This video provides a fast overview showing the most important features.

Its a bit long, so use the content table to quickly jump to the chapter you want to see

Main Features:

Realtime Control

There are many ways to control the many functions of CH-Ensemble Strings.

The minimum requirement is a MIDI - keyboard and a computer. You can draw all MIDI CC data in your DAW.

However, a set of hardware faders and pedals helps to achieve a good realtime performance.

Beside that, there are a bunch of cool controllers to make a realtime performance fun.


Based on Hexlers TouchOSC,

I programmed a Real Time Controller for iPad.

Its not just fun to edit each and every function in

CH-Ensemble Strings from your iPad, the biggest benefit is, you can easily record the edits directly into your DAW.

Instead of fiddling with midi CCs in your sequencer, just press record and move the knobs and faders on your iPad/iPhone to record the controller movements with your sequence.

Just get TouchOSC for a cheap prize at the Apple App Store, and install the Real Time Controller which is included in the downloads.

Leap Motion & GECO Midi

The Leap Motion is an inexpensive sensor, which can be used in combination with the GECO midi app

to control multiple MIDI CCs at once with intuitive gestures of the left hand while playing the notes with the right hand.

Here you see me controlling CH-Orchestral Brass with the

Leap Motion. It works the same way with CH-Solo Violin

with the Leap Motion and GECO Midi

Watch Berthold Matschat in a realtime performance with CH-Solo Violin using various

hardware MIDI Controllers.

The same performance is possible with CH-Ensemble Strings

Berthold controls six functions in realtime:

  1. -Articulation presets changes via Keyswitches

  2. -X-Fade via Yamaha BC1 Breath controller

  3. -Note Heads via Expression foot pedal

  4. -Volume

  5. -Artificial Vibrato on/off

  6. -Portamento Legato via sustain pedal

The ensemble instruments have been mixed from a raw sample pool of over 120,000 samples – but not using ensemble recordings, but from perfectly tuned and edited performances of solo players.

Unlike when recording a group of players simultaneously, we had perfect control over tuning, timing and character of each individual player in the ensemble.

These ensemble instruments are completely free of any players performance errors that plague many ensemble string libraries.

The samples have been carefully detuned, time shifted, positioned in the stereo field and mixed down to a 24 bit stereo mix.

This surgically detailed production process has resulted in a warm and rich symphonic string sound.  Two different section sizes have been created: „Full“ and „Small“ ensemble.

Also this method of mixing an ensemble from single solo instruments has allowed us to tailor a huge range of articulations which actually haven’t been recorded.

For example, the Pizzicato and Col Legno articulations are available in two versions: “Loose” and “Tight”, which have been achieved by shifting the timing of each individual samples in the ensemble.

Some cool mixing tricks provide unusual but useful articulations like:

Cluster  Clouds, Octaves, Repetitions and Runs.

There’s also a complete construction set of designed Sound FX.

Thanks to the unique production technique, the vast array of 32 articulations with up to eight dynamics and the many controls, Chris Hein Ensemble Strings is a very flexible tool to fit any musical style.

This demo was played live, straight out of the box using only a single articulation and CC11 for dynamic X-Fade.

No keyswitches or any other controller were used.

Watch Thomas T. Weber

playing Bach‘s prelude BWV 867

with CH-Ensemble Strings.

He uses only one articulation:

„Dynamic Expression long“

No additional function or controller was used.

No editing, ne external effects.
