I was thinking about this a while ago, but never knew just how many synths ran on the 56k (tons of FX used it too). I'd say it's about time for a soft virus. Kind of surprised it currently maxes out an i7, probably still plenty to optimize.

Just on that retro FM thing, I'm probably looking at something simpler like a Reface or a retro vst to do older FM synth noises because my MODX kind of cheats me on trying those things, its FM side and AWE64 side seem to be really the same thing on the hardware level. The FM algorithms are simply not geared for the same ideas, it's intended that you use a couple of them in tandem with the AWE64 engine if you want simple sounds, and the bulk of the algorithms are for much more complex layered ideas involving Yamahas arpeggios, The AWE64 engine is really a collection of filters on waveforms plus many goodies on top to make them do fun things. This is all great for flexibility in one sense but it is the Yamaha Way or the Highway in all others! Quite ironic then that so many patches refer to past equipment and of course I have DX7 and CS80 patches in there too. But I'm underselling the complexity of it, there's so many interconnections that I'm still lost a bit with it. I haven't got to grips with the arpeggio engine yet because I keep doodling with the patches :v:

I'm trying to remember the name of a piece of gear and I'm wondering if this thread can help. I actually owned one about ten years ago. It was a sort of hybrid acoustic/electronic hand percussion deal that had a head more or less like a tabla and an internal pickup, and then (IIRC) applied a whole bunch of processing to turn that signal into a whole bunch of weird noises. Any idea what I'm talking about?

e: And ten seconds later, I find it. It's the wavedrum.

Reverse engineering starts with knowing what everything does in the first place.

For subtractive synthesis, the waves go through a filter. Get yourself Vital. Vital has a great UI and is very graphical about what it does. It even does a bit of FM, too.

Check https://www.reddit.com/r/synthrecipes/comments/k4n1jj/dx7_in_vital_sure_why_not_plus_a_crash_course_in/

Plogue Chipsynth MD, an audio interface, and a controller.

FM on hardware synths tends to be painful on low budgets.

I appreciate the tip, but I've been tinkering with Vital a bit and I somehow set the keyboard at the bottom to the lowest possible octave and there's no indication of the default octave anywhere and there's also no user manual so now I'm kind of annoyed that I have to keep remaking this setting over and over again. EDIT: Got it. Z and X change your octave. This isn't noted anywhere.

Everyone else, I read your posts! I'll start with subtractive synthesis for now, and worry about FM later once I know how synth itself works.

I’m the kind of person who learns best visually and through structured lessons so I grabbed Syntorial when it was on 50% discount a year or so ago. Haven’t regretted it. Really helped me understand subtractive to the point where I’m not just randomly twisting knobs to see what happens. Well, not all the time, anyway.

Though it’s pretty spendy and honestly probably everything there I could have learned via youtube for free if I took the time to research options.

That's been my biggest concern as I'm learning some subtractive synth basics. You have infinite freedom, which also means infinite confusion and analysis paralysis. Yeah, I can connect a sawtooth LFO to the pitch and pan of a 25% square wave and add a funky lookin envelope, but...what am I even looking for? I'm kinda aimless. I suppose that's where I have to learn music production and instrumentation, and that's a topic for an entirely different thread (I think).

I got something that sounds like Zelda II, at least. :v:

All right. It's Saturday night; I have no date, a two-liter bottle of Shasta and my all-Rush mix-tape... Let's rock.

Start by trying to synthesize real instruments. Try to make an oboe patch and a harp patch. Stuff like that. With the filter open, pick out an amp envelope that mimics the instrument. A harp has a fast attack that rings out, a woodwind has a fast attack with a little decay and as much sustain as you have breath. From there choose a waveform. String instruments tend to be more sawtoothy and wind instruments and brass are more square.

After that you can develop your sound further. Can you add transients to mimic a finger pluck or initial breath? What about a delayed vibrato? And from there I would start looking at filter key tracking for brightness/darkness, adding more oscillators for noise or disharmony or droning, and lastly the effects chain

Not to discount any of the excellent replies above, but because I don't know any better, I've been having a blast with a volca FM I picked up used. https://youtu.be/lFfdOq9rvLc
It simplifies the controls to an AD control for the carrier and one for the modulator. It still has 6 operators, and a pile of algorithms, but a single knob can change multiple envelope parameters at once. There's a single lfo as well.
3or4 note polyphony. Can't remember ATM. And you can reportedly load dx7 sysex files right into the thing, and use dexed as a librarian for any patches you find/create. A midi keyboard is a near must though.

