tuscland Member	posted 23 June 2006 10:13 Hello, I am trying to create an emulation of the Ralond JX3P synth. I have found a resource where the writer says : quote: http://www.retrosynth.com/gear/jx3p/info.html The JX-3P features two digitally clocked oscillators. The oscillators' frequency is derived from a master clock which is divided by an even integer to obtain a close approximate pitch. This method never allows the oscillators to produce a pure pitch across the entire range, and is probably accountable for the JX-3P's somewhat harsh sound. Does anybody knows how it is achieved? I can figure what frequency should be the master clock and how should it be divided? It seems like it is something simple, though ... Cheers, Camille IP: Logged
SSC Administrator	posted 23 June 2006 15:43 You could try this in the Frequency field of the Oscillator: !KeyPitch hz inverse samp That would convert the keyboard pitch to hertz. Inverting would give you seconds. Then convert it to samples. The result with be a frequency whose period is always an integer number of samples. IP: Logged
