MIDI slider control banks
i1 ... i64 - output values
ichan - MIDI channel (1-16)
ictlnum1 ... ictlnum64 - MIDI control number
ictlno_msb1 .... ictlno_msb32 - MIDI control number (most significant byte)
ictlno_lsb1 .... ictlno_lsb32 - MIDI control number (least significant byte)
imin1 ... imin64 - minimum values for each controller
imax1 ... imax64 - maximum values for each controller
init1 ... init64 - initial value for each controller
ifn1 ... ifn64 - function table for conversion for each controller
icutoff1 ... icutoff64 - low-pass filter cutoff frequency for each controller
k1 ... k64 - output values
sliderN and sliderNf are banks of MIDI controller (useful when using MIDI mixer such as Kawai MM-16 or others for changing whatever sound parameter in real-time. A software slider bank will be available within short time). The raw MIDI control messages at the input port are converted to agree with iminN and imaxN, and an initial value can be set. Also, an optional non-interpolated function table with a custom translation curve is allowed, useful for enabling exponential response curves.
When no function table translation is required, set the ifnN value to 0, else set ifnN to a valid function table number. When table translation is enabled (i.e. setting ifnN value to a non-zero number referring to an already allocated function table), initN value should be set equal to iminN or imaxN value, else the initial output value will not be the same as specified in initN argument.
slider8 allows a bank of 8 different MIDI control message numbers, slider16 does the same with a bank of 16 controls, and so on.
sliderNf filter the signal before output, for eliminating discontinuities due to the low resolution of the MIDI (7 bit); the cutoff frequency can be set separately for each controller (suggested range: .1 to 5 Hz).
As the input and output arguments are many, you can split the line using '\' (backslash) character (new in 3.47 version) to improve the readability. Using these opcodes is considerably more efficient than using the separate ones (ctrl7 and tonek) when more controllers are required.
In the i-rate version of sliderN, there is not an initial value input argument, because the output is gotten directly from current status of internal controller array of Csound.
sNb14 opcode is the 14-bit version of this bank of controllers.
Warning! sliderNf opcodes do not output the required initial value immediately, but only after some k-cycles because the filter slightly delays the output.
The opcode names islider8, islider16, islider32, islider64, is16b14, and is32b14 have been deprecated as of Csound version 3.52. Use slider8, slider16, slider32, slider64, s16b14, and s32b14, respectively, for i-rate output.
