emkay Posted January 24, 2009 Share Posted January 24, 2009 What to say? Hardsynth methode gets better when the timing is more precise..... but the emulation gets more loose. To adjust the sound in the emulation results again in some wrong sounds on the real thing. But it is still good for a demonstration. Listen to sounds you never may have heared before from POKEY. Particular the synth voice in the upper midrange: clear and without clicks or else... and a nice reverb is still enhancing it. Mostly the bass sounds suffer by the different timings.. 4xst.zip Quote Link to comment Share on other sites More sharing options...

Tezz Posted January 24, 2009 Share Posted January 24, 2009 It's an interesting example Emkay, can you explain with some further details what you did to create the mp3 example Quote Link to comment Share on other sites More sharing options...

I meant the technical details of what you tweaked in the emulation to produce the example recorded in the mp3, or was it recorded from the real hardware?

Heaven/TQA Posted January 24, 2009 Share Posted January 24, 2009 suprised that it sounds so good! well done! Quote Link to comment Share on other sites More sharing options...
athleos Posted January 25, 2009 Share Posted January 25, 2009 this was done in RMT? very cool sound. Quote Link to comment Share on other sites More sharing options...
emkay Posted January 25, 2009 Author Share Posted January 25, 2009 this was done in RMT? very cool sound. Yes, it's done with RMT... If only the emulation was correct Another test... with 4channel hardsynth at 4x speed: 4chtst.zip Quote Link to comment Share on other sites More sharing options...
xlent Posted January 25, 2009 Share Posted January 25, 2009 Another test... with 4channel hardsynth at 4x speed: Atari has only ONE Pokey. This 8channel hardsynth tune for "Mutant'ari". Quote Link to comment Share on other sites More sharing options...
emkay Posted January 25, 2009 Author Share Posted January 25, 2009 Another test... with 4channel hardsynth at 4x speed: Atari has only ONE Pokey. This 8channel hardsynth tune for "Mutant'ari". OK. Just give me a tracker with full POKEY support and I'll give it a try. POKEY cannot replay Music with 4 channels... alike how fast you update the generators. At least some tracker with 4x speed for one hardsynth channel, the 2nd channel may be handled fast enough at single(or double) speed and one digi channel for the deep sounds... We could use this music for "ingame" then... But, until we don't have this, I think it is better to do examples with the available stuff.

emkay Posted January 25, 2009 Author Share Posted January 25, 2009 Nontheless... One POKEY can play 2 of this channels, if not even better, after the emulation is corrected to have the ability of adjusting the sounds 100% POKEY like.

emkay Posted January 29, 2009 Author Share Posted January 29, 2009 The tune suffers heavily by the different timing there. Particular with the bass tones (as always).... But let's have alook at the waveforms, recorded from the real thing: I wonder if someone really recognizes what's going on here. Just some term: Multi waveforms. They are not caused by any heavy CPU load. They are caused by a timed programming of a generator and the additional "Filter" at 15kHz... And I really wonder, why this fact that we could call the "filter" of POKEY an LFO is denied for a long timespan of more than 30 years.. And, what makes me even more wondering is the fact that still (almost) NO one is caring about this fact.... Quote Link to comment Share on other sites More sharing options...
+Stephen Posted January 29, 2009 Share Posted January 29, 2009 Really cool demo emkay - that's quite some low bass at the 17 second mark. Stephen Anderson Quote Link to comment Share on other sites More sharing options...
emkay Posted January 30, 2009 Author Share Posted January 30, 2009 Two short recordings of the 2nd tune. You may recognize that the low melodic sounds turn into some digital noise, while the high sounds seem more accurate on the real thing. (lower and higher notes fit better together and the high sounds are even more stable) The low sounds simply need a different timing than the emulation. 7890.zip Quote Link to comment Share on other sites More sharing options...

And, what makes me even more wondering is the fact that still (almost) NO one is caring about this fact.... that is a very interesting observation. are you saying that the "filter" is in fact, an LFO modulating the pulse width of the square waves? in my short experience so far with the POKEY, i've been curious about this very thing. to me, it actually does sound more like PWM than a filter... cool stuff!

Heaven/TQA Posted January 31, 2009 Share Posted January 31, 2009 the mp3s sound good... some kind of fresh as not very pokey like? Quote Link to comment Share on other sites More sharing options...
