Today I’m happy to introduce NPD — a phase distortion synth for iPad. It has a clean and streamlined interface that is simple to use. The synth works as an Audio Unit extension (AUv3) inside host applications such as AUM, Auria Pro, Cubasis, GarageBand and NanoStudio.

Key features

• 3 oscillators with shape and harmonic controls
• Noise oscillator
• 2 filters with routing options
• 3 envelopes with adjustable level, time and curve parameters
• 2 flexible stereo LFOs
• Fully featured modulation matrix
• All signal paths are stereo. This allows complex stereo modulations
• Build-in effects: distortion, phaser, chorus, delay
• Voice modes: monophonic, polyphonic, legato, glide
• Preset management inside the app
• Numeric pad for entering parameter values precisely

I’ve been working on NPD since September 2017 and I’m very happy to see it complete. This year I’m planning to work on an entire album on iPad and I know I’ll be making heavy use of this synth.

I would like to thank all the beta testers for their valuable feedback and the artists who have sent their presets to be included in v1.0. If you have further feedback don’t hesitate to get in touch.

Grab the app from the App Store.

A quick note on my other AUv3 apps. I’m currently working on bringing some of the UI, DSP and some internal improvements made in NPD over to NFM, and then later on to NS1. Updating NS1 may take a bit longer due to the fact that it’s written in Swift 2.3 and Xcode migration can’t seem to be able to handle migrating the code to the modern syntax very well. But more importantly, NS1 is fully optimised for accessibility. I’m hesitant to break that feature. Having said that, NS1 is a very important app to me, so it will get a proper update at some point.
