Alpha Organ Black Friday pricing takes 50% off this Soundiron Kontakt library of two pipe organs, so it comes to $49.50 until Dec 6, 2026.
The library was recorded at St. Paul's Church in San Francisco. Both organs were captured on their own and played together in unison, using several microphone types and positions.
The "lower" instrument, the Alpha organ, was built by Kilgen Church Organ Company of Saint Louis. It started out water-powered and now runs on an electric blower. Soundiron describes its tone as sweet and silky.
The upper instrument, the Omega organ, comes from the Felix F. Shoenstein & Sons Organ company of San Francisco. It sits in a mezzanine between the two bell towers, with a bigger console, a stronger blower and many more pipes. Soundiron calls it thunderous and mighty.
The Kilgen's blower and machinery sit under the floor of the Apse. The maker says that lets the lowest pedal notes rattle through the floor.
The hall itself is described as lush and spacious, with clear highs and no cloudiness. Soundiron says the same room is where it recorded its Requiem Light Symphonic Choir and the Native Instruments Symphony Series Brass collections.
Each preset lets you shape how the volume builds, set how quickly notes begin and fade, adjust where playback starts within the sample, add vibrato, and pick which bank of sounds it draws from. The main preset adds a microphone mixer and an octave effect.
The Layered preset stacks 4 independent layers. Layers one to three are the Close, Mid and Far mics, and the fourth is the Ambiences layer. Each layer has its own full parameter set, and the parameters can be linked or automated.
The advanced settings window holds a per-layer LFO with selectable shape, target, speed, intensity, tempo sync and fade-in. You also get 13 filters, with modulation sources including velocity, mod wheel, expression, aftertouch, key position and a step-sequencer table.
The arpeggiator has a velocity sequencer table, plus direction, note timing, swing, randomization and duration controls.
Its modular effects rack lets you arrange up to 8 of 27 DSP modules in whatever sequence you like, covering things like phasers, flangers, echoes, overdrive, amp and speaker cabinet models, dynamics processors, equalizers, rotary speaker emulation and further options. The reverb section carries 99 convolution impulse presets of rooms, halls, chambers and outdoor spaces, plus 139 special effect impulses.
Alpha Organ runs in the free Kontakt Player (version 6.2.2 or later) or in full Kontakt (version 6.1 or later), as a VST, AU or AAX instrument. It adds to the Kontakt Libraries browser and needs online serial registration through Native Access. It also works with Komplete Kontrol and NKS hardware and software.
Windows 7 or higher or macOS 10.12 or higher is required. Soundiron recommends a dual-core CPU, 3 GB of RAM and a SATA or SSD drive. It arrives as a digital download, so you need a broadband connection.
