==> ARDUTOUCH KITS ARE AVAILABLE at CornfieldElectronics.com <== ArduTouch is an Arduino-compatible music synthesizer kit with a built-in touch keyboard, and with built-in speaker/amplifier. Build it, and it works! Way low cost (currently $30.) It comes pre-programmed with a music synthesizer (called "Thick") that makes really nice sounds and music and noise. Other diverse synthesizers available at CornfieldElectronics.com . An ArduTouch Arduino library is available for programming in more super nice synthesizer features. The ArduTouch Arduino library comes with many way cool example synthesizer sketches that also serve as a tutorial for making your own ArduTouch synthesizers (which are Arduino sketches). For those who want to learn more, the documentation teaches the basics of Digital Signal Processing for audio generation (with more documentation to come)).

ardutouch's Issues

Beatitude too big?

It seems using a recent Arduino (1.8.5) and avr base library (1.6.20) it is not possible to compile and use the Beatitude example.

Arduino complains that it is too big:

Sketch uses 33780 bytes (104%) of program storage space. Maximum is 32256 bytes.
Global variables use 735 bytes (35%) of dynamic memory, leaving 1313 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Arduino/Genuino Uno.

Or is there anything else I'm missing?

Call setAttack() on OneVoxSynth setup()

Hello Mitch and thank you for this nice librairie !
I try to create my own synth sketch. I use the OneSynthVox class. I want to set attack on the creation of the objet. So i called the setAttack() method inside the setup() method, it doesn't work. But it work's inside evHandler() method. What is the best way to get it work ?

#include "ArduTouch.h"

set_baud_rate( 115200 )

class mysynth : public OneVoxSynth
{
public:
void setup()
{
OneVoxSynth::setup();
setAttack(100); // it doesn't work
}

boolean evHandler( obEvent e ) // event handler
{
switch ( e.type() )
{
case KEY_DOWN: // a key has been pressed
{
setAttack(100); // it work
return true; // KEY_DOWN event was handled
}
default:
return false; // ignore all other events
}
} synth ;

void setup()
{
ardutouch_setup( &synth );
}

void loop()
{
ardutouch_loop();
}

Midi addon

I want to make a midi adapter.
If someone wants to colaburate, just texts add to this tread or text me.
Planned Features (will see what is possible):

• Pure clock signal input for sync with eurorack.
• Midi Input TRS (audio Jack Format) to play the synth with an external midi Keyboard. Like Midi Secs
• Midi notes play the Synth.
• Midi Notes change the parametes of the potentiometers.
• Midi clock signal syncs the whole speed (LFO....) notes pressed.
• (maybe) different notes trigger different sync parameters.
• (maybe) Midi Notes change more parameters in the synth.
• (maybe) changing midi channels on Hardware not just in IDE.

My questions are:

• Does anyone have a good Idea, which are the best pins to steal, for the input signal?
• Where should the clock be feed into?
• What should the Mapping be aka what kind of note on which Midi channel should trigger waht internal Function(filter, LFO, DSR)?

I´ll prepare now and keep posted here if something changes and it works :).

Arduino IDE error

Please help! In all the example sketches, I keep getting this error:

Can't upload sketches in Arduino IDE 1.8.13

Hello!

My friend and I each have seperate ArdoTouchs, our own USB serial adaptors from Cornfield (for the U.Do.IT.Duino), and our own computers. He just tried to flash a new .ino file onto his ArduTouch following the instructions from both his Mac and his Windows computer, and told me it wasn't working. So on my own, I set everything up on my Linux box and encountered exactly the same error when uploading:

Sketch uses 25210 bytes (78%) of program storage space. Maximum is 32256 bytes. Global variables use 799 bytes (39%) of dynamic memory, leaving 1249 bytes for local variables. Maximum is 2048 bytes. avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding

Of course it times out after 10 tries. Since the same problem occurs with multiple versions of the same hardware, on different computers and in every OS, I assume there is something wrong with how the latest Arduino IDE is set up? Or is there some step or troubleshooting step that might be added to the .pdf?

Include sch/brd source files in repository?

It seems like everything else is nicely presented and included except the actual schematic and board file. :)

'void ThickSynth::setup()' cannot be overloaded - Arduino 1.8.6 or newer

I get 'void ThickSynth::setup()' cannot be overloaded on Arduino 1.8.6 or 1.8.7. I have tried Linux and Windows versions, same error. I also get the same error for different ArduTouch projects.

It works fine on 1.8.5, so I guess that's the immediate mitigation.

I believe it might be related to: arduino/arduino-builder#292
