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

Verdict

The call

The clearest difference is update cadence: sinusedo at weekly against Shoom Synthesizer's every 13 months. sinusedo also leads on price ($3.99 vs $6.99) and review sentiment (100% vs 87%). Shoom Synthesizer's advantage is ratings volume (64 vs 7) and iOS requirement (9.0 vs 15.0). On rating, ads, in-app purchases and monetization model there is nothing between them.
