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.

• Three independent synthesizers
• 20–20,000 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 CC control and clock sync (MIDI note input coming in a later update)
• Inter-App Audio, Audiobus 2 support
• 60+ 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 as modulation source with up to 3 of 15 simultaneously assignable parameters
• Note pan randomizer
• Built-in stereo delay and reverb effects

iOS Synth Nibbana

Whilst it's great to have so many iOS simulations of vintage synths, it's also interesting to use iOS-specific instruments. This is really 3 synths in 1 and it goes super-deep (if you want to); perfect for experimental ambient drone soundscape whatever stuff, and you don't need to be a synth boffin to get quick results. Obviously people would like midi note options but in a way it's nice to be non-sequenced and enjoy a bit of freeform space. Nice one!


Not bad, but lacking in features

Nice synth sounds, and good UI. Bit basic though and lacking in features. An arpeggiator or MIDI in would be handy, for example, making it more useful for lead and bass sequenced stuff as its a bit drone based at the moment.

Not much updating happening, but hopefully the Dev has some new features in the pipeline.

A good app, but not using it as much as I thought I would.


Luv this...

...for creativity it's very good. It's not a 5* app (I don't care what people say about it...they're wrong). The learning curve is more like a straight line so if you want to get your teeth into something then go for something else. If you want great results for little work then go for it. 5* my arsenal.
