Quilcom SIM-SHENG 0 (0)

The Quilcom SIM-SHENG is a plugin designed to simulate this ancient class of Chinese mouth organs.

Click on the picture to download the zip which contains 32 and 64 bit plugins and a 32 bit plugin for Windows XP. Also included is a Background info folder so you can learn about the instrument, and a User guide for the plugin.

I always include the fsm file for my plugins which isn’t needed for the plugins to work but is there if you want to download FlowStone and look at the workings and maybe modify it, or use bits and pieces for your own projects.

Have fun!

Quilcom SIM-CARNYX 0 (0)

A Carnyx is an ancient Iron Age Celtic war horn used to intimidate the enemy in pitched battles, and it’s not very “musical”. It is, however, fascinating… to me anyway!

There’s lots of info in the Background info folder and User Guide if you would like to know more.

The download includes 32 and 64 bit plugins and XP compatible ones, with and without audio input.

Also you get the FlowStone schematics (not needed for the plugins to work). This means that if you buy FlowStone you can open, examine and alter them as you wish.

Click on the picture to download it, load it up and open all your windows and have fun really upsetting your neighbours!

RMI-EP by AM Music Technology[x86][VSTI][Win][FREE] 0 (0)

MI-EP reproduces the vintage analog electronic piano from US manufacturer, Rocky Mount Instruments Electra Piano, produced from 1967 until 1980.

The sound engine of the RMI-EP is a software emulation of the real analog oscillators and filters used inside the original instrument. The RMI-EP implements the same presets and controls that you can find in the real instrument. Furthermore there is also a effect sections that includes Reverb, Phaser and Chorus.

Any configuration of the electric piano is storable in up to 128 programs and can be reloaded through midi program change. All the controls can be handled through midi control change messages.

Inphonik PCM2612 Retro Decimator Unit v1.0.1 x64 VST AU AAX WiN MAC LiNUX [FREE] 0 (0)

The sound of the machine
Meet the PCM2612 Retro Decimator Unit, a bitcrusher effect plug-in with a distinctive legacy. Based on the work we made on the RYM2612 Iconic FM Synthesizer, our tribute emulation of the Sega Genesis sound chip, the 8-bit decimation is inherited from the FM synth’s PCM playback feature, packed in a simple and compact effect unit. Bonus: it’s free!

Two form factors in one
You can choose from box to rack graphic user interfaces.
The box GUI is suited for vertical displays while the rack GUI is logically at ease with widescreens.

Digital is the new vintage
Modern music styles that are composed in a digital environment evolve in a paradox: powered by highly capable and transparent digital converters, they rely on effect simulations to add imperfections and get a vintage soul. Either in an analog or digital fashion, the induced sonic flaws give charm and character to a sound signal that’s otherwise too perfect or too cold.

Is digital decimation of the ’90s the new vintage? We think it is!

Key features:
• Free!
• 32-steps scalable 8-bit decimation
• Dry / Wet level knob
• Stereo / Mono switch
• Switchable output filtering between Legacy (modeled after the Sega Genesis Model 1 amp output circuitry) and Crystal Clear (purely digital)
• Graphical interface scaling options (1x, 1.5x, 2x)
• Switchable graphical form factor (vertical box or horizontal rack)
• Low CPU usage
• Our first native Linux and Apple Silicon plug-in

Welcome to the retro future
You may remember (if you’re as old as we are) how hearing an audio sample in a videogame during the 90’s was simply out of this world. It was nothing less than an exciting avant-goût of the future, and the overly-presence of the 8-bit resolution and aliasing due to modest sample rates couldn’t mask the amazement. Even more, it was associated with the delight of accessing new voices and sounds on our favorite games. The PCM2612 brings back these memories when applied to voices or drums parts.

DDMF phi-L Audio Tube Preamp v2.0.2 x64 x86 VST VST3 AU AAX WiN MAC [FREE] 0 (0)

What is it?
This tube preamp emulation has been developed Philipp Bulling as a thesis work. Philipp has been offering the plugin in VST format for some time on his own website. He has now moved on to new areas for some time already but didn’t want to let down his users. Hence, DDMF took over the code and will continue to offer the plugin as freeware, with the intent to further improve it and maybe add some more bells and whistles in the future.

The plugin is very unique in the sense that it gives you full control over all aspects of the modelled circuit. All values of all the capacitors, resistors etc. can be tuned by the user. Here is what Philipp had written on the original page.

AbstractSince the sound of an analogue tube amplifier has always exerted a strong fascination, electrical circuits with tubes play a certain role in the world of audio engineering up to now. On the other hand, audio technology becomes more and more digitised. In many cases, digital models emulate real devices in such a way that differences in sound are hardly audible. In this work a model is developed which is able to emulate the typical sound of a tube amplifier on digital devices. Here the main focus is on preamplifiers with triodes, since they have a particular influence to the sound.

Based on the physical properties of real tubes, a tube model is developed first. This mathematical model includes results of theoretical studies as well as analysis of data sheets. The model is then used to implement an entire amplifier circuit. In addition to the tube itself amplifier circuits contain several passive elements. In the domain of digital signal processing the latter are described by finite difference equations, which are solved recursively.

The resulting algorithm is finally implemented as an audio plugin in order to examine its tonal properties. The behavior of the digital model corresponds satisfactorily to real amplifier circuits. Important sound effects of analogue tube amplifiers can also be attested to the digital model.

Diode modelThe first step was to develop a triode model, based on the characteristic curves of real tubes. In theory, the characteristic curve of a vacuum tube is described by Langmuir-Child’s law. However, it was quickly realised that compared to real tubes, this law is not accurate enough. So a new model has been developed. This model describes a triode as a mathematical function. With the model, it is possible to compute the plate voltage (Upc) as a function of the grid voltage (Ugc), depending on the working resistor (Ra) and the supply voltage (Ub).

The following graph shows this function for a 12AU7 triode with Ra = 10k and Ub = 250V:

Circuit modelingBased on this model, a plate follower stage was implemented.

Cathode biasingIn this circuit, cathode biasing is used to adjust the bias point of the tube. This is realised by a resistor (Rc) and a capacitor (Cc), placed between the cathode and ground. The effect of cathode biasing can then be modeled by a simple first order RC low pass filter, with Ic*Rc being the input of the filter, and the cathode voltage (Uc) being the output.

If the input signal jumps for example from 0 V to 5 V, the cathode voltage follows quite similar to the step response of a RC-low pass filter:

Signal limitingThere are two reasons for signal clipping in this circuit. The first one is caused by the tube itself. If there is a high peak at the negative half-wave of the input signal, the tube can’t amplify the signal anymore since the flow of current is completely cut-off. Thus, the positive half-wave of the output is clipped. This effect can be intensified by a more negative bias point.

Here the bias point of an 12AU7 is at around -12 V:
DDMF phi-L Audio Tube Preamp v2.0.2 x64 x86 VST VST3 AU AAX WiN MAC [FREE] screenshotThe second reason for clipping is caused by grid current. High peaks of the positive half-wave of the input signal make the grid voltage positive compared to the cathode voltage. In this case electrons are attracted by the grid. The grid current causes a voltage drop at the internal resistance of the previous stage, which limits the input signal. The following figure shows the effect. The grid voltage is obtained by shifting down the input signal (Uin) by the cathode voltage (Uc). In the upper picture the maximum grid voltage (Ugc) is ~ 0 V compared to the cathode. Hence, there is no grid current. In the lower picture the input signal has an amplitude of 10 V. At the positive peaks of the input signal the grid voltage rises above 0 V (compared to the cathode). The grid current begins to flow and clips the grid voltage.
