1-Toast

This is a single oscillator synth voice modeled after the 0-Coast from Makenoise. Unlike the 0-Coast, there is no normaling in Audulus so the basic patch in preconfigured in the download pack, or you can use the above image as a reference.

From left to right there is a clock with variable duty cycle and a random modulation generator which can be used to create stepped random modulations. There is an oscillator section with three outputs, triangle, square, and overtones. The oscillator also has a playable pitch knob (default tuning is knob setting .4414), ‘AC coupled’ linear FM, and a wave shaping/folding section modeled closely after the 0-Coast. The slope section is either an attack decay envelope or a variable slope LFO which is often used to modulate the multiply section of the overtones. The Contour section is a simplified ADSR with linear to exponential shaping. The last section is a two channel mixer, which is typically used to balance the triangle wave with the overtone wave, which runs into the dynamics section which is both a volume knob and a low pass gate, which usually receives modulation from the contour section.

When I uploaded this to the forum, I made a ‘fun pack’ with the 1-Toast as well as chopped up versions of the sections that could be used as modules as well as a no-svg version of the default patch. I thought I would include it here… but I am through with taking screen caps of controls :stuck_out_tongue:

A blast from the past! (Well the recent past anyway :cowboy_hat_face:) A definite classic in the making. This Audulus re-creation has much of what made the original so appealing. A non-traditional approach to sound generation, a useful collection of generators and modulators, and an appealing UI. What’s not to love! One of your better efforts (although not the only one by any means).


#4

Thanks sooooo much :star_struck:


#5

My favorite Audulus synth voice! :musical_keyboard:


#6

Thanks for creating this. After bazilion years working with East-coast style subtractive synths, this and Bimini Road’s livestream showing off Rasmus have me very interested in West Coast style synths. While I really enjoy 1-Toast, I recall seeing a comment by you somewhere that you have some thoughts about how it might be programmed differently to be closer to the 0-Coast in sound.

I hope you’ll think about releasing a patch that implements those techniques.


#7

I think the major improvements will come when I can normalize the signal flow inside the 1-Toast, which I think will have to wait for Audulus 4. But thanks for the kind words :sunny:


#8

I look forward to it!


#9

Will those changes give 1-Toast more of the ‘in the face’ waveshaping that the 0-Toast has?

I have a question about the ‘compat’ 1-Toast Default’ module in the fun pack – the one on the bottom right. Does the slope have any impact when it isn’t cycling?

I am a total newb and it is taking me a while to get a hang of analyzing patches.

Thanks so much for your great creations.


#10

A little bit. The 0-Toast mixes the slope signal in with the oscillator past 2 O’Clock on the timbre knob. Also, in A4 I can use samples of the 0-Coast waveforms rather than approximations, which should enhance verisimilitude. The same goes for the non-linear response of the wavefolder.

That said, I did try to emulate the 0-Coast I have in my possession as best I could. Of course, as time goes on and my understanding continues to improve hopefully so too will my modules :slight_smile:

No, because that’s the default for the 0-Coast.

Thanks for taking the time to play with them :smiley:


#11

Thanks for the clarifications. I need to study the 0-Coast manual and some of the posted patches to understand it better. I am new to the West Coast/O-Coast paradigm and appreciating the sounds that the architecture unleashes.

I’d love to hear some of the music people are making with these modules.


#12

Audulus makes appearances at some level in most of the songs on this album.


#13

It’s a great album! :cowboy_hat_face:
