Frank Trigg's Theme for Carlos Michelis (2012) on the ZX Spectrum (AY sound chip). This has been one of my favourite AY tunes since this song was released.

Why does this sound like it could be in star control 2?
I watched both videos, but I don't see or hear the difference. Protracker2 has the following for the 8xy command: x is set to 0 or 1, to use a 3bit or 4bit waveform respectively (also changes note by one octave). SAA1099 has envelope generator bit 4 (En4) defined as: 0 = 4 bits for envelope control (16 steps) 1 = 3 bits for envelope control (8 steps)
I think it doesn't sound much different unless you have some good speakers, and I did a little hunting about the envelope control. With 4-bit envelope control because there are now twice as many steps and the SAA internal counter is running at the same speed, this leads to a lower ocatave (the frequency is essentially halved), but if you're posh and have an oscilloscope you can see sometimes it only outputs 3bits (I don't have one). So if you look at register 2 here (th-cam.com/video/PeXuQQE-eRg/w-d-xo.htmlsi=akrFSO9WOnciZ2Dk&t=2), the triangular bit is playing at a different frequency to the other version (th-cam.com/video/WvZDLUfJY9g/w-d-xo.htmlsi=BmfczsKvF8HY_hDc&t=3). I checked through Andrew's compiler-player code and found it was treating it exactly as I expected, but don't have access to the Protracker in-editor player source, so I went with that version. However the fun really came when I found this sometimes appears to be randomly jumping down more octaves? Or not triggering at all? I'm not sure. And the effect was produced in the game, in my demo player, on SimCoupe and on the real hardware. Very strange indeed - any ideas?
You are right, the first part "Title" has a visible 3-bit envelope in channel 2, compared to the 4-bit one in the "bad" version. The second part "Manhunt (Intro)" has a 3-bit envelope in both versions. My YM-Player also has strange envelope behavior, but I haven't investigated it.
@@balorprice "but if you're posh and have an oscilloscope you can see sometimes it only outputs 3bits (I don't have one). " - what do you think these videos are?!?! 😀
@@StefanDrissen the view from the other side of the velvet rope!
This looks more like a VIC?
Really? <runs off looking for VIC oscilloscope videos />
@StefanDrissen ah yes html tags
How did you separate the channels? This is super cool
First I made sure I could compile Fuse 1.6.0, I then compiled it three times, each with volume set to 100 on only one channel in sound.c. Launched these three instances, with output to a fmf, which is then converted to a wav. The three wavs are then sent to sidwiz. Easy peasy 🙂
Would you like a neoGS?
Merry Christmas Stefan, thank you for all the bangers this year
@@ozzie_goat Merry Christmas!
Thanks for recording this. I had only a very low quality version in 96kb/s , that I recorded long years ago from an emulator... The music file is to big to pack it into AY file.
*boing*
Bet that eats up all the CPU time too
A lot, but not all, the visuals are still impressive - see the demozoo link
Creating this recording on the other hand, did eat up most of my CPU time ;-)
Go AY chip go!
I don't know why the algorithm led me here, but I like it!
eerie !
I love the whooOOP sliding notes in this one. I really like MmcM's Wonderful Dizzy tune as well; I'm away to listen to a few more of their tracks now!
At least 3 good cover versions exist for AY. 1 this one by The Lords 2 by Fuxoft 3 by Kangaroo, for CPC 4 CPC original from the game = not good, anonymous. I have the game with music by Fuxoft, title song looped. I have never heard The Lords music in ZX Commando game.
Thanks for sharing this!
Agreed
Stefan I just sold £200 worth of speccy interfaces!
visceral, gritty, 4 bit is enough.
special envelopes.
Seems like the correct tune for the Commando theme for the ZX Spectrum 128K! I'm aware there was an unofficial 128K version of Commando for the ZX Spectrum.
squares vibing
One of my favourites! Love this song, the harmonic progression is so well crafted
Blimey, that's a proper ending! Excellent stuff
This is excellent!
Wow!
Was ist das für eigentlich für eine Wellenform?
Is there a cover of Contra in there? A workmate reckons there is.
This is really cool to see Stefan! :) I made this music for the Space Adventure Simulator 2 but I thought it sounded right for the Arkanoid2 demo so I borrowed it!

Is it 8bit then?
Is it 8bit?
Is this 8bit?
Is this full 8bits then?
You said that 1mb ram means faster sample frequency yes? Is that full 8bit playback? Abyone work8ng on 16mhz80 for sam?
What was this music used in?
They were included on Fred, which was a disk magazine containing articles, demos, music, artwork and full games
how in the world do you sample on the sam coupe
Record or playback? For recording with original hardware you could use www.worldofsam.org/products/sound-sampler or www.worldofsam.org/products/quazar-surround-sampler-module . For sample playback using the SAA1099 read www.worldofsam.org/products/based-idea-issue-1
😁😁
Oh and can enterprise run speccy 128k software?
Can enterprise at 8mhz do this?
That's fine mint Stefan I told you so!
Help me stefan im drowning!
