I don't think MaxYMiser tunes would work on anything but Atari. Especially not STe ones. YM and AY are not exactly the same.
Thanks 
then atari is not allowed
Coooool -- I guess that if you're looking to publish a music disk, that snd/sndh files generated from MaxYMiser on Atari STe aren't allowed?
If that's the case, I guess I'd better dive into Vortex..
i think there is no diferences between YM and the AY, so is the chip is the same? In that case it will suit the compo and the CD
the musicdisck depend on the coders, at the moment only coders for the MSX had confirmer they can manage pt3, wyz, or trilotracker
Culturachip is a spanish speaking active chiptune community, we hold about 5 compo/releases each year, this time in collaboration with AAMSX we are starting a new one and we are opening to international participation.
The excuse , this time, is the 30th anniversary of the Amstrad computer, and rules are:
Music composed for a single AY chip, no restriction on what tools or computer are used as long as the result can be played on the real thing (Vortex Tracker, Soundtracker, Protracker, Arkos, Starkos,..amstrad, speccy, apple ][, PC,.. ) (AY emulation is of course allowed).
Multiple submit allowed
No previously released songs
No versions or covers
Deadline: 12 November 2014
Send entries to: rolemusic somesymbol gmail period com
After deadline all contestant must vote, songs will remain anonymous till the end of voting
Results: Will be presented at RU meeting (Barcelona), available on December 2014
Somehow Vortex Tracker II is recommended for newcomers to AY (works on windows/wine, easy to track, compatible to all platforms....)
After the compo:
A DIY CD-Audio with printable cover and loseless .iso will be done. People who want to enter on the CD must accept a CC-BY-NC-SA license, and give selling rights (at a friendly price) to the rest of the contestants. We do this to help refund the cost of printing, burning, or help some cost of future selling it in stands aimed to promotion and put the thing out there. (notice that one can enter the compo but choose not to be on the CD),(also notice in case the total playtime exceed 72 minutes some tracks may be edited or discarted)
Musicdisck on a msx computer, and maybe on amstrad and spectrum too. (we recomend using .pt3 format due its portability)
PD:
The result will be kinda as cool as like that this last one we did to celebrate 30th anniversary of Nintendo NES

alone coder 
thanks for the listen and the replies mates ^_^
As you ask about our own thougths, here's mine: I like CGB internal prosound, in fact is my favourite, I never use headphones and I am used to low signal levels, but anway I wont call that one a low signal in case you compare it to other signals, such as the ones of a electric guitar or a Amstrad computer, other thing I like is that the signal keeps between certain boundaries, that allow you to record easily, you can almost adjust the volumen to get a nice signal withouth need to use a limiter
not really a solution to your question but that screenshot seems like an old version, I think 3.72 is the last
and this page has a good downloable database of speccy programs and btw a prety cute screenshots to look at
yep ,rite I've just checked this, I'm using openMPT and had checked by default the option of "volume columm are note velocities"
so anyway using VOLM and some kind cc7 mapping may do the thing perfectly
I have sucesfully send and record midi sending velocities using a VOLM00xx effect in every note, with xx from 00 to FF
not sure if that really sends the velocity or the midi volumen, maybe is not the standard but my daw get it as the velocity, maybe mGB dont do so
well the EQ thing in the comparison is between those two models, but I believe (hadnt tried though) they really eat the bass at a level you cant fix when compared with the DMG, if a frecuency its eaten mean is not there even you EQ hard
I had been always tickled by the fact that sometimes seems to be a "need to" buy a DMG to make chiptune with portable nintendo devices, the only reason given is "it has more bass"
so I made a comparison merely for fun some weeks ago trying to be objetive to find out what's happening with those machines
On the pictures on the top is always the Pocket Game Boy as is, and in the bottom the prosounded Game Boy Color (the ones i have btw)(i have no clue on how prosound affects PGB but boths seems the same machine)
Sawtooth bass on WAV
Both eat the bass harmonics really hard, seems color has a little more width but nothing you can't do with EQ. On a spectrum analysis PGB has more frecuencies around <40hz, might be noise because its under the fundamental
When you draw in the wav channel the output signal is inversed, so i actually drew a ramp /|/| up and the result is a sawthooth |\|\, the ground is on the top of the lsdj wave drawing tool, that doesnt affect the sound as our brain only understand harmonics
Triwave and Sine on WAV
Say Goodbye to bass frecuencies, seems again color has a little more bass frequencies but none to care, on the fun side triangular seems like a pulse and sine as a triangular
Pulse
I cant spot difference
Noise
Not the same at all, or may be my the randomness that make my soundcard capture differents samples, anyway both sound the same to me, is clearly obvious that both are precalculated and follow the same algorithms
Mix of PU1-PU2-WAV
Not the same, but I can't tell by ear what's better (despite the pocket hiss noise)
Mix of four channels
Not the same, but I can't tell by ear what's better (despite the pocket hiss noise)
Musical Context
http://culturachip.org/compos/test/imag … pocket.wav
http://culturachip.org/compos/test/imag … -color.wav
A small saturation on the mix, but that is what happen always when your waveforms are pulses. Is possible to reach a clean melodic bass to make the sound clearer. Both are really great machines to classic chiptune sound, with a sharp and precise a tone. ( as i mentioned I'm not sure how the prosound affects the pocket, in the audio example the pocket is obviously noiser).
For a dance with kicks or a d&b, I dint like the ones I've tried
Spectrum
At mentioned on waveforms seems that color had more bass fundamental frecuencies, although not a difference you cant solve (or not solve) with EQ, the spectra is really the same. Color->Blue, Pocket->red
Machine Noise
Pocket has a high fiiii and some fluctuation on the bass frecuencies, the fiiiiii really makes the sound worse if you want to sharpen your ear as a hi-fi listener, on CGB all the noise was also present but totally removed with prosound. Note in this graphs the amplitude scale is zoomed hard.
Conclusions , (1) Both are the same thing?,(2) Excellent ratio signal/noise on GBC , (3) No enough bass harmonics (4) Prosound really works
Personal opinion: For a classic chiptune genre they are really nice. For making great leads are also good machines. To make dance music I wont bet for them. The sounds is very sharp and with a really warm digital tone. I think they are a bit bullied and underrated because its inefficacy to reach basses.
Best bass I've found for the kind of music I do is drawing a mountain like a narrow gauss bell, that gives a tone that doesn't dirty the mix on the pulse range and has a good presence at bass frecuencies. It does look somehow similar to what a electric bass produces near the attack zone.(again is inverted ground in the lsdj draw tool)

Ok, Ok, thats was for fun, although is trying to objective is obviously not a serious analysis because no prosounded pocket, no dmg, no enough measurements on the scientific standards..... but as I did on a bored Sunday weeks ago I thought that might be fun to share here
up the GBColors!!!, and remember electric guitar has no bass and remains the most overrated instrument in the last century
So its fantasy time , as I use piggy only on PC mostly because I like its minimal interface and I would like the keep it minimal .i.e. sample/sf2 based, rather than new features I hope some day behaves as other sample based trackers:
optional channel/instrument volume ramping
playing with soundfont or "sine alike" samples produce this high offset cliks, Ive tried to minimize them playing with volumes on tables but either is not functional and some times is embarrasing or imposible to get rid of them withouth loosing the whole atack of the sample
