Fletch Theme - Alesis Ion and Juno 106

There is another version here, on different synths: Using the Oscillator Sync feature on the Ion. Both oscillators use Square waves. You first hear Osc 1 (transposed 1 octave lower) and then I turn up the level knob for Osc 2 (transposed 1 octave higher, and full pitch modulated by LFO 2 at approx 2,3% with a 0,7-Hz rate). I also use the Unison mode to beef up the sound (4-voice unison, detuned by 5 semitones). The filter is wide open
