About

Spectra is a virtual instrument player for iPhone and iPad, built for instruments in the SFZ format. It turns your iPad or iPhone into a powerful rack with up to 32 simultaneous sounds, controlled by a MIDI keyboard, with a mixer, per-channel effects, and global reverb. Designed for live performance, studio recording, and rehearsals. Connect a MIDI keyboard — using a Camera Connection Kit, USB-C, Bluetooth MIDI, or a USB MIDI interface. The app detects it automatically. Open Spectra. Play! Features: Play with up to 32 simultaneous channels, creating layers, splits, and instrument combinations for different musical situations. Save and load setlists/presets with all instruments, volumes, effects, MIDI mappings, and setup configurations. Load SFZ instruments directly from the Files app, iCloud Drive, or AirDrop. Control the app with a MIDI keyboard via USB-C, Camera Connection Kit, USB MIDI interface, or Bluetooth MIDI. Use a complete mixer with individual volume, mute, real-time audio meters, and reverb send control. Shape each sound with editing tools such as pan, velocity curve, MIDI channel, MIDI Learn, EQ, filters, tone modifier, and compressor. Create setups with specific MIDI channels or OMNI mode, ideal for using multiple keyboards, zones, splits, and live performances. Global Reverb. Enable Prevent Screen Sleep mode to keep the screen on during performances. Adjust the audio buffer to balance latency and performance according to your device. Use the Panic button to immediately stop stuck notes during a performance. Spectra was built for musicians who need a practical, portable, and reliable setup to play with high-quality sound anywhere.

What's New in Spectra

2.0

August 12, 2026

The All-New "Spectra" Interface Futuristic Glassmorphic Design: Say goodbye to the old look! Enjoy a modern, sleek dark theme with glowing borders and translucent glass panels. Volume Faders with Integrated VU Meters: Volume controls now pulse and glow in real-time according to your audio level, with distinct colors matching each instrument category. Minimalist Rotary Knobs: Effect knobs have been refined to display values cleanly via a glowing neon arc. "Add Instrument" Button: A new vertical pill-shaped button that keeps the mixer screen clean and organized. Seamless External File Loading Import from External Folders (Downloads): You can now load sound timbres directly from external directories on your iPad/iPhone (such as the Downloads folder). For instruments with multiple audio samples, simply select the entire folder, and Spectra will load everything automatically! Smart Preset Recall: When saving your custom setups, Spectra now remembers the exact location of your external files and restores them automatically upon loading. Audio Optimizations & Balanced Volume Automatic Volume Normalization: No more quiet instruments or sudden volume spikes! Spectra now analyzes and auto-balances loaded SFZ instruments to play at their maximum definition without clipping. Stay in Tune: Fixed an issue where the sound pitch would drift (sounding too high or low) when plugging/unplugging headphones or connecting Bluetooth speakers. Support for Third-Party Plugins (AUv3) Host External Instruments: Load your favorite virtual synths and third-party instruments installed on your Apple device directly into the Spectra mixer. Native Plugin Editing: Open the native user interface of your installed plugins in a popup window to tweak parameters freely.
