from __future__ import division' line, but then it 
complains with:

NameError: name 'cs' is not defined

Here is that part of the  code:

pyruni {{
import ctcsound
import sys
import numpy as np
#from __future__ import division   # when this line is uncommented 'cs' 
is not defined

# Get an opaque pointer to the running Csound instance
# and print Python version number
p = _CSOUND_
print("\\n  --> Python version number: {}\\n".format(sys.version_info[0]))
# Create an object called cs from the ctcsound.Csound class
# using the opaque pointer to the Csound instance
cs = ctcsound.Csound(pointer_=p)        #<======
}}

Ok thanks, I also test now for rho being zero. When I run this in CsoundQt, it only works the first time.
When I run it again, it always hangs...
The modified csd is attached.

Richard

The divide by zero error is due to np.sin which is evaluated to 0 when rho is 0. As n3 is negative, the power function returns an -inf value (divide by zero). In normal context, the second power function **(-1/n1) yields the zero value, canceling the effect of -inf. If Csound runs in his own thread, CsoundQt should not block...

Hi,

Thanks!

I get the same result. Seems, the problem is in function R. When I run the
original version in terminal I get output:

new alloc for instr 10:

  --> Sample Rate: 48000.0, Control Rate: 480.0


  --> TableGet: 0.0, len:16384

__main__:7: RuntimeWarning: divide by zero encountered in double_scalars
B  0.000 ..  1.000 T  1.000 TT  1.000 M:  0.00000  0.00000
Score finished in csoundPerform().
inactive allocs returned to freespace
end of score.              overall amps:  0.00000  0.00000
           overall samples out of range:        0        0
0 errors in performance

Pay attention to the divide by zero warning that is caused probably by

r = np.abs(np.abs(np.cos(m * rho / 4.0)) / a) ** n2 + np.abs(np.abs(np.sin(m *
rho / 4.0)) / b) ** n3

If I simplified the instrument for testing:
instr 1
  ; Use the cs python object
  pyruni {{
print("\\n  --> Sample Rate: {}, Control Rate: {}\\n".format(cs.sr(),
cs.kr()))
l = cs.tableLength(1)
print("\\n  --> TableGet: {}, len:{}\\n".format(cs.tableGet(1,0), l))

i = 0
#while i<l:
val = cs.tableGet(1, i)
#val = R(i, 1., 1., 8., 10., -1., -8.)
cs.tableSet(1, i, val)

  }}
endin

And then it works.

I am not sure yet why CsoundQt hangs on the first error -  probably some thread
is not returning or some other kind of deadlock happens but seems that if
python code is correct, ctcsound should work within CsoundQt. Did not test
thorougly, though.

tarmo

Hi!

I got back to this. For me your csd works fine -  python part does it job, 
sound is produced, no crash on second nor nth start. I am on Linux, CsoundQt 
built with pythonqt support. I tried recent build from develop branch and also 
CsoundQt 0.9.5.

On which platform are you? Does your csd works if you use Run in Term?

greetings,
tarmo
