ABBUC hardware contest entry: Pokeymax

Recommended Posts

Any updates on this project?


Id like to say yes but it wouldnt be true!

I made a prototype gtia and 6502 to match. I had some issues with antic though.

For now Im focusing on my other projects but Im sure Ill get back to this one again at some point.

Is it possible to have output pins for each of the 4 channels?

That would allow focused external manipulation.

There are actually 4 outputs: 3 on header and the 4th to the pokey audio output. Could make a mono core with a channel to each if you like?

I mean the following, having in mind an example for only 1 Pokey (mono audio).

 

The first post says:

Features: Pins for 3 audio outputs (left channel / right channel / mixed).

 

Then looking the layout, and for a mono audio: Left = Right = Mixed:

But the Pokey contains 4 audio channels with separate frequency, noise and voice level controls (AU1, AU2, AU3, AU4). I guess the output signal is just the combination of the 4 channels: Mixed = AU1 + AU2 + AU3 + AU4.

So, besides the current 3 output Pins (left / right / mixed), is it possible a PCB layout with 7 output Pins?: Left, Right, Mixed, AU1, AU2, AU3, AU4.

 

Or as you said, having already 4 outputs with a mono core, the following configuration for example:

Left = AU1

Right = AU2

Mixed = AU3

A4 = AU4

So in that scenario would be possible to have an individual Pin for each of the 4 channels.

 

I mean, if it's possible to have each channel in a Pin, it would be great, because that will allow to recreate for the first time a real Stereo sound, starting from a mono software. For example AU1 + AU2 to the left speaker and AU3 + AU4 to the right speaker, or some good combination.

Or if one is going to use it to produce music in a studio setting, it would be extremely handy if each channel has a separate output. You could route channel 1 to a flanger, channel 2 to a reverb, etc.... Otherwise you have to record each channel separately with the rest muted. And in a live setting that's not even possible.
