QUESTION
I am trying to figure out if it is possible to add effects to a new track in the sequencer just like you would with a instrument.
So far I haven’t been able to figure it out based on the docs, but the idea is to be able to sequence parameters for a selected effect just like you would with midi note information such as velocity, length and pitch/note for AudioKit instruments. Say if you wanted to sequence a low pass filter; you would have access to sequence the cutoff frequency and resonance etc.
Any ideas if this is achievable with AudioKit?
Thanks in advance.
...ANSWER
Answered 2021-May-19 at 18:25You could represent the parameter changes you want to sequence inside MIDI events, add those events to a sequencer track, add the track to a sequencer and connect the sequencer track to a callback instrument. The callback instrument would change the low pass filter's parameters.
So the outline of the process would be:
SequencerTrack -> Callback instrument -> Low pass filter's parameters
It might not be an ideal solution because you would be calling a Swift function from the DSP and back into the DSP from Swift, but it's the only solution that comes to mind without writing your own custom DSP code.

in your specific case isn't a valid JSON payload - as it has the ###... EventGrid trigger processing an event:
prefix (and a somewhat similar suffix).
- That is why
todynamic()
isn't able to process it and why you're not able to reference properties in the JSON payload that's included in it.
Ideally, you would change the payload you ingest to be a valid JSON payload, and re-type the target column to dynamic
instead of string
.
If you can't do that, you can use the substring()
function or parse
operator to get everything but the aforementioned prefix/suffix, and parse the output of that using todynamic()
- though note that doing that each time you query the data bears runtime overhead that could be avoided by following the advice above.
QUESTION
I am trying to build a small sequencer with my kids and struggle to find a solution on this.
I am using this library: https://github.com/alemangui/pizzicato
Our goal is to create little samples of their voice and have them playing one after the other(but not at the same time).
I wrote this code hoping to solve the problem but upon playing on "Play", all the samples play at the same time rather than 1 after the other...
...ANSWER
Answered 2021-Apr-11 at 16:38The callback you pass while initializing the Pizzicato.Sound
class is run immediately when the sound is ready to play.
So it's best to get all the sounds, pick one sound, play it and listen for it's end event
and call the next sound.
QUESTION
Say I want to trigger a random note and velocity on an instrument every quarter note. What is the best way to achieve this in AudioKit V5?
The examples seem to use the sequencer to schedule sounds with proper timing, but then you have to add in the notes to the track in advance.
One solution is to pre-generate a bar of random quarter notes with looping enabled - when the bar of random notes is complete, clear the bar and replace with new random notes.
I'm wondering if there's a lower level way of doing this? Some kind of callback that is called with precise timing where I can generate the values as they're needed? Or another approach?
...ANSWER
Answered 2021-Apr-09 at 06:44There's nothing that enforces you to have to obey the incoming note data or velocity from the sequencer. Just make your instrument respond to any note ons with a random note and velocity. That way you get the timing without worrying about anything else.
QUESTION
Every beat has a drum snare (1,2,3,4) So "beat" id it's a screen that shows the count.
I want, without stopping the count from the memory, if I click the "beat" button to write "disable" on the screen (1,2,3,4). If I click enable the beat, continue from where it was left and write enable. But I do not want the count from the memory to stop. Is it possible?
beat means screen on css k means snare sound on sequencer. Pattern means sequencer pattern step means beat on sequencer
...ANSWER
Answered 2021-Mar-27 at 19:24I had a bit of difficulty understanding your use case, but this example should show how you can store the count in a variable called count
and display that value on the screen whenever you choose. (It also uses the built-in setInterval
function to advance the count every second.)
The disabled
variable keeps track of whether the display is in a disabled state, and the playOrPause
function uses this information to decide whether to 1) resume the timer and show the current count or 2) stop the timer and show the "Disabled" message.

So I'm fairly new to both AWS and Python. I'm on a uni assignment and have hit a road block.
I'm uploading data to AWS S3, this information is being sent to an SQS Queue and passed into AWS Lambda. I know, it would be much easier to just go straight from S3 to Lambda...but apparently "that's not the brief".
So I've got my event accurately coming into AWS Lambda, but no matter how deep I dig, I can't reach the information I need. In AMS Lambda, I run the following query.

Answered 2021-Mar-26 at 01:22You are having this problem because the contents of the body

QUESTION
I am trying to write a Javascript recursive function to help with calculations on another project, and I'm running into issues when trying to write out the function and get it to work as intended. I know some Javascript, but I'm no expert, so apologies if there may be some bad practices in my code. I have a function called quadraticSequencer
that takes in an argument, num
, and generates a quadratic sequence up to the given input num. It then returns the final output to be used and passed into the following function, subtraction
. This is where the first issue occurs and the logic doesn't run as intended... ( where it should just return the last output in the sequence and pass it into the subtraction
function, it seems to pass only the first output only and stops. )
The subtraction
function takes in two arguments, num
and nthTerm
(which was returned and passed in from the quadraticSequencer
function ), and runs a recursive function that redefines nthTerm
as level
and takes the level
and subtracts it from num
to generate a result
, or const result = num - level
. An if / else statement runs to check the result for divisibility using the modulo % operator, and if passes it console.logs result
. If failed it moves to the next level
(or iterative step down) and subtracts that from the PREVIOUS result
and NOT num
. That last part is critical because I'm not sure how to execute this logic correctly so that the previous result
is stored for the next subtraction.
i.e. if num = 75, nthTerm
would be 11, and the subtraction
function would subtract 75 like so:
75 - 11. result = 64 || 64 - 10. result = 54 || 54 - 9. result = 45 || 45 - 8. result = 37 || 37 - 7. result = 30 || 30 - 6. result = 24 || 24 - 5. result = 19 || 19 - 4. result = 15 || 15 - 3. result = 12 || 12 - 2. result = 10 || 10 - 1. result = 9.
Hopefully, that makes sense. This is just how the subtraction has to run for our calculations to be accurate. If the first run-through finishes, it also does a "double-run" and adds more subtractions, basically subtracting in reverse and adding on more subtractions, not removing subtractions. So a full run with no passes would look like this: 75-11-10-9-8-7-6-5-4-3-2-1-1-2-3-4-5-6-7-8-9-10-11. Checking every result
per subtraction. I wasn't sure how to write this within the if / else statement.
The overall expected output is to get the last output from the quadtraticSequencer
function to pass it into the subtraction
function for calculations, and the subtraction
function be able to run as intended. So when num = 75
, the subtraction
function should pass when the level
or "step" is 4 and the result
= 15, or 75-11-10-9-8-7-6-5-4 = 15. 75 % 15 = 0. // 15
Here's my code:
