## What is Shoom Synthesizer?

Shoom is an expressive XY pad synthesizer. Or, more precisely, three identical synthesizers in one app. It is capable of playing any pitch in the audible range and doesn’t necessarily limit you to a particular scale. Nevertheless, if you do want to use scales, Shoom can deliver anything from common 12-tone equal tempered to xenharmonic and microtonal.

Features:
• Three independent synthesizers
• 8–20,000 Hz pitch range
• Slide freely or snap notes to scale with adjustable glide rate
• Set notes to infinite hold using a dedicated toggle
• Microtonal and non-octave repeating scales support
• MIDI note input (including MPE), CC control and clock sync
• Optional remapping of MIDI notes to the pitches of the selected scale
• Bluetooth MIDI support
• Inter-App Audio support with main mix and individual synth outputs
• Audiobus 3 support (including AB MIDI)
• Ableton Link support
• 120+ bundled presets
• Import and export of presets and CC maps

Synthesizer engine features:
• Adjustable polyphony, up to 30 voices
• Two oscillators with 4 waveforms and PWM, and one noise generator
• Oscillator FM cross-modulation
• 4 pole (24 dB/octave) resonant low pass filter with overdrive and pitch tracking
• 2 variable slope ADSR envelopes for amplitude and filter cutoff
• 2 LFOs with 9 waveforms, up to 3 out of 12 simultaneously assignable parameters, trigger and global running modes, fade-in and phase controls
• Y-axis position / MIDI CC#74 as modulation source with up to 3 of 15 simultaneously assignable parameters
• MIDI channel pressure / polyphonic aftertouch as modulation source with up to 3 of 15 simultaneously assignable parameters
• MIDI velocity modulation of amplitude and filter envelopes
• Note pan randomizer
• Built-in stereo delay and reverb effects

### 4/5 — Great but…

*2025-01-14*

Fabulous…but needs AUV3 support…without that it….

### 5/5 — Один из лучших синтезаторов на iOS

*2024-08-14*

Очень жаль, что Юрий больше не обновляет свой замечательный инструмент. У меня есть бОльшая часть синтов на iPad, и Shoom один из самых любимых. Каждый раз как путешествие. Все еще очень надеюсь и жду мультиканальную AUv3 версию. В том числе, в виде встроенной покупки. Также встречаются баги, которые очень хотелось бы пофиксить. Но все равно меньше 5 звезд поставить не могу <3

### 5/5 — 2024 and still rocking

*2024-01-12, version 1.2.2*

This hits hard still. As someone that has a hard time understanding modular or affording, this is a great option. The sounds are fantastic!

### 5/5 — Awesome

*2023-08-23*

This app is awesome!!!  But to be honest I must say it took a little bit to get used to the layout and everything but once I got comfortable with it this thang is epic!!!

### 5/5 — Creative freedom

*2023-08-01, version 1.2.2*

This is the most versatile synthesiser I've ever seen. I'm having so much fun learning microtonal music and sound generation.

### 3/5 — Pretty cool

*2022-11-06, version 1.2.2*

Pretty cool app. Would be amazing if it was auv3.

### 5/5 — Amazing but missing AUV3

*2022-11-06*

This is a synth with unique features and sound but I wish it would support AUV3

### 5/5 — Remains one the coolest sounding synths for iPads

*2022-11-03, version 1.2.2*

Amazingly expressive, still essential in 2022.

### 5/5 — Lob an dem genialen Entwickler Yuri!

*2021-05-28*

Es gibt einfach keiene einzige schlechte App von diesem Genie Yuri Turov. shoom, xynthisizer und auch sein Effekt App. Als Musiker, kannst du wirklich alle seine Apps kaufen und du wirst nicht enttäuscht. Ich liebe seine Arbeit. Ganz besonders macht die App spass, wenn die ein ipad pro 12,9 hast. Unfassbar gut dieser Synth. Und obwohl ich ein Modular und Analog Nerd bin, überzeugen mich die oben gennanten Apps einfach. Diese App erinnert mich soooo krass an dem genialen Lyra 8 Synth, sowhl in Sound, als auch etwas in Bedinung. 🙏🏼

### 5/5 — incredible

*2020-10-25*

incredible. what i’ve always wanted in a synth. extra sick with my roli mpe!
