Classic FM synthesis combined with ROM-based sounds make this vintage digital synthesizer a true classic (albeit challenging to master). TG77 patches should also work with SY77.
Slower attack, mellow with an emerging resonant overtone. Filter mapped to CC74.
Evolving voice. Harsh. Descending digital airplane. More than a minute long. Panning warbling sub frequencies. Shocking bright release.
Raw bass sound. Glitchy filter wobbles and adds depth. Filter mapped to CC74. At higher cutoff frequency sounds like a small static broken speaker sound.
