Cloud 9 Reverb v1.2
by Bryan Lake


Improved algorithm with new features and a snug interface.

I spent several months trying to nail down the perfect algorithm. Well, this isn't it, but it's the best design I've managed to come up with thus far. It's predecessor is more economic, hitting the ceiling at 12% CPU, while version 1.2 pushes 16% with the "Signal Gate" module engaged.

In addition to a slightly more complex feedback network, Cloud 9 v1.2 features separate diffusion controls for both Early and Late Reflections, an "Offset" control that basically staggers the predelay times from left to right, which produces more realistic early reflections.

"ER Damping" is somewhat self explanatory, with controls for "Low", "Mid" and "High" Shelf EQ modules, whereas "LR Filter" is just a simple 1-pole Highpass and Lowpass filter in series.

Another interesting feature is a "Dry/Wet" knob, bypassing the feedback network completely when turned all the way down, literally switching off the entire reverb effect, allowing only the dry signal to pass through unaffected.

The "Signal Gate" module has three modes, the first being the simplest: The incoming audio is translated as a gate signal with a linear amplitude value of 0-1 that triggers an Attack and Release envelope throttling the incoming (unreverberated) dry signal.

When "Tail" is engaged, the envelope attenuates only the outgoing (reverberated) signal. When "Choke" is engaged, the entire signal chain, both dry and wet, are manipulated by the envelope, allowing for volume swells when the "Hold" button is either manually pressed or triggered by your midi keyboard's sustain pedal.

These parameters allow for a more dynamic control over the diffuser chain, resulting in a more useful and versatile reverb tailored for live performance and production, with a manageable size and tolerable CPU hit.

ARP Quadra 2.3 Skin
by Sylvain Stoppani


Update of the Quadra 2.2 ensemble by Mike Nowak with new GUI

Nothing new apart this nice GUI design and skin. The ensemble by Mike Novak get closer to the original instrument.
It look more fun and organized like this. Because the original design is huge, the commands of the synth are divided into two panels, so you need to switch A/B :



Auralis Modded
by Jim Hurley


This was built with Reaktor 5.9.1.

Auralis was released about 11 years ago by Kristian Thom; it has been my favorite ensemble - indeed it was the main reason I fell in love with Reaktor.

I did a few changes and updates for it, mostly a lot of little things, and I tried not to change it's impish, quirky nature.

The major sonic change was that I replaced the delay lines in the waveform oscillator with diffuser delays. With diffusion at 0, they are just simple delays, as in the original.

I changed some of the effects: the EQ was unchanged, the limiter was updated with a compressor from the NI library, the reverb was replaced with micro space from the NI library, and I added a delay and phasor from the U/L. The effects are processed in the top-down order you see on the panel. The effects consume no CPU when shut off.

There were many small changes - randomizers from rachMiel, a snapshot change muter from Dietrich Pank, a snapshot breeder from Colin Brown, and the EZ FFT display from the U/L.

I also added a waveform display, added comments here and there, simplified some of the internals, and tweaked a few things. Everything should be commented internally.

There are over 500 new snapshots made just for this ensemble. The snapshot names are not meaningful, it's hard to come up with 500 names, so a lot of them are monsters and fantastic creatures. The snapshots are not in any particular order - mostly the order I made them - so some good ones are near the end as I got better. Most of them were made using Colin's snapshot breeder, finding good candidates and tweaking the parameters. All of the snapshots were made for the Random note player - I didn't set up any for the keyboard, so you will need to tweak that envelope if you 'play' Auralis.

I also upload it in two forms: one as a solo ensemble, the other is identical but includes a bank of extra ensemble snapshots featuring the rachToys ensemble from the U/L. The rachToys version will only be feasible if you have a powerful CPU - it uses about 33% CPU at 48kHz on my 4.3 GHz system.

If the solo instrument is still too CPU hungry for you, disconnect the EZ FFT display.

There remain some bugs: the gieger module used in the random note player sometimes takes a while to start up; the snapshot breeder modifications I made sometimes generate an event loop error; and the rachToys effects also sometimes take a while to start generating.

Synth1/NordLead style synth completely controllable with BCR

I wanted to have a simple and effective synth that I can completely control from my BCR2000 without touching the mouse (including FX). The concept is based on the Synth1 VST by Daichi, which is based on the Nord Lead.
So it's basically a quite simple Nord Lead emulation without the multi-effect and arpeggiator, but with unisono for oscillator 1 and slightly enhanced features.

