Dolby Atmos is very similar to DTS:X, but the technology itself is quite different. Both Atmos and DTS:X are object-based surround sound technologies, but Atmos puts more emphasis on height – so much so that Dolby recommends you install ceiling speakers to get the full benefit.
A 5.1 system (made up of five satellites and one subwoofer) with four Dolby Atmos speakers would be referred to as 5.1.4. 7.1.4 is the reference set-up for Dolby Atmos – in other words, the tech runs natively on a set-up comprising seven satellites, one sub and four Atmos speakers.
DTS:X has the edge in terms of sound quality because it supports higher bit rates - Dolby Atmos codecs are more efficient than DTS-X hence sound comparable or even better at a lower bit rate

Released by Edirol (a subsidiary of Roland Corporation), the Hyper Canvas was a software implementation of Roland’s legendary hardware sound modules, namely the SC-88 Pro and SC-8820. Unlike many modern synths that focus on analog warmth or wavetable mangling, Hyper Canvas was designed for one specific purpose: flawless General MIDI 2 (GM2) and Roland GS format playback.
The VST acted as a 32-part multi-timbral synth, meaning it could play up to 32 different instruments simultaneously on separate MIDI channels. It came packed with over 1,100 patches, 30 drum kits, and a suite of digital effects (reverb, chorus, and delay).
For musicians who still trade MIDI files (The .mid format), Hyper Canvas is the definitive playback solution. Unlike Microsoft’s built-in GS Wavetable Synth (which sounds thin and cheap), the Edirol VST restores dynamics, velocity layers, and correct volume balancing. It makes a poorly sequenced MIDI file sound like a professional backing track.
If you grew up playing PC games from 1998–2005, you’ve heard HyperCanvas. Many game developers used it for background music because it was lightweight and reliable. That slightly bright, clean, almost “plastic” piano sound? That’s pure HyperCanvas.
Here is the tricky part. Edirol was discontinued by Roland around 2013. You cannot go to the Roland website and buy HyperCanvas today. It is considered "abandonware" in many circles.

Disclaimer: I do not endorse piracy, but it is worth noting that because the product is no longer sold, many musicians hold onto their old installer files religiously.
