ello,

I'm trying an instrument, which works in csound but seems to freeze python, like an infinite loop or something. I've pasted both, the csd and the python code.

p2 is small (.0001) but that's only a frequency of 10000Hz, and it works in real time in  a normal csd.

Best,

Thanks Victor,

A couple of questions below.

On 18 May 2013 09:59, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:

The "freeze" in Python is an infinite loop in i-time. It's pretty much like setting start time to 0 (as in Rory's code). The

reason for this is that the interval between one event and the next is less than 1-kcycle, so the start times are quantized

to 0, and you're stuck in i-time.

Would this be the case with the sample-accurate mode too?

It's not a real "freeze", because you can exit Csound by calling csoundReset() (perf.Stop() will not do anything as the

performance is stuck in i-time).

I tried this and it works. But after I've called csoundReset(), the next time I try to compile and instrument nothing happens. In fact csoundReset() followed by Stop() doesn't work either. Is this normal? 

If you want to do start times that short, you will need to put in a counter with a check for a max number of instances and cuttoff at that point.

Or reduce ksmps.

Effectively, because you're not doing any check to come out of the i-time loop, you need to observe the minimum 1/ksmps interval

between spawn events.

I see. I'll put some checks in place then!

Thanks very much

Peiman

I get the impression that the issue of calling schedule with effective
0 start gets us the loop due to appending to the event chain. If we
prepended instead, that might be a way to never run into this problem,
as Csound would keep going down the chain (not sure what would happen
in the parallel case).  If we're scheduling for another instrument,
the behavior should be the same where it will get rendered in the same
k-pass. I imagine there could be issues with prepending, so this just
might be a user coding issue to solve.

Wouldn't an easy solution be to have an internal check in place so that all the event opcodes have a minimum of one k-period, while printing a warning?

I'm just thinking that in a live-coding situation it is easy to make a mistake and set the value to 0, and it wouldn't be so good if the entire performance was halted as a result.

as Csound would keep going down the chain (not sure what would happen

the behavior should be the same where it will get rendered in the same
k-pass. I imagine there could be issues with prepending, so this just
might be a user coding issue to solve.

Also, with --sample-accurate option on, shouldn't the events be quantised to the sample period?

I don't think that'd quite work.  Currently, if you have an instrument
that then calls, say, 2 others, a user might expect that all 3 play in
tandem.  If they're on ksmps off, the other 2 will be off, and if the
user is relying on them being in sync it could cause unexpected
beating, etc.  Granted, I'm not sure that's a great use of schedule,
but I also don't want to break anyone's pieces if they did use it that
way.

Sample accurate does not come into play here, because the events are always scheduled to start at a given kcycle, sample accuracy only makes the actual synthesis start at the right time in

the cycle. The problem is that this is an infinite loop. 

If you reset, you will need to start csound and a new thread again to perform, otherwise, nothing happens.

Thanks Victor,

A couple of questions below.

On 18 May 2013 09:59, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:

The "freeze" in Python is an infinite loop in i-time. It's pretty much like setting start time to 0 (as in Rory's code). The

reason for this is that the interval between one event and the next is less than 1-kcycle, so the start times are quantized

to 0, and you're stuck in i-time.

Would this be the case with the sample-accurate mode too?

It's not a real "freeze", because you can exit Csound by calling csoundReset() (perf.Stop() will not do anything as the

performance is stuck in i-time).

I tried this and it works. But after I've called csoundReset(), the next time I try to compile and instrument nothing happens. In fact csoundReset() followed by Stop() doesn't work either. Is this normal? 

If you want to do start times that short, you will need to put in a counter with a check for a max number of instances and cuttoff at that point.

Or reduce ksmps.

Effectively, because you're not doing any check to come out of the i-time loop, you need to observe the minimum 1/ksmps interval

between spawn events.

I see. I'll put some checks in place then!

Thanks very much

Peiman

ello,

I'm trying an instrument, which works in csound but seems to freeze python, like an infinite loop or something. I've pasted both, the csd and the python code.

p2 is small (.0001) but that's only a frequency of 10000Hz, and it works in real time in  a normal csd.

Behaving erratically how? You need to give an example. Just saying this does not help.

I'm just thinking that in a live-coding situation it is easy to make a mistake and set the value to 0, and it wouldn't be so good if the entire performance was halted as a result.

Just to note, when you're using the API, be careful with the order of operations, etc, because you can easily create programs that

don't work or break down, and  it is not the API's fault. This is a level down from using Csound as a language.

If you have found a bug, make sure it is not your program and it is a genuine one, then report through the bug tracking system.

Doing the tests etc before reporting, will allow us to use our time more efficiently, esp. now at this point when we are busy getting

the new release into shape.

Just to note, when you're using the API, be careful with the order of operations, etc, because you can easily create programs that

don't work or break down, and  it is not the API's fault. This is a level down from using Csound as a language.

If you have found a bug, make sure it is not your program and it is a genuine one, then report through the bug tracking system.

Doing the tests etc before reporting, will allow us to use our time more efficiently, esp. now at this point when we are busy getting

the new release into shape.

Behaving erratically how? You need to give an example. Just saying this does not help.

I can confirm that csoundReset() is behaving erratically. I can't really predict it's outcome.

Also, with --sample-accurate option on, shouldn't the events be quantised to the sample period?

Wouldn't an easy solution be to have an internal check in place so that all the event opcodes have a minimum of one k-period, while printing a warning?

I'm just thinking that in a live-coding situation it is easy to make a mistake and set the value to 0, and it wouldn't be so good if the entire performance was halted as a result.

I get the impression that the issue of calling schedule with effective
0 start gets us the loop due to appending to the event chain. If we
prepended instead, that might be a way to never run into this problem,
as Csound would keep going down the chain (not sure what would happen
in the parallel case).  If we're scheduling for another instrument,
the behavior should be the same where it will get rendered in the same
k-pass. I imagine there could be issues with prepending, so this just
might be a user coding issue to solve.
