Fluxamasynth alternate MIDI input

Post by odbasta »

Heyo,

I see there is an alternate input for MIDI on the Fluxamasynth shield. It looks like digital input 4 from the picture (can't find a schematic for the shield).

Anyway, do you guys have code to enable that on the Arduino? Is it just a bit-banged output from there?

It would be nice to use this input because it frees up the serial port for debugging on the main board.

Thanks!!

Check out Arduino's SoftSerial: http://www.arduino.cc/en/Reference/SoftwareSerial You have to change the Fluxamasynth library though - it has the hardware serial hard coded...

Just in case you missed the announcement above - here's the SoftwareSerial Library

Hello,
Is there a copy available of the original/old Fluxamasynth library from ~ 2011?
I've seen references/links to [http]:[//]wiki[.]moderndevice[.]com/pmwiki.php?n=MD.ListMethods .
I'm guessing that when the new modules were released the old library was made obsolete.

Did this library include these files?
#include <NewSoftMIDI.h>
#include <Fluxamasynth_NSS.h>
#include <NewSoftSerial.h>

I'm adding a MIDI input to the Fluxamasynth-32, and an old post by Mittwoch on Ardublog
has an example I'm examining as a model:

Thanks,
Donald.

p.s. I can't post links so I've used these pseudo-urls.

I'll take a look at the project. Did you try to dig through the Github repo - some - but not all - older versions are probably there. Feel free to post some code if you want and I'll try to get it going.

Hi...I have needed to assemble a DB synth for quite a while yet finding a card has put me off, and it would seem that the China source has evaporated at this point. Much obliged for finding a decent elective Smile

Just completed the process of perusing the first GM Midi Mod string (s) which I think I investigated for some time back. A genuine enthusiast of XG midi and despite the fact that the SAM chip isn't exactly equivalent to a DB60 it would seem that it's the nearest I'll get without burning through a lot of money.

HadriaGuy,

We hope you'll have fun with the chip - it's very capable.

Due to the low impedance of the the Arduino Uno serial port (1k ohm) you should use a different serial port - Arduino Mega or other microcontroller for intercepting the midi in - if you're going in that direction.

Our optoisolator doesn't output enough current to make the Arduino Uno RX input viable.
