QUESTION
I've been working on a project with an Arduino recently where I'm basically trying to get a small display hooked up to an Arduino to update with the name of a MIDI mapped knob in Ableton Live.
For example, let's say I map the knob to the reverb send on a track the display should read "A-Reverb". This works today, but only works when I first open the Ableton project and map the knob for the first time. It does not update when I select a new option.
Here's the setup I'm using right now:
- Arduino - w/Rotary Encoder & OLED Display
- Hairless MIDI - For converting the serial connection from the Arduino into MIDI CC# messages Live can read.
- Ableton Live 11 w/ Max For Live 8 - This is where the patch actually runs.
For the Max Patch, I'm using a version of Yehezkel Raz's One which I purchased and later modified. The reason I mention this is that this patch already has the name updating part worked out, so in theory I should be able to send that data over serial to the Arduino.
Out of respect for Yehezkel's work, I won't attach a screenshot of the entire patch, but have attached the part that I modified to send data to the Arduino, you can see it here.
Here's what I've tried so far:
- Validated that the baud rate for Hairless MIDI, the Arduino, and the Max Patch is identical
- Attempted to start Hairless MIDI only after Ableton has been launched
- Attempted to power on Arduino without opening the Arduino IDE so that there are no Serial conflicts.
Here's what I think may be the issue, but I'm not sure how to fix it:
- Part of the logic in my Arduino code relies on
Serial.available()
being true, in order to send the data to the screen. I'm thinking that maybe the Serial connection is only available in the beginning when the knob is mapped.
I know that was a lot of information, but if anyone has any ideas on how I may be able to get this to work, I'd greatly appreciate it!
...ANSWER
Answered 2021-Apr-28 at 16:37Okay I figured this out on my own; basically what was happening was my code was expecting a line feed in order to refresh the output on the display. I figured out that I could send a line feed over the serial connection by sending the value "10" which would basically terminate the string as it is sent to the Arduino.
Any time the knob value is updated, it triggers a button which sends the value "10" back to the Arduino.
I've attached a screenshot showing the changes I made in case this helps anyone else out:

QUESTION
I have created an MP3 player in a Xamarin project, and it plays great. I have added the ability to adjust the Pitch and Speed, but I cannot get the Reverb effect to take to my MediaPlayer.
I have found various examples in Kotlin and Java of the code required to create both PresetReverb and EnvironmentalReverb methods to achieve this.
While my C# code runs and produces no errors, the Reverb effect will not apply using either method. I am new to Xamarin and Android, so I am hoping to get some help.
Here is my code.

QUESTION
For DAW automation I want to use Behringers X-Touch Mini encoders (the knobs) to drive different behaviours depending on the state of the buttons below - i.e. if the first button is active then it should modify a channel's gain, if the second button is active it should modify a channel's send to reverb. I do have a easymidi node.js program in place to receive and send MIDI commands from/to the X-Touch (Standard Mode, according to the documentation).
To do so i need to switch the values that are displayed on an encoder depending on the buttons below. This is where I am facing a problem: It seems that the MIDI commands for LED Ring Remote Control (Value Change) do only affect the LEDs itself, not the internally stored value and become obsolete as soon as you turn the knob again.
One example:
- turn the first encoder fully to the right - the last LED will light up - that will emit MIDI commands with 127 as value
- then set the LED of that encoder to the first LED using the MIDI command CC 9 with value 1 (first LED on)
- the first LED will light up
- then slightly turn the encoder knob to the left: the last LED will light up again and will send high values starting with 127
For my intended application it is, therefore, not possible to switch the encoder from one parameter to another, because it would always keep its internal value, regardless of how i set the LEDs
Any thoughts?

QUESTION
I am attempting to manipulate the volume by connecting a MediaElementAudioSourceNode and a GainNode.
Below is a demo of it.
CodeSandBoxs
If you press the Play button, the music plays normally.
However, manipulating input type=range
to change the volume distorts the sound you are playing.(Turn the volume down if you try.)
Is there a way to change the volume without distorting the sound?
Or is this an unavoidable thing if you use MediaElementAudioSourceNode?
I looked for an article that mentions the phenomenon of sound distortion, but I could not find it.
In the demo we only aim to change the volume, but we also want to add reverb, delay, etc.
The demo code is as follows.
...ANSWER
Answered 2020-Dec-08 at 13:02The reason for the distortion is probably that the range of the GainNode
doesn't really map to the range of your input. By default the min/max values of a range input are 0 and 100. However the GainNode
does multiply the signal by its gain value. That means the slider should ideally have a max value of 1.

QUESTION
Using Xamarin, I'd like to use an AVAudioSinkNode to store and eventually transfer incoming audio data from a mic at the lowest latency possible (without going straight into AudioUnits and the deprecated AUGraphs). See my commented code below where the SinkNode is connected to the default InputNode. It's giving me grief. I'm using Xamarin.Forms with a simple iOS dependency class. I can successfully hook up an InputNode through an fx node (Reverb for example) and on out to the OutputNode. In this case, I've minimized my code down to focus on the problem at hand:
...ANSWER
Answered 2020-Aug-15 at 06:37This has been confirmed as a bug: The format parameter is [NullAllowable], but the current code to actually process that null wasn't linked up in the wrapper code. Here's the issue tracker on the Xamarin.Mac/iOS github repo:

QUESTION
i made a website for a game to produce record and share music, some users asked if i could add a reverb option to toggle on/off the reverb (this to simulate being inside a cave), i googled up a bit and found about the webAudio api reverb with the convolver node. I honestly didn't understand much about it but i tried to make it work, in the end i made this:
...ANSWER
Answered 2020-Jun-08 at 15:44A convolver can certainly be used for reverb, but the "buffer" you want to give should not be the same as the audio you're playing. It should instead be given a reverberation kernel (or impulse response), which may be precomputed or an actual recording. It corresponds to how a space reacts to an impulse of sound. You can probably find a suitable royalty free kernel online, never looked for one myself though.
