Check if the MIDI is being split and sent to the 5 designated channels within the Kompakt player. You can do this by hitting the panic button in WordBuilder. Select the MIDI “panic” button. If you hear the choir at all, that means MIDI from WordBuilder is making its way to the SC Kompakt player, on at least one channel. MIDI is sent to WordBuilder on 1 channel from the sequencer, and it is processed into five parts by WordBuilder. WordBuilder then sends it out to the Kompakt player on five channels, and the Kompakt player separates the data into the designated multis. While sending MIDI data to the Kompakt player, (or using the panic button) through WordBuilder, solo each of the 5 channels in Kompakt. You should be receiving MIDI data on each of the channels in the Kompakt player.

If this doesn’t solve the issue, check once again the ranges of the presets in WordBuilder. Everything could appear to be sending and receiving MIDI data just fine, but if your MIDI notes are not in the correct range, you will not hear anything.
