I’ve got a MIDI chain that runs as follows: Hotone Ampero Control (with a Roland EV-5 expression pedal connected to it) → BeatBuddy (channel 1) → Aeros Loop Studio (channel 1) → Hologram Chroma Console (channel 2) → Hologram Microcosm (channel 3)
The Amerpo/Roland are set up so that if I move the expression pedal, it sends higher or lower values for a certain CC on one of the Hologram pedals’ respective channels. This works as expected, so the messages are being passed through the BeatBuddy and Loop Studio. However, whenever I press down or up on the expression pedal, the Loop Studio also acts as if its BPM is being changed, as follows:
-
If the BPM hasn’t been set in a recorded loop yet and the Loop Studio is in the loop setup screen, the BPM will dip down 1-5 beats for a few moments and then go back up to the BPM that has been set by the BeatBuddy.
-
If the BPM has been set and I go back to the loop setup screen and press the expression pedal, the BPM will turn red for a few moments, indicating the BPM is trying to be changed but cannot be changed (since it’s already set).
-
If the loop is playing and the BPM has already been set, the loop studio loop will start getting slightly delayed, and some weird clipping or gaps start to happen between the beginning and end of the loop.
At no time during any of the above does the BPM value shown on the BeatBuddy change. The Hotone/Roland are sending the messages to a channel that the Loop Station isn’t even supposed to be listening to, for CCs that I don’t think are even relevant to BPM at all (e.g., CC 9 — although the CC doesn’t seem to matter — I’ve tried various ones). I also tried filtering out CC messages on the Loop Station entirely, and this doesn’t do anything either.
Any ideas what could be going on or what a possible fix could be?
