Oh man…This thing rocks so hard! Don´t know if I ever had so much fun with a piece of synth gear from the very first moment. 
My wife got me the West Pest for christmas. 
Unfortunately it took me some time to even get started. Both the 1/8 to 1/4 jack cables I had were broken + the midi issues (as others have described) made it very hard to figure out what was happening. Lol.
The note hangers were a dead give away it was a midi issue, but it just spitted out crackling noises…The crackling noises seem part related to my broken cables and part to incoming notes, as incoming notes considerably made the problem worse. My hard sank…That wasn´t the type of noise I had in mind damn! Anyways, took me an hour to figure it out.
My AK can play it fine from the keyboard (haven´t tested AK midi seq, yet), the OT makes it freak out. It plays fine over midi from my DAW, tho.
I arrived at using the inbuilt sequencer, sending clock from OT works fine. This way I can use the inbuilt sequencer in sync with my other gear, it responds to start/stop, as well, and I can make use of the tempo sync lfo (multi tool modulation).
Btw, note hangers can be cleared with Yellow Button+Keyboard D (Hold). Engage hold and then press the button combo again to release note hangers.
Anyone knows how I can check the firmware? I guess there´s no button combo are smt like this? Have to plug into the pc over usb and use their little updater app?
Not sure if I would update if mine was an older version, though. It works fine (with limitations descrived above), don´t want to make it worse…
Btw, hi ya´ll.
