by rick scott

Pasted Graphic 5

Rhythmicizes and thrashes samples beyond recognizability.
Instructions on panel.
In a nutshell: Randomize (press Q), play (big XY pad), randomize, play, over and over,
until the Gods of Chance grant you something worth listening to.

Sekwarium III
by Dieter Zobel

Pasted Graphic 2

very simple step sequencer

with MIDI output for using as a VST - instrument
in your DAW or for driving synths in
Reaktor. I think that detailed descriptions are unnecessarily.
Just play with it.

I just add some features:
Basic note selector: Add the Rec Mod (assignable scale and note key per key)
Adjust this in the New Section
-Glide Mod: (1 actual / 1 AD Env)

Snapshots for the Allegheny Modular
by Michael Stocker

42 (answers everything) new sounds for the Allegheny Modular (Version 3.0).

The original Ensemble is here:

Thanks to Christian Huygen for putting everything into one huge modular,
to Herwig Krass for the fantastic Modular-X framework
and most of the modules and to all the other builders that contributed.

Please Note: Some of the "self-playing" presets might soiund strange.
In this case please stop, reset and restart the Midi-clock.



Accelerator 1.1.2
by mosaic_

Pasted Graphic 6

This is a synthesizer specifically geared toward drum sounds.
Kick, Snare and Clap synths, alongside Metal, Noise, Percussion and Cowbell engines,
produce a plethora of distinctive and customizable sounds.
In lieu of a sequencer, every engine can be edited and mapped to different MIDI note ranges.
Tuned percussion can be played across the keyboard with ease.

Alternatively, open up the recorder and turn your sounds into samples.
With the click of a button and the press of a key,
your drum sounds are captured and are ready to be exported as WAV files.

Ten kits are provided to get you started, ranging from clean and punchy to massively distorted. Enjoy!

1.0.1: initial upload
1.1.1: fixes a minor bug in the master tuning, removes a small GUI mismatch between the A and B panels,
and adds 18 new snapshots: 7 standard drum sounds and 11 tuned synth sounds.
Each one uses only a single sound engine (to save CPU) and makes a good starting point for new sounds.
1.1.2: GUI update; also adds an internal instrument "*Accelelerator MIDI In"
to which a sequencer can be routed to trigger all the drum engines,
got rid of superfluous outputs which caused issues in DAWs.


Infrastructure 1.1.2
by mosaic_

Pasted Graphic 7

This is a fairly simple synth with a versatile oscillator section and a characterful filter.
A spreadable saw, a variable-width pulse, a smooth sub oscillator,
and a filtered noise source are sent through a saturated feedback filter.
Envelopes, LFOs, and various expression controls are available to modulate and morph the sound.
Then the output is routed to a warming distortion, a stereo chorus, a feedback delay and a lush reverb.

Over 120 snapshots are included: mostly basses, leads, and pads,
with a few other sounds thrown in as well.
And a simple, clear layout makes it easy for you to create your own sounds. Enjoy!

1.0.5: initial release
1.0.6: added voice panning, fixed a few GUI bugs (existing snapshots are still compatible)
1.0.7: reduced clicking when when velocity decreases between two notes in Mono and Unison modes
1.1.1: fixed delay timing bug, added 35 new snapshots, added subtraction mode for band-reject/inverted filter responses,
added extra 2-pole lowpass available on filter, and added increased spread options for saw oscillator
1.1.2: GUI update


Redux 1.0.5
by mosaic_

Pasted Graphic 8

Redux streamlines the ideas in Infrastructure into a leaner, more efficient package.
The CPU usage has been cut in half, and the modulation system has been overhauled.
The oscillator and filter sections now allow for greater control, with improved waveform selections and new 6-pole and notch filters.
The result is a versatile, user-friendly, and compact synthesizer capable of both classic and modern sounds.

There are over 100 included snapshots to get you started.


