axis conversion byte position

Selects which databyte of the chosen midi message the converted value is placed in. For example, to

convert x-axis joystick input to control the pitch wheel, the generated message would consist of one

statusbyte and 2 databytes as follows: the statusbyte (indicating a pitch wheel message on midi

channel X), followed by the first databyte representing the LSB component of the pitch wheel message

(unused in this case since we can only provide an 8-bit value, therefore should be set to a value of

zero), followed by the second databyte representing the MSB value for pitch wheel. Hence you would

type 2 or scroll the parameter until it says “databyte #2” (to indicate that the value taken from the

gameport should be placed in the 2

databyte of the midi message). Since the statusbyte is not

considered a data byte, this parameter should be read in terms of databyte number, not byte number in

the cumulative message packet (i.e. 2 instead of 3). Possible databyte position values are either 1 or 2;

if set to zero (or “unused in msg”), the converted byte is not added to the midi message to be

transmitted (in this way, a fixed midi message will be generated).

Note that not all midi messages use both, or any, data bytes; channel aftertouch, program change, and

song select only use the first databyte (for aftertouch amount, program change number and song

number respectively), while system realtime messages such as midi clock simply use the statusbyte. As

converter automatically enforces these midi definitions, setting this byte position parameter to 2 when

the message type only supports one data byte results in the converted value not being a part of the

generated midi message.

axis statusbyte

Determines the midi message type (and channel) to use for the joystick conversion value. Possible

values are between 128 and 255.

axis 1

databyte value

Sets a fixed value for the first databyte of a midi message. The

conversion byte position

parameter

overrides this value if it is set to place the conversion result in the 1

databyte position.

axis 2

databyte value

Sets a fixed value for the second databyte of a midi message. The

conversion byte position

parameter overrides this value if it is set to place the conversion result in the 2

databyte position.

axis midi xmit

Determines whether the particular axis channel is used to generate midi data or not. This parameter is

useful if using the gameport input as a controller for converter’s own parameters (see section on control

functions), and it is preferable that it not generate midi data.
