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
• 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

Problème qualité shoom à l'enregistrement

EDIT: il semblerai que lorsque l'on enregistre les sons de shoom sur audioshare, en passant ou non par audiobus (2 et 3), on perd en qualité...le son n'est plus aussi limpide.

application très interessante pour faire des drones, ambiances ou glitchs.

j'ai découvert grâce à la chaine youtube "thesoudtestroom" j'ai donc acheté et je ne suis pas déçu.

I haven't been able to reproduce the issue so far, so your help would be much appreciated.

Synth Nitouch ,


Ce synthé du développeur de xynthesizr vient juste de sortir donc le prix d'appel est intéressant profitez-en.Dans le même esprit qu'un Ondes , un Orphion ou un Poly mais en plus complexe et expérimental.On peut contrôler 3 synthés en live en pad XY avec moultes modulations.Les banques de sons et les presets sont de qualités.Ideal pour créer des drones,des pads ou même des arpèges,orientés musique électronique ou expérimentation musicale.Attention tout de même ça peut vite tourner à la cacophonie ou à un massacre de décibels si on étudie pas un minimum le manuel ou les vidéos de présentation.Un régal