And if you're more like me, and not at all a musician, but someone more curious about making sounds and experimenting, check out vcv rack. Lots of free modules, and the ever present question of "what happens if I modulate this at audio rates?"

Ooh, that's kinda neat, actually! Too early for me to pick up, but I'll stay on the lookout for cool little things like that.

Good advice - I know FM’s pretty oriented towards trying to replicate existing instruments, but I never figured you could do the same with subtractive synth instead. I’ll approach it with replicating particular instruments and sounds I like in mind.

I'm trying to do oboe right now, working off of this clip of an oboe. I'm a little stuck on what waveforms make up this particular sound. I definitely hear a quiet square wave in the background (my poor ears), but neither another square wave nor a saw wave worked well.

I noticed that in Audacity, the oboe clip looks like this if you zoom in:



and I figured, is it not possible to simply work backwards from that target waveform and consider what waveforms would need to be combined to get there? I tried that out, and noticed that the target waveform looked kind of triangular. So I added a triangle wave, and:

https://voca.ro/16qJUGro0Yq6

That's not so far off, now is it? But the waveform isn't quite the same:





and I don't know how to get it closer.

Delayed vibrato I managed to implement (sine LFO @ 1/16 on the level for both waves), but I'm not sure what key tracking or brightness/darkness is.

All right. It's Saturday night; I have no date, a two-liter bottle of Shasta and my all-Rush mix-tape... Let's rock.

what software are you using?

I think the second waveform is on the right track but I'm hearing a lot more disharmony / offset in the real clip. so I would detune one of the oscillators a bit more. then I would listen to some solo clips of an oboe instead of just a short sample and try to get the legato settings right for keyboard performance.

key tracking is when the filter cutoff is set to be relative to keyboard position. so the more deviation from middle C or whatever the more it's open or closed. I would also consider adding some frequency tracking to the velocity for performance purposes

an open low pass filter with lots of high frequency harmonics can be described as "bright"

Interesting, okay. So it changes where the filter starts applying the (for example) low pass depending on how far you are from a base note. And as you go higher, the (e.g.) high frequencies get quieter/more muted. What is this used for?

quote:

Okay, so if it has a low-pass filter but doesn't cut out a lot of the high frequency harmonics, it's bright. I assume that the opposite makes it dark.

Pollyanna posted:

In a lot of modern synths, you stack oscillator voices on top of each other, with a tiny (adjustable) amount of pitch offset to create (usually) gentle disharmony between them, so as to thicken up a sound. I believe this is called "unison" in Vital, which lets you control how many oscillators ("voices") you stack. There's a knob underneath which lets you adjust the pitch offset.

Many acoustic instruments have different timbres at different points in their range; pitch shifting a low trumpet note up will not have the same frequency spectrum as a trumpet playing a higher note.

Been playing this, and at least initially it's more about logic puzzles than it is about synthesis itself. I'd describe it as more of a logic puzzler inspired by modular synths.

Ohhh, I see. Okay, so you can play two sine waves at once with one of them at a slightly different pitch than the other. And that "thickens up" a sound? When do you use that?

I would say you open the filter at higher frequencies more often than close it wrt key tracking. But that would be cool for an fm voice or something else that gets too wild in upper frequencies. It will have a calming effect basically

The biggest downside of Synth Secrets is no audio demos so you have no idea if you did it right or not.

Also, Vital can load and analyze .wav files, but summing basic waveforms is a bit of an uphill battle. For more consistent results, set phase randomization to off.

As for what to synthesize - lots of people start with an existing sound in a song they like. In that sense it’s programming - you clone Tetris because coming up with your own games is hard.

As for Zelda II - those are basic unfiltered waveforms :)

Yeah that’s why I mentioned the legato options, you have a monophonic instrument so its not so much about allocating voices into a unison mode as it is just grabbing another oscillator on your main voice. I haven’t used vital so I can’t say one way or another. I learned subtractive synthesis with es2 on logic, it puts a lot of emphasis on flexible patch points
