FM Marimba Buzz (emulating a DX-7-type sound)
An attempt to program like a DX-7: 6 sine waves, 6 envelopes, several kinds of Frequency Modulation.
Unlike the original, but like any Moselle patch, you can go ahead and have any parameter react to any MIDI control, add filters and non-sine waveforms where-ever you want, add reverb or what have you.
Note the sound is recorded directly from Moselle: no hardware or external processing was used.
