NexSyn, designed by Koblo Co-Founder Max Gronlund, is a powerful Hybrid Synthesizer with a huge range of loadable oscillator types to meet the sound demands of modern musicians and composers. NexSyn is capable of loading sample-based keymap files, in the proprietary XWM (Extended Wave Memory) format. It features a powerful and feature-rich synthesizer engine, and is the only one of its kind to offer NetNotes, an online preset browsing and sharing service which allows users to find new sounds for NexSyn in seconds via the Internet. NexSyn also features a true stereo signal path, which gives NexSyn a "lifelike sound", and an ultra-tweakable interface which will appeal to sound designers of all kinds.

NexSyn's XWM sound-sets are provided by Big Fish Audio. NexSyn comes packaged with 130 megabytes of XWM synthesizer-based sounds, which can be loaded into two of NexSyn's three Oscillators. More XWM soundpacks will be offered via Koblo.com, with sounds ranging from Pianos to Orchestral and Percussive sounds, and more. These XWM sound-packs will be offered at extremely low prices, allowing users the chance to easily expand their synthesizer's sounds.
