v2.00, December 6-8, 1996: Added Radio Drum id number to sysex messages and automatic position update.
v2.00 December 20 1996: Changed over to 3 byte sysex id scheme (Marion Systems id number)
v2.00 January 4 1997: display code, tilt mode

System Exclusive Messages

All the protocol System Exclusive Messages have the following structure:

[SYSEX START]
[sysex manufacturer code]: contains the manufacturer code (0x00,0x00,0x59; Marion Systems)
[command]: an opcode that specifies the command to be executed (0 .. 127)
[radio drum id]: this id allows more than one Radio Drum to be hooked up to the same MIDI port of a controlling computer. For each drum sharing the interface the user has to set the id code through the front panel and from then on they can be addressed separately. The default id code for a Radio Drum is "0". Sending a code of "0" is equivalent to sending the command to all Radio Drums sharing the same MIDI interface.
[body]: size depends on the specified command
[SYSEX END]

Turns ON the MIDI protocol program inside the Radio Drum. After receiving it, the Radio Drum sends back a "Turn Protocol ON" system exclusive message, starts to recognize poll and position update requests on the specified MIDI channel and transmits on that same channel baton trigger, release, switch (if it has been enabled to do so) and position information (see position polls and automatic periodic position updates).

Turn Protocol OFF

Turns OFF the MIDI protocol program inside the Radio Drum. After receiving it, the Radio Drum will wait for an appropriate system exclusive message to select its operation mode.

Each of the 16 measurements is sent as two MIDI bytes. The first one contains the 6 less significant bits of the measurement and the second contains the 6 most significant bits (the Radio Drum uses a 12 bit A/D converter).

Automatic Position Update Requests

Each of the requests starts an automatic update of position information to be sent by the Radio Drum at periodic intervals. The controller sent is used to differentiate between requests and the controller value is the time in ticks between periodic position updates (one tick equals 4 milliseconds). A time of cero turns off the selected automatic position update. Illegal times are ignored by the program and a reasonable default used (for example: periodic requests where the period is shorter than the time it takes to send the information).

Position Update Request for baton 1

Enables or disables (with period = 0) periodic position updates for baton 1. Cancels a previous request that involves both batons.

Position Update Request for baton 2

Enables or disables (with period = 0) periodic position updates for baton 2. Cancels a previous request that involves both batons.

Position Update Request for both batons

Enables or disables (with period = 0) periodic position updates for both batons. Cancels any previous individual requests for baton 1 or baton 2.
