About

The Phil

Features
Read full description

Fancy a synth that actually feels like a "traditional" instrument, but still able to push things a little weirder? The Phil is a fast, expressive AUv3 plucked string synth that brings proper physical modelling to your DAW, no faffing about required. Poke it, pluck it, let it ring out, and it responds like a real string, all wrapped up in a neat little AUv3 plugin for your DAW. Tucked inside is a built in arpeggiator, designed to create "human" feeling patterns without touching a step sequencer. Add in a solid handful of controls over decay, brightness and damping, themselves with "humanize" controls to mimic how a real hand would move on a string and you can go from delicate acoustic plucks to properly synthetic, metallic textures in no time at all whilst also having the option to turn down the robot vibe if you like. What you get: Physical modelling synthesis for genuinely plucky, stringy tones Built in arpeggiator for patterns that keep things moving Real time controls to shape decay, brightness and character Full AUv3 support, slots straight into your host Light on CPU, so it won't grind your session to a halt Plays nicely with AUM, Logic Pro, Loopy Pro, Cubasis and GarageBand Whether you're building layers in the studio or winging it live, The Phil is the sort of instrument that surprises you a little every time you touch it. In a good way. Search for decibelboy83 on YouTube for a walkthrough video. Works with: AUM, Logic Pro, Loopy Pro, Cubasis, GarageBand, and any AUv3-friendly host.
