You mean "one" is enough? Just like an omen? Standing for "one" POKEY is enough?

I put this tune in here, even though it is a "standard" 4channel tune.

It uses some pokey frequency arpeggios, and sometimes 16 bit are used when the note has to get a bit deeper...
The tune is still 4 channels even if 16 bit is used.
Listen to the different colours of the sounds :)

the first instrument was done by simply using a small vibrato on the "A" generator
Now it is changed to Pokey clocking arpeggio... and some volume chages have been done.

Some "sweoooo" FX are still missing from the original.

my girlfriend has been listening to 'the postal service' recently and there's a few songs on the album that sound like they belong on a highscore table.

[url="http://www.youtube.com/watch?v=hMOkfI7wCrI"]http://www.youtube.com/watch?v=hMOkfI7wCrI[/url] - such great heights
[url="http://www.youtube.com/watch?v=FAPy64IgG58"]http://www.youtube.com/watch?v=FAPy64IgG58[/url] - sleeping in

You should give one of those a go - I'm having a go, but can't quite get the feel right

A FX soundchip doing a known tune in a more rhythmic way ;)

Some tunes work better at 64khz clocking, some with 15khz based sounds...
Again 64kHz clocking with some 1.79Mhz additions...
It makes Pokey playing at a wider range of frequency. And if you find "Pokey yelling his balls of "(quote from Sack :) ) please tell me ;)

Some softer sounds ... I guess.

This time some 1.79Mhz is used and for removing cancelling of some sounds, Hardsynth like phase correction is used. But this isn't 100% working correct, because of the know timing issues and different waveforms bult by the emulation.

For bass tones mostly gen "C" or "E" is used. In the patched version of RMT is use, they are not accessible. Gen "2" is more stable but it sounds very hard. RMT seems to handle gen 2 a bit wrong, but it works with that tune ;)

IF you want good balanced sounds in low and high ranges, you have to stick to 3 channels. But this thread ia about 4 channels :)

Well, haven't much time lately, but hey...

Here's some nice piece of noise.

The song is played one semi-tone higher than sack's one (just to avoid badnotes in bass).

Made in RMT hacked "some other way", not compatible with mux's one (not finished yet).

Enjoy Plastic pop! :D

Very nice - I see why you named it Plastic. The bends(slides) sound great. Is there any way to make these RMT files play at the correct speed on an NTSC machine? I assume they would have to be somehow converted as this is all driven off the VBI. Would it be possible to have a selectable playback speed?

As said before, gen 2 can be much better tuned than C or E..... but you need "special" tunes for this ;)


One note and two pitches away from the standard RMT notation it sound like this:

[quote name='miker' post='1792477' date='Mon Jul 13, 2009 5:51 PM']Interesting, but i rather stick with "conventional" Atari-basses.[/quote]

I unterstand why. Gen 2 is simply too hard for common bass sounds...

On the other hand, gen C and E always sound a bit off and they have stability problems.

The most stable bass notes we get with 16 bit gen A....

The best solution for a 4 channel tune is the usage of a high clocked 16 bit channel. You can use deep note for the bass and when usinng gen 8 on the 1st channel, you can create various percussions.
So you still have 2 voices at 64 khz left and one of them can be switched to 1.79mhz , if needed.

A horse for a kingdom .... or vice versa ;)

A good working 16 bit channel would be enough ;)

At least some other gen 2 usage :ponder:

To make it somehow completed, here some tuned that I have already posted in the past, but they may fit better into this thread

Listening to this one, gives the imagination of a full possible game :)
