Custom Scale Definition Controls: Sgram/PT Dialog >> Pitch-to-MIDI >> Setup >> Scale
If you can't find the scale you want in the Scale List, you can create your own using the same format. Up to 4 custom scales are supported. The Custom Scale definitions all default to the equivalent of Chromatic... all notes are accepted. The default definition is thus CdDeEFgGaAbB. Any notes that you don't want to include in the custom scale should be replaced with spaces or periods to act as placeholders. (Minus signs or underscores will also work.) Important: This format uses position to determine the scale notes, not the specific letters you enter. Any alphanumeric character is regarded as a scale note at its position. Although all the standard scales in the scale list have 'C' set, this is not a requirement of custom scales (nor of scales you set via MIDI Changes script). When you enter a new scale pattern, the Num field shows the equivalent 12-bit number. Alternatively, you can specify the custom scale as a 12-bit number (1 to 4095) in the Num field, and the pattern field will be updated correspondingly. You can give your scale a meaningful name using the Custom Scale Name field. When you click on the button between the Definition and Name fields, that scale becomes the selected scale. The Scale button in the Voice Setup dialog will show the custom name. If the prior scale was a Scale List selection, the highlight will be removed from that list entry. There is no special Changes script command for custom scales; essentially, every Changes scale is "custom" since it is completely determined by the string you enter. Use Sv="string12" to set the Scale for MIDI Voice v to the string "string12". The string must be enclosed in quotes as shown, and must be 12 characters long. For example, S2="CdDeEFgGaAbB" sets Voice 2 to use a Chromatic (all notes) scale. Alternatively, you can create computed or random scales via Sv=n, which sets the Scale for voice v according to the bits set in value n, which may be any valid expression. Only the low 12 bits are used. Bit 11 (most-significant) represents C in the scale, and bit 0 represents B. If a bit is set, the corresponding note is included in the scale. You can select one of the Custom scales at random using the Siv=n format to select by index instead of by value. Index values from 0-531 are those scales in the List box, while 532-535 are the four Custom scales. For example, Si2=?(532,535) randomly selects one of the Custom scales for Voice 2.
