I have a TR-808 and a TR-909 connected to my Hapax via MIDI, separate outputs on the Hapax and separate MIDI channels. If I play the drums in live mode, I can happily trigger multiple sounds at once. If I enter step mode however, only two sounds seem to be playable at once, with the third step simply ignored / not played.
I can’t find any config in the Hapax that would relate to polyphony and have also ruled out other issues such as:
- Both drum machines can sound three notes at once using their internal sequencers
- Likewise with MIDI from Logic
- No issues in live mode
Does anyone have any ideas or has anyone experienced this?
