Apex Technology
The sound engine behind the current generation of Allen organs.
APEX II is Allen’s eighth generation of digital organ technology. It combines advanced processing with high-resolution recordings of pipe organs to reproduce their tonal character and musical detail. For organists, it offers an expressive instrument for worship, practice, and performance.
Why floating point matters
Older digital systems store sound in fixed point, which forces a trade between the loudest and the softest thing an instrument can reproduce. Soft stops lose their texture; the tail of a release gets truncated. APEX moves to floating-point processing, which Allen measures at sixty-five times the resolution of fixed-point systems.
You hear it in the places that matter to an organist rather than a spec sheet — a celeste that stays alive at pianissimo, a full-organ chord that does not compress, the decay of a chord in a live room rather than an abrupt stop.
Room for the whole library
APEX instruments carry roughly two hundred and fifty times the sound memory of previous Allen organs, driven by multiple 64-bit quad-core processors and premium 32-bit converters, with gigabit Ethernet moving audio inside the console. In practice that memory is what makes several complete, independently voiced stop lists possible on one instrument.
GENISYS Voices
Two dedicated voice stops per division, drawing on a library of more than two hundred and fifty additional sounds — further organ stops, orchestral instruments, grand piano, keyboard and percussion voices. Each one has its own volume and tuning, holds its assignment until the organist changes it, captures to pistons, and couples between divisions.
It is the feature most likely to matter to a small church: a modest two-manual instrument can cover repertoire and service music that would otherwise need a much larger stop list.
Working with existing pipework
An APEX console can be specified to play alongside ranks your church already owns. If you have pipes worth keeping — and many congregations do, even when the rest of the instrument has failed — that is the conversation to start with rather than the one to have after a decision is made.
