Hi, I have had the HotSawz downloaded and updated for a few days but I can not get any sound from any of the 33 new algorithms. If I go to any other algo and select a tab, say CrushStation F5 Jumbo Shrimp or Mod Delay F8 PhaserEcho2.. everything works as normal. Not HotSawz though. But I can change the parameters etc (either via the app or with an experssion pedal) but still no sound whatsoever. Any suggestions would be greatly appreciated. I contacted support last Friday but haven't heard back yet.

Did you install the latest software onto your H9 via Pedal Settings->Update Stompbox's Software in H9 Control?  

You should be seeing "Software Version 5.6.0[0]" installed onto your H9 on the top right of H9 Control from the Pedal Settings page.
