Trying to make some PoKEY music!

strange things are happening inside of my head

Creating impossible sounds is so much fun

Not impossible but a very nice arrangement.

Yeah, objectively these sounds are possible, since they're right there, I meant through conventional means, not something possible, especially not without any filters. ;) 
 

Having added support to use the Two-Tone Filter in RMT has to be one of the few things that may turn into incredible stuff once we come with a better hang of it.

That said, I am aware the way I did add the feature is... something that needs a better execution in the first place.

At least, the proof of concept is there, and it is still fully usable, just a bit awkward to set up. :D 

 

Something that gets even greater with it is when the High Pass Filter is layered on top of it, that modulates into really interesting sounds.

Of course. 

The problem always was to get a row of notes for melodic correctness, which you managed nicely by patching RMT. 

 

I wished I had the time to do that, back then.

Thanks, I have a lot of fun with this.
Even if I don't have as much free time as I wish, I like to spend it into this lately, I learn new things every day, and I also learn to code as the same time, so more to enjoy.

I was bored so I hacked the Draconus music driver for absolutely no reason lol

 

 

draconus.obx 2.92 kB · 1 download

I never had any problem with the used basses in the original tune, as it was somehow built on them .  I always missed the punchy beat. 

But truely sounds more chippy now :)

I'm trying to make an audio cue in RMT, and I would like to know how to change the waveforms?

Instrument Screen -> Distortion?

For example, Distortion A is square wave, the other ones are either noises or bass tones.

Just messing around a little with modulation in a sketch tune.

Testing my improved Patch16 driver with some impossible sounds using the high pass filter modulation.

Patch16 driver so far: tracker.obx

Simply drop it in the latest RMT 1.31 release 'RMT Binaries' folder, still not all touched up but the improvements really made the timing much tighter, the Filter modulation really becomes under control with my "Get AUDCTL Early" cheat code (lol).

Here's my .rmt if anyone wants to play with it, or maybe add more to it if you feel like it :D sketch 66 v3.rmt

Just for fun here's an oscilloscope visualisation of the modulation of this test tune, using the still in the work improve patch16-2 hack:

Progress for that one is getting very well, I found new improvements, and added brand new 16-bit tables, but I'll save this for another day since it's still incomplete right now :D 

Here's a binary I built specifically using the ASM code I am editing, but soon I'll add the full changes to the RMT export formats in a future update for it.

sketch 66 p16-2.obx

The timing is so good this should sound identical on hardware, and even in PAL mode the pulses timing is very constant, this makes me really happy.

Hello guys

 

How do I start .obx files again?  Atari800MacX doesn't seem to understand what to do with it (I get the selftest without BASIC and READY with BASIC).

 

Sincerely

Just rename them to .xex

Hello MrFish

 

Thanks!  I seem to remember that I downloaded a .obx file a couple of days that did work as an .obx either and after I renamed int to .xex, it still didn't.  Can't seem to remember which file that was.

 

Sincerely

Should be fine, as that's all they are is binary load files. I don't use Atari800MacX anymore though (using Altirra); so maybe it's using some other extension. Try .exe, or whatever extension is used by all your other Atari executables you use with it.

Hello MrFish

 

It runs just fine after I renamed Vin's last file to .obx

Oh brother, I guess my brain needs an update.  I renamed it to .xex of course.

That does not sound like POKEY ... well done!

ah the point is this how pokey sounds, it's quite capable and it's nice to see it being used in this way.

That's precisely what motivates me going further... there's so much that could be done but it's almost never explored, so experimenting and trying to find out is a lot of fun!

 

In the mean time, Triangle

You can guess what this is supposed to mean until later tonight :D
