Waveforms (Sample Tracks) not played with MIDI

[cavimaster]

Hi everyone,

I have a doubt. I don't know if it's me but when I assign, for exemple, the MIDI channel 7 for the symple track N ° 7 (by correctly setting the track and MIDI assignments), it plays the samples well but as soon as I put one from waveforms it don't play notes.
I forgot something or is this normal behavior?

Thank you!
