开云体育The TX81z Owner's Manual has a section (Waveform Harmonic Content, Pg. 50) that shows the eight waveforms and their harmonics.? Some of them have a high degree of 2nd-5th harmonic energy, and are roughly equivalent to modulating a sine operator with 2-4 others on the DX7.? Some of them also make interesting sounds on their own, with limited or no additional modulation; or combined together with slight detuning, to simulate an analog synth with multiple oscillators.The end results aren't quite the same, but I could make an argument that if the FM community as a whole had spent as much time programming the TX801z as the DX7, there might have been a lot more surprises to enjoy.? I performed for over three years with *nothing* but four -- yes, four -- TX81z modules in my rack., connected to a Roland MKB-300.? I used them for piano, EP, Clavinet, acoustic guitar, strings, organ, you name it.? In 2021 terms, the end results varied quite a bit -- some were quite realistic; others, less so -- but I could make the same critique of a DX5, DX7II, or TX802 vs. available modern gear.

If you can find the ad that ran for the TX81Z on the back of Keyboard magazine it had them pictured. One of them looked like two sine waves in phase with the frequency in one of them doubled, IIRC.

But maybe additional tweaking of the other four operators in algorithm structure simulating 4OP patch, in conjunction with those two operators can make it… I'm now meditating about the other interesting challenge - to imitate 6OP sounds on 4OP synth, at least on those able to layer two patches… :-) It would be difficult if not impossible to approximate non existing algorithms and key scaling, different envelopes… Daniel Forró-- Diese E-Mail wurde von Avast Antivirus-Software auf Viren geprüft. |
