128 Fixed Filter Bank v1.0
By Jesse Voccia


Reaktor A-128 Doepfer Fixed Filter Bank
Here is a reskin of Danie Scholz's A128, originally posted way back in 2003.

I have added a bypass switch and a input meter on the B view. I personally find these extremely helpful in discovering hidden new sounds within my same 4 ambient guitar loops that I have been beating into the ground for the last 8 years.

I have presented it here in a stereo layout ensemble. I highly recommend running a nice big fat drone from Plasma into these and then into my Roland RE-201.


loopers and floopers v1.0
By johann meier

Five effects with delays
Apologies if these are confusing, I set them up for myself and find them useful for mangling live guitar or synthesizer input with my FCB1010 as a controller. I am not good at writing help notes so I sort of didn't bother. As a quick roundup:

1) Frippertronics is not the other Frippertronics. It's three delay lines based on Michat's onehead tape echo that can feed into one another. That can get very loud. That's why you really want a foot pedal controller with this one so you can lower the master feedback.

2) Stop a moment fx--like a Reaktor pedalboard, i guess. There's a granular delay that I made, a reverb I stole from something Dieter Zobel did, a resonator, and the stock library ladder filter and the stock tube distortion. The order of effects and choices are completely configurable (it's just a cycle of three stacked macros) and there's some LFOs to modulate the whole mess.

3) Space echo + decks: I was trying to make a live looper out of the 8 deck from the factory library. It's easy to use and unlike the regular 8 deck, there's an FX send for each channel. Much more useful with a pedalboard so you can click on and off the various inputs as you're going. It currently has the brilliant new Space Echo from the UL which is the best delay unit in Reaktor attached to it, but you can use any FX you want, of course.

4) Stop a moment justtapes--isn't really like stop a moment at all. It's three of the magnificent live samplers from the UL put together, with some functions from 8 deck like tempo synch'd start and stop. Again with the LFOs that I use too much of.

5) Travelizer FX--if you open this up you'll see why I called it this. It really is travelizer with Michat's tape echo (again!) running into a grain delay. There's a filter and more LFOs and a couple of sequencers so you can get all crazy with it.

That's all I've got for now. These are hardly up to the standard of some of the other really outstanding contributions to the UL, but I figured someone might find them useful so here you go.


Metasonix F'ing F'er v1.0
By Jesse Voccia


Reaktor realization of Metasonix FF amp.
This is a guitar amp model. The major difference between this one and others is that this one has two channels that are active simultaneously and they have adjustable phase. Which allows for a less frequently used, but very interesting array of tones to be achieved.

The guts of this are mostly cannibalized from Heinrich Angel's excellent Twang series of ensembles. Thanks Heinrich!

Also, I have no association with Metasonix or Eric Barbour. I am borrowing his material without his permission or knowledge in a way that is not for profit or gain. Merely amusement. So hopefully he would be amused.

I saw this on youtube this morning and I got very curious of how it would sound. So here is my attempt at how something like this could work. The actual device is a custom made $5000 tube amp with 26 exotic tubes, used in exciting and dangerous ways. I haven't actually played though one yet (maybe sometime this week), and the specific details of how the actual amp is wired are hard to come by. After a few minutes of messing around with the dual channel-phase idea I discovered that I was on to something interesting.

Out-of-phase and phase-distorted amp tones were used extensively by Led Zeppelin (Houses of the Holy) and Jimi Hendrix and to a lesser extent The Rolling Stones during the golden era of pop music.

In the modern era bands such as Queens of the Stone Age and Nine Inch Nails are finding new ways to exploit phase cancellation effects on guitars and other instruments.

User Notes:

The B view is a mess, I will need to spend some quality time on it to make it tolerable. Sorry.

The master output level controls are the big chicken knobs on the B view. There are also some mid and treble shift buttons in the center area.

This thing is pretty noisy. There are noise gates for each channel, I don't think I used them on any of the presets. They are there if you want them. After messing around for a while I discovered that it was so noisy that it could be a sound source itself. By mapping keys on the piano keyboard to the silver switches and modulating the tone controls you can have a whole lot of fun.

The Silver Switches are to turn each channel on or off , and to turn the built in filter on each channel. The filter is multimode amongst the various reaktor offerings, with adjustable cutoff and resonance. Which helps with sustain and by creating helpful overtones.

Most importantly... the phase knobs are pretty much the key to anything interesting here. The slightest movement of them makes a big difference. I mention it because "I have a feeling there's gold in them hills."

If there is any positive interest in the Reaktor community in this ensemble I will finish the B panel, if not...


