Cholakis has written an article in Sound on Sound (Nov. 2005 DVD 2) on the challenge of accurately recreating music dynamics with the current generation of samplers including Tascam's GigaSampler, Apple's Logic EXS24, Native Instruments Kontakt, Propellerheads Reason NN-XT and ReDrum, MOTU's Mach Five, Steinberg's Hallion and IK Multimedia's SampleTank.

"Hit Factors", written by Craig Anderton for Sound on Sound in 2002 explored Cholakis's research into the  links between a range of music and emotional responses; an analysis that exposed 
the hidden ingredients along with examples of what makes hit song's successful and how they appeal directly to our emotions.  

Has produced over 25 products for the contemporary musician, professional and serious amateur composer.

In 1992 Cholakis produced the first re-performance. A re-performance is taking an audio recording and precisely replicating what was originally recording by converting it back into an accurate midi file. The midi file of the performance can then be triggering back on a Yamaha Disclavier or a sampler. This process can be used to reproduce an important historical recording but in stereo or surround sound hi-fidelity or it can be used in a creative manner.

Cholakis created the world's first re-performance in 1992 (Aria of Glenn Gould's 1981 recording of the Gouldberg Variations). He worked with Canadian composer Christos Hatzis on his work the "Gouldberg Variations more information on this project can be found at the University of Toronto website . The Premiere performance (broadcasted nationally by CBC) was on September 26, 1992 by the Nouvel Ensemble Moderne under the direction of Lorraine Villancourt during the inauguration concerts of the CBC-Glenn Gould Studio in Toronto.

In 1999 Cholakis was commissioned by The National Ballet of Canada to recreate a re-performance on a Yamaha 7 foot Disklavier of the 1981 Glen Gould performance of the Aria from Bach’s Goldberg Variations the world premiere was in November 1999.

A very innovative company Zenph Studios has since released two re-performances (released on Sony Classical) - first is based on Glenn Gould's 1955 recording of the Goldberg Variations and the other is based on several important Art Tatum performances. More information at the Zenph Studios website.

As well, Cholakis has worked with composers developing original sound materials or "palettes". In 1996 Cholakis created original sound palettes for composer Christos Hatzis' composition "Footprints in New Snow" which won the International Prix Italia music award judged by the European Broadcasting Union (EBU).

As well as collaborating with avant garde composers and analyzing classical music, Cholakis has worked extensively with musician's original acoustic performances. Cholakis has co-produced the world's most recorded drummer Bernard Purdie, the world's most sampled drummer Clyde Stubblefield and top Reggae drummer Sly Dunbar.

Many of Cholakis' unique drone tones have been used in many feature films, film trailers and TV by many well known film composer and several Movie Studios such as Paramont Pictures, Warner Brothers and Lions Gate Entertainment have licensed material directly from Numerical Sound.

Numerical Sound has had loops, groove templates and reverberation impulses in such products as Digidesign's Pro Tools, Tascam's GigaPulse, Bias Inc. sound editor program Peak, and Cakewalk's Sonar, and Mark of the Unicorn's (MOTU) Digital Performer.
