Slendronica#1 is my 3rd piece in Slendro using my fractal AC tool. Besides refinement and expansion of the algorithmic composition code, these pieces have served the purpose of trying to find FM timbres that work with 5-TET. If successful, it is highly likely that similar or related designs would be effective in most or all other equal temperament tunings.
This song introduces a ModFM synth for the swelling pad sounds, based on the design presented by Victor Lazzarini in his article "Distortion Synthesis" in Csound Journal issue 11. It also uses 7pm, my seven oscillator PM synth (for the belldrum).
