V1.2

Thu, 05 Jun 2025 00:00:00 +0200

Synchronization & Network Latency Compensation:

SYNCED input: ensure all connected participants hear a backing track or click simultaneously (no latency), regardless of the distance.
Synchronized transport: synchronize all connected applications, with built-in clock latency compensation for latency-less realtime playback.
Synchronized recording: start/stop recording in sync with playback accross multiple devices on the network, and keep all recorded files synchronized.
Optional realtime network latency compensation: Fader Hub can compensate the network latency on all LLAN mixer strips for a perfectly synchronized mix.
Automatic network latency compensation for recording: latency is automatically compensated for perfect synchronization of individual recorded tracks.
Reported latency is now displayed in the status bar (bottom right).
Check reception latency for each LLAN Mixer channel by hovering the mouse on the drift meter (ppm).
Synchronize app transport & bpm with other devices/software with MIDI Clock and/or MIDI Timecode (MTC). Both send and receive supported.

Performance:

Improved connection stability when sender under high CPU load.
Optimized performance: Up to 50% lighter on CPU when not using all available channel strips.
