I have created separate groups on supercollider for each instrument so that I may apply FX, like echo, to the group and only affect one instrument rather than all instruments playing on that sc server.
On the node tree, the echo synthdef correctly appears in the required group (box) and the FX is applied to the instrument in that group, but ALSO incorrectly applying echo to the nodes in other groups on the same server.
What I have noticed is that it affects all higher number groups and not lower number groups. Applying FX (echo) to group 1 or group 2 also applies the same FX to groups 3,4,5,6,7,8, etc., but applying FX to group 8 does NOT seem to affect groups 1,2,3,4,5,6,& 7.
I have tested this on the following systems/versions....
supercollider version (1:3.10.0+repack-1ubuntu2) on ubuntu (Linux
Optiplex-3010 5.4.0-70-generic #78-Ubuntu SMP x86_64 x86_64 x86_64
GNU/Linux)
supercollider version (1:3.10.0+repack-1+rpi1) on Linux raspberrypi
4.19.75-v7l+ #1270 SMP armv7l GNU/Linux
supercollider version (1:3.8.0~repack-2) on Linux advent
5.0.0-32-generic #34~18.04.2-Ubuntu SMP 2019 i686 i686 i686 GNU/Linux
Is this a known bug? Can I make any manual changes to the supercollider code to resolve this? If not, then it will have to be a separate RPi4 for each instrument, underutilising each RPi and increasing project costs significantly.
Regards to all SCcoders,

Requested code:
(SynthDef(\echo,{|in, out, length = 1, fb = 0.6, sep = 1|
var input = In.ar(in, 2);
var feedback = LocalIn.ar(2);
var output = LeakDC.ar(feedback*fb + input);
LocalOut.ar(DelayC.ar(output, length, sep));
ReplaceOut.ar(out, output);
}).writeDefFile("/home/phil/Supercollider/syndef");)
I instigate the echo via OSC over tcp/ip, but essentially it would be called by:
/s_new s 'echo' i 1028 i 0 i 8 //in this case 1028 is the node for track 8
//and 8 is the SC group
and adjusted by:
/n_set i 1028 s 'fb' f 0.7
UPDATE: In answer to Fizz's comment about...
how I created groups, initially in the startup.scd file and then clear every time the live performance stops and create every time the live performance starts...
oscStream.Clear();
oscStream << osc::BeginBundleImmediate
<< osc::BeginMessage("/g_freeAll") << 1 << osc::EndMessage
<< osc::BeginMessage("/clearSched") << osc::EndMessage
<< osc::EndBundle;
transmitSocketMelody1.Send(oscStream.Data(),oscStream.Size());
oscStream.Clear();
oscStream << osc::BeginMessage("/g_new") << 1 << 0 << 0
<< osc::EndMessage;
transmitSocketMelody1.Send(oscStream.Data(),oscStream.Size());
oscStream.Clear();
oscStream << osc::BeginMessage("/g_new") << 2 << 0 << 0
<< osc::EndMessage;
transmitSocketMelody1.Send(oscStream.Data(),oscStream.Size());
which is the equivalent of...
s.sendMsg(\g_freeAll, 0);
s.sendMsg(\clearSched);
s.sendMsg(\g_new,1,0,0);
s.sendMsg(\g_new,2,0,0);
Order that I create synthdefs...
The echo synthdef (already shown above) is the first created via the supercollider startup.scd file.
Then the sound synthdefs are created in numerical order Piano1, Piano2, Piano3, etc... also via the supercollider startup.scd file.
s.sendMsg(\b_allocRead, 101,"piano-p-c4.wav"); //buffer 101
SynthDef.new("piano1", {|amp=1, freq|
var output,sig,sig2;
sig=PlayBuf.ar(2, 101, freq/523.25, doneAction:2);
sig=sig*amp;
sig = Splay.ar(sig);
Out.ar(0,sig!2);
}).store;
s.sendMsg(\b_allocRead, 111,"piano-p-c5.wav"); //buffer 111
SynthDef.new("piano2", {|amp=1, freq|
var sig;
sig=PlayBuf.ar(2, 111, freq/523.25, doneAction:2);
sig=sig*amp;
sig = Splay.ar(sig);
Out.ar(0,sig!2);
}).store;
The piano synthdefs are played live from the commands..
