miniAtmegatron / Re: Odytron for miniAtmeagtron
« Last post by paulsoulsby on March 27, 2017, 08:14:28 AM »
Yes you can find the code that does that at the bottom of MinOdyEngine.cpp (v2.6). Just delete the following:

Code: [Select]
if(sequencer_->getStep()==15 && sequencer_->getPattern()!=0)
I should have really wrapped that in the conditional if for Xmas code!

You'll need to use all the V2.6 libs together, replacing just one lib will probably not compile. Let me know if you still get any compile errors.

The pots control identical functions to the normal miniAtmegatron software apart from:  Distortion controls Osc 1 pitch offset and Phaser controls Osc 2 pitch offset.

The functions are also mapped to identical features in the Ody engine ( I think cyan only only controls portamento, as there is no wave crusher).

I'll definitely have the final version of Odytron for mini uploaded by the end of this month, with all the Xmas stuff removed and extra MIDI CCs added.

Hey Paul, hey everyone, first post!

Received the two atmegatron mini I ordered in the mail yesterday, soldered them and instantly blown away! They're really awesome, and sound great! :D

I built one into its enclosure and left the other one open for hacking. I then downloaded the libs (2.5 and 2.6), currently running 2.6 and flashed the odytron software. I was able to un-xmas the sequencer by setting the sequencer variable back to MINI, but have a question: when the odytron is flashed, the sequencer keeps chaining all pattern in a row, not looping. How do I get it to work like on the miniatmegatron, cycling 16 steps?

When I replace the 2.6 lib sequencer code (4 files) with the old one (2.5), I get compiler errors.

Also, any hint on what the pots do in odytron mode?

Any help appreciated! Thanks!  :D

Hi Paul,

That would be great, if you could email it to me I'll let you know how I get on.

I've made some updates to the MIDI handling since the official version of the Odytron.  Would you like to try a new .hex file if I email it to you?  If it fixes the issue, I'll release it as a new version.

Alternatively, you can use Easy Uploader to save the patches, and let me know which one is causing the issues and I'll try and recreate the issue.

Odytron / glitchy response when sending MODULATION messages
« Last post by shabbee on March 20, 2017, 05:07:24 PM »
Hi Paul,

I wonder if you have noticed when sending MOD messages over MIDI to ODYTRON that the response is rather glitchy as the MOD level increases? The behaviour is the same as increasing the LFO MOD depth using the value slider suggesting it's not a MIDI issue. In addition, sending a lot of MOD data can cause the value LED to light up and remain lit but this is quite intermittent.

I have uploaded the new firmware but has made no difference.

Just popping in here to say that I recommend trying out the Odytron port for miniAt. It sounds amazing!!
Oscitron / Re: pitch calibration question

Hey Paul,

I don't have a voltmeter, I worked it out through the CV.OCD manual. Here's what the manual says:

When CV.OCD is sending out a musical pitch CV, it uses a 1 Volt/Octave standard and has a range of 8 Octaves. Middle C (MIDI note 60) is set at 3 volts, so the output range is approximately MIDI note 24 (C1) to 120 (C9)
 C1 (MIDI 24) = 0V
 C2 (MIDI 36) = 1V
 C3 (MIDI 48) = 2V
 C4 (MIDI 60) = 3V
 C5 (MIDI 72) = 4V
 C6 (MIDI 84) = 5V
 C7 (MIDI 96) = 6V
 C8 (MIDI 108) = 7V
 C9 (MIDI 120) = 8V

I worked it out as best I could (I'm no math whiz) from there.

I think I was using the sine wave, the default wave after turning on the system (right?).

Did you check the voltage with a volt meter, or did you work it out via the CV.OCD manual?  It sounds like there's a discrepancy somewhere and the CV.OCD is an octave out.  Coarse = 9, should def produce 440Hz. 
Can I also check you're using a square or other basic wave on the Osci, not one of the waves with harmonics that can sound like it's an octave up.  Captured waves can also sound like they're an octave up (depending on settings and audio source).
It's not a disaster if it's an octave out anyway.  As you have done, you can use the coarse pitch to correct. It will mean the CV range is only 4 octaves rather than 5 though.

Here's what I found working with the tools at my disposal, Paul. I am using a CV.OCD MIDI>CV device from my DAW. CV.OCD is like the beatstep, C1(MIDI 24)=0V. So I sent a D#2(MIDI 39)=1.25V signal for the first calibration, and a A4(MIDI 69)= 3.75V signal for the second. With the function knob on coarse and the value knob on 9, the pitch was A5. the pitch is A4 on a value of 6. I don't know if I was doing something wrong, but at least I can play the oscitron in tune now.

hope this info helps. please let me know if you think i was doing anything wrong in the process listed above. Thanks Paul.

Thank you, Paul! I'll review the video and try it out. Let you know if I fail and have further questions!  ;)

I really appreciate your prompt support in this matter. Have a good one!
