Tranzistow 32/64-bit VST Synthesizer by HrastProgrammer

This page is about my Tranzistow Advanced Virtual Software Synthesizer with Additive/Spectral/Wavetable DSP Engine.

In global, Tranzistow (this is not a mistake - it is not "Transistow") is a virtual software synthesizer with 4 or 8 independent multi parts. Although it is (to some extent) inspired by Alesis Andromeda, Waldorf Q, Waldorf Microwave II/XT, Oberheim Xpander, John Bowen Solaris and Yamaha DX series, it has a unique sound and tons of unique features not found on any other synthesizer. Various forms of synthesis are supported including Additive, Virtual Analog/Modeling (VA), Wavetable (with classic, crossfade and full wave interpolation modes), two completely independent FM engines, Ring Modulation, Oscillator Sync, Vectors, Rotors (as in Solaris), various filter models (SVF 12/24dB, 6dB to 24dB Transistor Ladder with fully configurable poles, 24dB Diode LowPass Ladder, ...), Filter Chaining, Comb Filters, WaveShaping, freely drawable Contour Generators, exhaustive FX section including Chorus/Flanger, Phaser, Delay and Reverb units, etc, etc.

Short Description of Tranzistow Synthesizer [PDF file]

I developed Tranzistow for myself in the first place. My goal was not to (try to) emulate existing (hardware or software, analog or digital) synthesizers (although I was inspired by some of them) but to create something I can actually use in my own music, to master DSP/Assembler/Vector/SSE/AVX/AVX2/GPU/OpenCL programming, to refresh my mathematics knowledge and, last but not least - to have fun. As a result, the synthesizer is mostly unconventional, some features (which most users take for granted) could be missing or could look rather strange, user interface may not be everybody's cup of tea because it was designed according to my habits/needs, etc.

Tranzistow is a synthesizer for pure electronic artists, sound programmers, synth lovers and creators of true electronic music, it doesn't pretend to be anything else. So, if you need beautiful, unique, powerful and most complex synthetic electronic sounds of the highest quality - then you are at the right place. It isn't really aimed at keyboard players and, although it can be used for such duties, there are much easier ways to obtain the usual keyboard sounds. It is like buying a ultra-capable 4x4 offroad vehicle and use it for everyday driving - isn't it simpler and much more convenient to use a small city car to go shopping?

Starting with build 16.08.2016/1, Tranzistow is available on Linux in the form of 32-bit and 64-bit standalone audio applications as well as experimental Linux native VST 2.x libraries:

(see Linux section at the end of the above PDF document for more info about Linux version)

Due to various reasons which I will eventually explain one day (mainly - my irritance and disappointment with tons of hosts quirks and limitations which I don't want to tolerate anymore) experimental native VST versions are implemented as client/server combo where the client is a 32/64-bit VST .so library and the server is a separate 32/64-bit standalone Tranzistow synthesizer application.

Demo version is, more or less, a fully functional Tranzistow with the following limitations:

(*) No multimode and no multiprocessing - it is monotimbral, singlethreaded and only Part #1 with 16 voices of polyphony is available. External Control Interface is disabled as well.

(*) It loads the default patch on every start, so you'll have to manually reload all patches every time you open/reload a particular project.

(*) No ability to process external inputs through Tranzistow FX units, so it cannot be used as a standalone FX processor. External inputs can still be processed through the voice engine, though.

(*) Occassional noise and clicks/pops now and then, together with occassional missed notes. This is just a slight annoyance which won't have a big impact on the sound and won't disturb the "demonstration purpose" of the synthesizer, but will prevent its serious usage because you don't want to have clicks/pops and missed notes in your tracks, do you?

The package comes with almost 3500 of my own patches which can be easily browsed through by clicking on the "Browse" button located on the "Patch/FX" page. Those patches illustrate the way I work and the way I use synthesizers for, so they probably don't appeal to everyone. They also demonstrate the great range and variety of sounds Tranzistow can make and cover most of Tranzistow functionality, albeit some features are touched very lightly and just in a few patches.

Here is another bank with ~28000 Yamaha DX7 patches I reworked for Tranzistow QFM engine:

Some comments on Tranzistow:

"I will just say that it's certainly impressive the amount of work you've put into your projects, both the synths and the music! Incredible amount of output musically, and so I know you are passionate about it. And I must say, it's very excellent work! ... I see you did get some inspiration by my Solaris, which is a very nice compliment ... Let me say again how impressive your music production is! It's a lot of work, and beautifully done. I know when I first was making the Scope plugins, each time I would sit and play, sometimes for hours, through certain sounds that just seemed to inspire a musical phrase or a dream idea ... And so much of what is now being produced out there is, to be honest, boring to me. Just running a 16 step sequencer and adjusting filter cutoffs and so on - there's nothing 'skillful' about that, and there's so much of it going on now. But your music is so much more - very deep soundscapes! And the Solaris is very much that type of instrument, with a focus on pad sounds and textures, so I hear what you've done with your Tranzistow synth and I'm quite amazed!" John Bowen (the creator of Solaris synthesizer, http://johnbowen.com/)

"I wanted to reaffirm my total appreciation of the DSP programming work you have done with Tranzistow. I have many great synths (hardware, software, analog, digital) but nothing quite compares to the organic qualities that I have been able to coax from your brilliant synthesizer. You have done great work with Tranzistow, make no mistake about it. I can't thank you enough for this brilliant addition to my musical life."

"You can add me to the list of people who consider your Tranzistow one of the best software synth available. It is such a pity it is so obscure, more people should play with it. You deserve much more exposure. I really hope some company will acknowledge your talent and offer you the chance to implement your ideas in hardware."

"Modal should hire HrastProgrammer. I tried wavescaning on his Tranzistow synthesizer, it is by far the best software implementation i've heard so far. You can actually hear that crunchy graining thing where so many others fail."

"Tranzistow is slowly becoming a go-to synth for me. Looks like an 80s NASA control interface, sounds like a dream."

Some of old Tranzistow demos made by myself, mostly various drones, sequences and wavetable madness :-)
