Synchron Player

Synchron Player free rompler by Vienna Symphonic Library (VSL)

Synchron Player is a free rompler VST, Audio Unit, AAX plugin developed by Vienna Symphonic Library (VSL). Compatible OS(s): Windows, macOS.

The Vienna Synchron Player is a dedicated sample player with an audio engine built from the ground up. Combining multiple microphone signals with a wealth of note variations and velocity layers for each articulation may quickly lead to a quite heavy voice count and CPU load. The Vienna Synchron Player comes with the most powerful sample playback engine, featuring unprecedented streaming performance while providing a new level of ease-of-use.

Innovative algorithms result in utmost realism and expressiveness: You may play short notes, long notes with various attacks, legatos, scalable vibrato intensities and note repetitions intuitively just by moving one or two preconfigured controllers, with a minimal need to switch articulations manually. The Vienna Synchron Player also includes a full fledged internal mixer with 5-band EQ, individual delay settings for runtime compensation, algorithmic reverb, phase switching, panorama controls as well as a host of effects such as saturation, delay, compressor, auto gain and many more.

The Vienna Synchron Player is included as free software with all Synchron Series products, the Vienna Smart Orchestra and Vienna Smart Spheres.

8-dimensional Synchron Player
The one and only sample player on the market with eight or even unlimited dimensions. Dimensions allow you to add any freely controllable musical parameter to any Synchron Series preset, resulting in incomparable versatility.

Streaming Performance
The look-up-function is up to 32 times faster than with conventional sample players. This improved look-up function is the backbone of the Synchron Player’s unrivaled multi-microphone performance. All samples are linked to their corresponding microphone positions which improves access-times dramatically and allows for minimal latency. Up to 31 microphone channels (Synchron FX Strings I) provide infinite options to create a unique sound.

Out of the Box
Tailor-made mixer presets – ready to play. Easy access to authentic room impressions of Synchron Stage Vienna – from close to distant microphone positions.

Inspiring Elements
The new Synchron Player offers an intuitive work-flow for epic masterpieces and delicate soundscapes. Simple navigation: Instrument presets with consistent structure throughout all instruments will boost your creativity.

Sonatina Orchestra Module

ZynAddSubFX free software-synthesizer by paulnasca 2

Sonatina Orchestra Module is a free rompler VST plugin developed by bigcat instruments. Compatible OS(s): Windows.

The Sonatina Orchestra Module puts the Orchestral samples by Mattias Westlund into a single VST Module for greater convenience. The whole ‘Rompler’ weighs in at a touch over 1 gig and since each instrument loads separately it should never take over 250 megs of memory (the choir is big). Most instruments use about 50 megs.

There are 20+ instruments including a soloist for every major instrument except the Viola and Double Bass. There are sections for all the important instruments including the Viola and Double Bass. Articulations include Pizzicato for the string sections and Staccato for the strings, brass and flute sections. There is also plenty of percussion along with a piano, harp and choir.

One Track Orchestra

One Track Orchestra free software-synthesizer by make some music now!

One Track Orchestra is a free software synthesizer developed by make some music now!. Available format(s): VST for Windows.

This is a simple and free VSTi plugin created to help you sketch/prototype your orchestral arrangements and productions in an easy and fast way.

This instrument puts a complete orchestra on a single track of your DAW (so you don’t need to create additional tracks). You can add strings, brass, woodwinds and even percussion at the same time, using only one MIDI channel.

The sounds of the different instruments are mapped on different sections of the keyboard, and they are velocity dependent. The only controls on the GUI are the reverb and volume faders.

This is a free sketching tool, created for songwriting/demo recording, and oriented towards beginners and songwriters who need a simple and fast tool, so it does not include multiple articulations or round robin samples. It is not supposed to be an alternative to big, professional sampled instruments and libraries.

The instrument is provided as-is, with no warranties. 32-bit and 64-bit versions are available. It should work fine on most DAWs. It has beed developed and tested on a Windows 10 PC and it worked fine with Reaper, Tracktion, Studio One, Podium, MuLab and SAVIHost.

This virtual instrument was designed by Luis Valoyes using samples from the VSCO Community Edition. The plugin is powered by Maize Sampler.

iChorder free chorder | studio-tool by JoBroMedia

iChorder is a free chorder and studio tools plugin developed by JoBroMedia. Compatible OS(s): Android.

So you spend days upon days in the studio, writing song after song. However the more you write the harder your brain has to bring out new ideas. Make no mistake, this will happen sooner or later. And when that happens, and you’re on a tight deadline, what do you do? Writing music like nothing happens might get the juices flowing a bit more, but what you need is more inspiration. Open your ears and eyes to other genres around the world. Think outside the box for a change.

iChorder is the tool to let you do this. It gives you 5 tools at your disposal to open your minds to new influences:

* Song ideas: This picks genres at random, giving you an idea on your next song, and it lets you search on youtube, soundcloud or google for the different genres so you can hear them out.

* 5th circle: This tool gives you access to an easily overview of the circle of 5ths. It showcases the prime and alternative scale, and also gives you the prime tone, subdominant and dominant for each scale.

* Timeline: This tool helps you create a visual list of your song. What part goes where. Length and other important stuff.

* Rhythms: This tool lets you generate a 4 bar long rhythm. It can be done randomly, and in a set of different complexities from simple to wild, and the rhythm can also be altered should the need ever arise.

iChorder’s task is not to write music for you, that is your own responsibility. This is just a tool to help you out with new ideas and inflictions on music. In short: iChorder is writer’s block’s worst enemy.