oscStream_melody1 << osc::BeginMessage("/s_new")
<< "piano1"
<< NextSCNode << 0 << 1
<< "freq" << OscFrequency[OSCOctave][OSCNote]
<< "amp" << Melody1Amplitude*Melody1Volume
<< osc::EndMessage
transmitSocketMelody1.Send(oscStream_melody1.Data(),oscStream_melody1.Size());
oscStream_melody2 << osc::BeginMessage("/s_new")
<< "piano2"
<< NextSCNode << 0 << 2
<< "freq" << OscFrequency[OSCOctave][OSCNote]
<< "amp" << Melody2Amplitude*Melody2Volume
<< osc::EndMessage;
transmitSocketMelody2.Send(oscStream_melody2.Data(),oscStream_melody2.Size());
which is the equivalent of...
s.sendMsg("/s_new","\piano1",1234, 0, 1,"freq",440,"amp", 0.8)
s.sendMsg("/s_new","\piano2",1235, 0, 2,"freq",880,"amp", 0.7)
echo is turned on, modified and off live thus...
s.sendMsg(\s_new,'echo',1001,0,X); //where X is the group to apply to
s.sendMsg(\n_set, 1001,'fb',0.5,'length',1,'sep',1);
s.sendMsg(\n_free, 1001);
but this turns on the echo for all groups with higher numbers, e.g group2, group3, group4 etc.
Whereas if reverb is set on group2 it affects group3, group4, etc but not group1.
Without seeing any code, this is hard to answer, but I wonder if you are using buses? Your instrument group should output to an echo bus and that bus should output to where you wish the sound to go next - another FX bus or to 0.
You'd want to draw a block diagram of your groups, connecting inputs and outputs. Keep in mind that any FX group can take ins from multiple places, but will only have one output. This means you may end up running the same FX synth more than once, for example, if you want echo on groups A and B, but then you want group B to go to a compressor afterwards.
Make sure to declare every bus, give it a good variable name and remember to pass it as an argument on synth creation.
I have this links.csv file:
METHOD,HOST,PATH,HITS
GET,google.com,/,7
GET,facebook.com,/,3
I want to create a JMeter test plan using Ultimate Thread Group (UTG) that randomize the hits based on the last column in the CSV above (HITS).
When viewing the results tree, I want to see something like this:
1. google.com
2. google.com
3. facebook.com
4. google.com
5. google.com
6. google.com
7. google.com
8. google.com
9. facebook.com
10. facebook.com
Ideally, I want to set the UTG to use the following settings:
Start Threads Count = sum of all hits in the CSV file (e.g. 7 + 3)
Initial Delay = 0
Startup Time = 60
Hold Load For = 30
Shutdown Time = 0
How to achieve this? I appreciate code samples and screenshots since I'm still new to JMeter.
I can only think of generating a new CSV file out of your original one in order to:
Get the "sum" of "HITS"
Generate a line containing method, host and path per "hit"
In order to achieve this:
Add setUp Thread Group to your Test Plan
Add JSR223 Sampler to the Thread Group
Put the following code into "Script" area:
def entries = new File('/path/to/original.csv').readLines().drop(1)
def sum = 0
def newCSV = new File('/path/to/generated.csv')
newCSV << 'METHOD,HOST,PATH' << System.getProperty('line.separator')
entries.each { entry ->
def values = entry.split(',')
def hits = values[3] as int
sum += hits
1.upto(hits, {
newCSV << values[0] << ',' << values[1] << ',' << values[2] << System.getProperty('line.separator')
})
}
props.put('threads', sum as String)
Use __P() function like ${__P(threads,)} in the Ultimate Thread Group
Use the new "generated" CSV file in the CSV Data Set Config in the Ultimate Thread Group
I am trying to make an app for vacation requests but i am facing a problem.I have e model called VacationRequest and a view of VacationRequest where the result will be shown.
VacationRequest.rb model
def skip_holidays
count1 = 0
special_days = Date.parse("2017-05-09", "2017-05-12")
special_days.each do |sd|
if ((start_data..end_data) === sd)
numero = (end_data - start_data).to_i
numro1 = numero - sd
else
numero = (end_data - start_data).to_i
end
end
end
VacationRequest show.htm.erb
here i called the method from model
#vacation_request.skip_holidays
this is showing errors and is not working. Please help me with that!
My approach to this would be the following:
def skip_holidays
special_days = ["2017-05-09", "2017-05-12"].map(&:to_date)
accepted_days = []
refused_days = []
(start_data..end_data).each do |requested_date|
accepted_days << requested_date unless special_days.include?(requested_date)
refused_days << requested_date if special_days.include?(requested_date)
end
accepted_day_count = accepted_days.count
refused_days_count = refused_days.count
end
This way you iterated over all requested dates (the range), checked if the date is a special day - If so, refuse it, otherwise accept it.
In the end you can display statistics about accepted and refused dates.
