Version1 kb. Very light! Signal Flow:. Presets: 47 included with the patch.
Here are a few more - one for each of the different algorithms documented on the Routing page. Samples: Here. This is designed for slightly easier patch editing, and includes a number of new presets. Although the signal flow diagram does not reflect the changes made to the new version, all the text below remains relevant, and the signal flow diagram will still help in understanding the composition of an FM synth. The original YM was a chip designed by Yamaha which was used in a great number of devices from the late 80's onwards.
The YM is an emulation of the chips implementation of Frequency Modulation. Frequency Modulation is the method of synthesis in which the frequency of the sound is changed by the frequency of another sound with a frequency within the audible spectrum. Imagine a patch in which you are slowly modulating the frequency of a Sine wave using a slow Sine LFO. The LFO's frequency is significantly slower than that of the audible signal and we hear a familiar vibrato effect.
Now imagine turning the frequency of the LFO up until it actually exceeds the speed of the audible sine wave. What happens at this point is that the modulation effect on the audible wave becomes a distortion within the individual cycles of the wave, and as a result, a great number of additional frequencies are generated and this can dramatically alter the character of the signal.
Due to these extra frequencies sidebands generated, FM is capable of creating tones quite unlike conventional methods of synthesis. It is particularly well suited for the creation of metallic, bell-like tones, but has a great many other uses besides, as the 47 presets which come with the patch demonstrate.
Further modulation possibilities open up when it is realised that an Oscillator can be fed back to its own modulation input and modulate itself, and also that groups of more than two Oscillators can be used to create very interesting timbres. The Yamaha DX7 used 6 operators, which allowed for 32 different modulation routing configurations, or algorithms, as they are known.
See the routing page for more on the algorithms available in this patch. Frequency Modulation as a type of synthesis was pioneered in the 60's and rose to prominence in the 80's as Yamaha developed a number of synths relying heavily on FM as its foundation. You can read more about these in the Pulsar and Poison manuals, get them here both of which have an introduction to FM synthesis concepts.
For this patch, Arikama has taken the specification of the original YM chip from Yamaha and recreated it in Modular form, with a few enhancements.
For example, the original only had one Operator capable of self modulation, whereas the YM has two.Wonka quiz
He got the information about the chip from this book:. If any of you know of an English book or website which has similar information about the YM please let me know and I'll post details here. More details about the patches construction, the algorithms, etc, can be found on the routing page.
For further reading on the subject of FM, I can recommend the following articles:. The later part of the article is more specific to the Nord Modular, but still interesting reading. If you don't 'get' the maths, you can still understand the principles of FM perfectly well.
These articles are currently subscriber only - I'll link to them here when they are available for non-subscribers. Malfunction's FM Synthesis heaven is a good starting point for trackers, links, etc, while ChipTune is my personal favourite.

The YM chip was tested and working, and is a part of the official CX16 emulator. When will progress begin on implementing the SAA chip? GregZone Member.

Another summer closed in your room playing gamesBy alex. Alex, not satisfied with the current crop of audio chips available for the Papilio, is embarking on a mission to get a FM Synthesis chip connected to the Papilio. His target of choice is the YM audio chip that was used in famous games like Double Dragon.
His plan is to physically connect a YM chip he bought off ebay to the Papilio. One of the hurdles associated with the chip is that it does not have an onboard DAC, but rather then be a detriment he is using that to his advantage by feeding the digital audio data back into the Papilio so he can add new effects and then use a Delta Sigma Dac.
As great as the famous C64 SID chip is, it is not the only way to produce great music and sound effects. There is another category of sound chips based on frequency modulation FM synthesis. These acronyms indicate how many oscillators per channel the chip contains but they all fall in the wider family of FM synthesis chips. The YM and others in its category do not output analog sound, instead they output digital data over a serial channel. To be honest, the idea for this mini project came to me after browsing though various schematics of arcade games.
I came across a high res scan of a schema for the arcade version of Double Dragon. This was one of those rare schemas that are clean and legible but also just real easy to follow despite it being over 20 pagesit's just a pleasure to look at and it just makes sense. The signals that cross pages are also very easy to follow because the designer labeled them not just with the page they connect to but the coordinates on that page as well.
This is one of these games that have a separate sound board, complete with its own CPU. The interface from the game board to the sound board is via a simple 8 bit port with a single strobe write signal.
I had the feeling I could just implement most of this sound board on a FPGA and then simply drive the external YM chip with the signals produced by this sound board implementation.
Wiring all the external chips on a prototyping board is not really that hard, below is the basic schema that needs to be followed. So in order to implement the sound board on a FPGA I need to figure out how the main game communicates with the sound board. Focusing on the main game CPU is the wrong approach here though, this is like taking the long way to get somewhere, the right thing to do is look at the sound board CPU and see how it needs to be "tickled".
Here is the schema with irrelevant bits taken out. This clocks in the value from the DB data bus into the IC17 latch. Simple stuff so far. The reason we ignore some of the code in the middle is because I've already analysed it for you and I can tell you it's not relevant for our discussion.
Well if we lay out the address lines as A15, A14, Looking at the schema we see these lines are connected to address decoder IC79 pin 5 on that IC is not labeled in this cut down schema but tracing it on the real schematic shows it going to A15 on the CPU.
IC79 is a 3-to-8 decoder meaning the 3 bit binary signal presented to its inputs 1, 2 and 3 is decoded so the corresponding output 0 through 7 goes low.
Pins 5 and 6 are active low chip enables meaning they must be low for the chip to do its job. This output goes to our familiar flip-flop active low clear input. Using this trick I can see that the following values cause the following things to happen. There are in fact two identical circuit duplicated so two effects can be played simultaneously. I won't show an analysis of the circuitry for the effects but roughly it works like this.Get It Now! Get FMDrive! You can import and export.
