MECΗ HΛVEΠ: Behind the sense 0002 - OP Blocks [FMX update]

Post by Logickin λ »

While seeing people making 4 operators FM and posting different algorithms separately while back.
I was thinking: Is it possible to make a FM module which has an ability to let user to define their own algorithms, to make some complex sound design or provide an easy way to explore FM synthesis?

Yes, there are a few ways! However, I found that using the modulator do have a problem, which the modulation result of a lower octave sounds too gentle, while too harsh on the higher octaves. On the other hand, using Generators with FM input will giving the total opposite result, harsh on low end, but too soft for the high end, making some sound design not consistent.

And here it is, introducing the OP(Operator) Blocks, which was used for the bass of the Compo Entry! OP Block doesn't sound OP on its own unless you chain them. It has a major features, which regulates the loudness of the modulation signal by pitch, making the modulation level of different octave being more even. (Loud volume alert)

Thanks to the delay now have an ability to passing midi note, you can now define your own FM algorithm by linking multiple of them, to making some classic FM sounds (Ah yes, a horrible version of the game ranger x/ Ex ranza theme). Not only to the op blocks itself, but you can also be creative by linking some LFO to do some wobble bass where the op block can reset the phase of the LFO, or you can change the waveform to do a very consistent Sync Effect, or you can even put some 2nd order karplus-strong to modulate the signal of the OP Blocks.

Then here is the module:

There are some limitations for this module [Updated]:
1. It is confirmed that the modulator inside the OP Block might produce unpleasant noise by chaining multiple of them. There are 2 work arounds to solve the issue:
- Set the "Source - Operator Mode Ratio" to 0 to Skip the main modulator when an OP Block is in source mode
- Use the "Key Tracking Filter" I have created earlier (https://warmplace.ru/forum/viewtopic.php?f=11&t=5721)

2. Missing "Draw Spline" which is used for the song Mech Haven
- OP Block Interface, the FMX based version, have such waveform recorded inside the custom waveform.

3. The module is monophonic
- You have to use multiple instance of it. You may define an algorithm first the use the "Make MetaModule" options, and copy that MetaModule.

amazing! this is a truly modular approach to fm that modules like mine fail to implement

i modified your synth a little by changing the generator to an analog generator - i think this works better, and it allows for more waveforms

There was a reason to not use the analog generator, since analog generator has a relative low cutoff frequency for the anti-alising filter which start attenuating in volume on higher pitch from around A6. The attenuation is not a bad thing initially, but it makes the modulation result less consistent. As a result, standard generator is used.

Perhaps I will update this module in the future with a bit optimization before release to the SunVox Synth Post.
I will include A type(Analogue generator) and D type(Standard generator) as well, so you can choose either using the extra filter noise from analog generator or using that unique duty cycle sine wave from the original generator.

Amazing Job, I will experiment with this block soooo much!

There is a big update for OP Blocks!
- Reworked architecture, with less unnecessary parts.
- Source mode and operator is replaced by a parameter, Source - Operator Mode Ratio.
(0 = source mode -> something in between -> 32768 = Operator Mode)
- Bypass modulation intensity regulator
- Now OP Block type A is back!

Now this module has its own page! Get the latest, FMX based version! I have been using this version for awhile, it is more stable and much smaller in size!

it just occurred to me: this is awesome, but it'd be even better if you could add some implementation of this: https://warmplace.ru/forum/viewtopic.php?p=22452#p22452

it would make sense since operators are being handled low-level with this module, so a way to easily add custom waveforms would be relevant to add

Sure! Considering I also want to make some updates to the module for extra functionalities.

Thanks for your example about loading custom waveform! This not only help me to improve the OP-block, but it also solves one of the problems for my upcoming project which requires a perfect FMX sample!
