The 50 pages manual is done and the website is almost ready to receive the baby.
Don't forget you got TIMER effects + a built-in AY3 8910 envelope generator emulation and some unique NOISE tweaks inside!

The manual itself is a good resource for any PSG fan smile grab it!
MANUAL DIRECT LINK >> http://www.alyjameslab.com/tutorials/SP … MANUAL.pdf
FAMILIARIZE! smile
you can start to lurk around at www.alyjameslab.com
I also plan to do a series of video tutorials next
the Paypal button will work DEC 17
So far it works great and should run on any DAW, It have been tested in CUBASE,ABLETON,FLSTUDIO,RENOISE and Standalone VST Host

Currently writing the manual...release in few days!

It is a 4pole Lowpass filter with adjustable Q (resonance) and cutoff frequency smile can self oscillate at high Q setting. it is DSP based.
So basically a Moog Ladder filter clone digitally.
So you don't really need an analog MF 101 it your budget is short.
Any software based LP resonant filter can do the job.

The whole mixer unit in this video cost the same as 1 MF 101 smile

IIRC it use multiple MIDI channels? Haven't mess around with since but it should be something like MIDI#1 >> PRESET#1 ...maybe.

Have a look here http://chipmusic.org/forums/topic/2196/ … revisions/
might help ;p

"will be trans-coded into a VGM File (soon)." yeah! waiting for it :3

I am waiting on Valley Bell's side (VGM format authority) to update the current MIDI 2 VGM converter to support standardized MIDI CC# (GenMDM, FMDrive...)
I gave him an updated list and also informations how to handle CSM...
He will take care of this in his spare time.

For now you can still convert to VGM with mid2vgm if needed but you cannot change one parameter without sending a patch change.
That is why MIDI CC# support will be handy.
If you can go for now with "static" presets and Program changes it is already working! smile
EDIT: You can still make complicated evolving sound on only one channel with patch changes...it is just more programming work.

Yeah the ladder effect can be good for distorted sounds, for example starting a line at low volume will start distorted then slowly becomes cleaner as the volume increase. This type of effect is impossible to make with a clean sounding model.
On the other hand I agree that a clean FM sound is preferable for most of the things smile
That is why I got both and even an YM2151 with external DAC when in need.
On top of that there is even a mod for MD1 that consist of replacing the YM2612 by a YM3438 chip (the one that is included in the custom asic of MD2) however there is a need to keep the YM2612 only for the Timer to not break compatibility...

I have added both models in my FMDrive 2612 VSTi for the same reason smile

So basically Super PSG Vst is ready ! smile
I will need a few more days to make the manual (lot's of features in here) update the website and make the release news public.

There is a common mistake about the MD sound...
To simplify what is considered "best natural sound" is early model 1 that contains "the ladder effect" you talked about and the output circuitry gives a nice bass response.
then there is some later MD1 and some MD2 that are considered "bad sounding" they do not have the ladder effect anymore but the output circuitry is crap...
Also there is some MD2 with a modified DIY output (CCM crystal clear mod for example) that gives the cleanest sound.

Anyway, I personally prefer the distortion (ladder effect) that gives the MD output a special character smile

Either way, it'll be relatively easy to construct some hardware to do that outside the chip. Thanks, though.

Doing that is Useless in your case, you will end up inverting the whole chip output smile

If you still want to do that, depending on what hardware you are on, if it is a Sega Genesis you can use the PSG to output an inverted Saw wave and it will phase with the Feedback operator...

AKAIK you can do an inverse saw (ramp) in some way, by using the SSG envelope (4) Inverted loop, when the envelope goes short you end up with a ramp, assuming AR is 31... the problem is that it will make another tune than your main note and the volume will also be quieter (especially on real hardware)... it is up to you to try to find a setting that can make an acceptable phasing smile I doubt that you ends with something useful but you can have one note with for example:
ALGO 7  OP1 Feedback 7 and lower volume and OP4 with SSG (4) inverted loop.
You will hear what you search for when you reach the point that the key you play is almost in tune with the period of the SSG loop..

BUUUT... you can do exactly the same phasing thing with the PSG and this will be far more easy an controllable smile

I just complete an FB01 FM (YM2164) Module whole banks patch rip for FMDrive! (.tfi format) available for free download in few days @ www.alyjameslab.com (download section)
This patches are YM2151 compatible but also YM2612, they are pretty classic but really nice with velocity sensitive input.

I will also link you all to a PCM samples dump archive for a bunch of Megadrive games
and finally put in the download section my modified version of oerg866 VGM PCM data Dumper (sound added when searching/extracting and basically skip the registers extraction part) to dump your own samples from VGM files smile

Aaaaaaand ....the PSG vst is Done! I will need a few more days to update the website and write the manual (because there is a looooooooooots of features) then I will drop the release Public on the same basis as FMDrive smile smile smile

Someone actually made FMDrive works on Linux via Wine smile if someone wants to try, send me a PM, I will get you in touch with the user.

I can agree with that. I love that radnessss. that transient trick is a good one. I have used it in other things  when synthesizing sounds on my laptop but never thought to try it on chip hardware.

One thing that i noticed in the FM world that i miss about the subtractive synthesis is that there is a strong emphasis on trying to recreate real life instruments. Personally I favor letting the FM be its own sound. For me the sound replication always ends up sounding boring and generally cheesey. It wasn't until i heard those "BRAAAAAAAAAG" and "TWAAAAANG" soundeffects that i got into FM synthesis. Ultimately thats why I ended up liking the mod version of this better.

The genesis/megadrive was such a powerful machine sound wise. It has so much potential. It has soooo many modern applications in music production. I mean the polyphony trick is totally proof of that. It really does stand out as its own instrument.

I agree with that smile FM really got its own sound especially when you do some real time modulation, the YM2612 also got the SSG envelopes witch are looping ones (the looping can reach audio rate!)
One example demo here(only FM + PSG) with a modulated lead (3 channels) https://soundcloud.com/alyjameslab/ym26 … ve-vst-psg
And some FM +SSG envelope + CSM >> https://soundcloud.com/alyjameslab/glitches-brew

So... I'm getting some crazy amounts of aliasing. Is this how the Megadrive actually sounds or do I have a whack console? I got my hands on a japanese model since I read on some forums that they had the best sound output.

It's like... I have a hard time hearing there's an actual sine tone underneath the aliasing.

Might just be that I just need to figure this out.

Here is what you should get if you got an early model 1... >> http://www.alyjameslab.com/tutorials/MD1_LADDER.wav
what you call "aliasing" is a known "bug" in the early YM2612 DAC. It is better known as the "Ladder effect" in the MD scene.
Or maybe you actually got real aliasing but it is not going to happen on the sine signal alone (just one operator with no modulation).

I know well this effect as I have emulated it in my FMDrive 2612 Vst ... please post a recording of your crazy amount of aliasing and your console model.
