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.

I found a error
at the line in the #if defined(KINETISK) part:

Have looked at the polysynth example
so basically you create a custom "super" Audio object.

It's good implementation

I found one error in your polysynth example...

@Allineer

the ethernet connector is 2.0mm
but all other pins are 2.54mm(0.1")

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

I vote for something like this (to get all pins + extra GND:s)

as homemade pcb:s with 0.15mm tracks is possible (to fit two tracks between each pin)

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.

in platform io the usable flags are:


USB_HID | Keyboard + Mouse + Joystick
USB_SERIAL_HID | Serial + Keyboard + Mouse + Joystick
USB_FLIGHTSIM_JOYSTICK | Flight...

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...

Think you need the different USB flags as well:
(i.e. when using build_flags = -D)

This is how I allocate my poly-synth

but then when I look at the AudioSynthWaveform source code that should not matter,
as the begin function don't do any special things except setting the values,
which if not changed should not...

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

the current version can be downloaded from
https://github.com/manicken/manicken.github.io


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

I have answered that question on your original thread

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.

Otherwise using...

In my modified tool it sorts the items in columns based on the major grid size and then in each column it sorts by the y pos (row)
1 4 7
2 5 8
3 6 9

Your can check my example at https://manicken.github.io
Available at the Tool (top-right menu) -examples-"manicken poly synth"
I belive it's a simple example.
I have used the code from "Notes and...

@palmerr
You could use c++ templates instead
That way nothing is unnessesary allocated.

Have your seen this?

And

with that you can create a voice class like this:

then using the n-mixer use it like this:

There is this extended Tool that allow this.

There is one example at the main menu- examples-poly synth.

If they are poper c++ files
Using classes the merge should be possible without any issues, however if there is non classed functions with the same names in the CPP files then you get conflicts.

Yes its basically a striped down version of the PRO IDE.
which uses ardunio-cli

Yes I have also read about the Dynamic connections bug.

But I think this will just be a alternative to do

surely it have enough memory for that application
even a pic18f4550 have 32KB flash and 2KB ram
and that worked super as a midi2uart
until I did buy a teensy 4 that could also have the synth part

I would ask the threadstarter
what specific devices are you gonna use?
Just to clarify some things
