![]() ![]() Two set of parameters on panels are used on 'tone mix' and 'key split' modes. ![]() It was possible to combine two non-resonant waveforms together, and to combine a resonant waveform with a non-resonant waveform, but it was not possible to combine two resonant waveforms. This could cause the appearance of a sub-harmonic one octave below the nominal pitch of the sound, due to the period of the combined waveform taking twice as long as a single waveform would. Unlike other synthesizers, where having multiple waveforms caused those multiple waveforms to be mixed together (parallel), the CZ synthesizers would play one waveform and then play the other, and so on in alternation (series). The simulated filter resonance was not considered to sound much like real filter resonance, being a simple waveform at the filter cutoff value instead of a real filter resonating.Įach digital oscillator could have one or two waveforms. It had in total eight different waveforms: as well as the standard sawtooth, square, and pulse waveforms, it had a special double sine waveform, a half-sine waveform, and three waveforms with simulated filter resonance: resonant sawtooth, triangle, and trapezoidal waveforms. However, the CZ line used phase distortion to simulate an analog filter. Like many early digital synthesizers, its sound was regarded as "thinner" than the sound of an analog synthesizer. ![]() ![]() To make the CZ synthesizers inexpensive, so they would be affordable to amateur musicians (a much larger market than the professional musician market), Casio used digital synthesis without a filter instead of traditional analog subtractive synthesis with a filter. Yukihiro Takahashi was also on board during development he then toured with a CZ-1 in 1986. Eight basic waveforms on Casio CZ series.Īlso non-resonant waveforms 1~5 can cascade with other waveforms, and as a result, 33 waveforms (basic:8, cascade:25) are available.Ĭasio's phase distortion synthesis technique was championed by Casio engineer Mark Fukuda and evolved from the Cosmo Synth System that was custom-developed for legendary synthesist-composer Isao Tomita. ![]()
