Thanks! smiley

Now for some tinkering again!

Thanks for a great build!

I've made my own shield based on your v4 design and have just built a SIDaster with a pulled MOS 6581 - supposedly working.
I'm using an Leonardo at the moment and is feeding VCC 12 v and there's no blue smoke or heat  smiley-cool

However, I have no MIDI keyboard at home right now and I just want to verify that the build is sane...

I have connected a small speaker to SL1 and I'm not looking for great sound here, only for test purposes. (I can admit that I haven't ascertain what the line level is at SL1...)

In the loop() I'm trying to use synth_on() with various int values but no joy, nor does MIDI.sendNoteOn(42,127,1) generate anything...

Any help would be great here!
I should be able to get my hands on a cheapo MIDI controller soon since I'm reluctant to connect my Roland Guitar MIDI kit thru the SIDaster and then wire it to my Linn stereo BEFORE initial tests.
I have no oscilloscope at home either so I can't measure the pins on SL1.
SL2 is closed with a jumper.

Many thanks in advance!
3  Using Arduino / Audio / MOS8364 Paula on: January 09, 2013, 05:02:23 pm
I've been searching for info how to use an MOS8364 Paula chip from an old Amiga in order to create a hardware tracker player and I found an old thread here which sadly resulted in failure to find the pinout to the MOS8364.
However, now I have found the datasheets!

I thought of this as I was connecting a SID chip to an Arduino Uno in order to play chip-tunes...

Is this something that tickles anyone else out there?
