Hi, I've created a drum beat in Samplitude Music Maker using the Vita Rock Drums instrument using the MIDI editor. Now, I'd like to change the reverb over one bar. In the controller slot 3, I've selected 91: Reverb, and I use the Free Hand drawing tool to draw a reverb pattern. When I play the track, I however do not hear any difference in reverb over the bar where I wanted the reverb to increase. How would I go about implementing such reverb? Is there any tutorial / documentation on this (all the documentation / tutorials I've seen only cover the basic functionality...)