The effects are taken from "herw modular x framework" by Herwig Krass, the drive function of the filter is from "Numalik III" by pierre-andre soulier.

Skin templates for your BCR are included in various formats, as well as the sysex file and links to the original template I used and a working freeware editor for the BCR2000. If you can't use the sysex file for some reason, you can use factory preset 1 and only have to change the function of some buttons to cycle through the according options.

V1.4 features:
- 2 main VCOs and one Sub VCO
- VCO1 has Unisono and FM, FM can be switched between linear frequency modulation and pitch modulation in semitones (FM/PM)
- VCO2 can be ring modulated and synced
- an AD mod envelope and two LFOs can modulate a series of targets

Unisono of VCO1 can now be switched off, the detune knob then just detunes VCO1 in cent. I hoped this would save a bit of CPU, but it doesn't make too much of a difference... might be useful for 3-osc-type-sounds.

I have set sample and control rate to the maximum, if it is too much for your CPU you might want to turn it down, but it will seriously destroy some snapshots (on others you won't hear a difference)


by Brian Lake


New and improved! With extra modulation targets...and glide!

I really spent some time on this update. I added a "Random" feature in the PWM module that toggles on the frequency modulation for each of the eight Sine Sync oscillators, allowing for a slight phase variation between each sine wave. The "Reset" button snaps them back together at a phase value of zero.

I've also added some additional modulation targets within the "4x LFO" macro with On/Off switches for each target: FF = Filter Frequency, FV = Filter Velocity, DS = Detune Spread, SS = Stereo Spread.

And last but not least, I've included Chet Singer's Linear Fingered Portamento labeled "Glide" with a simple On/Off switch and a horizontal fader that goes up to five-hundred milliseconds ... and I made a small handful of snaps just to fuel your inspiration.

KorE ms2x
by Andreas Sandberg


Ms-2x with reworked skin

First of all: I take no credit for building this synthesizer. It's all and all the old ms2x from the legacy library. However as an owner of a certain synthesizer of note, I found it compelling to dress the old sucker in a reworked skin, just to get a more authentic feel. The Solar-x original in the legacy library is a great synth in itself. The whole idea grew as I opened up the ensemble and started comparing it with the patching capabilities of the original ms20. I found out that the ms2x is a faithfully baked cake that pays homage to the original as far as You can with a VA. They even put the old patching examples of the original ms20 manual as snapshots. I just couldn' t resist the temptation...


Morphable Sine Bank x4 1.2
by Bryan Lake


Morph between 4 Sine Banks: 2 left, 2 right

A simple idea, really. I wanted to implement the same sort of "SpectroBlend" feature that u-he Zebra2 has built-in to its powerful oscillator section. Well, this is not the same thing, but I'm happy with the results. Morph between 4 Sine Banks: 2 left, 2 right. You can morph between each sine bank manually, with the "Morph Env", or use "Morph LFO" with a "Random" control that does what it says it does. It's not going to change the world, but it'll make some interesting sounds I can use in my projects, and hopefully yours as well.

(IMPORTANT NOTICE: I updated the zip file containing a newer version of MSBX4 featuring an option for the "Morph Mode" switch to enable XY control of the morphing between Sine Banks, which you can see in the screenshot.)

Update includes a Pro 52 resonant lowpass filter with assignable XY controller and an LFO with modes for "slow", "medium" and "fast". I also built a rather inexpensive reverb algo that (in my humble opinion) really makes this ensemble shine. Tops out at about 34% CPU (for this PC user) with the reverb on. Personally, I think it's worth the hit :)

It's a more popular further dev version of SoundScapes for Generator 1.56+, adapted to Reaktor 5.9
Panel A and B are different.
Pataphysical parts by -pa. Panel elements by Jonathan Style. Partly randoms idea by leboz [KraftStrom]. Two helpfull macros extracted from Zobels KraftStrom [Smash fold back + Random to all]. Trace seq based on snap seq by Chet Singer, it's pata controlled.
mostly harmless - except:
Be careful to adjust the base of resonance; it's outside of [Lazy].
try to load longer waves in maps, each slot 16 samples and start the clock for select pata trace
