DESCRIPTION

New in 1.9:
There are demo sounds for some of the new stuff. You can find them in the „demo of new features“ bank.

Overhaul of the „Supersaw Oscillator“. I found an interesting research paper from Alex Shore on the JP-8000 „Supersaw“, wich led to some modifications in my Supersaw Oscillator. It now consists of 7 Oscillators, (not 6 as before) and they come in three different flavors: „LoFi“ spares antialiasing and therefor has a rougher sound, „Super“ is built with primary oscillators (as before), and „Hyper“ adds another 7 oscillators on top, but these are impulse oscillators not sawtooths to add sheen to the top end. "Knack" key-triggers 3 Oscillators, the remaining 4 run free. This gives some impact to the attack.

Alternative envelopes with exponential attack
Most digital ADSR-Envelopes work with linear attack and exponential decay. Now you can switch the filter- and amp-envelope to exponential attack and control the attack slope. This removes some of the clockwork routine and feels a bit more "springy". I like it, what do you think?

Distortion
Inside the Beast structure there are 3 points where some kind of saturation or distortion is added and level is crucial to the sound: filter, amp and at the output. Filter and amp work polyphonicly, so there is no cross modulation between voices. But before the output-section is reached, all voices are added, so this distortion has quite a different effect. In the „Global“-Section to the left you now have access to „drive“ and „ceiling“ of this output distortion. Leave both knobs at zero to get the same sound as before. The „Drive Organ“ Snapshot is a good starting point for diving into distortion research. Besides the before mentioned parameters try „Filter Saturation“, „Volume“, „Sat Bias“ and „Highpass“. Each one has its specific impact on the overall sound.

New in 1.8: Still in search of the "perfect" sawtooth, I changed some highpass filters inside the saturation circuits. I also changed the behavior of the "impact"-section. It did a 3dB/octave rise over the whole Spectrum, to let sounds better cut through the mix, but it was overtly bright. Now it's 1.5dB/oct. I also added "sweetening"-style bass and treble EQs. They are neutral at the 7 o'clock position and fine around 12.

New in 1.7: Added a small oscilloscope view, inspired by the "minilogue"

New in 1.6: Did you know there's an audible difference between rising and falling sawtooth waveforms? I didn't until yesterday. And I'm still not completely convinced, but the falling sawtooth to me often sounds rounder and fuller than the rising one. The older bEAST Versions worked with rising sawtooth waveforms, this one produces falling ones. Is there a difference or am I hallucinating? There's a phase reverse switch in the mixer section, so you can make your own observations :)

bEAST is a virtual analog Synthesizer specialized in agressive and distorted Lead, Bass and FX Sounds. It is built around the Ladder Filter-Algorithm by Antti Huovilainen and Vesa Välimäki, Filter implementation in Reaktor Core by Salamanderanagram (many thanks!) The Audiopath is full stereo from the Oscillators on. For best results, run it at 88.2 or higher.
Though the Layout with Oscillator Bank, Mixer, ect. may look familiar, bEAST is not a Minimoog Clone. Have Fun!

This is indeed a beast! It likes to make dirty sounds and yet still has a lot of variety. Took me a while to start comprehending the gain staging(?) in this thing while running through the snapshots. Neat results of distortion types in various places here. Thanks for making and sharing this.

damm...havent had a all in one synth with a sound like this thats not hard on the CPU in a...long...long..time dude. nice work!

Now, that is a nice and fat sounding ensemble. Thank you Jörg.

Sorry, I was wrong. There's not just one high-pass in the output section - there is a cascade of 6dB/oct high-pass filters throughout the instrument, which where set to different frequencies. I have corrected this, the sawtooth waveform looks better now.

You are right, there's no DC offset at the output. The saw's shape is not completely determined by the Oscillators. Oscillator volume, saturation-bias and the cutoff-frequency of the output-highpass are also crucial. You get the "purest" sawtooth by setting the volume low, highpass at 2Hz and the bias to zero. The waveform will still look a bit "exponential". This is caused by the 6dB/oct highpass working at 2(!)Hz, and it's nearly inaudible.

Well my fault, i forgot the filter. Lowpass without key tracking leads to my described waveform change, nothing to wonder about. It's really just this logarithmic shape of the saw.

my thoughts about the sawtooths. - the anti-aliasing of the primary oscillators is not the best ^^ - the waveform gets a kinda square like form at lower frequencies and associated by that the waveform gets a dc-offset as well. is this a bug? i'm pretty sure that R5 did not show this behaviour

cool,a real instrument...somthing that is not a block...thanx 4 that... and great synthh by tyhe way!!!

Thanks for your comments on the up- and down-sawtooth phenomenon. I added a small scope view, just to be sure about the slope... and for the fun of it.

Ditto. I have allways heard the two sawtooth differently in a sound. Thanks for the update.

I hear the same thing regarding the sawtooth, really hard to tell tho if it's just my brains fooling me because they sound very much the same, I would describe it exactly as you said with the addition of warmer, which might be exactly the same thing as what you sense as fuller of course.

After some testing i must add and say that this synth is capable of producing both nasty, dirty, beuatiful,peaceful, fun, fat, thin, classy and warm sounds. You name it. Just take some time to create. Really good features to control sounds on this beautyful beast including the ramp and sweep controls. And you can also use lfo to PWM etc etc ... Quality.

Forgot. This beast can create some moogy sounds too. Just as the design. You Know.

Yes thats a beast. Thanks a lot. The snaps are not warm but dirty. Some say dirty is warm. No matter what this ensemble has great sound. I find your F A T P A D can create some warm sound. But that synth is not dirty as this beast. Your synths and your fx's kompliments each other. Thanks a lot.

These sounds aren't warm...the emulations are cold and harsh. Not musical...

the demo mp3 sounds awesome. however, the synth cannot be downloaded, please do something about it.