Roland SH1000 emulation v1.8
by stuart pryer

Pasted Graphic

The SH-1000 is an emulation of the Roland SH-1000 synthesizer first released in 1973
and which was Roland’s first synth.
Its successor was the SH-2000 but that was designed to be more of a preset instrument
and had far less flexibility.
The SH-1000 was used by Vangelis, Blondie, The Band, Jethrow Tull,
The Human League and Eddie Johnson (Roxy Music) as well as many others.


Selector Osc 3.0
by Thomas Medes

Pasted Graphic 9

I took my old Selector Multi-Ramp FM ensemble and beefed it all to hell.

Old version can be downloaded here -->

For 3.0 I have added:
An interface!
Another modulation type (RM).
3 LFOs + a Vibrato module.
Filter with many filter types to choose from + 3 lfo inputs.

Created ADSR envelopes for the following:
Shape modulator's detune/spread
FM's amount AND fm's detune/spread
RM's depth mod
Filter's depth/env mod

The ensemble now includes a phaser/flanger and a nice little reverb.

The waveform can be drawn either by using your mouse on the wave constructor's display
or by using the knobs underneath it.

The 3 lfo inputs in the Filter section allow you to determine how much of each lfo's signal
will be allowed in and what math processes they will be subjected to before affecting the filter.
Each lfo input can be set to "x"(no change) "-x"(inverted) "rect"(rectified) or -rect(inverted rectified).
The two parameters they can effect are the filter's cutoff frequency and the filter's envelope depth.
The knob "LFO>CUT" and "LFO>ENV" make the final determination
as to how much those two parameters will be modified by the LFOs.

The shape mod section allows you to modulate the values of the wave constructor
in a manner similar to how both FM and RM modulate their carriers.
The shape mod modulates the values from the constructor at rates that match pitch intervals of the note
you are playing, thus wobbling the shape's 10 values cohesively which creates new character/timbre.

Wavetables, Sampling, 8bit sound ability

The monophonic three-64 synthesizer is a blend of the sound associated
with 8bit home computer devices and the clean layout and structure of the mini-moog.
The instrument can produce many of the hallmark sounds of the 80s computers
and with the ring-modulation and custom waveforms of many more.
Users can either use the preset waveforms, draw their own,
calculate them with the wave-combiner or use the built-in 4bit sampler.
The waveforms are very crude and have some unusual features and charm.
Especially the triangle waveform has many more overtones than intended.


Three wave table oscillators.
- Each oscillator has three basic wave forms: Triangle, Saw, variable pulse
- Preset waveforms are calculated, not stored
- 23 steps per period
- Each oscillator allows for custom drawing of waveforms with recall
- Sync
- Ring-modulation
- Pitch modulation
- Pulse width modulation
- Oscillator three:
Can function both as a 4bit sampler and a wavetable oscillator
Can be taken off the keyboard tracking for LFO
Has a waveform calculator that allows to mathematically combine waveforms:
- Hold and drag the symbols under the waveform window of OSC3 to change calculation
A smoother can be applied to the waveform

4 bit sampler.
- Loop length, sample start
- Sampler is fed through Ext. in gain
- Sampler starts recording once it receives a signal ->Hold record and feed signal

- Choice between white noise and pseudo-random pitched noise

- Pitch modulation with fixed intervals (m3,M3,P5,8ve)
- Envelope to pitch
- LFO (Osc3) to pitch
- Seamless fade from Noise to OSC3 for modulation bus
- All modulation can be fixed or enabled with the mod wheel

- 12db HP,BP,LP Notch
- Resonance


- ADSR, hardwired to Filter and VCA, respectively
- Filter envelope can be routed to modulation bus


- The PWM works best with the pulse waveform,
although it is available for the other waveforms. In combination with other waveforms
it can produce something in concept similar to a pulse-saw.

This instrument is intended for a quick and dirty way to 80s 8bit sounds.
This synth is not a 100% authentic reproduction of the SID or other 8bit sound chips.
For the purpose of absolute accuracy there are other true and amazing emulations.
This is primarily a fun hands-on synth for leads and quick sound effects.
