The RS130 will offer four preset scales and memory for one user-defined scale. It will have a range of 63 notes, plus a trigger output generator. There will be gated and "free" modes for a wide range of applications.

RS130 Programmable Scale Generator you should study the section of this manual that describes the philosophy and operation of a conventional Quantiser. You will find this in the chapter he rest of this chapter will assume that you have already done so, or that you are already fully acquainted with the ideas relating to voltage quantisation.

To recap, a Voltage Quantiser is a device that rounds (or " quantises") every voltage passing through it up or down to an exact sernitone. This means that any voltages output by the Quantiser will lie on one of the 12 sernitones of the conventional 'even-tempered' scale

A "Scale Generator" (or Scale Quantiser) takes this principal one step further: it quantises the signal in such a way that the output conforms to a predetermined musical scale. Examples of such scales are the common 'major' and 'minor' scales.

A programmable scale generator goes further still: while it may include predetermined scales as options, it also allows you to choose the notes that define any required scale. The RS130 is such a device.

Like the RS260, the RS130 incorporates software that ensures glitch-free transitions between quantised notes, and offers the same two timing modes. These are "Free Run", in which the output CV shifts every time the input changes enough to move from one note to another, and "Gate", which requires a pulse to tell the device when to detemine the next note.

But in addition to these, the R130 incorporates no fewer than six quantisation modes, and you must fully understand these if you are to get the best from the module."
