On the SY77 every operator has two inputs. When not used by the algorithm a free input can be used for a user defined 2nd feedback path or even patch in a AWM part. Unfortunately they dropped these options in later FM versions, the 2nd feedback path is quite a usable feature. In a way the synth engine of the SY77/99 was more advanced than that of the Montage and MODX.

I think Jon Schatz in a recent update for the ID700 gives the option of more graphically discernible configurations for anyone interested. I really love that app and I'm not really into, but greatly appreciate, vsts. For what it's worth a Buchla700 reimagining would be my ultimate fantasy instrument. When I use the id700 it does help inspire my patching on my small 200e; I wish one could change out the wavetables on the 259e.

I've wondered what a modern Buchla 700, call it a 700e, would look like. People might say, well, just get a computer with a DAW you like and run ID700. But you also need a touch surface. And the 700 also has those CV ins and outs. Well, you could add a MIDI-CV thing. But then an appealing thing of the 700 is its compact size.

2:00 Moselle has had "waveshaping" penciled in for a decade. If anyone has some favorite waveshapers I should take a look at before making something dedicated, please let me know! That said, the normal math operators SelectN(), SelectLoopN(), Select(), LinFade(), LinFadeX() and Peak() do most of what the Map() module was meant to do. You can also do all sorts of waveshaping with logic and math functions. For instance IF( Signal >.5, .5, Signal) would clip the input signal. Tanh() can give classic tube-style nonlinearity as the output keeps getting higher but never quite gets to 1 no matter how high the input goes. You could run a Sawtooth LFO's Positive output into Sin() to get a "poor man's sin oscillator" and do all that kind of thing.

I was so excited with this that I made an approximation of Config #02 on the Gotharman's Urano modular-in-a-box with either wavefolding at the end, or having oscs 1 and 3 be wavetable oscs with VCAs 3 and 6 modulating the tables. I gets quite weird (and fun). There is a massive amount of sounds to be found in just this one configuration/algorithm. Need to try out some of the other Configs.

Can you run moselle at higher sample rates / use oversampling? I ask because the digitone made me realize how much better fm sounds when the modulation is done at ultrasonic rates - the digitone uses 192khz if I'm not mistaken, and it results in much smoother and glassier tones and less of the "Sega fuzz" we traditionally associate
@superultramegarobot
3 ай бұрын
(continued, accidentally pressed reply too soon) ...we traditionally associate with the FM sound. BTW, digitone also has a somewhat similar feedback algorithm if I recall correctly, you can check the manual to verify but there's definitely some feedback configurations at any rate.
@Lantertronics
3 ай бұрын
Yeah, FM can get nasty at high indices of modulation if there's a lot of aliasing. There's a place in the configuration file of Moselle where you set the sample rate. This needs to match the rate of your audio interface -- to my knowledge it doesn't do upsampling, but if you run it and your interface a higher rate, you could always take the rendered file and downsample it later (I personally don't see a need for higher rendered rates than 48K, since all modern DACs are fancy upsampling ones anyway).
@superultramegarobot
3 ай бұрын
@@Lantertronics Dang, they should still add a specialized oversampler similar to some supercollider ugens. Oversampling the entire DAC is a bit overkill - it's mainly the modulation that needs to be oversampled, since FM generates a lot of higher harmonics and chaotic behavior once feedback is introduced. I'd recommend checking out the sound of the digitone, I've yet to find another FM synth (plugin or hardware) that sounds as smooth and glassy, and it's all due to the oversampled modulation IMO.

2:15 Without any disrespect to the Buchla engineers or the documentation effort, showing the crossed lines on config #02 and #10 wasn't strictly necessary. It would be understandable if they wanted to maintain all operators with inputs on top, outputs on bottom, as in the renowned diagrams for the DX7. The root problem, I think, is that they only had maybe 80x60 pixels or so to work with.

3:29 Yes: FMAlgo can be totally replaced with Osc blocks set to sine waves. In fact you can also write the same thing using raw math with the Sin() function and Note:Time and Global:FreqEval (the sampling rate). But FMAlgo will be a bit higher performance and as you say, hopefully easier. BTW there's a Word manual that is 80% incomplete but has a nice chart of how to do the Yamaha DX7 algos in Moselle.

The main thing I recommend is dropping the 1/k scaling with harmonic number k on the harmonic coefficients. Constant coefficients should give me impulse waveforms, 1, 1/2, 1/3 should give me a sawtooth. I realize that involves changing a massive amount of the tutorials, but as it is it's going to lead to tremendous amounts of confusion -- I'm not aware of any other synth or software or textbook that uses an hidden 1/k convention..

NI FM8, Steinberg HALion 7, Image-Line Sytrus, these all have freeform FM matrices where you can route any operator into any operator, so in theory you could have a 6-operator deep feedback chain (with each of those operators feeding back to any other operator in the chain simultaneously, AND itself), in case of HALion 7 you get the FM-X engine, which is 8 operators, too...
