For "man of la mancha" i needed the sound of don quixote hitting the stage while off stage fighting windmills. I dropped a sandbag a few times, and added the sounds together. You can hear the slight reverb from our walls. I wanted the slight echo effect of the stage, so that the audience thought he really fell.
Created using tracktion waveform-10. I used 3 instances of the builtin synth subtractive, 1 was for the body of the snare the other 2 were the noise to try and replicate the wires of the snare, finally i used zynaddsubfx to create the transient. There was some eq applied to boost key frequencies in around 200hz and mastermix plugin to compress the audio.
