hello! i need some help with my 2 beatstep pro

[Pomp]

hello!!! i have some issues with the sync on my two beatstep pro. i try to connect one bsp in INT and the other in MIDI, the clock its ok, but my volca sample and bass doesn't sound, i don´t know if a miss something. the secuences of my volca start but when i try to hit the pads sounds the others instruments connected on the other bsp.
for example: BSP 1 have the TR8s (channel 15), Minilogue (channel 14) and SH01a (channel 13) and sounds ok. (MIDI).
BSP 2 have volca bass (channel 12) and volca sample (channel 10) (INT).

when i connetc directly the second BSP MIDI OUT directly to the Volca   It responds correctly, it’s very strange. Can you help me? thanks

Hi Pomp,
Sorry, it is not clear for me which gear is connected to which one.
BSP does not perform MIDI thru. I guess there is a mismatch in your connections.
