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)
