"The Kärntnerland Alpsound (engineered by Limex) is a professional, compact MIDI sound expander built specifically for accordion and Steirische Harmonika players. This half-rack hardware module transforms MIDI data into authentic Oberkrainer and alpine folk music backing arrangements in real time.

Key Technical Specifications:

Form Factor: Portable 9.5-inch half-rack unit (1U height). Weighs ~1 kg.

Sound Board: 256 MB "Doppelpack" flash memory (combining Alpin Master and Tradition Exclusive libraries).

Polyphony: 116-voice polyphony to prevent note-clipping during complex live arrangements.

Audio Quality: 48 kHz high-fidelity sampling rate with integrated 24-bit reverb and chorus effects.

Connectivity: 5-pin MIDI Input, 12V DC power, and dual 1/4" (6.35mm) Left/Right stereo audio outputs.

Core Performance Features:

Dynamic Bellows Control: Seamlessly processes continuous MIDI CC data. The module alters the volume and tonal expression of instruments (like tuba and baritone horn) dynamically based on accordion bellows pressure.

Authentic Folk Instruments: Loaded with optimized samples of Styrian accordions, baritone brass, acoustic rhythm guitars, clarinets, and trumpets.

Plug-and-Play Live Setup: Connects directly between any accordion MIDI system (such as Limex MPR3/MPR4) and a live PA system or amplifier."
