Flexur and Chill, with this Trautonium-inspired DIY synthesizer

I missed this when it dropped earlier this month — Synthtopia was there! But now is a perfect time to chill out to the smoothly gliding sounds of this original Trautonium-inspired synthesizer design in progress. Flexur can cool down an overheated Europe.

Sequential Prophet-5 gets an official software remake by GForce — tested

Following GForce’s official renditions of Oberheim instruments, now we’re treated to an official Sequential synth in plug-in form. This Prophet-5 combines painstaking recreations of the various revisions with new features like MPE, a dual-layer architecture, and lush effects. I’ve been testing it and got some behind-the-scenes details from the devs. It’s such a total pleasure to bring that Sequential sound into the box.
