4 Royalty-Free Audio Tracks for "Triangle Fm"

Using a home built fm synth with sequencer. Two triangle waveforms, two voices. Changing some parameters during the sampling.

Basic sequence of one fm voice with a noise waveform and one fm voice with a triangle waveform. The metallic sound of the noise waveform is nice :).

Since there is an abundance of am'd square wave sounds everywhere, why not turn it into triangle waves? generated and then heavily edited using caustic 3. 2.
