Synthesis structure. The TS offered up to 6 oscillators per patch or sound. Each oscillator was processed by its own pitch, filter and amplifier blocks, with dedicated LFOs and envelope generators for each block. The architecture allowed various modulation sources, such as keyboard velocity, modulation and pitch wheels, etc. to modify several instances of the sonic chain. Despite the well-specified architecture, the filter didn't feature any kind of resonance. This limited the possibilities of emulating analog and heavily-filtered sounds. However, this was a common omission from several manufacturers of the early 1990s. The total 32-note polyphony was reduced when using more than one waveform per patch. The user patches could be stored in one of 120 memories, or saved to floppy disk.
