## What is Oscidia?

Oscidia is an AUv3 plugin for iOS which can be loaded into your favorite DAW allowing you to use it as a sound source for any MIDI source. Its wide range of features and oscillator types allow it to produce a vast variety of sounds. In particular, the inclusion of WaveTable greatly expands the traditional wave types and brings a wealth of modulation options. Oscidia has 3 oscillators per voice, and each oscillator can be a different wavetable – all working and morphing together to create some incredibly amazing sounds.

Oscidia includes SINE, SAW, SQUARE, TRIANGLE, SUPERSAW, SUPERSQUARE, WAVETABLE and ADDITIVE wave types. You can import and export compatible wavetables using drag and drop directly to the WaveTable manager. Wavetables support morphing and warping (phase distortion), all controlled by the Mod Matrix routing. The SINE and TRIANGLE wave types both support several wave folding modes which allow dramatic real-time morphing too.

Oscidia also supports 5 filter types which support 12/24dB modes and morphable LP/BP/HP filter modes which can be automated from the Mod Matrix or via the Sequencer. The sequencer itself is very unique and allows up to 3 simultaneous ARPs to play at the same time. Each ARP can directly control the 3 oscillator levels independently per step, as well as the pitch, filter morph, cutoff frequency, probability, gate, note repeat and ties. This allows for some really complex rhythms to be created that are not tied to pitch. 

Oscidia Features:

• 3 Oscillators Per Voice.
• Support for Wavetable and Additive synthesis.
• WaveTable supports Morph and Warp (Phase Distortion) features.
• 4 LFOs Per Voice.
• 5 Filter types with 12/24-bit slopes and morphable LP/BP/HP.
• 4 ADSR (Attack, Decay, Sustain, Release ) or FEG (Fluid Envelope Generators).

• OSC Sync.
• XMod & Ring Mod (on osc1 & osc2).
• Additive Synthesis for glass, metallic and bell like tones.

• Mod Matrix.
• MPE Mode.
• Internal Effects - reverb, delay, chorus, Haas, and Phaser effects.
• Drag and Drop for import and export presets and wavetables.
• Build in Help Manual.

### 5/5 — Beautiful sound and excellent playability

*2026-05-31*

I think this might be my favourite synth at the moment due to the mpe and waveshaping and options of combinations...devs please take note of the mpe keyboard on this one and about two other devs apps that have similar use of touchscreen for mpe ...this is the most versatile playing surface ive tried yet, and itis close to perfect...THANK YOU DEVELOPER!

### 5/5 — Excellent

*2025-12-09*

Wow… Unexpected depth, with well designed ease of use and accessibility. Really appreciate the great sound and versatility of the oscillators and filters. The sequencer is really nice too. I’ve been collecting iOS synths for decades and have a lot of great ones… This is quickly becoming one of my favorites.

### 5/5 — More Power than than meets the eye.

*2025-11-27*

This app is full of great surprises, the presets are excellent sounding, they can be tweaked to create really great sounds, it has a fully functional wave table and synth engine, really glad I bought it 👍

### 5/5 — Great synth, but would love a random button

*2025-10-16*

Another great synth from 4 Pockets, and 5 stars for added Mac compatibility.

I would love to see a main settings randomiser option though (not just the one included for the sequencer), for generating new patches. It’s a great way to discover new sounds, something like the one on their previous synth release RingsFX, would do the job perfectly.

Hoping this will be added in a later update.

### 5/5 — Sounds GREAT

*2025-09-29*

Another winner from Paul [4 Pockets]

### 5/5 — Lush!

*2025-08-27*

4Pockets make some great apps but this is really special.  Sound is huge, rich, warm and analogue, sparkling and digital, and everywhere in between.  The interface keeps a big and complex synth manageable - even fun to use.  But it’s that sound!  Well worth modest price for the beast on offer.

### 3/5 — Does not work with the VoiceOver screen reader

*2025-08-27*

While some of the older 4pockets.com apps work great using voiceover, I would like to point out for any other blind and visually impaired users that may be considering purchasing this app that There is no way to Access any of the presets using the voiceover screen reader.

**Developer response:** Thanks for pointing this out as I wasn't aware of this issue. I'm thinking it is due to the fact I now use a Preset Manager to handle preset banks and that must not be compatible with the voiceovver.

### 5/5 — Well Designed Synth

*2025-08-26*

The synth works well with the tabbed windows. You can easily import wavetables into the synth using drag and drop from the files app. Includes a wide range of factory presets. It sounds great.

**Developer response:** Thanks for the great review, I'm happy you love it.

## Version history (last 5 releases)

### 1.08 — 2026-05-18

v1.08 B37
Now reacts to incoming MIDI all notes off CC123. This should avoid issues with Cubasis sticking notes.

### 1.07 — 2026-03-10

v1.07 B36
Fixed an issue where the cutoff frequency and morph within the sequencer were not always working as expected.

### 1.06 — 2026-01-12

v1.06 B35
Fixes a timing issue with the sequencer when Beat Align is enabled.

### 1.05 — 2025-11-29

v1.05 B34
Fixes another small UI issue on iOS26.1

### 1.04 — 2025-11-19

v1.04 B32
Fixed the references to FEG1 and FEG2 in the MOD MATRIX screen. This is a legacy bug that implies that ADSR1 and 2 can be used as FEG's which they can't.
So this change makes it clear that only FEG3 and 4 have the ability to change between ADSR and FEG.
Fixed an iOS26.1 rendering issue which was messing up corners of my popup menus and clipping popup contents (iOS26.1 issue only).
