Sitala is a drum sampler for music creators that can add percussion sounds to Garage Band, Cubasis, AUM or any music software that supports Apple's AudioUnits. It can also be used on its own for finger-drumming or driven by a controller like a keyboard or drum pad. It has 16 slots that start off with our factory kits, but you can load your own sounds using our sample browser or drop in a drum loop and have Sitala slice it automatically. Sitala features: • 16 drum pads, each of which can play a user-assigned sample • Sample browser that lets you quickly swipe through all samples in a folder without importing each individual sample • 3 built-in drum kits: 808, retro and hip-hop • AudioUnit v3 plugin • Beat-slicer that automatically slices loops into individual drum sounds • Velocity sensitive, MIDI mappable pads • Special finger drumming mode with 4 giant pads for often used samples • Editable start and end points for each sample • A separate output for each pad (in multi-out mode) for hosts that support such (e.g. AUM and Cubasis) • Sitala for iOS can load kits created by Sitala for the desktop (macOS, Windows and Linux) and vice versa Six controls to sculpt each sample: • Shape: adjust the attack, length and sustain of your sounds while the overall volume remains constant • Compression: make your sounds punchier with more sustain Automatic gain makeup maintains the overall volume while chainging dynamics • Tuning: pitch sounds up or down by up to one octave while showing you exactly where the current sound falls in the frequency spectrum • Tone: emphasizes the highs or lows in a sound. Accentuate or scoop the midrange to position the sound in the mix. Adapts based on the pitch content of each sound • Volume • Pan

Verdict
