Free FM synth for Win/Mac on GitHub.

-Four operators with independent parameters such as volume, panning, modulation index, feedback, three different frequency modifiers (ratio, free and fine) and ADSR volume envelope parameters. The operators can be independently switched to white noise mode

-Flexible routing allowing setting the output operator (with some limitations) as well as the percentage of signal that is simply added to the final output, enabling additive synthesis. By default, operator 4 is routed to operator 3, operator 3 to operator 2 and operator 2 to operator 1.

-Master volume and master frequency parameters

-Four LFOs capable of targeting most operator parameters as well as most parameters of lower index LFOs.

-128 voices (using them all simultaneously might consume quite a bit of CPU time though)

-Fully automatable

Tube Preamp

This tube preamp emulation has been developed Philipp Bulling as a thesis work. Philipp has been offering the plugin in VST format for some time on his own website. He has now moved on to new areas for some time already but didn’t want to let down his users. Hence, DDMF took over the code and will continue to offer the plugin as freeware, with the intent to further improve it and maybe add some more bells and whistles in the future. Download here.
