1. my problem on the space is that the visual click, when the tempo is "on", doesn't behave like a steady tempo. a tempo is basically regular interval clicks and i suppose the visual leds do represent the tempo you choose in bpm. but on my space, "visual led clicks" are not regular intervals, it sometimes shifts and falls around the 1/8th then shift back.

2. is 5.2.0[6] the last version for space?

3 yes the issue is self-reproductible H9 Control always goes down this way.

1. Does your Space have this issue when you unplug all MIDI and USE devices and cables? Make sure your Space's MIDICLK IN setting is set to OFF.

2. Yes, 5.2.0[6] the latest version for Space.

3. Please take some screenshots and show us where the communication error happens. Please restore Space's system settings by powering up while simultaneously pressing the Right Footswitch and the Encoder until [CLEAR SETUP] is displayed, and try to connect to H9 Control again.
