Used with the VST API to pass around plugin information.

Fields

magic: i32

Magic number. Must be ['V', 'S', 'T', 'P'].

dispatcher: DispatcherProc

Host to plug-in dispatcher.

_process: ProcessProc

Accumulating process mode is deprecated in VST 2.4! Use processReplacing instead!

setParameter: SetParameterProc

Set value of automatable parameter.

getParameter: GetParameterProc

Get value of automatable parameter.

numPrograms: i32

Number of programs (Presets).

numParams: i32

Number of parameters. All programs are assumed to have this many parameters.

numInputs: i32

Number of audio inputs.

numOutputs: i32

Number of audio outputs.

flags: i32

Bitmask made of values from api::flags.

use vst2::api::flags;
let flags = flags::CAN_REPLACING | flags::CAN_DOUBLE_REPLACING;
// ...

reserved1: isize

Reserved for host, must be 0.

reserved2: isize

Reserved for host, must be 0.

initialDelay: i32

For algorithms which need input in the first place (Group delay or latency in samples).

This value should be initially in a resume state.

_realQualities: i32

Deprecated unused member.

_offQualities: i32

Deprecated unused member.

_ioRatio: f32

Deprecated unused member.

object: *mut c_void

Void pointer usable by api to store object data.

user: *mut c_void

User defined pointer.

uniqueId: i32

Registered unique identifier (register it at Steinberg 3rd party support Web). This is used to identify a plug-in during save+load of preset and project.

version: i32

Plug-in version (e.g. 1100 for v1.1.0.0).

processReplacing: ProcessProc

Process audio samples in replacing mode.

processReplacingF64: ProcessProcF64

Process double-precision audio samples in replacing mode.

future: [u8; 56]

Reserved for future use (please zero).
