Odytron / odytron 1.3v
« Last post by Paul Price on February 17, 2018, 03:49:26 PM »
got the atmegatron and using the easyuploader easily going through nearly all of the synth downloads available apart from the odytron 1.3v which i can't seem to download off the downloads webpage as a list of numbers and letters appear and not giving me the download option..... :(

Hey,

thx :D
The song is stored in the hardware sequencer, which uses a few more instruments of various devices, which I then recorded live.

Quote
I'm not entirely sure whether the lead in a middle section was a processed Atmega or something else though.

Part C is definitely the SID part. But there, the phase of the two channels could be better. The SID instrument is a sync + ring modulation.
Part D starts with Atmegatron lead...,  Part b/B starts with odytron rhythm. The Arps are all from a second SID board.

And though the notes seemed at first to be missing, it worked as a nice effect when D came back later.

I think I wanted to let a little air there ;)

I've been dragging my feet on a song lately.... Hopefully I'll finish the song soon so I can put it online.

I'm curious, I want to hear it ;)

I laid out a structure with the bass line and then tried to put other stuff on top.

That's fine. I think I always start with the beats (which could also be a bit more varied) and then I work on the bass and back to the beats.
It often happens to me that some parts are a bit too stiff, a little more variation could make the thing even more lively. I forget to granulate the parts even more. .. and what I unfortunately do not use enough are my two old speech synthesizers!

Greetings !

here is my first tune, where the odytron sets the rhythm and Atmegatron plays the melody - regardless of any other instruments I used for that song (SID, 303, virus, p2k).

That's pretty good!  Very classic chip sound plus more.  I'm not entirely sure whether the lead in a middle section was a processed Atmega or something else though.  It's, um ...  Let's see.  The song structure seems like the patterns are laid out as "AAbBBCCDDEEFFFfDDDd".  The lead in part C is what I'm not sure about.  Overall though, I think it went together well except a couple spots which stood out to me.  I found the transition from "A" to "b" a bit odd, and also what seemed like missing notes in the melody of part D, but mostly I thought it was very good.  And though the notes seemed at first to be missing, it worked as a nice effect when D came back later.

I've been dragging my feet on a song lately.  I have most of it ready but still need to record the melody tracks more carefully.  Aside from drums, the entire thing is made using what I call the "Atmegabrute"...  a.k.a. an Atmegatron routed into a Microbrute, then through a KP3 for delay.  Same midi signal sent to Atmegatron and Microbrute, so it effectively uses the Atmegatron as an oscillator on the Microbrute, running through all the same envelopes and filters and such.  It gives me a nice 8-bit tone but with extra bite and an easier interface for shaping the sound.  Hopefully I'll finish the song soon so I can put it online.

Oh, um, the song structure thing comes to mind largely because it's a thing I'm bad at and my current in-progress song is largely to try to get better at it.  I laid out a structure with the bass line and then tried to put other stuff on top.  The bass goes "intro ABAC bridge ABAC end", and I'm still working out the melodies.

*Edit* Apparently it was Microsoft edge downloading the files I some strange format. Tried it on chrome and now everything works perfectly again strings and all!

I tried uploading the strings software at first which didn't seem to work. I turned the programmer switch off and took the cable out and de powered the unit. Now when I plug the power cable in nothing lights up. I tried uploading the default software and that doesn't seem to work either.

miniAtmegatron / Re: Is Miniatmegatron open source?
« Last post by paulsoulsby on January 28, 2018, 10:50:11 PM »
I would much prefer a simple 7 segment display controlled by a shift register. I could wire up a shift register to a display, but I can't program these, so I guess I will keep trying. thanks

The main issue would be that the a shift register requires 3 data lines, but there's only 2 available for the value LED.  You could make use of pins 0 or 1 if you don't intend on using MIDI.  It would take some careful programming to make sure that the time taken shifting of data to the display didn't halt the playout of the sequencer.
Possibly a simpler alternative would be to put a MIDI connection on the front panel (using mini-jack wiring).  Then control it from an external MIDI controller, or even use the Touch OSC or Lemur templates for a graphical interface.  All parameters are available on MIDI CCs.

hi Paul,

I was able to connect it to an amp and have some fun. Looks like the only thing I messed up is the direction on the A/B switch. I can fix that. I had the manual out and the quick start page. I was ready to test some specific items. :) I can't count the green blinks, or green and yellow, I can't do it. I also don't know if the items roll over or stop when they get to the min or max value. If it stops I should be able to click minus a bunch of times and know I'm at 0, then click + the number you want to select. If it wraps, or rolls over I don't know how to use it. I would much prefer a simple 7 segment display controlled by a shift register. I could wire up a shift register to a display, but I can't program these, so I guess I will keep trying. thanks

I'm such a nit wit, I never even thought to look for it on your website. Like duh...  :p

I got the code uploaded... It was, uh, easy. :) I now have a blue LED on the left and a green/red flashing led on the right. Yippy :D They are so bright! I need to swap out some resistors.

I used the version 2 of the code, not sure if it matters, and if it does, what it effects. I need to connect it to an amp and print the instructions, and have some fun. Thanks for again for your help!
