WindowsMidiStreamMBS.Close

WindowsMidiStreamMBS.Open(DeviceID as Integer)

By default, the device is opened in paused mode.
Lasterror is set.
DeviceID: The device is opened on behalf of the stream and closed again when the stream is closed.

WindowsMidiStreamMBS.Pause

Lasterror is set.

WindowsMidiStreamMBS.PositionBytes as Integer

Lasterror is set.

WindowsMidiStreamMBS.PositionMS as Integer

Lasterror is set.

WindowsMidiStreamMBS.PositionSamples as Integer

Lasterror is set.

WindowsMidiStreamMBS.PositionTicks as Integer

Lasterror is set.

WindowsMidiStreamMBS.Restart

Lasterror is set.

WindowsMidiStreamMBS.SendMessage(message as Integer)

dim o as WindowsMidiStreamMBS // your midi stream

// &h90 = Note down
// &h43 = the note number
// &h40 = the velocity
o.SendMessage &h404390

The message is stored in one 32bit integer.
lowest 8 bit is status, second 8 bit is data1, third 8 bit is data2 and highest 8 bit is left 0.

Between sending note on and off messages, you need to leave time for actual playback.
Lasterror is set.

// &h90 = Note down
// &h3C = the note number
// &h40 = the velocity
o.SendMessage &h90, &h3C, &h40

(Read and Write computed property)

WindowsMidiStreamMBS.TimeDiv as Integer

The low 16 bits of this integer value contain the time division.
Lasterror is set.

WindowsMidiStreamMBS.Volume as Integer

dim m as WindowsMidiStreamMBS // your midi stream

m.Volume=0 // all silent
m.Volume=&hFFFF0000 // right only
m.Volume=&h0000FFFF // left only or max volume for mono device
m.Volume=&h7FFF7FFF // half volume for both channels

Not all devices can set the volume.
Lasterror is set.

The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of &hFFFF represents full volume, and a value of &h0000 is silence.

If a device does not support both left and right volume control, the low-order word of dwVolume specifies the mono volume level, and the high-order word is ignored.
Lasterror is set.
