What's this then?
Re: What's this then?
LOL yes, we're entering 6 channel territory
Presently, exactly like you've said, the only commercial option is to get hold of either a zxpand-ay plus a mr-x interface (with updated GAL) or use 2 mr-x interfaces, one of which needs an updated GAL to alter the port assignments.
I have a homebrew turbo board which will head off to Poland at some point but this uses the a4 line to select the AY chips so no updated code is needed - the 'standard' 1f/df & 0f/cf addresses are retained.
With 2 AY boards you need 2 cables. My Turbo board mod only needs one as the outputs from the twin chips are mixed and sent down the normal path to the stereo output.
Fun

I have lost the plot . Blink and we jump from one amazing "AY" to a double "AY"!!!!
-------------------------
Haaaaaaahahahah, yes!
> So I take it that the hardware requirements are two "AY" sound generators (ZXpand+"AY") + (MrX with new GAL) or (ZXpand+double "AY") or (two MrX one with the new GAL)...
Also are the three channels from each "AY" being separated (to make a total of 6 channels) and going to a mixer, or are all output channels being connected together to create a mono channel, or are the two "AY"'s feeding as a 3 + 3 stereo output?
----------------------------
It is 3 + 3 stereo output. Normally it's one channel on the left, one inside, and one channel on the right hand side.
In this case we have the same but...... twice.
If anybody's interested, I can record more songs to give to the people idea of our experiments.
I think it sounds interesting enough to get:
- ZXpand + ZXpand_AY + Mr-X
or
- if one has any other diskdrive - Mr-X + Mr-X (with a new GAL chip).
Of course the problem is to mix entire stuff but I noticed - somehow ZXpand-AY and Mr-X have almost the same level of loudness, so actually no further steps are required - except putting all the audio into any hi-fi loudspeakers.
As for me, I connected it (like it's visible on photos I provided above) into my own hi-fi audio gear and....... if works _instantly_!!!!!!! Even I was kinda surprised. Hahaha.

Anybody who wants to compose music for ZX81 with TurboSound - and he has Windows on his PC - he can use THIS:
http://bulba.untergrund.net/VT1.0beta19.7z
When the entire 6 channels song is ready, the only thing to do is to save it as Andy suggested - and then change extension into *.TS.
Et voila.

Yes of course. The new GAL code (galasm). If needed I can prepare a JED file or send you a new GAL, just write a PN if needed:

On the MrX there is a port called K3 which offers each single channel from the ym2149.
21) ANALOG_CH_C Analog Channel C directly connected to YM2149
22) ANALOG_CH_B Analog Channel B directly connected to YM2149
23) ANALOG_CH_A Analog Channel A directly connected to YM2149
So in principle, taking the signals from there and mixing them in an !!!appropriate!!!!! circuit offers all kind of variations.
So theoretically 6 indipendent amplifiers with 6 speakers could be driven by 2 MrX boards or any other combination of those channels.
Of course on the ZXpand AY + MrX this could be possible too, however I think the connectors must be soldered directly to the ym2149 socket pins of the ZXpand AY? Sirmorris, please correct me if I am wrong.
Here is the description of the MrX and its ports.

Re: What's this then?
I realize that raw discussion cannot actually express what exactly we're talking about and I must admit I have some desire to record 1 or 2 more songs of various authors to let the people exactly know what is our subject-matter indeed.
We will see.

Re: What's this then?
Hello,
I added chapter "7 Six Channel Sound (Turbo-Sound/Turbo-AY)" for 6 channel sound on MrX card to the Manual.
For those who are interrested, you can download the manual here:

Re: What's this then?
A very good idea.
As for me, like it wouldn't be hard enough to make music on real ZX81 hardware , I decided to try to make a TurboSound song entirely on my ZX81. It will be kinda crazy dance over the computer, because I will not hear both halfs of the song at once but I will try after all.

Re: What's this then?
...and yessss - I finished it today.
And this is another song entirely made on ZX81 and ZX81 only.
http://zx81.republika.pl/one_zonx.zip
This archive is for 1 Zonx' owners.
It contains the STC file for STC-player's users
and
SNG file as another demonstration of the ZX81 SoundTracker.
This time the song contains also the 'buzzers' - AY's hardware envelopes - to show to interested people how to make and use them (with A/E and C/8 commands) on bass.
This is file for TurboSound users: http://zx81.republika.pl/two_zonxes.zip
that means owners of 2 Zonx interaces (probably 2 Mr-X modules or one Mr-X and one ZXpand-AY).
As I was making it entirely on ZX81, I wasn't able to constantly check out how both halfs of the song work together, so actually the second AY gives only some "deeper" sound this time, nothing more.
After all, I think it's a really decent sound, pretty powerful with 2 Zonxes.
(Although it's a little bit slower in TurboSound version).
PS: MP3 recorded from real hardware: http://yerzmyey.i-demo.pl/Yerzmyey-Earport.mp3
PS.2: Thx a lot for all the soft/hardware to: Sasha2000, SirMorris, Andy Rea and Moggy (for software-ports for more stupid users like me).

Re: What's this then?
Hmmm.
Who would think what's possible to do with ZX81.
http://zx81.republika.pl/ursula.TS
This is my the first song really for two ZonXes - one half cannot play without another.
Still, I used only a real ZX81 to make this (first - one half, then the second one) with Andy Rea's ZX81 SoundTracker.
Also I recorded it from the same ZX81 with ZXpand-AY and Mr-X modules (using TurboSound Player).
It's a rare phenomenon I'm content of my songs, but this time I really am.
By the way, the title is a joke again, because we (as many nations) have "Ursula" name - but diminutive from it we have: "Ula". And we treat the ULA chip as a girl's name (like PAULA in Amiga or whatever).
PS: For people who still consider gettin' the TurboSound setup but haven't it -