S240 Frequency Shifter v1.2
By Jesse Voccia


Reaktor realization of Bode Frequency Shifter
This is a reworking of Sean Costello's excellent Bode Frequency Shifter. The actual frequency shifting engine is completely Sean's work, I have added some other features that I wanted and some new skin borrowed from some Analog Systems manuals. The interface is still very rough, but I have moved on to other experiments, so this is as far as I am taking it.

Much like my Roland Space Echo experiment I feel like this is an effect that should be played like an instrument rather than to be left at a certain setting. I have mapped the mod wheel to the big dial because I think it should be in constant motion!

This thing sounds great to me on guitars and vocals. I have bundled it here with Martin Brinkman's excellent BassLine 303 style synth, but I intended it to be used as an insert effect. Bassline is only included here as an example.

Thanks to Jonathan Style for the 3D vintage knobs!



Mezmerizor v2.3
By Don Dailey


Mezmerizor is a sound machine an is an experiment in controlled randomness.
A remix of A-16X by Luca Capozzi, Melodian by Rick Scott, Echoperplex by Dieter Zobel with a Frequency Shifter thrown in for good measure.
UI by Don Dailey with Knobs by Jonathan Style.
Snaps by Don Dailey

I swapped out Luca's sample for various sample maps I had lying around. I had to keep them small to be about to upload here. Load your own samples and get a totally new sound machine. Try loading one of my EOS maps (here in the UL) They work great with this. Please experiment with your snap randomize control and play with the "freeze" button for some cool surprises.

Mezmerizor Two has an added Power button on the front panel and extra MicroTonal Scales.

v2.3 has notes now triggered by keys (added a Gate) and an AR envelope. I think I'm done :-)

Snaps dedicated to Chris R Gibson
Chris always leaves nice messages when he downloads my stuff and I really appreciate that. I get the feeling we have similar taste in strange sounds, so this is for you, Chris!



Frankenloop XII v1.1
By Peter Dines


Random-enabled MIDI monosequencer
The Frankenloop is a monosequencer in which you can either draw note sequences with the mouse, or play notes in from a MIDI controller. The "chance" table determines the probability that a particular step will hit or not.

The GlitchDevice+tv v1.0
By the Borg


glitch sequencer.
I made this along time ago a reinvented it recently it has a new interface and
of course my favourate block jammers
for mash up and the new glitch tv.

its great for idm,glitch,electronica,dubstep,and is mainly designed as a live tool having the flexability of two sample sequencers with lots of modulations ,btw there aren't any snaps as of the scene selectors. all comments a suggestments for improvements welcome

oh the pic is just a bit of art i made whilst glitching atari emulators with corrupt data.



pharmacy and contraption3 v1.0
By johann meier

flexible sequenced synths and samples
Two new additions to the contraption and missive set, plus some modifications that make missive and pcontraption2 a little better--your old snaps will still work with those, in fact, they'll work better.

PcOnTrApTiOn3 is a psychedelic rhythm synthesizer and sampler. CPU consumption on my machine is comparable to Sinebeats2. There are eight sequencers at the top which can be routed to serve as gate or pitch selectors for any of the six sound sources (so sequencer one can serve as the pitch sequencer for oscillator one, sequencer two can serve as the gate sequencer for oscillator one, etc.). The sound sources are blended FM oscillators pointed at one another as FM sources that can be cross-faded with samplers. This is much rawer sounding than the old pcontraption.

Don Dailey designed the snaps and they're really nice demonstrations of what this can do.

Thanks very much to theologiae for his excellent event table tutorial, and also thanks to Dan Battaglia, and Deiter Zobel for bits of advice and ideas that helped with this process.

I have had both of the PcOnTrApTiOn sequencers for quite a while, but i find i don't use them for live purposes at all, so now i've added Pharmacy, which takes the format of the PcOnTrApTiOn machines and makes it super simple. Just four oscillators, four sequencers, and some master controls. Still quite flexible.


Fourious 2000 1.5 v1.0
By Sandy Small


Additive Synthesis, too late for the millenium
I have taken the liberty of making a few tweaks to Paul Woodroffe's outstanding additive synth--he deserves all the credit here.

I have made the following changes--

-Fixed a bug in poly mode whereby two notes--the current one and the previous one--would sound with each keypress.
-Set all the controls to useful default values for initialization purposes.
-Hacked in a control to detune the overtones, based on the one in Sum Synth.
-Applied the detune control (in the master section) to poly mode in addition to unison mode.
-Added a more traditional waveform display (although I kept the trippy pseudo-3D display as well).
-Changed several presets as I saw fit due to some of my modifications.


Perc-FM4 Remix v1.0
By Don Dailey


Simple update of a very useful synth
A little remix of a simple FM synth I use a lot. I added a few FX and made a new face and a bank of snaps.

Thanks to Jonathan Style for the Knobs and Sliders.

note: lighted buttons are reversed (lighted = OFF) until I can fix that.
