Trumpet patch for the Nintendo Korg DS-10.
Actually harder than it sounds, the trumpet. Just one Voltage Controlled Oscillator (VCO) is used and it's a sawtooth waveform. Still wondering if there should be a 2nd oscillator though. Couldn't make it work any better with two.
The pitch has been raised one octave. I guess you could leave it at C4 and play higher notes.
The amplitude is modulated with a triangle wave, which gives some tremolo effect to the sound. Recall that vibrato is when you modulate the pitch and tremolo is when you modulate the amplitude.