You cannot create a date range by passing multiple argument to the constructor. Instead call the constructor twice to create a range:
special_days = Date.parse("2017-05-09") .. Date.parse("2017-05-12")
Or if instead you want only the two dates, do:
special_days = ["2017-05-09", "2017-05-12"].map &:to_date
This Date.parse("2017-05-09", "2017-05-12") don`t create a range, only return the first params parsed:
#irb
Date.parse("2017-05-09", "2017-05-12")
=> Tue, 09 May 2017
You can do it this way:
initial = Date.parse("2017-05-09")
final = Date.parse("2017-05-12")
((initial)..final).each do |date|
#rules here.
end
I'm new to AnyLogic and I am trying to create a custom network...but i don't get to succeed in this task :(
Agents have a parameter "AgeClass", that is an int from 0 to 14, according to their age.
Then I have a variable "network" that contains the mean number of links between age class.
What I want is every agent to create link with other agent according to the matrix.
I don't get how I can say to an agent "connect to another agent with AgeClass = 3"
I thought something like this (to put in the "on startup block" or in an event inside the agent type):
int i = AgeClass \\ this is the AgeClass of the agent who is executing the code
for( int j=0; j<network[i].length; j++ ) { \\ in this way I go through all the age classes
for ( int k=0; k<poisson(network[i] [j]); k++) { \\ for every j I get the mean # of link
connectTo(????);
}
}
Instead of ???? i want to say "connect to another agent with AgeClass = j" ...is there a way thorugh?
Thanks for the support!!!
Please use the function "filter()" to select all agents from the population with AgeClass = j. Then, you can get random of them to connect to the agent executing the code. The expression ???? may look like:
randomFrom(filter(main.people, p -> p.AgeClass == j))
Here is the description of the function "filter()":

I am trying to change one example to take a user input rather than using hard coded values then use those local variables to work out items needed.
So far my code looks like this:
print "Number of cars available today."
cars = gets.chomp()
print "Number of available seats in the car."
space_in_a_car = gets.chomp()
print "Number of drivers available."
drivers = gets.chomp()
print "Number of passagers that need transport."
passangers = gets.chomp
cars_not_driven = #{cars} - #{drivers}
cars_driven = drivers
carpool_capacity = #{cars_driven} * #{space_in_a_car}
average_passanger_per_car = #{passangers} / #{drivers}
print "The number of cars being driven today is #{cars_driven}.\n"
print "The number of cars not being driven today is #{cars_not_driven}.\n"
print "We have #{carpool_capacity} cars available.\n"
print "So we need to carry #{average_passanger_per_car} passangers per car to make sure we can transport everyone.\n"
The code will run without throwing any errors but of course because I am not getting the correct commands in:
cars_not_driven = #{cars} - #{drivers}
cars_driven = drivers
carpool_capacity = #{cars_driven} * #{space_in_a_car}
average_passanger_per_car = #{passangers} / #{drivers}
the only value I am getting in the return is:
print "The number of cars being driven today is #{cars_driven}.\n"
How should I be writing:
cars_not_driven = #{cars} - #{drivers} etc
to get the number of cars_not_driven?
I don't understand very well why you use this #{var} and <br>. If I am right that you want to use plain ruby, this should be the solution:
print "Number of cars available today."
cars = gets.chomp().to_i
print "Number of available seats in the car."
space_in_a_car = gets.chomp().to_i
print "Number of drivers available."
drivers = gets.chomp().to_i
print "Number of passagers that need transport."
passangers = gets.chomp.to_i
cars_not_driven = cars - drivers
cars_driven = drivers
carpool_capacity = cars_driven * space_in_a_car
average_passanger_per_car = passangers / drivers
print "The number of cars being driven today is #{cars_driven}.\n"
print "The number of cars not being driven today is #{cars_not_driven}.\n"
print "We have #{carpool_capacity} cars available.\n"
print "So we need to carry #{average_passanger_per_car} passangers per car to make sure we can transport everyone.\n"
When you use gets Ruby is expecting and returning a String. So variables car, drivers etc are all String.
In order to do integer operation over them, you need to convert them to integers. In Ruby you can do this using .to_i.
Now with that information, try:
cars_not_driven = cars.to_i - drivers.to_i
cars_driven = drivers.to_i
carpool_capacity = cars_driven * space_in_a_car.to_i
average_passanger_per_car = passangers.to_i / drivers.to_i
You can check the class of a variable using .class. Here:
cars = gets.chomp()
10
# => "10"
cars.class
# => String
drivers = gets.chomp()
20
# => "20"
drivers.class
# => String
Now lets add them:
cars + drivers
# => "1020"
Since they are string, + operator is adding two strings to one. Not something you intended. Now try this:
cars.to_i + drivers.to_i
# => 30
