Bootsy releases FerricTDS

Bootsy has released FerricTDS, a free tape dynamics simulation effect plug-in for Windows.

Bootsy FerricTDS
Bootsy FerricTDS

Inspired by the smooth dynamic shaping capabilities of some high-end reel-to-reel tape recorders, this plug-in simulates three of the most distinctive and much appreciated sonic effects generated by these devices:

  • DYNAMICS – gently shaping the overall dynamic response
  • SATURATION – adding extra harmonic-related content
  • LIMITING – controlling peak performance

FerricTDS features

  • Performs gentle audio dynamic treatments.
  • Masters difficult to handle audio material.
  • Adds extra harmonics and saturation effects.
  • Controls outgoing audio peaks.
  • State-of-the-art digital signal processing.
  • 4x oversampled core algorithms.
  • Performance-critical parts are written in assembler.
  • Completely SSE-optimized.

FerricTDS is available as a freeware VST effect plug-in for Windows PC. It is part of the KVR Developer Challenge 2009.

de la Mancha releases FMMF

de la Mancha FMMF

de la Mancha has released FMMF, a 4 operator FM (Frequency Modulation) synthesizer plug-in for Windows, written as an entry into the KVR Developer Challenge 2009.

The waveforms, algorithms and envelopes in FMMF are all shown graphically, with the envelopes allowing dragging of nodes and clicking to change contour. Special attention has been paid to the envelopes to allow you to customise them in many ways, such as the number of stages, the contour of each stage, sustain and repeat points and tempo-sync. There are envelopes for the volume of each operator, the pitch, and the effects section (filter, distortion and delay) all with velocity and key tracking. Further modulation comes in the form of LFO’s for the pitch and effects section, with many LFO waveforms available, including my favourite, randomising.

For further sound design potential you have a low pass filter, a multi-mode distortion and a flexible delay (with comb delay option). An arpeggiator let’s you add even more movement to create rhythmic sequences.

FMMF features

  • 4 Operator FM Synthesis instrument with 17 FM algorithms.
  • 11 different waveforms per operator, with note sync option.
  • 7 Multi-segment Envelopes (up to 32 stages) for amp, pitch and effects modulation.
  • 3 LFO’s for pitch and effects modulation.
  • All envelopes can be free or tempo-sync, each stage can have it’s own contour.
  • Envelopes can have user defined sustain and repeat points with flexible locking and zeroing options.
  • LFO’s can be free or tempo sync, with 20 waveforms and phase & note sync options.
  • Each LFO has it’s own ADSR envelope.
  • Arpeggiator with 6 modes and adjustable tempo-sync, note length and octave range.
  • Resonant low pass filter with key and velocity tracking, can be modulated by envelopes or LFOs.
  • Distortion effect with 18 flavours, can be modulated by envelopes or LFOs.
  • Delay with comb delay option, size, feedback and damping, modulated by envelope or LFO.
  • Harmonics can be adjusted from 1 to 256, with limit on frequency beyond Nyquist.
  • Polyphony adjustable from 1 to 16 voices.
  • Portamento time.
  • 64 presets by brian botkiller covering many styles.

FMMF is available as a freeware VST instrument plug-in for Windows PC.

xoxos releases Friction and Populus free

Related: , , , , , , Posted in news on Jun 22, 2009 - comment 0 comments

xoxos has released Friction and Populus as freeware.

The commercial VST Friction won a poll at and is now freeware. I’ve chosen to include Populus

xoxos Friction and Populus

Friction is a physical modeling synthesizer designed to be applicable to a range of emulative tasks, and is suitable for budget foley production or experimental music.

Populus generates MIDI sequences using an algorithm modeled on biological behaviour. The measure is treated as a ‘year’ and note events are determined by parameters describing the ‘life cycle’ of each note.

Visit xoxos for more information and links to download Friction and Populus.

How to use:

  1. load Shaker Maker in the insert slot of your audio track.
  2. load a drum loop or any other rhythmic audio file to this track.
  3. choose one of the 16 prepared shaker sounds, or shape your own shaker.

xoxos wins KVR Developer Challenge 2007

Related: , , , , , , , , , Posted in news on Nov 02, 2007 - comment 1 comment

The KVR Developer Challenge 2007 has its winner: xoxos (Rurik Leffanta).

xoxos took first place with Sounds of Nature, a collection of VSTi for emulating common natural sounds – wind, rain, thunder, songbirds and insects.

Well done Mr. Rurik! I did not vote myself (lack of time to check all the entries), but even if I wouldn’t have put xoxos’ entry first place, it is a well deserved win. xoxos has released tons of cool freeware plug-ins over the last few years, more than doing his part in the community.

Second place goes to Mucoder’s Hypercyclic, an LFO-driven MIDI arpeggiator. I guess I will have to take a better look at this… First time I tried it I couldn’t get it to work really, but it seems useful enough.

UGO‘s synth The Element of Surprise gets third place. This one was on my original list of plug-ins I was interested in. It looks a bit simple but it can do some really nice sounds. If you like randomize stuff like I do, be sure to check this one out.

I’m glad to see de la Mancha & Sink’s multi-effect VST plug-in truc up there as well (4th place). Out of all the DC plug-ins of this year, I think truc will get the most use. It’s great for crazy FSU type effects.

Check the KVR Developer Challenge page for the complete list of entries.


Onzekerheid and Boards of Hollandia

I’ve added two new tracks to the KVR contest entries page.


The theme for the August contest was Form. The idea was to compose a piece that falls into one of the following musical forms:

  1. ABA
  2. ABAC
  3. AABA

See if you can figure out which one I chose! This is my first entry with vocals (I recently bought a cheap Akai mic at a junkyard sale for a few bucks), and they’re in Dutch in case you don’t know what you’re listening to. I wasn’t too impressed with my vocal performance myself, but it’s common knowledge that poppy songs with vocals tend to do better than instrumentals, so I ended up in 4th place out of 40+ entries anyway.

Boards of Hollandia

Boards of Hollandia

The September theme was YRUme (why-are-you-me), in which we were supposed to emulate a band or artist. Covers weren’t allowed so the difficulty was in creating something that sounded like someone without actually doing one of their songs.

At first I though I’d do Dinosaur Jr. or Sonic Youth, but as I was on the beach in Tunisia most of September I decided to do something less time consuming.

I started out with some pads in Oatmeal, put some LFO on it and figured I should have a go at a BoC type piece. In the end it didn’t quite come out gritty enough, but I’m pleased with the overall result. It didn’t rate well at all with the peeps at KVR, getting just a few votes and placing somewhere in the middle of the results list. There were a few amazing entries though, so I’m not disappointed with my score.
