Give your action, sci-fi, and horror scores a blockbuster boost with the fourth volume in ProjectSAM’s acclaimed Symphobia Series. Pandora lets you summon rousing cinematic risers, foreboding falls, and earth-shattering crescendos with unmatched ease and flexibility. Pandora’s innovative Adaptive Sync quickly and effortlessly matches its huge library of articulations and effects with your sequence – so your next deadline needn’t be a nightmare. Plus, fully-customizable sound design tools help you quickly sculpt your desired timbres.

  • Effortlessly sync risers, rolls & crescendos to your sequence with Adaptive Sync
  • Over 140 GB of orchestral ensemble recordings covering strings, brass, woodwinds & percussion
  • Generate thrilling scores with powerful, fully customizable sound design tools
  • Complete articulations in 5 mics




Pre-recorded crescendos and rolls sound great. But they used to have a disadvantage: they were not very flexible. Any composer will recognize the trial-and-error process of nudging a crescendo note around until it ends in the right spot. It’s a tedious task that most of us would rather skip if we could.

This is why we developed Adaptive Sync.

Symphobia 4: Pandora is packed with transitional samples – sounds that progress dynamically or directionally over time – ranging from powerful brass crescendos to dissonant string risers. These samples all have one thing in common: a distinct, musical ending or climax.

Feature Preview: Adaptive Sync

With Adaptive Sync, you can simply set the number of beats or seconds you need the crescendo, roll or riser to be. Tapping from a vast pool, Adaptive Sync automatically picks the best matching recording from its database and intelligently adjusts it to match your hit point exactly. Similarly, you can very quickly time a crescendo or roll with the next downbeat*. If you move a note backwards or forward, the engine will automatically switch to a better matching recording if needed. If you change your track’s tempo, Adaptive Sync will adjust accordingly.


Symphobia 4: Pandora offers a vast selection of big & bold, playable ensemble articulations, ranging from cellos and basses to a massive 30-player low-range Tutti Orchestra. For all crescendos and swells in there, Adaptive Sync is ready to assist.

The articulations have all been selected and recorded to add unprecedented oomph to your existing orchestral template. Symphobia 4: Pandora is the ultimate cinematic finishing touch.

A selection of the instruments offers exciting, optional sound layers that can be mixed in with the main articulation on-the-fly. For example, the Tutti Orchestra crescendo instrument displays controls for quickly adding gran cassa, timpani and cymbal rolls. Similarly, you can quickly add a sub sweetener to the bass drum and tutti percussion instruments.

The Symphobia Series has always been the go-to place for orchestral effects. For Pandora, many a bone was chilled during the effects sessions. The library packs more orchestrated effects than ever, ranging from eerie violin textures to loud brass stabs. And with Adaptive Sync and Sound Design Mode, the recorded effects are now more flexible and customizable than ever. For thriller, horror and sci-fi scoring, Symphobia 4: Pandora is an absolute must-have.

Pandora’s dedicated Effects Module in combination with its Sound Design Mode gives you the power to turn any orchestral sound completely upside down, creating dark soundscapes and ominous textures utilizing the synchronized stutter, pitch envelope and other tailored effects.


Clicking the triangle icon activates Sound Design Mode. This allows you to directly manipulate a selection of the mapped samples and highly customize your preset using the waveform control. You can jump-start sample positions, reverse playback, reverse sync to downbeat, time-stretch and more. These features are available even for instruments that use disk streaming by default. We keep building on the foundation of Sound Design Mode in future library updates.

Clicking the triangle icon again instantly takes you back to the safety of Orchestral Mode.


Symphobia 4: Pandora features both Cluster Pulses and Tonal Pulses.

Cluster Pulses are idiomatic note combinations that add instant cinematic drive to your track. Each key holds a different recorded cluster of notes for the strings, brass and woodwind sections. For each pulse, a matching crescendo and staccato crescendo phrase is available. These work great as intros and outros, particularly when combined with Pandora’s Adaptive Sync crescendos and rolls. Tonal Pulses are available for low and mid strings, performed in octaves and in unison, respectively. The Tonal Pulses offer additional, synchronized synth layers that can be mixed in with the orchestral pulse on-the-fly.

All pulses have been recorded in 4ths, 8ths and 16ths repetitions. The Pandora interface allows you to switch mid-pattern, with synchronization completely intact.

Feature Preview: Cluster Pulses


No cinematic library is complete without a solid collection of tension-building string risers. For Pandora, multiple recording sessions were dedicated solely to this, covering lengths from 2 to 15 seconds in different playing techniques and dynamic arcs, including arco, accelerating staccatos, harmonics and sul ponticello tremolo. Here too, matching up the risers with your sequence is a breeze thanks to Adaptive Sync.

You can use the orchestral risers in their original form, or give them the trailer treatment by adding an idiomatic, accelerating stutter effect and some saturation using Pandora’s Effects Module. A number of Snapshots are included as inspiring examples. Pandora also includes a set of suspenseful string downers.

Feature Preview: Risers


Mind your volume!

Combining the library’s individual articulations, effects, pulses and percussion, Pandora’s Combos hold some of the biggest orchestral ensembles you’ve heard yet. All elements inside a Combo are able to directly communicate with one another, allowing for musical wizardry such as the on-the-fly aligning of a col legno hit to a brass crescendo’s climax. Or a big tutti diminuendo at the end of a riser.

Combos featuring multiple Adaptive Sync instruments allow you to set the length and timing of the entire ensemble with a single set of controls.

Feature Preview: Combos


Symphobia 4: Pandora fully supports the Native Kontrol Standard (NKS), offering Light Guide, Native Database and direct control of almost all of the Pandora’s on-screen parameters from Native Instrument’s awesome Komplete Kontrol keyboard series.

* Downbeat synchronization is currently based on the time signature at the moment of the incoming note. This is because of technical limitations in the communication with the host software. If your track has multiple time signatures, we recommend using Sync in Beats mode instead. As soon as it is technically possible, we will add deeper downbeat synchronization via an update.

Versatile, grandiose and packing a massive attack, this intensively sampled orchestra gives no quarter.

- Sound on Sound (June 2020)

By tweaking sound-design parameters and adding multiple effects, I could get a lot more musical mileage from Pandora than you might think initially. Instant Sonic Mayhem.

- John Krogh, Synth and Software

Incredible selection of sounds for action, blockbuster and horror scoring. Adaptive Sync saves tons of time. A one-stop toolbox for modern scoring and composition.

- Ask.Audio

The 5-Star sonics catapult Symphobia 4: Pandora into a league of its own. Don’t dismiss this library as “just aleatoric,” as Pandora packs sync controls, pulses, and sound design options that allow users to compose complete cues with this toolkit alone.

- Sample Library Review

The timing functions are incredibly easy to use and very effective, offering a significant strength, being a huge boon to workflow.
