I recently purchase the HTD Lync 12 and HTDNET-Lync to use in a 12 zone whole house audio solution with my two 12 channels amps. Is anyone using the HTDNET-Lync controller? I love everything about this setup except the volume control using a smartphone or tablet. Instead of having a slider for volume control it has a drop down menu with radio buttons from 0-60. Adjusting volume this way is much clumsier than a slider but the bigger issue is when you want to go from low volume to high volume. If you change from 5 to 40 the volume doesn't ramp up slowly/smoothly, it jumps instantaneously to the high volume (scaring everyone including me). Has anyone experienced this? Is it an issue for anyone else?
