Atmegatron / Re: Any more Atmegatrons?
« Last post by paulsoulsby on February 12, 2019, 02:00:21 PM »
Hi - I'm still working away on ATX.  Apologies for going silent, there's just so much to do.  To confirm the new ATX range will consist of:
Atmegatron II - 2 Atmegatrons + new powerful control interface
Atmultitron - 8 Atmegatrons, analogue filter, analogue VCA + control interface + keybed + joystick
Separate Eurorack modules of Atmegatron, Filter, VCA, Controller (required for control of other modules), possibly joystick/keybed interface and other IO modules.

The idea of ATX is that it's expandable, so 1 controller can control upto 8 synths and 8 fx cards (filters, VCAs, fx etc).

Let me know if you want any more info (apart from price, still can't do that yet I'm afraid!)
Upload instructions are here:
or video here:

Lemur and Ctrlr are just methods of controlling the miniAtmegatron via CC messages.  They aren't VSTs, but you can control it from your DAW over USB MIDI.  All parameters are available on CCs.

The main change was the RGB LED, which has different pin-outs. You'll see issue2 or 3 written on the PCB.  If the LED colours look wrong, just try the other one. It won't damage the board.

Hey all/Paul
I accidentally uploaded a blank arduino sketch and now my Oscitron doesn't work... is there a place to get the arduino sketch to reupload?

Where can we see the plans for 2019, Paul? I take it that there are going to be new Atmegatrons next year, right?
Hi, Im currently waiting for the courier with my miniAtmegatron, and im reading the manuals, and watching the tutorials, but have some questions regarding the software,

how do i uploaded or make use of it ?
when installed those it give me a type of controller, editor or vst? (like the lemur or Ctrlr)
and, what is the difference with 2PCB and 3PCB ?

thanks in advance :D

I made another thing.  Just a quick sketch, really, but it's a NES-styled 8-bit tune so it's kind of relevant.

I mostly made it to get the idea written down, so I can go back and finish it later.  But then the Smash Ultimate trailer came out, so I tried their thing with my thing...  and it fits!

Nothing fancy, no effects -- just square waves, some vibrato, and drums.  I find I really like prototyping songs that way.  It keeps the emphasis on melodic composition instead of patch design, and a square wave has a rich set of harmonics so I can really hear which notes fit together and which don't.
Software technical support / Re: Playing duophonically with controller keyboard

Just had a look at the code - looks like it is only monophonic.  I wrote it so long ago I'd forgotten how it worked!  I'm pretty sure the first poly code i wrote was Odytron (which came after Duotron).  I guess it might be possible to update it.  If I transfer it to the new Atx system, I'll try and do a new version for the Atmegatron too.

Hi - that range of Atmegas wouldn't be compatible without significant changes to the code and schematic.  Think it would be possible though, with the necessary changes.
