amazing... I managed to remove the references to the GUI and compile it on Linux!!
Basically I've added #include <cstdlib> at the beginning, I've downloaded the SDK from https://github.com/steinbergmedia/vst3sdk (there is the link to steinberg's website), and I've followed the help there: http://teragonaudio.com/article/Buildin … Linux.html

Then I've run those commands:
g++ -fPIC -c -I/tmp/VST_SDK/VST2_SDK -D__cdecl="" chipwave.cpp
g++ -shared  -o chipwave.so *.o

and got the chipwave.so VST in Linux format!

And the best part is it's working in Ardour (which cannot load VST in windows format, unfortunately, but as a workaround I was using the Festige app which can load windows VST in .dll and it can be rerouted to Ardour using Jack)

I've put my binary there if someone is interested: http://garvalf.online.fr/var/upload/temp/chipwave.so

Shiru, this ChipWave VST is indeed very interesting! I like it very much!

I've begun a short tune with it, it's a WIP yet, but it's only using your synth, no other one (but some reverb and eq effects): https://instaud.io/2iSe

Hi, sorry for the answering delay, haven't been on the forum for a few days...
For adding a library, there is an option in "sketches" => include library => add zip library, but I suppose what you did was correct. You should see the new library in the menu anyway, in "contributed libraries".

1.6.4 is not the most recent version but anyway, most if not all arduino versions should work. I've just tried with 1.6.5 and it's ok for me.

When I upload a sketch, I must unplug the midi cable from the garvuino, otherwise it won't upload (anyway there should be an error when trying to do so with a midi cable plugged).
When I play a note, the "rx" led is blinking. When I push the switch button, there is a sound, and the blue led (on the board) is blinking as well. Is it the same for you?

Can you try uploading the sid_player sketch? is there sound with it?

more fun with this engine...

I've added a knob and and I can slowdown the replay of the song:

  current_speed = constrain(map(knob_value,0,1023, 2, 20),2, 20);
/.../
  parser_sync=song_speed*(current_speed/2);

I've just pushed on the qchan repositories a few songs from AtariTufty's excellent album 1-bit mechanistic: https://github.com/farvardin/garvuino/t … uino_qchan

I hadn't the source for them but I forgot beepola's excellent feature to import / rip songs from .tap files.

And it sounds pretty well on the Arduino, especially Robotix!

New engines, very impressive!

Someone I know has found a way to compile 1tracker for 64 bit. He made a (linux) script to fix this. Basically it retrieves the original angelscript code, change a few words, and recompile everything (because I think some code was precompiled for 32bit in angelscript. How could be the right way to fix this upstream? Through a patch or a new makefile? (_x86 should be replaced by _x64 in the makefile for example)

Oh, I'm glad then. I feared it could be broken during shipping, or the package would be too thick.

For flashing, you only need to unplug MIDI from the board (or the synth) otherwise it won't transfer. I was thinking to add an extra jumper which would have been easier to remove than the midi plug, but there already too many jumpers on this board! I have a midi connector with double female input and 2 midi cable, like this one https://www.ebay.fr/itm/5-Pin-Din-MIDI- … SwYwJaQj5z this way it's easier to unplug when I'm working on a sketch and it won't tire my equipment.

For Mozzi, any sketch from their website should work (except hifi of course), as I've used standard pin 9 for output, so you can try them. There aren't many for using with MIDI unfortunately. On my github there are a few I've adapted or copied from somewhere else, like from CheapSynth project: https://github.com/farvardin/garvuino/t … ches/mozzi (lowpassfilter + midi is not working yet). I want to do more!
Their demos, like low pass filter, FM synth etc are impressives!

There are some extra PIN (both input and output) on the board you can use, for example to add sensors or potentiometer (but you'll need to code this or adapt some code from somewhere else). I also plan to add some more examples because I like those cheap synth sounds! I already have some potentiometer and sensors sketches for other projects, I need to adapt them to Mozzi!

ok it has been sent now! I've removed the brass stands, and put it in a little plastic bag, don't miss them, you don't even need a screwdriver to install them again.
I've already flashed the arduino with a 1-bit tune (phaser1 from MR BEEP), it sounds great!

I've received the missing parts and now I have a few more boards...

I've made a shop on Etsy for this: https://www.etsy.com/fr/listing/581873069/
You can order it there, or send me a message on http://garvalf.online.fr/contact_form.php

I see there is this project: https://playground.arduino.cc/Code/ArduZ80
Don't know if it's possible to use the other beeper engines on it!

It's also possible to drive a real z80 from arduino: http://baltazarstudios.com/arduino-zilog-z80/
