Based on the legendary Moog filter Arturia are offering a free filter plugin for a limited time. This is what they say about Arturia Minifilter;
The MiniFilter V software effect is the latest embodiment of work that started in 2003 when Arturia partnered with Bob Moog to recreate the illustrious synthesizers he designed as software instruments.
The 24dB/oct Ladder filter has always been at the core of the Model D mono synth myth. So we applied the greatest care and used the latest technological advances to reproduced its warm and highly musical tone.
But wait, there’s more. To add to the legendary filter we’ve developed new features to make it even more musical and to open up sonic discoveries. The sample & hold and sequencer makes the MiniFilter V a true sound designer’s tool for mixing, sound creation, and experimentation. All this is possible through one easy-to-use software plug-in that works in all DAW's.
The free offer is time-limited and requires an account (free) on the Arturia website.
