ArrangerX Smart Calibration 0.1.0 - FREE reference diagnostic

Windows 10/11 x64. Extract this entire ZIP, then double-click SmartCalibration.exe. Keep _internal next to the EXE. No Python or ArrangerX installation is needed.

The test uses the same ArrangerX synthesis/sequencer engine, 44.1 kHz, eight parts, reverb and chorus, and an ORIGINAL 512 MiB four-layer reference SF2. It checks 32 MIDI notes, higher note counts, and buffer headroom. SoundFont sample voices differ from MIDI notes. Highest passed count is measured test capacity, not a universal maximum.
The X1 may use Windows sample-rate conversion where the output native rate differs. No acoustic latency/dropout measurement is claimed. Requested buffer size may differ from actual WASAPI callbacks. Background load, other SoundFonts and styles can change performance.
This is an early diagnostic preview. No installer/admin rights; delete its folder to remove it. Windows may display its normal unsigned-app notice.
