A bandpassed pulse form with some resonance and waveshaping to give the attack more body.

A simple waveshaped triangle patch inspired by, although not quite resembling, the interstitial music of the early episodes of "The Computer Chronicles." In the 80's, arpeggiation of these kinds of basic synth sounds was a typical "scientific" or "high tech" music bed.

This is the last patch I'm doing for this streak! It turned out to be very productive.

Low-passed sawtooth, with a sine wave to keep a mid-range in the mix.

I didn't include a delay in the ADSR controls, so it's harder to do vector-synth style pads, but not totally impossible. Here I sweep through three different oscillators.

It's a detuned sawtooth patch, but it's also a pulse width modulation patch. At first I thought I would have to add an inverted sawtooth oscillator or negative gain to pull off this classic trick, but then I realized that I could do the inversion with the waveshaper. I felt very clever when I did that, and then I added some modulation to the waveshape at attack time so that you get a blast of sawtooth followed by the PWM timbre.

Yes, it's another detuned sawtooth patch. This one went for a mix of filtered and not.

I improved the patch editor so that I could hold the shift key for fine tune adjustments. This helped me set the pitch LFO on this patch to 12.001 semitones(it still wasn't quite fine enough I guess). It's a sine wave but I waveshape the attack so that it's more squarish-beeper like and then filters out to make a cleaner echo.

Another tonal noise pad, layered with a square. Very "horror ambience."

I was feeling low about this synth yesterday, but today I come back with this sound which invokes a bit of that "Atari 8-bit" feel by using the tonal noise oscillator where it really shines - gritty bass sounds. I layer it with a sawtooth to distinguish the high end and fill it out.

I aimed for something like a DX7 sound by waveshaping one part against a sine and filtering it to get the "tine," and then leaving the other part a simple sine. It's playable, however it sounds nothing like the famous "DX7 Rhodes", it's harsher and it aliases more readily.

This is an original patch which actually uses the highpass filter(unlike almost every other sound I've done which uses LP or BP). The goal was to make something that gets the smooth character of gradually enveloped sines, but with a definite high end buzz, which is provided by a sawtooth as usual. Playable, but not quite what I had hoped for.

I felt like doing another detuned sawtooth patch, so I did one I've reproduced on other synths, the riff in Futurecop's "1988 Girls." It's a nice brassy, full sound when voiced well.

It's the "Jump!" sound, and it's accurate enough to start phasing against the original recording. I didn't play the actual riff, the keyboard doesn't have the range to do the correct voicing to begin with, but I do play some notes around the appropriate octaves and chords. For examples of the sound: http://www.synthtopia.com/content/2009/06/30/van-halen-jump-demo-oberheim-obx-a/

I spent a while on it, but I think it's kind of awful. Waveshaped square wave plus sine wave plus miscellaneous other stuff(filter, pitch etc.)

Sawtooth, downpitched, resonant low-pass envelope. Waveshaped for added punch. Demo is the Good Times riff roughly as interpolated in Rapper's Delight. I took some time and used a click track to actually get the rhythm almost acceptable but not really(ha, foiled by latency again).

It's just carefully shaped noise.

Over the past few days I've been improving oscillator and filter quality. Yesterday I improved the pulse waves by doing the correct form of additive synthesis on the rectangular function(instead of taking a square wave and awkwardly rescaling it). After I did that I looked into improving the tonal noise, which has always had inherent aliasing, being an oscillator based on a small single-cycle noise pattern. I decided, based on my success with oversampling elsewhere, to oversample the tiny initial waveform 4x, making aliasing much less present until you hit C-6 or so. In the process I discovered that I had made the wrong constants for the Blackman-Harris window that I'm using to oversample things, so the filter is a little cleaner now too. I also shrank the tonoise waveform to 32 samples instead of 64. The downside of doing this is that it's more "tone" and less "noise," the upside is that it performs better and it's more straightforward to modulate.

Today I made just about the simplest patch you can make with the tonoise oscillator: envelope the noise in and out. This gives you an approximation of Karplus-Strong style pluck sounds, only more metallic sounding.

These are pretty easy to make - two sawtooths and some pitch and filter modulation - and a lot of fun to play.

At first I thought I would try making a cymbal. This is even harder than making a hand clap, so after an hour or so I stopped and started noodling and ended up with this instead. Triangle wave used for the "tine" attack, 25% pulse for the sustain.

This is haaard to synthesize well. I "finished" it, started typing up this post, and then went back and spent another 20 minutes on it. The final thing is two layers of noise, filtered in different ways, both of them using the "fast sawtooth LFO" trick that makes it sound more like multiple impulses. A third layer might make it sound richer, but I stopped there. For a really good example of this style of synth clap see "Being Boiled" on Human League's Travelogue.
