The proper way is always the low level pre-out.

Connecting it to the speaker output
could blow the input due to overvoltage/negative voltage.

Also the m2 connector is double sided,
which means it's very hard to solder the top side smd pins.

How do you use the AudioEffectPlateReverb?
It's not visible in your posted code
If you use it in the main.cpp then you need to do the include there.

You need to have
#include "effect_platervbstereo.h"
Before the
#include "audioGui.h"
As an alternative you will need to have the
#include "effect_platervbstereo.h"
In the top of audioGui.h

By the looks of it the mcp23s17 can have adressing which means that your only need one CS for all the expanders, the other pins are then connected in parallel.

That was not the proper way of using "anyway" so I removed it

If you connect a nc switch between VIN and VUSB with the external voltage pad cut (the pads in your schematic cutout at the top left)
You would get a complete power cycle reset.

To achieve what you want
you need to split the printBytes into many calls/iterations from the "main"-loop (i.e. multitasking)
Also to do this you probably need to make a copy of the received byte...

Aren't doing Osc1.begin in the main loop a little to fast changing/starting the waveform?
You should only call the .begin function once when the waveform change command is received.

How do you do the note on/off?
Are you using a AudioEffectEnvelope otherwise try that.

of what can understand is that you want to have a constant name output node which just transfers the data from the input to the output
that is basically what you are doing right now

I have updated it with the ladder filter.
Other functionality???


This is a modified version of...

two above bugs fixed

Ohh I forgot about that part, you need a toggled state functionality.
Example for b0


bc = digitalRead(5);
if (bc == LOW) {
if (b0 == LOW) {
b0 = HIGH;
...

You have forgot the else case of


if (b0 == LOW) {
usbMIDI.sendNoteOn(60, 99, 0);
}
else
{
usbMIDI.sendNoteOff(60, 99, 0);
}

You could try to use external pull-up:s . As the internal pull ups are very weak in your case.
You could try different values 10k 4k7 3k3 1k and see where the random clicks dissapear.

I have discovered some bugs that will soon be fixed

Don't think there is any special reason that you should need to do this, except when you are designing very specific audio objects.
You are only making it unnecessary complicated.
